一，引言
工作的需要，做了3年的wpf(mvvm)……，又因为项目的需求，回归到web的开发。
二，项目的前端（easyui模板订制）
整个项目采用了oracle + dapper + castle + mvc + easyui的技术结合，本篇博客重点介绍easyui。
easyui的默认风格看久了很容易产生视觉疲劳，在这个项目中，我个性化订制风格。
订制easyui模板的工作量是挺大的，我用了一个偷懒的方法，花了几百块钱在网上买了几个easyui的皮肤，然后对这些皮肤，进行优化和重构。
money比较紧的同学，可以去下载easyui的免费皮肤。
三，easyui-datagrid的基本使用：
1，加载数据
a，通过post，url的方法向后端请求数据，如图所示：
$('#List').datagrid({
title: "交易公司",
loadMsg: '@CommonResource.Processing',
toolbar: '#tb',
width: "100%",
height: "100%",
//idField:"ID",
//data: getData(),
url: "@Url.Action("GetList")",
methord: 'post',
rownumbers: true,
autoRowHeight: false,
fit: true,
//fitColumns: true,
striped: true, //奇偶行
singleSelect: true,//单选模式
checkOnSelect: false,
selectOnCheck: false,
collapsible: true,
pagination: true,
pageNumber: 1,
pageSize: 10,
pageList: [10, 20],
queryParams: { },
columns: [[
{ field: 'Company_Name', title: '公司名称', width: 100, sortable: false },
{ field: 'Abbreviation', title: '简称', width: 100, sortable: false },
{ field: 'Business_Address', title: '经营地址', width: 100, sortable: false },
{ field: 'Registered_Address', title: '注册地址', width: 100, sortable: false },
{ field: 'Tel', title: '电话', width: 100, sortable: false },
{ field: 'Fax', title: '传真', width: 100, sortable: false },
{ field: 'Contactor', title: '联系人', width: 100, sortable: false },
{ field: 'Payment', title: '结算方式', width: 100, sortable: false },
{ field: 'Beneficiary_Name', title: '开户名称', width: 100, sortable: false },
{ field: 'Beneficiary_Address', title: '开户地址', width: 100, sortable: false },
{ field: 'Advising_Bank', title: '通知行', width: 100, sortable: false },
{ field: 'Bank_Address', title: '银行地址', width: 100, sortable: false },
{ field: 'Swift_Code', title: '银行代码', width: 100, sortable: false },
{ field: 'Beneficiary_Account', title: '银行账户', width: 100, sortable: false },
{ field: 'Company_Chop', title: '电子章', width: 100, sortable: false },
{ field: 'Send_Url', title: '发件邮箱链接', width: 100, sortable: false },
{ field: 'Send_Email', title: '发件人邮箱', width: 100, sortable: false },
{ field: 'Remark', title: '备注', width: 100, sortable: false },
{ field: 'Created_By', title: '创建人', width: 100, sortable: false },
{ field: 'Creation_Date', title: '创建日期', width: 100, sortable: false },
{ field: 'Modify_By', title: '修改人', width: 100, sortable: false },
{ field: 'Modify_Date', title: '修改日期', width: 100, sortable: false },
]],
});
});
b，先定义好了datagrid的属性以及列，再通过loadData的方法设置datagrid的数据
$('#Detail').datagrid({
loadMsg: '@CommonResource.Processing',
toolbar: '#tb',
width: "100%",
height: "100%",
//data: [],
rownumbers: true,
autoRowHeight: false,
fit: true,
fitColumns: true,
striped: true,
singleSelect: true,
collapsible: false,
pagination: false,
queryParams: { },
columns: [[
{ field: 'Country_Name', title: '国家名称', width: 100, sortable: false },
{ field: 'Item_Number', title: '物料编码', width: 100, sortable: false },
]],
});
var returnData = JSON.parse(response.data);
$('#Detail').datagrid("loadData", returnData);
2，合并单元格
有时候用户需要如下图的效果
可以在datagrid的onLoadSuccess事件里增加如下代码：
onLoadSuccess: function (data) {
//var opts = $('#List').datagrid('getColumnFields');
var opts = new Array("Item_Number", "Country_Name", "Item_Desc", "Item_Desc_En", "Item_Type", "Unit", "Hs_Code", "Destination_Code", "Status", "Remark", "Create_User", "Create_Date");
var rowsCount = data.rows.length;
var mark = 1;
for (var j = 1; j < rowsCount; j++)
{
var preCellVal = data.rows[j - 1]["Material_Id"];
var currentCellVal = data.rows[j]["Material_Id"];
if (preCellVal == currentCellVal) {
mark += 1;
for (var c = 0; c < opts.length; c++) {
var columnName = opts[c];
$(this).datagrid('mergeCells', {
field: columnName,
index: j + 1 - mark,
rowspan: mark
});
}
}
else {
mark = 1;
}
}
},
3，行，列变色
针对这样的行，列变色效果：
a，行变色
$('#Detail').datagrid({
loadMsg: '@CommonResource.Processing',
toolbar: '#tb',
width: "100%",
height: "100%",
url: "@Url.Action("GetLines")",
methord: 'post',
rownumbers: true,
autoRowHeight: false,
fit: true,
fitColumns: true,
striped: true,
singleSelect: true,
collapsible: false,
pagination: false,
queryParams: { hid: $("#Hid").val() },
columns: [[
{ field: 'Material_No', title: '物料号', width: 100, sortable: false },
{ field: 'Description', title: '中文描述', width: 100, sortable: false },
{ field: 'En_Description', title: '英文描述', width: 100, sortable: false },
{ field: 'Unit', title: '单位', width: 100, sortable: false },
{ field: 'Quantity', title: '工单数量', width: 100, sortable: false },
{ field: 'Total_Actual_Send_Quantity', title: '已出货数量', width: 100, sortable: false },
{ field: 'Remark', title: '备注', width: 100, sortable: false },
]],
rowStyler: function (index, row) {
if (row.Quantity == 0) {
return 'background-color:pink;color:blue;font-weight:bold;';
}
},
});
b，列变色
$('#Detail').datagrid({
loadMsg: '@CommonResource.Processing',
width: "100%",
height: "100%",
data: [],
rownumbers: true,
autoRowHeight: false,
fit: true,
fitColumns: true,
striped: true,
singleSelect: true,
checkOnSelect: false,
selectOnCheck: false,
collapsible: false,
pagination: false,
queryParams: {},
columns: [[
{ field: 'sel', checkbox: true },
{ field: 'Material_No', title: '物料号', width: 80, sortable: false },
{ field: 'Description', title: '中文描述', width: 80, sortable: false },
{ field: 'Unit', title: '单位', width: 80, sortable: false },
{ field: 'Quantity', title: '工单数量', width: 80, sortable: false },
{ field: 'Total_Actual_Send_Quantity', title: '已出货数量', width: 80, sortable: false },
{ field: 'Remain_Quantity', title: '剩余数量', width: 80, sortable: false },
{
field: 'Actual_Send_Quantity', title: '本次出货', width: 80, sortable: false,
editor: { type: 'numberbox', options: { required: true, min: 0 }, },
styler: function (value, row, index) {
return 'background-color:#ecffff;';
},
},
{
field: 'Remark', title: '备注', width: 80, sortable: false,
editor: { type: 'textbox', options: { validType: 'length[1,20]' }, },
styler: function (value, row, index) {
return 'background-color:#ecffff;';
},
},
]],
4，为datagrid添加工具条
如下效果的工具条，是通过datagrid的 toolbar 属性来指定，要留意的是toolbar的控件名称需要加上#符号。
html代码：
<div id="tb">
<a id='condition' href='#' class='btn btn-default more'><i class='fa fa-ellipsis-v'></i> 查询条件</a>
@Html.ToolButton(string.Format(@"<a id='btnCreate' href='#' class='btn btn-default'><i class='fa fa-plus'></i> {0}</a>", @CommonResource.Add), ActionCode.Create)
@Html.ToolButton(string.Format(@"<a id='btnEdit' href='#' class='btn btn-default'><i class='fa fa-pencil'></i> {0}</a>", @CommonResource.Edit), ActionCode.Edit)
@Html.ToolButton(string.Format(@"<a id='btnDelete' data-content='Delete 1' href='#' class='btn btn-primary'><i class='fa fa-trash'></i> {0}</a>", @CommonResource.Delete), ActionCode.Delete)
</div>
js代码：
5，做增，删，改操作
a,为datagrid增加一行
function addCallBack(data) {
$('#List').datagrid('insertRow', {
index: 0,
row: data,
});
layer.msg('@CommonResource.AddSuccess', { icon: 1, time: 1000 });
}
b,为datagrid编辑一行
function editCallBack(data) {
var selectData = $('#List').datagrid('getSelected');
var selectIndex = $('#List').datagrid('getRowIndex', selectData);
$('#List').datagrid('updateRow', {
index: selectIndex,
row: data,
});
layer.msg('@CommonResource.ModifySuccess', { icon: 1, time: 1000 });
}
c,为datagrid删除一行
$("#btnLineDelete").click(function () {
var row = $('#Detail').treegrid('getSelected');
if (row != null) {
var rowIndex = $('#Detail').datagrid('getRowIndex', row);
$('#Detail').datagrid('deleteRow', rowIndex);
layer.msg('@CommonResource.DeleteSuccess', { icon: 1, time: 1000 });
}
else {
layer.msg('@CommonResource.Noselectedrecord', { icon: 2, time: 1000 });
}
});
d,treegrid的操作方法略有区别，附上源码：
function addCallBack(data) {
var row = $('#List').treegrid('getSelected');
$('#List').treegrid('append', {
parent: data.Parent_Id,
data: [{
Id: data.Id,
Name: data.Name,
En_Name:data.En_Name,
Code: data.Code,
Enable: data.Enable,
Sort: data.Sort,
}]
});
layer.msg('@CommonResource.AddSuccess', { icon: 1, time: 1000 });
}
function editCallBack(data) {
var row = $('#List').treegrid('getSelected');
$('#List').treegrid('update', {
id: row.Id,
row: {
Name: data.Name,
En_Name: data.En_Name,
Code: data.Code,
Enable: data.Enable,
Sort: data.Sort,
}
});
layer.msg('@CommonResource.ModifySuccess', { icon: 1, time: 1000 });
}
$("#btnDelete").click(function () {
var row = $('#List').treegrid('getSelected');
if (row != null) {
layer.confirm('@CommonResource.ConfirmDelete', {
btn: ['@CommonResource.Sure', '@CommonResource.Cancel'],
shadeClose: true,
}, function () {
if (row.ChildCount == 0 || typeof (row.ChildCount) == 'undefined') {
$.post("@Url.Action("Delete")/" + row.Id, function (data) {
if (data == "1") {
$("#List").treegrid('remove', row.Id);
layer.msg('@CommonResource.DeleteSuccess', { icon: 1, time: 1000 });
}
else {
layer.msg('@CommonResource.DeleteFailed', { icon: 2, time: 1000 });
}
}, "json");
}
else {
layer.msg('@CommonResource.Noselectedrecord', { icon: 2, time: 1000 });
}
}, function () {
});
}
else {
layer.msg('@CommonResource.Noselectedrecord', { icon: 2, time: 1000 });
}
});
6，编辑单元格
具体代码实现
var taxTypeList = JSON.parse($("#taxTypeList").val());
var manufactureList = JSON.parse($("#manufactureList").val());
$.extend($.fn.datagrid.methods, {
editCell: function (jq, param) {
return jq.each(function () {
var opts = $(this).datagrid('options');
var fields = $(this).datagrid('getColumnFields', true).concat($(this).datagrid('getColumnFields'));
for (var i = 0; i < fields.length; i++) {
var col = $(this).datagrid('getColumnOption', fields[i]);
col.editor1 = col.editor;
if (fields[i] != param.field) {
col.editor = null;
}
}
$(this).datagrid('beginEdit', param.index);
for (var i = 0; i < fields.length; i++) {
var col = $(this).datagrid('getColumnOption', fields[i]);
col.editor = col.editor1;
}
});
}
});
var editIndex = -1;
function endEditCal() {
if (editIndex == -1) {
return true;
}
if ($('#Detail').datagrid('validateRow', editIndex)) {
$('#Detail').datagrid('endEdit', editIndex);
editIndex = -1;
return true;
}
else {
return false;
}
}
$('#Detail').datagrid({
loadMsg: '@CommonResource.Processing',
toolbar: '#tb',
width: "100%",
height: "100%",
data: JSON.parse($("#MaterialDetailListStr").val()),

formatter: function (value) {
for (var i = 0; i < manufactureList.length; i++) {
if (manufactureList[i].Key == value) return manufactureList[i].Value;
}
return value;
},
editor: {
type: 'combobox',
options: {
valueField: 'Key',
textField: 'Value',
data: manufactureList,
required: true,
panelHeight: "auto",
editable:false,
}
},
},
{
field: 'Tax_Type', title: '税别', width: 100, sortable: false,

for (var i = 0; i < taxTypeList.length; i++) {
if (taxTypeList[i].Key == value) return taxTypeList[i].Value;
}
return value;
},

},
},
{ field: 'Tax_Bcd', title: 'BCD', width: 100, sortable: false, editor: { type: 'numberbox', options: { required: true, suffix: '%', precision: 2, min: 0, max: 100, } } },
{ field: 'Tax_Cess', title: 'CESS', width: 100, sortable: false, editor: { type: 'numberbox', options: { required: true, suffix: '%', precision: 2, min: 0, max: 100, } } },
{ field: 'Tax_Igst', title: 'IGST', width: 100, sortable: false, editor: { type: 'numberbox', options: { required: true, suffix: '%', precision: 2, min: 0, max: 100, } } },
]],
@if (Request.Params["Operate"] != "View")
{
<text>
onClickCell: function (index, field, value) {
if (endEditCal()) {
$(this).datagrid('selectRow', index).datagrid('editCell', { index: index, field: field }); //编辑一个单元格
//$(this).datagrid('beginEdit', index); //编辑一行
editIndex = index;
}
else {
layer.msg('当前行的数据编辑有误', { icon: 2, time: 1000 });
}
},
onAfterEdit: function (index, row, changes) {
var rowData = $(this).datagrid('getData').rows[index];
$('#Detail').datagrid('updateRow', {
index: index,
row: {},
});
},

for (var index = 0; index < data.rows.length; index++) {
$(this).datagrid('beginEdit', index);
}
},
</text>
}
});
$("#btnLineCreate").click(function () {
if (endEditCal()) {
editIndex = 0;
$('#Detail').datagrid('insertRow', {
index: editIndex,
row: {},
});
$('#Detail').datagrid('selectRow', editIndex);
$('#Detail').datagrid('beginEdit', editIndex);
}
else {
layer.msg('当前行的数据编辑有误', { icon: 2, time: 1000 });
}
});
$("#btnLineDelete").click(function () {
var row = $('#Detail').treegrid('getSelected');
if (row != null) {
var rowIndex = $('#Detail').datagrid('getRowIndex', row);
$('#Detail').datagrid('deleteRow', rowIndex);
layer.msg('@CommonResource.DeleteSuccess', { icon: 1, time: 1000 });
}
else {
layer.msg('@CommonResource.Noselectedrecord', { icon: 2, time: 1000 });
}
});
$("#btnSave").click(function () {
var summaryValidate = true;
var rows = $("#Detail").datagrid("getRows");
$(rows).each(function (index, itemData) {
if ($('#Detail').datagrid('validateRow', index)) {
$('#Detail').datagrid('endEdit', index);
}
else {
summaryValidate = false;
return false;
}
});
if (summaryValidate) {
if (rows.length == 2) {
$("#MaterialDetailListStr").val(JSON.stringify(rows));
}
else {
layer.msg('税别,用途应该设置为2行数据', { icon: 2, time: 1000 });
return false;
}
}
else {
layer.msg('当前表单数据编辑有误', { icon: 2, time: 1000 });
return false;
}
var check = $('form').form('validate');
if (check) {
$.ajax({
url: "@Url.Action("CreateMaterial")",
type: "Post",
data: $("form").serialize(),
dataType: "json",
success: function (data) {
if (data.Key == "1") {
parent.$("#List").datagrid('reload');
var index = parent.layer.getFrameIndex(window.name);
parent.layer.close(index);
parent.layer.msg('@CommonResource.AddSuccess', { icon: 1, time: 1000 });
}
else {
layer.msg("物料编号'" + data.Value.Item_Number + "'在数据库中已添加", { icon: 2, time: 1000 });
}
},
error: function (jqXHR, textStatus, errorThrown) {
layer.msg('@CommonResource.AddFailed', { icon: 2, time: 1000 });
}
});
}
});
7，重置datagrid布局 $('#List').datagrid("resize");
$(function () {
$(".more").click(function () {
$(this).closest(".conditions").siblings().toggleClass("hide");
$('#List').datagrid("resize");
});
})
四，总结
这些技巧，在帮助文档里也说的很详细，我只是把这些技术用于实践。希望对大家的学习有所帮助，也希望大家多多支持亿速云。
