这篇文章将为大家详细讲解有关jQuery中轻量级表单模型验证插件的示例分析,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。
JQuery插件,轻量级表单模型验证,供大家参考,具体内容如下
var validataForm = (function(model) {
model.Key = "[data-required='true']";
model.ElementList = new Array();
model.FunctionDictionary = new Dictionary();
model.ToastrCustom = function (msg) {
alert(msg);
}
model.AddElement = function (name) {
model.ElementList.push(name);
};
model.AddFunction = function (name, func) {
model.FunctionDictionary.add(name, func);
};
model.Validata = function (formName) {
for (var i = 0; i < model.ElementList.length; i++) {
var thisObj = model.ElementList[i];
var str = formName + " " + thisObj + model.Key;
var elements = $(str);
for (var j = 0; j < elements.length; j++) {
var element = elements.eq(j);
var value = element.val();
var elementType = element.data().type;
var func = model.FunctionDictionary.find(elementType);
if (func) {
var result = func(value, element);
if (result.status) {
var errorInfo = result.message;
model.ToastrCustom(errorInfo);
return;
}
}
}
}
};
model.ElementList.push("input");
model.ElementList.push("select");
model.FunctionDictionary.add("required", function (value, element) {
var name = element.data().name;
return {
status: (value === ""),
message: (value === "" && name + "不能为空")
};
});
return model;
})(window.validataForm || {});
调用处
<form id="ValidataForm">
<input data-required="true" data-name="名称" data-type="required" value="">
<input data-required="true" data-name="昵称" data-type="hello">
<button id="Send">提交</button>
</form>
<script src="~/js/plugs/jquery-3.3.1.js"></script>
<script src="~/js/Dictionary.js"></script>
<script src="~/js/ValidataForm.js"></script>
<script type="text/javascript">
$("#Send").click(function () {
validataForm.Validata("#ValidataForm");
});
</script>
Dictionary这个对象是抄一个博主的
代码附上,内置链接

/*字典 Dictionary类*/
function Dictionary() {
this.add = add;
this.datastore = new Array();
this.find = find;
this.remove = remove;
this.count = count;
this.clear = clear;
}
function add(key, value) {
this.datastore[key] = value;
}
function find(key) {
return this.datastore[key];
}
function remove(key) {
delete this.datastore[key];
}
function count() {
/*var ss = Object.keys(this.datastore).length;
console.log("ssss "+ss);
return Object.keys(this.datastore).length;*/
/**/
var n = 0;
for (var key in Object.keys(this.datastore)) {
++n;
}
return n;
}
function clear() {
for (var key in this.datastore) {
delete this.datastore[key];
}
}
