1、表格,隔行变色
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script> window.onload=function(){ var otab=document.getElementById('tb1') // otab.tBodies[0].rows[].cells[] var oldColor='' for (var i = otab.tBodies[0].rows.length - 1; i >= 0; i--) { if(i%2){ otab.tBodies[0].rows[i].style.background='red' }else{ otab.tBodies[0].rows[i].style.background='gray' } otab.tBodies[0].rows[i].onmouseover=function(){ oldColor=this.style.background this.style.background='green' } otab.tBodies[0].rows[i].onmouseout=function () { this.style.background=oldColor } } } </script> </head> <body> <!-- table[id='tb1' border="1" width="500">thead>td*3+tbody>(tr>td*3)*3 --> <table id="tb1" border="1" width="500"> <thead> <td>ID</td> <td>name</td> <td>age</td> </thead> <tbody> <tr> <td>1</td> <td>cxiong</td> <td>29</td> </tr> <tr> <td>2</td> <td>mm</td> <td>29</td> </tr> <tr> <td>3</td> <td>dd</td> <td>1</td> </tr> </tbody> </table> </body> </html>
2、表格的行的添加和删除
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script> window.onload=function(){ var otab=document.getElementById('tb1') // otab.tBodies[0].rows[].cells[] var ob=document.getElementById('b1') var oname=document.getElementById('name') var oage=document.getElementById('age') var id=otab.tBodies[0].rows.length+1 ob.onclick=function () { //创建tr元素 var otr=document.createElement('tr') //创建td元素 var otd=document.createElement('td') otd.innerHTML=id++ otr.appendChild(otd) var otd=document.createElement('td') otd.innerHTML=oname.value otr.appendChild(otd) var otd=document.createElement('td') otd.innerHTML=oage.value otr.appendChild(otd) var otd=document.createElement('td') otd.innerHTML='<a href="javascript:">delete</a>' otr.appendChild(otd) otd.getElementsByTagName('a')[0].onclick=function () { otab.tBodies[0].removeChild(this.parentNode.parentNode) } //添加元素 otab.tBodies[0].appendChild(otr) } } </script> </head> <body> <!-- table[id='tb1' border="1" width="500">thead>td*3+tbody>(tr>td*3)*3 --> name: <input type="text" id="name"> age: <input type="text" id="age"> <input type="button" id="b1" value="添加"> <table id="tb1" border="1" width="500"> <thead> <td>ID</td> <td>name</td> <td>age</td> <td>action</td> </thead> <tbody> <tr> <td>1</td> <td>cxiong</td> <td>29</td> </tr> <tr> <td>2</td> <td>mm</td> <td>29</td> </tr> <tr> <td>3</td> <td>dd</td> <td>1</td> </tr> </tbody> </table> </body> </html>
3、表格高亮、模糊、多关键字搜索
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script> window.onload=function(){ var otab=document.getElementById('tb1') var ot=document.getElementById('name') var ob=document.getElementById('b1') ob.onclick=function () { // body... for (var i = otab.tBodies[0].rows.length - 1; i >= 0; i--) { //转换小写toLowerCase() var arr=ot.value.toLowerCase().split(' ') otab.tBodies[0].rows[i].style.background='' // otab.tBodies[0].rows[i].style.display='none' //多关键字、模糊搜索 for (var j = arr.length - 1; j >= 0; j--) { if (otab.tBodies[0].rows[i].cells[1].innerHTML.toLowerCase().search(arr[j])!=-1) { otab.tBodies[0].rows[i].style.background='yellow' // otab.tBodies[0].rows[i].style.display='block' } } } } } </script> </head> <body> <!-- table[id='tb1' border="1" width="500">thead>td*3+tbody>(tr>td*3)*3 --> name: <input type="text" id="name"> <input type="button" value="search" id="b1"> <table id="tb1" border="1" width="500"> <thead> <td>ID</td> <td>name</td> <td>age</td> <td>action</td> </thead> <tbody> <tr> <td>1</td> <td>cxiong</td> <td>29</td> </tr> <tr> <td>2</td> <td>mm</td> <td>29</td> </tr> <tr> <td>3</td> <td>dd</td> <td>1</td> </tr> </tbody> </table> </body> </html>
4、表格排序
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script> window.onload=function(){ var ou1=document.getElementById('ul1') var ou2=document.getElementById('ul2') var ob=document.getElementById('b1') ob.onclick=function () { // body... // var oli=ou1.children[0] // ou1.removeChild(oli) // appendChile,先把元素从原有父级上删掉,添加到新的父级上 // ou1.appendChild(oli) // ou2.appendChild(oli) var ali=ou1.getElementsByTagName('li') var arr=[] for (var i = ali.length - 1; i >= 0; i--) { arr[i]=ali[i] } //排序:li中的内容innerHTML arr.sort(function(li1,li2){ return (parseFloat(li1.innerHTML)-parseFloat(li2.innerHTML)) }) //根据排序结果,添加li元素 for (var i = arr.length - 1; i >= 0; i--) { ou1.appendChild(arr[i]) } } } </script> </head> <body> <!-- table[id='tb1' border="1" width="500">thead>td*3+tbody>(tr>td*3)*3 --> <ul id="ul1"> <li>1</li> <li>22</li> <li>3</li> <li>14</li> </ul> <input type="button" value="sort" id="b1"> <ul id="ul2"> </ul> </body> </html>
5、表单
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script> window.onload=function(){ var of=document.getElementById('f1') of.onsubmit=function () { // body... alert("submit") } of.onreset=function(){ alert("reset") } } </script> </head> <body> <!-- table[id='tb1' border="1" width="500">thead>td*3+tbody>(tr>td*3)*3 --> <form id="f1" action="www.baidu.com" method="get" accept-charset="utf-8"> 用户名: <input type="text" name="user"> <br> 密码: <input type="text" name="password" value=""><br> <input type="submit" value="提交"> <input type="reset" value="重置"> </form> </body> </html>
