一个能搜索的表格

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
<style>
.table{width:100%; border:1px solid #eee; border-collapse:collapse;}
.table > tbody > tr{}
.table > tbody > tr > td{text-align:center; border:1px solid #eee;}
</style>
<script>
window.onload = function(){
    var testTable = document.getElementById("testTable");
    var txt = document.getElementById("s_text");
    var btn = document.getElementById("search");

    btn.onclick = function(){
        for(var i=0;i<testTable.tBodies[0].rows.length;i++){
            if(testTable.tBodies[0].rows[i].cells[1].innerHTML.toLowerCase() == txt.value.toLowerCase()){
                testTable.tBodies[0].rows[i].style.background = "yellow";
            }else{
                testTable.tBodies[0].rows[i].style.background = "";
            }
        }
    };

};
</script>
</head>

<body>
    test:<input id="s_text" type="text" />
    <input id="search" type="button" value="Search" />
    <table class="table" id="testTable">
        <thead>
            <tr>
                <th>test</th>
                <th>test</th>
                <th>test</th>
                <th>option</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td>test1</td>
                <td>test2</td>
                <td>test3</td>
                <td></td>
            </tr>
            <tr>
                <td>test4</td>
                <td>test5</td>
                <td>test6</td>
                <td></td>
            </tr>
            <tr>
                <td>test1</td>
                <td>test2</td>
                <td>test3</td>
                <td></td>
            </tr>
            <tr>
                <td>test4</td>
                <td>test5</td>

            </tr>
            <tr>
                <td>test1</td>
                <td>test2</td>
                <td>test3</td>
                <td></td>
            </tr>
        </tbody>
    </table>
</body>
</html>

除此之外还可以使用search()进行模糊搜索，用split()进行多关键词搜索。

我们可以对表格提供排序服务，我们可以模拟一个List，Table和它的写法一样。

<!DOCTYPE html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<script>
window.onload = function(){
    var nl = document.getElementById("numberList");
    var btn = document.getElementById("order");

    btn.onclick = function(){
        var aLi = nl.getElementsByTagName("li");

        var arr = [];

        for(var i=0;i<aLi.length;i++ ){
            arr[i] = aLi[i];
        }

        arr.sort(function(l1,l2){
            var n1 = parseInt(l1.innerHTML);
            var n2 = parseInt(l2.innerHTML);

            return n1 - n2;
        });

        for(var i=0;i<arr.length;i++){
            nl.appendChild(arr[i]);
        }
    };
};
</script>
</head>

<body>
    <input id="order" type="button" value="Order" />
    <ul id="numberList">
        <li>21</li>
        <li>88</li>
        <li>45</li>
        <li>17</li>
