代碼如下:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>jquery xml解析</title>
<script src="jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
$.ajax({url:"City.xml",
success:function(xml){
$(xml).find("province").each(function(){
var t = $(this).attr("name");//this->
$("#DropProvince").append("<option>"+t+"</option>");
});
}
});
$("#DropProvince").change(function(){
$("#sCity>option").remove();
var pname = $("#DropProvince").val();
$.ajax({url:"City.xml",
success:function(xml){
$(xml).find("province[name='"+pname+"']>city").each(function(){
$("#sCity").append("<option>"+$(this).text()+"</option>");
});
}
});
});
});
</script>
</head>
<body>
<form id="form1">
<div>
<select id="DropProvince" style="width:60px;">
<option>請選擇</option>
</select>
<select id="sCity" style="width:60px;">
</select>
</div>
</form>
</body>
</html>
city.xml文件
代碼如下:
<?xml version="1.0" encoding="utf-8" ?>
<provinces>
<province name="湖北">
<city>武漢</city>
<city>黃石</city>
<city>宜昌</city>
<city>天門</city>
</province>
<province name="湖南">
<city>邵陽</city>
<city>長沙</city>
<city>岳陽</city>
</province>
<province name="廣東">
<city>廣州</city>
<city>深圳</city>
</province>
</provinces>
其實主要是注意怎樣在html界面上解析xml文件，格式就是
代碼如下:
<script type="text/javascript">
$(document).ready(function () {
$.ajax({
url: "City.xml",
success: function (xml) {
$(xml).find("province").each(function () {
var t = $(this).attr("name");
$("#DropProvince").append("<option>" + t + "</option>");
});
}
});
$("#DropProvince").change(function () {
$("#sCity>option").remove();
var pname = $("#DropProvince").val();
$.ajax({
url: "City.xml",
success: function (xml) {
$(xml).find("province[name='"+pname+"']>city").each(function(){
$("#sCity").append("<option>"+$(this).text()+"</option>");
});
}
});
});
});
</script>
就是用$.ajax()調用xml文件的內容。然后$.each()進行循環操作，基本思想就是這樣的，成功之后去執行success這個回調函數。這里的xml文件是用來存儲數據的，相當于在數據庫中讀取文件。
