city.xml文件
<?xml version="1.0" encoding="utf-8" ?> <provinces> <province name="湖北"> <city>武汉</city> <city>黄石</city> <city>宜昌</city> <city>天门</city> </province> <province name="湖南"> <city>邵阳</city> <city>长沙</city> <city>岳阳</city> </province> <province name="广东"> <city>广州</city> <city>深圳</city> </province> </provinces>
其实主要是注意怎样在html界面上解析xml文件，格式就是
<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$.ajax()调用xml文件的内容。然后$.each()进行循环操作，基本思想就是这样的，成功之后去执行success这个回调函数。这里的xml文件是用来存储数据的，相当于在数据库中读取文件。
