之前一直困扰在如何用js解析xml文件，从网上也找了好多方法，代码很多，自己也理不清楚，终于有大神帮助，教我用ajax来读取和解析xml，感觉收获颇多，直接上代码
function ajaxRequest() {
$.ajax({
type : 'GET',url : "static/download/data/data.xml",success : function(xml) {
var strleft = '<dt>下载分类</dt>';
var j = 1;
$(xml).find("item").each(function() { //遍历第一层
var itemname = $(this).attr("name");
var subitem = "";
$(this).children("download").each(function() { //遍历第二层
subitem += '<li class="downitem"><a title="点击下载" href="';
subitem +=$(this).attr("url");
subitem +='">';
subitem += $(this).attr("name");
subitem += '</a></li>';
});
var num=$(this).children("download").length;
strleft += '<dd ><a href="#" onclick="item_method('+ j + ','+num+')">';
strleft += itemname;
strleft += '</a></dd>';
$("#item" + j).html(subitem);
if (j != 1) {
$("#item" + j).hide();
}
j += 1;
});
$("#leftmenu").html(strleft);
},error : function() {
}
});
}上面的方法就是解析xml的方法了，在初始js里调用即可
$(document).ready(function() {
ajaxRequest();
});
再把xml一起附上，以便参考
<?xml version="1.0" encoding="utf-8" ?> <items> <item name="案例下载"> <download name="案例1" url="http://36.21.0.1:8080/nav/index.html"></download> <download name="案例2" url="http://36.21.0.1:8080/map/index.html"></download> <download name="案例3" url="http://36.21.0.1:8080/cqexchange/"></download> </item> <item name="类库下载"> <download name="类库1" url="http://36.21.0.1:8080/nav/index.html"></download> <download name="类库2" url="http://36.21.0.1:8080/map/index.html"></download> <download name="类库3" url="http://36.21.0.1:8080/cqexchange/"></download> <download name="类库4" url="http://36.21.0.1:8080/cqexchange/datapublish.html"></download> <download name="类库5" url="http://36.21.0.1:8080/devcenter/"></download> <download name="类库6" url="http://36.21.0.1:8080/devcenter/"></download> </item> <item name="说明文档下载"> <download name="文档1" url="http://36.21.0.1:8080/nav/index.html"></download> <download name="文档2" url="http://36.21.0.1:8080/map/index.html"></download> <download name="文档3" url="http://36.21.0.1:8080/cqexchange/"></download> <download name="文档4" url="http://36.21.0.1:8080/cqexchange/datapublish.html"></download> <download name="文档5" url="http://36.21.0.1:8080/devcenter/"></download> </item> <item name="其他下载"> <download name="其他1" url="http://36.21.0.1:8080/nav/index.html"></download> <download name="其他2" url="http://36.21.0.1:8080/map/index.html"></download> </item> </items>
