ajax当状态为"json"时，服务端返回回来若不是json格式则不执行操作，切记。。。

<span style="white-space:pre">	</span>function xxx(){
$.ajax({
url:basePath + "/themeMsg/getInitData.do",
type:"POST",
data:{},
cache:false,
dataType:'json',
success:function(data){
var html = "";
$(".header-txt > a").attr('href',data.downloadSoftUrl);

$.each(data.hotKeys, function(i,item){
html += "<a href=" + basePath + "/themeMsg/searchThemesByHotKey.do?hotname=" + item.hotname+">" + item.hotname +"</a>";
});
$(".hot-label").append(html);

if(data.isClose == "true"){
$(".header.header-2.clearfix").hide();
}
}
});
}
