if(document.getElementByIdx_x("topLoadingDiv")!='null'&&document.getElementByIdx_x("topLoadingDiv")!=undefined) {
document.getElementByIdx_x("topLoadingDiv").className="top_loaded";

3、用到的html
// 调用ajax之前
topLoading();
$.getJSON(url,null,function(data) {
obj.disabled=false;
if (data == "error") {
alert(opeContent+"失败!");
} else if (data == "succ"){
// 2、根据返回结果(成功或者失败),重写load该流程对应的所有组件
alert(opeContent+"成功!");
reloadListDetail(obj);
} else {
alert(data);
reloadListDetail(obj);
}
// ajax返回之后
