复制代码代码如下:

var form=$("<form>");//定义一个form表单
form.attr("style","display:none");
form.attr("target","");
form.attr("method","post");
form.attr("action","exportData");
var input1=$("<input>");
input1.attr("type","hidden");
input1.attr("name","exportData");
input1.attr("value",(new Date()).getMilliseconds());
$("body").append(form);//将表单放置在web中
form.append(input1);
