通过创建节点,添加表单,最后添加到body子标签中

function htmlPost(){
  var data = {"test","测试"}
  myPost("url",data)
}
function myPost(url, params) {
var temp = document.createElement("form");
temp.action = url;
temp.method = "post";
temp.style.display = "none";
for (var x in params) {
var opt = document.createElement("textarea");
opt.test = x;
temp.appendChild(opt);
}
document.body.appendChild(temp);
temp.submit();
return temp;
}
