JS模拟表单提交

     function Post(URL, param) {
        //创建form表单
        var temp_form = document.createElement("form");
        temp_form.action = URL;
        //如需打开新窗口，form的target属性要设置为'_blank'
        temp_form.target = "_self";
        temp_form.method = "post";
        temp_form.style.display = "none";
        //添加参数
         for (var item in param) {
             var opt = document.createElement("input");//添加一个input类型
             opt.name = item;
             opt.value = param[item];
             temp_form.appendChild(opt);
         }
        //提交数据
        temp_form.submit();
    }
