//调用方法 如
post('pages/statisticsJsp/excel.action', {html :prnhtml,cm1:'sdsddsd',cm2:'haha'});
post方式提交参数并下载文件:
正常情况下下载用windows.open(URL)
,若想用post传参可以用如下方式,生成action为URL的表格,然后利用form传参并跳转,由于跳转URL实际上是被下载的文件,所以浏览器会开始下载并保留原来页面(不确定?)。
var temp = document.createElement("form");
temp.action = "catalogDetail.do?method=Download";
temp.method = "post";
temp.style.display = "none";
var PARAMS = {
"cata_id" : $("input[name='cata_id']").val(),
"where" : filter_condition.where,
"columns" : $("#gaojishaixuan_fenzu_column").val()
};
for (var x in PARAMS) {
var opt = document.createElement("textarea");
opt.name = x;
opt.value = PARAMS[x];
temp.appendChild(opt);
}
document.body.appendChild(temp);
temp.submit();
$(temp).remove();
