第一种提交post的方式是传统方式，判断浏览器进行post请求。
var postData = {
"name1": "value1",
"name2": "value2"};
postData = (function(obj){ // 转成post需要的字符串.
var str = "";
for(var prop in obj){
str += prop + "=" + obj[prop] + "&"
}
return str;
})(postData);
var xhr = new XMLHttpRequest();
xhr.open("POST", "../module", true);
xhr.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xhr.onreadystatechange = function(){
var XMLHttpReq = xhr;
if (XMLHttpReq.readyState == 4&&XMLHttpReq.status == 200) {
var text = XMLHttpReq.responseText;
console.log(text);
}
};
xhr.send(postData);
第二种方式则是虚拟表单的形式提交post请求
function post(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.name = x;
opt.value = PARAMS[x];
// alert(opt.name)
temp.appendChild(opt);
}
document.body.appendChild(temp);
temp.submit();
return temp;
}
调用方法 如
post('pages/statisticsJsp/excel.action', {html :prnhtml,cm1:'sdsddsd',cm2:'haha'});
