本篇内容主要讲解"html如何写post请求",感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷,实用性强。下面就让小编来带大家学习"html如何写post请求"吧!
1.为什么要用post请求?
因为在我们使用post请求的时候用户在涉及有关于密码和隐私的内容时,不会在地址栏上面看到我们的内容起到了保护作用,所以这就是为什么要使用post请求的原因。
2.方法一:
我们通过使用传统的方式来对浏览器进行post请求,代码如下:
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);
3.方法二:
采用虚拟表单进行提交post请求,代码如下:
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'});到此,相信大家对"html如何写post请求"有了更深的了解,不妨来实际操作一番吧!这里是网站,更多相关内容可以进入相关频道进行查询,关注我们,继续学习!
