The examples in this article describe two ways of using post submission in JS. Share it with everyone for your reference, the details are as follows:
The first way to submit a post is the traditional way, which judges the browser to make a post request.
<SCRIPT stype=text/javascript> var xmlobj; //定义XMLHttpRequest对象 function CreateXMLHttpRequest() { if(window.ActiveXObject) //如果当前浏览器支持Active Xobject,则创建ActiveXObject对象 { //xmlobj = new ActiveXObject("Microsoft.XMLHTTP"); try { xmlobj = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { xmlobj = new ActiveXObject("Microsoft.XMLHTTP"); } catch (E) { xmlobj = false; } } } else if(window.XMLHttpRequest) //如果当前浏览器支持XMLHttp Request,则创建XMLHttpRequest对象 { xmlobj = new XMLHttpRequest(); } } function SubmitArticle(act,cityname,antique) //主程序函数 { CreateXMLHttpRequest(); //创建对象 //var parm = "act=firstweather" ;//构造URL参数 //antique = escape(antique); var parm = "act=" + act + "&cityname=" + cityname + "&antique=" + antique;//构造URL参数 //xmlobj.open("POST", "{dede:global.cfg_templeturl/}/../include/weather.php", true); //调用weather.php xmlobj.open("POST", "/weather/include/weather.php", true); //调用weather.php xmlobj.setRequestHeader("cache-control","no-cache"); xmlobj.setRequestHeader("contentType","text/html;charset=uft-8") //指定发送的编码 xmlobj.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;"); //设置请求头信息 xmlobj.onreadystatechange = StatHandler; //判断URL调用的状态值并处理 xmlobj.send(parm); //设置为发送给服务器数据 }
The second way is to submit a post request in the form of a virtual form
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; }
