如何在不使用jQuery但使用纯Javascript的情况下使用AJAX提交此表单

您可以通过以下方式提交表单

Ajax

function submitFormAjax() {    let xmlhttp= window.XMLHttpRequest ?        new XMLHttpRequest() : new ActiveXObject("Microsoft.XMLHTTP");    xmlhttp.onreadystatechange = function() {        if (this.readyState === 4 && this.status === 200) alert(this.responseText); // Here is the response    }    let name = document.getElementById('name').innerHTML;    let email = document.getElementById('email').innerHTML;    xmlhttp.open("GET","your_url.php?name=" + name + "&email=" + email, true);    xmlhttp.send();}

此示例正在使用

GET

POST

xmlhttp.open("POST","your_url.php",true);xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlenpred");xmlhttp.send("name=" + name + "&email=" + email);

注意：

完成

submitFormAjax()

validateFormOnSubmit

if (reason.length == 0) {    // Show some loading image and submit form    submitFormAjax();} else {    return false;}
