校验验证码
var btn = document.getElementById("btn");
btn.onclick = function () {
var mytxtVal = document.getElementById("mytxt").value;输入框中的验证码
var xhr = null;
try {
xhr = new XMLHttpRequest()
} catch (err) {
xhr = new ActiveXObject("Microsoft.XML")
}
调用open用get方式 把验证码传递给后台
xhr.open("get", "http://127.0.0.1:3000/VueHandler/AdminLoginAndRegHandler?action=checkVerification&veri=" + mytxtVal, true)
调用send
xhr.send()
等待数据返回
xhr.onreadystatechange = function () {
if (xhr.readyState == 4 && xhr.status == 200) {
console.log(JSON.parse(xhr.responseText))
}
}
}
