This time I will bring you a detailed explanation of the steps for JS to obtain url parameters and send POST in json format. What are the precautions for JS to obtain url parameters and send POST in json format? The following is a practical case. Let’s take a look. one time.
<script type="text/javascript">
1. Get all parameter values of url
function US() {
var name, value;
var str = location.href;
var num = str.indexOf("?");
str = str.substr(num + 1);
var arr = str.split("&");
for (var i = 0; i < arr.length; i++) {
num = arr[i].indexOf("=");
if (num > 0) {
name = arr[i].substring(0, num);
value = arr[i].substr(num + 1);
this[name] = value;
}
}
}2. Use JS to send JSON format POST request
var us = new US();
var xhr = new XMLHttpRequest();
xhr.open("POST", "/searchguard/api/v1/auth/login", true);
xhr.setRequestHeader("Content-type", "application/json");
xhr.setRequestHeader("kbn-version", "5.3.0");
xhr.onreadystatechange = function() {
if (xhr.readyState == 4) {
if (xhr.status == 200) {
window.location.href = us.nextUrl;
}
}
};
xhr.send(JSON.stringify({
"username" : us.u,
"password" : us.p
}));
