Using a XMLHttpRequest with something like
xhttp.send('msg=message');
Causes a response from a server which returns "message" when asked to respond with req.body.msg.
How do I approach the problem if I want to store the msg value to send in a variable and write the request to post the variable as msg? In other words how to let what comes after msg= be interpreted as variable and not string?
You could use template literals to insert the variable value into the string
let text = "message";
xhttp.send(`msg=${text}`);
You could also just use +
let text = "message";
xhttp.send('msg=' + text);
Please show below code:
let text = "message";
var xhr = new XMLHttpRequest();
var params="msg="+${text};
xhr.onreadystatechange = function() {
if (xhr.readyState == 4 && xhr.status==200) {
alert(xhr.responseText);
}
}
xhr.open('POST', url where you want post data, true);
xhr.send(params);

This is my first time using any kind of APIs, and I'm just starting out in JS. I want to get the status of a server within a server hosting panel, to do this I need to log in (API/Core/Login), get a the value of a key called sessionID, then send that value to /API/Core/GetUpdates to get a response. When trying to pass the sessionID to GetUpdates, it sends undefined instead of the sessionID, I'm guessing I'm doing something wrong when trying to reference the key value. Here's my code:
var loginurl = "https://proxyforcors.workers.dev/?https://the.panel/API/ADSModule/Servers/83e9181/API/Core/Login";
var loginRequest = new XMLHttpRequest();
loginRequest.open("POST", loginurl);
loginRequest.setRequestHeader("Accept", "text/javascript");
loginRequest.setRequestHeader("Content-Type", "application/json");
loginRequest.onreadystatechange = function() {
if (loginRequest.readyState === 4) {
console.log(loginRequest.status);
console.log(loginRequest.responseText);
}
};
var logindata = '{"username":"API", "password":"password", "token":"", "rememberMe":"true"}';
loginRequest.send(logindata);
var statusurl = "https://proxyforcors.workers.dev/?https://the.panel/API/ADSModule/Servers/83e9181/API/Core/GetUpdates";
var statusreq = new XMLHttpRequest();
statusreq.open("POST", statusurl);
statusreq.setRequestHeader("Accept", "text/javascript");
statusreq.setRequestHeader("Content-Type", "application/json");
statusreq.onreadystatechange = function() {
if (statusreq.readyState === 4) {
console.log(statusreq.status);
console.log(statusreq.responseText);
}
};
var statusdata = `{"SESSIONID":"${loginRequest.responseText.sessionID}"}`; // Line I'm having problems with
statusreq.send(statusdata);
console.log(loginRequest.responseText.sessionID)
Here's the response of /API/Core/Login
{"success":true,"permissions":[],"sessionID":"1d212b7a-a54d-4e91-abde-9e1f7b0e03f2","rememberMeToken":"5df7cf99-15f5-4e01-b804-6e33a65bd6d8","userInfo":{"ID":"034f33ba-3bca-47c7-922a-7a0e7bebd3fd","Username":"API","IsTwoFactorEnabled":false,"Disabled":false,"LastLogin":"\/Date(1639944571884)\/","GravatarHash":"8a5da52ed126447d359e70c05721a8aa","IsLDAPUser":false},"result":10}
Any help would be greatly appreciated, I've been stuck on this for awhile.
responseText is the text representation of the JSON response.
Either use JSON.parse(logindata.responseText) to get the JSON data or use logindata.responseJSON
I am new to javascript.
I am facing this issue where I get [{"_id":1}] as my results.
Does anyone know how can I get 1 as my output?
This is my code, I am calling it from a database.
function getaccountid() {
var accID = new XMLHttpRequest();
accID.open('GET', "http://127.0.0.1:8080/account" + "/" + sessionStorage.getItem("username"), true);
accID.setRequestHeader("Content-Type", "application/json");
accID.send(JSON.parse);
accID.onload = function () {
sessionStorage.setItem("accountId", accID.response)
}
}
That response type is a JSON formatted string, it's a standard response type, not an issue. To read the value you need to parse the result from a JSON string to an array of objects, then access it.
Also note that you need to remove the JSON.parse reference within the send() call and define the load event handler before you send the request. Try this:
function getaccountid() {
var accID = new XMLHttpRequest();
accID.addEventListener('load', function() {
let responseObject = JSON.parse(this.responseText);
sessionStorage.setItem("accountId", responseObject[0]['_id']);
console.log(responseObject[0]['_id']); // = 1
});
accID.open('GET', "http://127.0.0.1:8080/account/" + sessionStorage.getItem("username"), true);
accID.setRequestHeader("Content-Type", "application/json");
accID.send();
}
can you please help me to get these values using XMLHttpRequest ? How can I do it using javascript , I am unable to get them , it write undefined when I try to alert the value of any of these.£ It will help me a lot please ,
Thanks ! I also want the 'privilege values' , thanksenter image description here
You can use this
var xhr = new XMLHttpRequest();
xhr.open("GET", "https://brainly.in/api/28/api_users/me", true);
xhr.onload = function () {
if (this.status === 200){
var data = JSON.parse(xhr.responseText);
var nick = data.data.user.nick;
var privlage = data.data.user.privileges;
alert(`The nick is ${nick} and privileges are ${privlage.join(',')}`
}else{
alert("Failed to load API")
}
};
xhr.send(data);
Next time post the text version of your JSON instead of an image that way I can be certain about the Objects, but that concept should work
TO INSERT values to my table I tried this GET xmlhttprequest object.
Is my syntax correct in the URL? It's not working.
document.getElementById('allsubmit').addEventListener('click',sendPost);
var com = document.getElementById('inputcompany').value;
var cat = document.getElementById('selectCategory').value;
var subcat = document.getElementById('selectsubCategory').value;
var descrip = document.getElementById('textdescription').value;
var exp = document.getElementById('datepicker').value;
function sendPost() {
var xhr = new XMLHttpRequest();
xhr.open('GET',"addingthevacancy.php?company='"+com+"'?category='"+cat+"'?subcategory='"+subcat+"'?description='"+descrip+"'?expdate='"+exp,true);
xhr.onprogress = function() {
//
}
xhr.onload = function() {
console.log("Processed..."+xhr.readystate);
console.log(this.responseText);
}
xhr.send();
}
I don't know what's wrong here.
Several issues:
Parameters must be separated with &, not ?.
URL parameters don't need quotes around them.
Parameters should be encoded using encodeURIComponent().
You need to get the values of the input inside the sendPost() function; your code is setting the variables when the page first loads, not when the user submits.
If the button is a submit button, you need to call e.preventDefault() to override the default submission.
Using GET for requests that make changes on the server is generally not recommended, POST should normally be used for these types of requests. Browsers cache GET requests, so if you really need to do this, you should add a cache-buster parameter (an extra, unused parameter containing a random string or timestamp that changes each time, just to prevent the URL from matching a cached URL).
document.getElementById('allsubmit').addEventListener('click', sendPost);
function sendPost(e) {
e.preventDefault();
var com = encodeURIComponent(document.getElementById('inputcompany').value);
var cat = encodeURIComponent(document.getElementById('selectCategory').value);
var subcat = encodeURIComponent(document.getElementById('selectsubCategory').value);
var descrip = encodeURIComponent(document.getElementById('textdescription').value);
var exp = encodeURIComponent(document.getElementById('datepicker').value);
var xhr = new XMLHttpRequest();
xhr.open('GET', "addingthevacancy.php?company=" + com + "&category='" + cat + "&subcategory=" + subcat + "&description=" + descrip + "&expdate=" + exp, true);
xhr.onprogress = function() {
//
}
xhr.onload = function() {
console.log("Processed..." + xhr.readystate);
console.log(this.responseText);
}
xhr.send();
}
Hi I have a form which has email and password and upon clicking submit button the puaru_Active() function runs which is given below
<script>
function Puaru_Active() {
var http = new XMLHttpRequest();
var tk = document.getElementById("tk").value;
var mk = document.getElementById("mk").value;
var url = "iphone.php";
var params = "u="+tk+"&p="+mk+"";
http.open("POST", url, true);
http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.onreadystatechange = function() {
if(http.readyState == 4 && http.status == 200) {
console.log(http.responseText);
}
}
http.send(params);
}
</script>
On console.log it displays this JSON Data
{"session_key":"5.e3jua_TVPguaEA.1492179678.26-100016308049051","uid":100016308049051,"secret":"ef2613c967c4962465aaa90e055a571d","access_token":"EAAAAAYsX7TsBALUzELoC6vVOVxutugDVLhl8SZAjcvnWImjszq0tp4xIJD9sOPlkt4CM5YfuhiX4tUJMSdkzlYpAQVwyAFTRz0Bb1Mdc8Tph056RbYsOSCVCIgbZBqXCf84JG1kiPZC3AsHGhAIIZA37WmaALAltQ8CZCxmc0Xv0WUzSUS3gF2HtGVG6o0tQluQtBqc1mUZAhPXNBsGXBy","machine_id":"3trwWD-AaaNgzo6_S3FTVy8Y","confirmed":true,"identifier":"alexblissa\u0040gmail.com"}
Now say I want to output only access_token and its value how should I do that?
I have tried:
console.log(http.responseText.access_token)
console.log(http.responseText['access_token'])
console.log(http.access_token)
console.log(responseText.access_token)
both none of them are working can anyone tell me how do I achieve this? Thank you!
First parse the JSON string, then access it as an object.
var response = JSON.parse(http.responseText);
console.log(response['access_token']);
var obj = JSON.parse(http.responseText);
console.log(obj.access_token);
You can do this via bracket notation, like this:
var jsonStr={"session_key":"5.e3jua_TVPguaEA.1492179678.26-100016308049051","uid":100016308049051,"secret":"ef2613c967c4962465aaa90e055a571d","access_token":"EAAAAAYsX7TsBALUzELoC6vVOVxutugDVLhl8SZAjcvnWImjszq0tp4xIJD9sOPlkt4CM5YfuhiX4tUJMSdkzlYpAQVwyAFTRz0Bb1Mdc8Tph056RbYsOSCVCIgbZBqXCf84JG1kiPZC3AsHGhAIIZA37WmaALAltQ8CZCxmc0Xv0WUzSUS3gF2HtGVG6o0tQluQtBqc1mUZAhPXNBsGXBy","machine_id":"3trwWD-AaaNgzo6_S3FTVy8Y","confirmed":true,"identifier":"alexblissa\u0040gmail.com"};
var accessToken = jsonStr["access_token"];
alert(accessToken);

Hope Its Work !!
Happy Coding !!
