I have this written up for send a few variables to a php script:
$(function() {
$('a[class="removeUnread"]').click(function(){
var markedtopicid = $(this).attr("id");
var sessionvar = \'', $context['session_var'], '\';
var sessionid = \'', $context['session_id'], '\';
$.ajax({
url: "index.php?action=quickmod;board=', $context['current_board'], '",
type: "POST",
data: sessionvar + "=" + sessionid + "&topics[]=" + markedtopicid + "&qaction=markread",
});
});
});
I think this is the correct way to send post data via ajax, but it doesn't appear to be sending. Was I right to wrap the code in the ready function?
I can tell you right off the bat you should not have a semicolon between quickmod and board in your URL. I'm answering here because i cannot post comments yet. One good tool to use in web development ESPECIALLY with GET and POST requests is googles PostMan app. Its free to use and what it does is it will show you the exact output of any link you send it. So you can try putting the link that you make via javascript into postman and see what errors it spits out.
In this example i'm pretty sure your URL is all kinds of screwed up though. Try this instead...
"index.php?action=quickmod&?board="+$context['current_board']
fyi, i did not test that link so it may not work. If it doesnt work, google some ajax examples and javascript string concatenation. You're string is not suitable for ajax.
is should be like this...
$.ajax({
url :'index.php',
type : 'POST',
data : { sessionvar: sessionid, topics:markedtopicid},
success : function (data) {
},
error : function () {
}
Try handling the error:
$.ajax({
url: "index.php?action=quickmod;board=', $context['current_board'], '",
type: "POST",
data: sessionvar + "=" + sessionid + "&topics[]=" + markedtopicid + "&qaction=markread",
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.responseText);
}
});

I am trying to use jquery ajax to make a post request that returns some response but it does not seem to work properly. Sometimes it works after a long wait, other times it does not work at all.This is my code.
<script type="text/javascript">
const id = $('#auth').val();
$("#set").click(function(){
$('.spinner-grow').show();
$.post("https://ravesandboxapi.flutterwave.com/v2/gpx/transactions/escrow/settle",
{
id: id,
secret_key: "FLWSECK-25*******************0628-X"
},
function(data, status){
alert("Data: " + data + "\nStatus: " + status);
$('.spinner-grow').hide();
});
});
</script>
what might be the issue here?
The following is a complete example of a AJAX post is handled via jQuery. Just sharing it for reference.
var url = "api/path/to/your/controller";
var data = {};
data.id = id;
data.secret = 'your-secret';
$.ajax({
type: 'POST',
url: url,
data: data,
success: function (resultObject) {
console.log(resultObject);
},
error: function (err) {
console.log('An error occured');
}
});
If you are getting a 404 error, better check the path to the API. You can use a tool like Postman to validate your requests and then try implementing the same in code.
Also make sure that there is no CORS issue as from your code we cannot understand if your post is triggered from the same domain.
I am a beginner with JavaScript and I am facing some issues with parsing JSON and display the data I want to.
When I run the URL manualy in browser I get a correct result back.
The JavaScript code looks like this:
request = "URL"
function CallRestService(request, callback) {
$.ajax({
url: request,
dataType: "jsonp",
jsonp: "jsonp",
success: function (r) {
callback(r);
var results = data.resourceSets;
console.log(r.message);
alert(r.statusText);
},
error: function (e) {
alert("Error" + JSON.stringify(e));
console.log("Error" + e.message);
}
});
}
When I run this code I get no error in the console but I still get an alert via the error function: "status":200,"statusText":"OK"
Why do I get this?
And thats why I cannot get my data displayed, what I am doing wrong?
EDIT
so I was able to make a working code out of it, but I still get messages from SUCCESS and ERROR at the same time and I also get my data back?!
<script>
var request = "URL";
function CallRestService(request, callback) {
$.ajax({
url: request,
dataType: "jsonp",
jsonp: "jsonp",
success: function (r) {
callback(r);
console.log("working" + r.message);
alert(r.statusText);
},
error: function (e) {
alert("Error" + e.message + JSON.stringify(e));
console.log("message: " + e.message);
console.log("readyState: " + e.readyState);
console.log("responseText: "+ e.responseText);
console.log("status: " + e.status);
}
});
}
CallRestService(request, GeocodeCallback);
function GeocodeCallback(results) {
console.log(results.resourceSets[0].resources[0].travelDurationTraffic);
document.getElementById("sec").innerHTML=Math.round((parseFloat(results.resourceSets[0].resources[0].travelDurationTraffic) / 60));
}
</script>
Assuming that you put an actually URL into the request parameter this looks fine. A 200 status means it was successful and this likely called the console from your success function. I know you said you removed it to be sure, but the page could of been cached. If you take a look at the network request you will likely see that it was successful as well. Ifs possible that an error in your success function is occurring and triggering the error function. Have you tried adding break points inside of the two functions?
Here is a blog post that shows how to access the Bing Maps REST services using jQuery and other frameworks: https://blogs.bing.com/maps/2015/03/05/accessing-the-bing-maps-rest-services-from-various-javascript-frameworks/ It looks like your code is very similar.
I have a Java servlet, that i need to call and pass it a variable using Ajax. I have written an Ajax script, to get the variable that needs to be passed to the servlet. However i am not sure how to do so. Any help on this matter please?
This is my ajax code:
var data;
data = "NUMBER ='" + Number + "'";
var Key = '';
$.ajax({
type: "POST",
url: "Record?DB=EMP&Table=EMP_HISTORY&",
dataType: 'xml',
data: {
"Where": data
},
success: function(xml) {
$(xml).find('record').each(function() {
key = $(this).find("PK").text();
});
},
error: function(error) {
}
});
Your url parameter has & at last, I don't know if you have done it purposefully. However you may try this :
$.ajax({
url:"Record?DB=EMP&Table=EMP_HISTORY",
data:{Where:data},
contentType:"application/json; charset=utf-8",
dataType:"json",
success: function(xml) {
$(xml).find('record').each(function() {
key = $(this).find("PK").text();
});
},
error:function () {
}
});
It's unclear that which step u r in.Since that ,i would rather give u some advice.
1、if u dont use any webframework, then goto file web.xml and edit the servlet tag.configure the url and the according serlvet.Then u can overwrite the doPost() method in the servlet and receive the http request.
2、if u use webframework like struts.u can modify the configuration in struts.xml and write the according method in ur action to deal with the request.
3、if u use jsp as ur solution.u can simple do it in the jsp file. Deal with the request variables through getRequestParameter and out.print the result.
hope my advice is helpful!
I made an api in java , which allows the user to get data.
there is an call : ..../api/users where i give a list back of all users avalible.
Now i got a site with a search user button, wen you press that button i want to make a call to /api/users with the help of Ajax.
i got the part that you can click on the search button, but i don't understand how to make that call with ajax
This is my code:
$.ajax({
url: ”api / resource / users ",
dataType: "json”,
}
).fail(
funcNon(jqXHR, textStatus) {
alert("APIRequestfailed: " + textStatus);
}
).done(
funcNon(data) {
alert("succes!")
}
);
Is this the way of making a good call with ajax ?
or do i have to use :
http://localhost/projectUser/api/resource/users ?
Assuming you are using JQuery to make the Ajax call then this sample code should be helpful to you. What it does is;
On search button was clicked
Do AJAX call to fetch stuff from your Java REST API
When the expected JSON object was returned, parse it and do something
O
$(document).ready(function() {
$('#demoSearchBtn').click(function () {
// Search button was clicked!
$.ajax({
type: "GET",
url: "http://localhost/projectUser/api/resource/users", // edit this URL to point into the URL of your API
contentType: 'application/json; charset=utf-8',
dataType: "json",
success: function (data) {
var jsonObj = $.parseJSON(data);
// Do something with your JSON return object
},
error: function (xhr) {
alert('oops something went wrong! Error:' + JSON.stringify(xhr));
}
});
});
}
if this http://localhost/projectUser/api/resource/users is the url, it's either
$.ajax({
url: ”api/resource/users", ...
or
$.ajax({
url: ”http://localhost/projectUser/api/resource/users", ...
depending on what the browsers current URL is (relative or absoute depends on context of the browser).
but it is never ever ”api / resource / users " with spaces between words and slashes.
I have this function that performs a GET request for a given id:
var findById= function(id) {
console.log('findById: ' + id);
$.ajax({
type: 'GET',
url: rootURL + '/' + id,
dataType: "json",
success: function(data){
console.log('findById success: ' + data.name);
currentRaceEntry = data;
renderList(currentRaceEntry);
}
});
};
When I enter sitename/rest/entries/8 it returns a page with the xml for the object requested(as expected). (I can show this code but I dont think the problem is there). When I preform this request the console shows:
findById 8
My question is why doesn't it show console.log('findById success: ' + data.name);? The xml displays in the browser which looks to me like it was successful. So why doesn't the success function appear to be called? Thanks!
EDIT
this is what it looks like:
The console in the browser is blank
If you ajax request returns XML data, you need to set dataType as "xml".
At that point, the data object in the success function is an XML fragment, not a javascript objet, and you need to process it as such. The data.name property doesn't exist.
