Hi there is it possible to redirect to another page using ajax? I have this piece of code that I have been working on to try this.
<script type="text/javascript">
$(document.body).on('click', '#btnPrintPrev', function() {
$.ajax({
url: '/pdfdatacal',
data: {
dummydata: "This is a dummy data"
},
});
});
</script>
Now it should be able to carry data to another page and redirect there. Problem is it doesn't.
This is what I am using in my route
Route::get('/pdfdatacal', 'GenerateReportController#pdfdatacal');
Then in the controller
public function pdfdatacal(Request $request) {
return $request->data['dummydata'];
}
My expected result should be a blank page containing the value of dummydata but it doesn't do that in my code. How do I accomplish this?
first your ajax must be something like
$.ajax({
url: '/pdfdatacal',
method: 'post',
data: { dummydata: "This is a dummy data" },
dataType: "JSON",
success: function(response){
console.log(response); // just to check if the data is being passed
// do something you want if ever .
}
});
then in your routes
Route::post('/pdfdatacal', 'GenerateReportController#pdfdatacal');
in your controller
public function pdfdatacal(Request $request) {
return response()->json($request->dummydata);
}
hope it helps ..
Use
window.location.href = "http://yourwebsite.com/pdfdatacal";
In your success call
The idea is that you send data to your controller, it sends back a response, then you redirect from javascript to where you want.
$.ajax({
url: '/pdfdatacal',
type : 'GET',
data : {
dummydata: "This is a dummy data"
},
success : function(data) {
window.location.href = "http://yourwebsite.com/pdfdatacal";
}
});
But if your controller does nothing with the data you send, then you don't need to use ajax at all, simple redirect using javascript.
you could use window.location.assign('your URL here!'); in the success.
success : function(data) {
window.location.assign('your URL here!');
}

I am trying to get live validation on a register form that tells the user if the username they are trying has already been taken or not. I am using jQuery to detect change in the input and want to send the username they type as an AJAX to a Spring controller I have set up. Eventually it will plug it into a query and return if that username has already been registered. I am having trouble with the AJAX. Any ideas on how to accurately send the request?
My AJAX:
$(document).ready(() => {
function checkPassword() {
let usernameGiven = $("#username").val();
$.post( "/check",
{username: usernameGiven} ,
function(data) {
console.log(data)
})
}
$('#username').on('input', () => {
checkPassword()
});
});
My Controller:
#PostMapping("/check")
public String checkUsername(#RequestParam(name = "username") String username){
}
I haven't used jQuery in a long time but I don't think you can pass data with your post using that syntax. Try:
$.ajax({
type: "POST",
url: url,
data: data,
success: success,
dataType: dataType
});
dataType is the type of data you expect back from the server (xml, json, script, text, html).
While you're testing this, make sure you're actually returning some data back from your controller too, even if it's just mock data for now.
Maybe can work if you use:
<input id="username" onBlur="checkIfUserExist()">
Make a javascript function:
function checkIfUserExist() {
$.ajax({
url: "/check",
data:'username='+$("#username").val(),
type: "POST",
success:function(data){
console.log(data); //content user availability status
},
error:function (){}
});
}
}
Think I found what I was looking for. This is working for me. Let me know if you think there is a more efficient way of doing this.
#RestController
public class TestController {
#GetMapping("/getString")
public String getString(#RequestParam(name = "username") String username) {
return JSONObject.quote(username);
}
}
im passing a array data in my ajax to controller and use the data to the queries but when i already return the data it's blank when i alert it but in my network it have a data. Can someone help me about this?
routes:
Route::get('/member/page/press_release_email/view_send_email_press_release/sent_email', 'Member\Press_Release_Controller#pass_id');
ajax:
$.ajax({
type: "GET",
url: "/member/page/press_release_email/view_send_email_press_release/sent_email",
data: {ids:myArr},
dataType:"json",
success: function(data){
alert(data)
}
});
controller:
public function pass_id(Request $req)
{
$emails = Tbl_press_release_recipient::select('research_email_address')->whereIn('recipient_id', Request::input('ids'))->get();
return json_encode($emails);
}
You are trying to select research_email_address with their recipient_id but your ids are currently strings (As seen in your network's tab screenshot.)
You need to fill myArr with the recipient_id data.
I have the following code (jQuery) to create a json file:
$( ".save" ).on("click", function(){
var items=[];
$("tr.data").each(function() {
var item = {
item.Code : $(this).find('td:nth-child(1) span').html(),
itemQuantity : $(this).find('td:nth-child(4) span').html()
};
items.push(item);
});
});
Now this is my AJAX function:
(function() {
$.ajax({
url : "",
type: "POST",
data:{ //I need my items object, how do I send it to backend server (django)??
calltype:'save'},
dataType: "application/json", // datatype being sent
success : function(jsondata) {
//do something
},
error : function() {
//do something
}
});
}());
Now, my doubt is how do I send the 'item[]' object that I created to the backend? I do need to send both the item[] object and the variable 'calltype' which signals what made the AJAX call, as I have the same Django View (its the Controller equivalent for Django) in the backend being called by different AJAX functions.
How will my AJAX function look like?
Hey guys just got my answer right.
I used the following ajax function to get it right:
(function() {
$.ajax({
url : "",
type: "POST",
data:{ bill_details: items,
calltype: 'save',
'csrfmiddlewaretoken': csrf_token},
dataType: 'json',
// handle a successful response
success : function(jsondata) {
console.log(jsondata); // log the returned json to the console
alert(jsondata['name']);
},
// handle a non-successful response
error : function() {
console.log("Error"); // provide a bit more info about the error to the console
}
});
}());
So, this is sort of a self answer!!! :) Thanks a lot SO!!
I have written a simple code. In order to avoid flooding a JSON server, i want to break up the JSON response in pieces. So my jquery code should be parsing one variable ("page") to the php page that handles the JSON Oauth Request. On success, it should append the DIV with the latest responses.
My code should be working, except for the fact that my ajax post is not being received by my php file.
Here goes
archief.html
$("#klik").click(function() {
console.log("fire away");
page = page + 1;
$("#archief").load("trytocombinenewageandgettagsendates.php");
console.log(page);
$.ajax({
type: 'POST',
url: "trytocombinenewageandgettagsendates.php",
data: page,
success: function() {
console.log(page);
$.get("trytocombinenewageandgettagsendates.php", function(archief) {
$('#archief').append(archief);
});
},
error: function(err) {
alert(err.responseText);
}
});
return false;
});
The php file doesn't receive anything.
var_dump($_POST);
gives me array(0) { }.
Very strange, i'd really appreciate the help!
You are sending a string instead of key-value pairs. If you want to use $_POST you need to send key-value pairs:
...
$.ajax({
type: 'POST',
url: "trytocombinenewageandgettagsendates.php",
data: { 'page': page },
success: function() {
...
If you send a single value or string, you would need to read the raw input.
Also, you are sending 2 GET requests and 1 POST request to the same file. Is that intentional? Note that only the POST request will have the $_POST variable set.
Thank you for your help and not letting me post "this still doens't work" posts :)
I made the mistake of loading the "unConsulted" php file [$.get("trytocombinenewageandgettagsendates.php"] upon success. Instead, i append the response of the PHP.
The working code below:
$("#klik").click(function() {
console.log("fire away");
page = page + 1;
//$("#archief").load("trytocombinenewageandgettagsendates.php");
console.log(page);
$.ajax({
type: 'POST',
url: "trytocombinenewageandgettagsendates.php",
data: { 'page': page },
success: function(response){
$("#archief").append(response);
},
error: function(err) {
alert(err.responseText);
}
});
return false;
I want to to call a method GetAccount from my controller AccountController.cs, in my JavaScript factory LoginFactory.js. Something like this:
AccountController.cs:
public Account GetAccount(string userName)
{ ... }
LoginFactory.js:
if(x>y) {
var account = <%AccountController.GetAccount(someParam);%>
}
I've tried using [WebMethod] and Ajax, but I can't get it to work: I get a 404 response.
Assuming your GetAccount method can be reached at /Account/GetAccount when your application runs, you could use the following:
$.ajax({
type: 'GET',
url: '/Account/GetAccount',
data: { 'username' : 'a-username' },
dataType: 'json',
success: function(jsonData) {
alert(jsonData);
},
error: function() {
alert('error');
}
});
Note - this is dependant on jQuery.
This causes the browser to make a request to /Account/GetAccount as if you had done so by entering the URL in the URL bar, but of course, captures the returned json for use in your client side (javascript) script.
If this returns a 404, it would be worth checking your routing.
