Hellp people...lets take a simple ajax code...
$.ajax({
method: "POST",
url: "some.php",
data: { name: "John", location: "Boston" }
})
.done(function( msg ) {
alert(msg.html());
});
I am Trying to fetch msg.html() after waiting for 5 seconds? so the process is as follows ...
send data to some.php
wait for 5 seconds
then return the html page data.
how can we achieve this?
Use setTimeout, The setTimeout() method calls a function or evaluates an expression after a specified number of milliseconds. The function is only executed once.
And if you want to fetch the html of msg then first of all make sure msg is a valid HTML string and before fetching the .html() please convert it to a jQuery object by $(msg).
$.ajax({
method: "POST",
url: "some.php",
data: {
name: "John",
location: "Boston"
}
})
.done(function(msg) {
setTimeout(function() {
alert($(msg).html());
}, 5 * 1000);
});
$.ajax({
type : 'POST',
url : 'some.php',
data :{ name : 'John', location : 'Boston'},
beforeSend : function(){
//you can do whatever you want here (loading gif etc.) until some.php responds
},
complete : fuction(){
//Here is for after responding
},
success : function(data){
//data is the response of some.php, you can use the data to fill some elements in DOM etc.
}
});
setTimeout(function(){
//the codes you write here fires after 5 secs
},5000);
and you can pass this where do you want.

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!');
}
POST localhost:5000/registrar
{
"enrollId": "jim",
"enrollSecret": "6avZQLwcUe9b"
}
How do I use this in a javascript file? Do I use JSON or JQuery? And how do I invoke the request function in .html?
Use jquery for this:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.0.0/jquery.min.js"></script>
And call function
$(document).ready(function(){
$.post('localhost:5000/registrar', {
"enrollId": "jim",
"enrollSecret": "6avZQLwcUe9b"
}, function(serverResponse){
//do what you want with server response
})
})
Same without shorthand to handle errors:
$.ajax({
type: "POST",
url: 'localhost:5000/registrar',
data: {
"enrollId": "jim",
"enrollSecret": "6avZQLwcUe9b"
},
success: function(){$('#register').html('<h1>Login successfull</h1>');},
error: function(){$('#register').html('<h1>Login error</h1>');},
dataType: dataType
});
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() {
$.ajax({
url : "",
type: "POST",
data:{ bill_details: items,
calltype: 'save',
'csrfmiddlewaretoken': csrf_token},
dataType: 'json',
// handle a successful response
success : function(jsondata) {
console.log(jsondata); // log the returned json to the console
alert(jsondata['name']);
},
// handle a non-successful response
error : function() {
console.log("Error"); // provide a bit more info about the error to the console
}
});
}());
So, this is sort of a self answer!!! :) Thanks a lot SO!!
I have following code to pull data from server. I want to call it on document.ready(). And I expect first request is made to server, get response and second request is made and so on.
But I see in Firebug, there are two request to server is being made at initial page load. I am not sure why two request.
Here is my code.
;var EVENTS = {};
;(function($) {
EVENTS.Collector = {
events: [],
getEventsData: function() {
var postData = {
'jsonrpc': '2.0',
'id': RPC.callid(),
'method': "events.getNewOrUpdated",
'params': {},
'auth': RPC.auth()
};
var events_request = $.ajax({
url: RPC.rpcurl(),
contentType: 'application/json-rpc',
type: "POST",
data: JSON.stringify(postData),
timeout: 30000
});
events_request.done(function(results) {
//console.log("Info " + results);
if (results.result.result !== null) {
if (EVENTS.Collector.events.length !== 0) {
alert(EVENTS.Collector.events.length);
} else {
alert(EVENTS.Collector.events.length);
}
}
});
events_request.fail(function(results) {
//console.error("Error " + results);
$("Error Message").insertAfter('.error');
});
events_request.always($.proxy(this.getEventsData, this));
}
};
})(jQuery);
EVENTS.Collector.getEventsData(); //function call
Thanks in advance
If you remove the code below does it call at all?
EVENTS.Collector.getEventsData(); //function call
By default ajax request are asynchronous. If you want each request to be kind of "blocking" until done, then proceed to next, you can send sync request just by adding async: false to ajax call parameters.
Give a try to the following snippet, if it's what you meant to do..??.
var events_request = $.ajax({
url: RPC.rpcurl(),
contentType: 'application/json-rpc',
type: "POST",
async: false,
data: JSON.stringify(postData),
timeout: 30000
});
Consider that sync requests causes the interpreter function pointer to wait till any result come back from the call, or till request timeout.
I want to send data to a java servlet for processing. The data will have a variable length and be in key/value pairs:
{ A1984 : 1, A9873 : 5, A1674 : 2, A8724 : 1, A3574 : 3, A1165 : 5 }
The data doesn't need to be formated this way, it is just how I have it now.
var saveData = $.ajax({
type: "POST",
url: "someaction.do?action=saveData",
data: myDataVar.toString(),
dataType: "text",
success: function(resultData){
alert("Save Complete");
}
});
saveData.error(function() { alert("Something went wrong"); });
The $.ajax() function works fine as I do get an alert for "Save Complete". My dilemna is on the servlet. How do I retrieve the data? I tried to use a HashMap like this...
HashMap hm = new HashMap();
hm.putAll(request.getParameterMap());
...but hm turns out to be null which I am guessing means the .getParameterMap() isn't finding the key/value pairs. Where am I going wrong or what am I missing?
You don't want a string, you really want a JS map of key value pairs. E.g., change:
data: myDataVar.toString(),
with:
var myKeyVals = { A1984 : 1, A9873 : 5, A1674 : 2, A8724 : 1, A3574 : 3, A1165 : 5 }
var saveData = $.ajax({
type: 'POST',
url: "someaction.do?action=saveData",
data: myKeyVals,
dataType: "text",
success: function(resultData) { alert("Save Complete") }
});
saveData.error(function() { alert("Something went wrong"); });
jQuery understands key value pairs like that, it does NOT understand a big string. It passes it simply as a string.
UPDATE: Code fixed.
Simple method to sending data using java script and ajex call.
First right your form like this
<form id="frm_details" method="post" name="frm_details">
<input id="email" name="email" placeholder="Your Email id" type="text" />
<button class="subscribe-box__btn" type="submit">Need Assistance</button>
</form>
javascript logic target on form id #frm_details after sumbit
$(function(){
$("#frm_details").on("submit", function(event) {
event.preventDefault();
var formData = {
'email': $('input[name=email]').val() //for get email
};
console.log(formData);
$.ajax({
url: "/tsmisc/api/subscribe-newsletter",
type: "post",
data: formData,
success: function(d) {
alert(d);
}
});
});
})
General
Request URL:https://test.abc
Request Method:POST
Status Code:200
Remote Address:13.76.33.57:443
From Data
email:abc#invalid.ts
you can use ajax post as :
$.ajax({
url: "url",
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: JSON.stringify({ name: 'value1', email: 'value2' }),
success: function (result) {
// when call is sucessfull
},
error: function (err) {
// check the err for error details
}
}); // ajax call closing
For the time being I am going a different route than I previous stated. I changed the way I am formatting the data to:
&A2168=1&A1837=5&A8472=1&A1987=2
On the server side I am using getParameterNames() to place all the keys into an Enumerator and then iterating over the Enumerator and placing the keys and values into a HashMap. It looks something like this:
Enumeration keys = request.getParameterNames();
HashMap map = new HashMap();
String key = null;
while(keys.hasMoreElements()){
key = keys.nextElement().toString();
map.put(key, request.getParameter(key));
}
To get the value from the servlet from POST command, you can follow the approach as explained on this post by using request.getParameter(key) format which will return the value you want.
