The following code is not working in IE8, I have to get data from my controller and need to access the function abcd() and do something, my breakpoint comes out directly without going inside the ajaxcall
$.ajax({
url: "/Transactions/MyList/" + transactionID,
type: "GET",
contentType: "application/json",
cache: false,
success: abcd
});
**function abcd()** {
//do something
}
$.get( "//here give the id/class" );
For example:
$.get( "test.php" );
or
$.get( "test.php", { name: "abc", time: "2pm" } ); etc
I would guess that MyList is an action method inside TransactionsController and it returns JsonResult. Correct? Do you AllowGet on your Json result? you can pass a second parameter to the Json result which indicates the AllowGet behaviour (return Json(data, JsonRequestBehavior.AllowGet))...
Plus your abcd method should have one parameter - data - to process what you receive from the call...

I have the following ajax link:
#Html.AjaxActionLink(item.Name, "https://test.testspace.space/storage/Data/stream?tokenValue=e58367c8-ec11-4c19-995a-f37ad236e0d2&fileId=2693&position=0", new AjaxOptions { HttpMethod = "POST" })
However, although it is set to POST, it seems that it still sends GET request.
UPDATE:
As suggested below, I also tried with js functuion like this:
function DownloadAsset() {
alert("downloading");
$.ajax({
type: "POST",
url: 'https://test.testspace.space/storage/Data/stream?tokenValue=add899c5-7851-4416-9b06-4587528a72db&fileId=2693&position=0',
success: function () {
}
});
}
However, it still seems to be GET request. Parameters must be passed as query and not in the body of the request because they are expected like that by the target action. I don't know why (it would be more natural to have GET request) but back-end developer designed it like this due to some security reason.
If I use razor form like this, then it works:
<html>
<form action="https://test.testspace.space/storage/Data/stream?tokenValue=2ec3d6d8-bb77-4c16-bb81-eab324e0d29a&fileId=2693&position=0" method="POST">
<div>
<button>Send my greetings</button>
</div>
</form>
</html>
However, I can not use this because I already have bigger outer form on the page and I'll end up with nested forms which is not allowed by razor/asp.
The only way is to use javascript but for some reason it does not make POST request.
#Html.AjaxActionLink will generate to <a> tag,and tag will only have HttpGet request method.If you want to send HttpPost with <a> tag,you can use it call a function with ajax,here is a demo:
link
<script>
function myFunction() {
$.ajax({
type: "POST",
url: "https://test.testspace.space/storage/Data/stream",
data: { tokenValue: "e58367c8-ec11-4c19-995a-f37ad236e0d2", fileId: "2693", position:0 },
success: function (data) {
}
});
</script>
Since you want to make a POST request, but the values need to be as query string params in the URL, you need to use jquery.Param.
see https://api.jquery.com/jquery.param/.
You should set the params, like below :
$.ajax({
url: 'your url',
type: 'POST',
data: jQuery.param({ tokenValue: "your token", fileId : "2693", position: 0}) ,
...
Try this instead,
First remove the action url from the from
Second put the result in the success function to return response
and for parameters, I always use FormData() interface to post with Ajax
And last don't forget to include dataType, contentType, processData to not get an unexpected behavior
your code will look like this
var form_data = new FormData();
form_data.append('tokenValue' ,'add899c5-7851-4416-9b06-4587528a72db&fileId=2693');
form_data.append('position' ,'position');
$.ajax({
type: "POST",
dataType: 'json',
contentType:false,
processData:false,
data: form_data,
url: 'https://test.testspace.space/storage/Data/stream',
success: function (result) {
}
});
I have a very basic ajax call to alert the data that was reported from the server
$.ajax({
type: "POST",
url: "/someform/act", //edit utl to url
data: { changed: JSON.stringify(plainData) }, //edit to include
success: function(data) {
alert(data); //data not $data
},
error: function() {
//error condition code
}
});
According to the docs on the jquery website regarding data field on the success callback, it says that data returned is the data from the server. However for some strange reason when I alert $data, I get [object Object]
I was expecting to see something like this, since that is what the server would send back
<status>0</status>
EDIT:
data is also passed along as the POST
You need to use JSON.stringify(data) in the alert to get anything readable.
Also, $data is a completely different variable name than data.
alert() prints the string representation of the arguments - hence if you pass an object, you'll get [object Object].
To inspect data, use console.log(data) better.
If you server send a JSON, you need to put dataType: 'json' to your ajax call. Be aware there's some mistake in your ajax call.
$.ajax({
type: "POST",
url: "/someform/act", // NOT 'UTL',
data: {
key: value,
key2: value2
},
// or data: plaindata, // If 'plaindata' is an object.
dataType: 'json',
success: function(data) {
console.log(data); // As moonwave99 said
},
error: function() {
//error condition code
}
});
EDIT
When sending data, you should send an object. jQuery will handle the array to sned it to the server. So if plain data is an object, it should be like this
data: plainData,
If you're sending data via $.ajax({...}), the Network tab of your browser inspector might be showing [object Object] in the Payload (Chrome) / Request (Firefox) sub-tab, like in the following image (Firefox):
The reason for this might be in the way you're forming your AJAX call. Specifically:
$.ajax({
url: '/ajax/example-endpoint',
data: {'fooKey':fooData,'barKey':barData},
type: 'post',
cache: false,
contentType: false, // this one will turn your data into something like fooKey=fooData&barKey=barData
processData: false, // and this one will make it [object Object]:""
beforeSend: function() {
// whatever it is you need to do
},
success: function(data) {
// do stuff
},
error: function(desc, err) {
// do stuff
}
});
When combined, contentType: false and processData: false turn your data into [object Object], because you're actually telling your AJAX call to ignore the content type of whatever is being sent, and not to process it.
If it's IIS, try creating a site outside of the Default Web Site (for example localhost/ajax1). For example a new site ajax1, place it not in the DefaultAppPool, but in your pool, for example ajax1. Try http://ajax1
var p = JSON.stringify(parameter);
console.log(p);
$.ajax({
type: 'POST',
url: 'http://abc.com/ajax.php',
data: p,
success: function(status) {
console.log(status);
}
});
console.log(p) shows {"o_fname":"hh","o_lname":"jkhk","o_email":"uifh#bjvh.com","o_phone":"","b_name":"bmnbmbm,b","b_address":"","b_city":"","b_postal":"","b_phone":""}
but in my http://abc.com/ajax.php page print_r($_POST) is giving me an empty array Array()
var p = JSON.stringify(parameter);
That is your problem.
When you pass string data to .ajax, it sends it “as-is” – but PHP only popuplates $_POST if it receives data encoded as application/x-www-form-urlencoded.
So don’t make your data into a string, but pass your parameter object directly as value for data – then jQuery will take care of sending it the right way, so that PHP understands what it is supposed to do with it.
I think park of the problem may be that in data: you're passing the parameter details, but to the function on the other side of the jQuery you're passing a parameter name and nothing else.
Try:
$.ajax({
type: 'POST',
url: 'http://abc.com/ajax.php',
data: {parametername:p},
success: function(status) {
console.log(status);
}
});
With parametername replaced with the parameter name ajax.php is expecting.
I have a ajax call which i need to call with some specific parameter attached to it such that there is parameter field in net section in firebug.
and the parameter is not a data but a type like type, = copy must be attached to the call
You want to use like this and pass data..
jQuery.ajax({
type: "POST",
url: "example.php",
data: { identityid:0,userid:"<?php echo $user_id;?>" },
success: function() {
}
});
I am trying to use the response from a jQuery ajax request to set the innerHTML of a div with a certain id. This is the code I am using:
$(".show_comments").click(function(){
var articleName = $(this).closest("article").find(".articlename").attr('id')
$.ajax({
url: "commentView.php",
data: { 'articleName': articleName },
cache: false,
dataType: "html", // so that it will auto parse it as html
success: function(response){
$(this).closest("article").find(".comments").html(response);
}
});
however it doesn't seem to be doing anything at all, I've tried googling around, but everything I can find says to do it the way I am doing it... I have tested in Firebug and the ajax request is giving me the exact response I want it too... But I just cant access this to set the innerHTML of the div to the response!
In your ajax success handler there is another scope and this points to not what you think. So change your code to:
var articleName = $(this).closest("article").find(".articlename").attr('id'),
that = this;
$.ajax({
url: "commentView.php",
data: { 'articleName': articleName },
cache: false,
dataType: "html", // so that it will auto parse it as html
success: function(response){
$(that).closest("article").find(".comments").html(response);
}
});
What I've changed: I added that variable that points to this instance and use it in the success handler instead.
How would you debug it yourself: if you tried to output console.log(this) and console.log($(this).closest("article").find(".comments")); you would see that it returns a wrong object (in first case) and nothing in second.
