Complete JSON being outputed

The output consists of the complete JSON, which is:
{reply:"Login success"}
The expected output is only the value for the key 'reply' ,
Login success
The required code:
HTML
<div id="resp" style="color:red;"></div>
JS AJAX JQUERY
$.ajax({
url: 'tt.php',
method: 'POST',
data: {'pass': pass , 'uname':uname},
success: function(data) {
document.getElementById("resp").innerHTML = data;
}
});
PHP
$data['reply'] = "Login Success";
echo json_encode($data);
Solutions tried to print the necessary data
data[0]
data[1]
data[reply]
data.reply
data["reply"]

The PHP code you show us is not outputting what you say your expected output should be but, you can tell the AJAX call to expect JSON to be returned by adding dataType: 'JSON', to the properties of the call.
Then you can address the reply as data.reply
$.ajax({
url: 'tt.php',
method: 'POST',
dataType: 'JSON', // added this line
data: {'pass': pass , 'uname':uname},
success: function(data) {
// then you can address the reply like this
document.getElementById("resp").innerHTML = data.reply;
}
});

Call JSON inside AJAX success

I want to call a json data inside my AJAX success. I'm still new on manipulating json and AJAX. Can somebody help me on how to access my json data which is from another URL? And I want to compare the id to the JSON data. Here's my code so far:
function getCard(id){
$.ajax({
type: "GET",
data: "id=" + id,
success: function(data){
#call JSON data here from another URL
# Is it possible to call another AJAX here?
}
});
}

This code will work for you
$.ajax({
url: "url",
method: "post",
data: "id=" + id,
success:function(data) {
// success goes here
$.ajax({
url: "url",
async:false,
method: "post",
data: "id=" + id,
success:function(json) {
JSON.parse(json);
// compare data and json here
},
error: function(){
// error code goes here
}
});
},
error: function(){
// error code goes here
}
});

yes Zuma you can call another Ajax inside Success function of Ajax call. Below is the example:
$.ajax({
type: "post",
url: url1,
data: data1,
success: function(data){
$.ajax({
type: "post",
url: url2,
data: data2,
success: function(data){
});
});
});

function getCard(id){
$.ajax({
type: "Get",
url: "发送请求的地址",
data: "id=" + id,
success: function(data){
#call JSON data here from another URL
# if success,you can call another AJAX.
# Is it possible to call another AJAX here?
# yes!
}
});
}

Ajax post doesnt post "&" letter?

I successfully posy via ajax. However, I realized that it doesnt post "&". It also doesnt give any error. Here is my script
Html
<textarea id="aciklamatext">West & Union</textarea>
Ajax post
var aciklama = $('#aciklamatext').val();
$.ajax({
type: "POST",datatype:"json", async: false,
contentType: "application/x-www-form-urlencoded",
url: "/aciklama.php",
data: "aciklama=" + aciklama,
success: function(html){
}
});
aciklama.php
$aciklama = $_POST["aciklama"];
echo $aciklama;
Output
West

The easiest way to send data by ajax is to use JSON. Internal ajax converts the JSON data to a string and encodes all the special chars:
$.ajax({
type: "POST",
datatype:"json",
url: "/aciklama.php",
data: {"aciklama": + $('#aciklamatext').val()},
success: function(data){
}
});
One comment: The use of async false is deprecated. http://api.jquery.com/jquery.ajax/

Post data don't send using jQuery Ajax request

how to send large base64 data Array using jQuery Ajax. Here is my code :
$.ajax({
type: "POST",
url: "addPhoto.php",
data:{photosArray:photosArray},
dataType: "json",
success: function(data) {
$(data).each(function(){
...
});
}
});
photosArray contains between 3 and 12 very long strings like :
data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABQAAAAUCAMAAAC6V+0...
Is there any limit for POST data size in Ajax?

Open your php.ini file and find the line stating upload_max_filesize. The default it set to 2M, which is 2MB. Try increasing it to 3MB and see if you are still receiving the error.
And use
"cache": false

Is your data properly declared ? It can be either String, object or array. try following
$.ajax({
type: "POST",
url: "addPhoto.php",
data:"{photosArray:photosArray}",
dataType: "json",
success: function(data) {
$(data).each(function(){
...
});
}
});

Populate a html div with json data received from a server

I need to have a html div populated with the json data received from the server which is a json-rpc server and it retruns an application/jsson-rpc content type and i can see the result in the chrome and firefox dev tools... I need to view it as part of the page inside a given div
i have this script to populate the mybox div but it gives nothing
var returnedinfo;
var request = $.ajax ({
url: "/url",
type: "POST",
data: JSON.stringify(data),
success: function(json) {
alert("success sent ajax");
$("#mybox").html(json);
returnedinfo = json;
});
I also tied having the populating function outside the ajax block when the request is done
request.done(function(msg) {
$("#mybox").text(msg);
});
This just return an empty array like this
[object Object]
and nothing else help will be appreciated.

you need to append the key of the json item.
$("#mybox").html(json.key);

Add dataType to your ajax request.
var request = $.ajax ({
url: "/url",
type: "POST",
data: JSON.stringify(data),
dataType: "json",
success: function(json) {
alert("success sent ajax");
$("#mybox").html(json);
returnedinfo = json;
});

try this my working example
look contentType and html function to replace html of mybox element
$.ajax({
type: 'POST',
data: JSON.stringify(data),
contentType: "application/json; charset=utf-8",
url: 'url',
success: function (dataRes) {
$('#mybox').html(dataRes);
},
error: function(a,b,c) {
}
});
Note that in this case dataRes in success function is an html string like <strong>test</strong>. If your server side function returns a json object you should add dataType: 'json' to ajax request and then you can use properties of dataRes object like here $('#mybox').html(dataRes.property1);
