Getting form data values in json format - json

How do you get the value of an html element attr for an ajax call?
my code:
$('#manager_pass').submit(function(evt){
evt.preventDefault();
$.ajax({
url: App.managerpassURL,
data: {
????????????
},
dataType: 'json',
type: 'POST',
success: function(r){
box_2.animate({'top':'-250px'},500,function(){
overlay.fadeOut('fast');
$('.action_wrapper').fadeOut(1000, function(){
$('.form').fadeIn(1000);
});
});
}
});
});
I need to get the value from here
<input type="text" name="managerPassword" value="" class="man_code">
Thanks

Something like this if you want to send JSON:
JSON.stringify({ "pass" : $('input[name="managerPassword"]').val() })
Of course make sure its secured if you want to send a password!

If you specify an id attribute on your input element, you can do the following to get the value in js:
document.getElementById('exampleid').value

$('#manager_pass').submit(function(evt){
evt.preventDefault();
var passtxt=$('input:text[name=managerPassword]').val();
$.ajax({
url: App.managerpassURL,
data: {
passtxt:passtxt
},
dataType: 'json',
type: 'POST',
success: function(r){
box_2.animate({'top':'-250px'},500,function(){
overlay.fadeOut('fast');
$('.action_wrapper').fadeOut(1000, function(){
$('.form').fadeIn(1000);
});
});
}
});
});

Display Json data with ajax in codeignitor 4

My JSON data is available in browser console. But i cannot display data in template.
<script type="text/javascript">
$(document).ready(function () {
$.ajax({
url: '<?php echo_uri("clients/session_details") ?>',
type: 'GET',
dataType: 'json',
success: function(response) {
var data = JSON.parse(response);
$("#result").html(data[0].rx-byte);
}
});
});
</script>
Based on the JSON data you provided, it seems like you are trying to display the rx-byte value in the HTML template. Here's a code sample that will do that:
$(document).ready(function () {
$.ajax({
url: '<?php echo_uri("clients/session_details") ?>',
type: 'GET',
dataType: 'json',
success: function (response) {
$("#result").html(response[0]["rx-byte"]);
}
});
});

AJAX success function not being called even though HTTP 200 is returned

When a user clicks 'buy now', I want the transaction to happen and the div to eventually be faded out and removed once being processed by the controller. Everything in the controller works as it should, but when I put the function in the success, it isn't called. However it works when the function is placed outside the success. Additionally, a window.alert() somehow works when there's a success.
Here is my script, everything works in regards to the controller etc
$(document).ready(function(){
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$('form.buy-product-form').on('submit', (function (e) {
e.preventDefault();
var product_id = $(this).attr("id");
$.ajax({
url: $(this).attr('action'),
type: 'POST',
data: {'id': product_id},
dataType: 'json',
success: function () {
window.alert("THIS ALERT COMMAND WORKS BUT THE FUNCTION DOESN'T!");
$(this).closest('.product').fadeOut("normal", function() {
$(this).closest('.product').remove();
});
}
});
}));
});
Everything above in the controller works fine as well, here is what it returns:
return response()->json(['ok' => 'ok']);
You cannot use this under success function because this is out scope . Just change your code like below :
$('form.buy-product-form').on('submit', (function (e) {
e.preventDefault();
var product_id = $(this).attr("id");
var element=this;//getting current element click in variable
$.ajax({
url: $(this).attr('action'),
type: 'POST',
data: {'id': product_id},
dataType: 'json',
success: function () {
window.alert("THIS ALERT COMMAND WORKS BUT THE FUNCTION DOESN'T!");
//passing variable
$(element).closest('.product').fadeOut("normal", function() {
$(element).closest('.product').remove();
});
}
});
}));

HTTP GET not getting

Trying this but getting nothig
function getWeather() {
$.ajax({
type: "GET",
url: "http://api.openweathermap.org/data/2.5/weather?q=London",
async: false,
jsonpCallback: 'jsonCallback',
contentType: "application/json",
dataType: 'JSON',
success: function(data)
{
$('#jsonp-results').html(JSON.stringify(data));
},
error: function(e)
{
alert(e.message);
}
});
return data; //The JSON response whould be in this so that I can take this and can do some operation
}
On clicking button it should return the JSON
<body>
<button onclick="getWeather();">Get Weather</button>
</body>
Expected example JSON:
{"coord":{"lon":-0.13,"lat":51.51},"sys":{"type":1,"id":5168,"message":0.0287,"country":"GB","sunrise":1415603442,"sunset":1415636293},"weather":[{"id":803,"main":"Clouds","description":"broken clouds","icon":"04d"}],"base":"cmc stations","main":{"temp":284.99,"pressure":1003,"humidity":76,"temp_min":283.75,"temp_max":286.15},"wind":{"speed":5.1,"deg":210},"clouds":{"all":75},"dt":1415624678,"id":2643743,"name":"London","cod":200}
I am not getting the mistake I have done.
EDIT
Tried with this from snippets given here:
<!DOCTYPE html>
<html>
<body>
<p id="temp"></p>
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script language="javascript" type="text/javascript">
function getWeather() {
data_Json = {};
$.ajax({
url: "http://api.openweathermap.org/data/2.5/weather?q=London",
dataType: 'JSON',
success: function(data) {
//alert(JSON.stringify(data));
data_Json = data;
//alert("Weather Report: "+data_Json);
},
error: function(e) {
alert(e.message);
}
});
return data_Json;
}
function temp() {
//getWeather();
var obj = JSON.stringify(getWeather());
//alert("Got"+JSON.stringify(obj));
//alert(JSON.stringify(getWeather()));
//document.getElementById("temp").innerHTML = obj.main.temp;
alert("Temp : "+obj);
}
</script>
</body>
<body>
<button onclick="getWeather();">Get Weather</button>
<button onclick="temp();">Temperature</button>
</body>
</html>
It returned {}
Not returned the JSON (the return defined in getWeather)
Not the temperature (in get element by id part)
Remove contentType from your request and it will work fine.
Since this is a cross origin request, you cannot set contentType.
Following is the error you will see in your console -
XMLHttpRequest cannot load http://api.openweathermap.org/data/2.5/weather?q=London. Request header field Content-Type is not allowed by Access-Control-Allow-Headers.
Also the statement return data; will fail as variable data is not available in that context.
You can use the below code for your purpose -
function getWeather() {
weatherJson = {};
$.ajax({
type: "GET",
url: "http://api.openweathermap.org/data/2.5/weather?q=London",
async: false,
jsonpCallback: 'jsonCallback',
dataType: 'JSON',
success: function(data) {
$('#jsonp-results').html(JSON.stringify(data));
weatherJson = data;
},
error: function(e) {
alert(e.message);
}
});
return weatherJson;
}
You can try this solution
function getWeather() {
data_Json = {};
$.ajax({
type: "GET",
url: "http://api.openweathermap.org/data/2.5/weather?q=London",
async: false,
dataType: 'JSONP',
success: function(data) {
$('#jsonp-results').html(JSON.stringify(data));
data_Json = data;
},
error: function(e) {
alert(e.message);
}
});
return data_Json; }
For Edit Part:-
<!DOCTYPE html>
<html>
<body>
<p id="temp"></p>
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script type="text/javascript">
function getWeather() {
data_Json = {};
$.ajax({
url: "http://api.openweathermap.org/data/2.5/weather?q=London",
dataType: 'JSON',
success: function (data) {
data_Json = JSON.stringify(data);
},
error: function (e) {
alert(e.message);
}
});
alert(data_Json);
return data_Json;
}
function temp() {
var obj = getWeather();
alert("Temp : " +obj);
}
</script>
<button onclick="getWeather();">Get Weather</button>
<button onclick="temp();">Temperature</button>
</body>
Hi See this,
function getWeather() {
var returnData="";
$.ajax({
type: "GET",
url: "http://api.openweathermap.org/data/2.5/weather?q=London",
async: false,
jsonpCallback: 'jsonCallback',
contentType: "application/json",
dataType: 'JSON',
success: function(data)
{
$('#jsonp-results').html(JSON.stringify(data));
returnData=data;
},
error: function(e)
{
alert(e.message);
}
});
return data; //The JSON response whould be in this so that I can take this and can do some operation
}
Do you actually have an element with id="jsonp-results" in your html?
Some hints to simplify:
You don't need to specify a jsonp callback if you are not using jsonp
Synchronous calls are not nice because they block, you should avoid that and they aren't even supported for cross-domain calls (which your case is)
Simplified example:
function getWeather() {
$.ajax({
url: "http://api.openweathermap.org/data/2.5/weather?q=London",
dataType: 'JSON',
success: function(data) {
$('#jsonp-results').html(JSON.stringify(data));
},
error: function(e) {
alert(e.message);
}
});
}
<body>
<button onclick="getWeather();">Get Weather</button>
<div id="jsonp-results"></div>
</body>
After your comment: It certainly works:

You must have something wrong in your setup.

JSON API to HTML

I try using different instructions to use a JSON API from a Wordpress-System in a HTML-Teamplate. Unfortunately I do not succeed. Does anyone have any idea how I can read the section "Content" of http://www.earnyour21.de/api/get_page/?id=1588?
blog: function () {
$.ajax({
url: 'http://www.earnyour21.de/api/get_page/?id=1588',
type: 'GET',
dataType: 'json',
success: function (data) {
console.log(data);
},
error: function (data) {
console.log(data);
}
});
}
If the data structure of the JSON will always be the same, you can simply access the object directly using the objects name in JS.
blog: function(){
$.ajax({
url: 'http://www.earnyour21.de/api/get_page/?id=1588',
type: 'GET',
dataType: 'json',
success: function(data){
$('#content_test').append(data['page']['content']);
},
error: function(data){
$('#content_test').append(data['page']['content']);
}
});
}
Basically you need to use jquery to grab the div with an id of content_test and then append your data from the json. http://api.jquery.com/append/ and http://www.json.com/ for further reference.

jQuery UI autocomplete pulling json from database

I am trying collect data from a database to in return populate the jQueryUI autocomplete field.
My ajax query that collects the data works fine as show below:
$.ajax({
type: "GET",
url: "/devices/autocomplete",
data: { keywords: keyword_string },
cache: true,
success: function(){
}
});
This returns data in an json format - I basically want to 'merge' this function with my autocomplete function but not sure what i'm doing wrong.
$("#tags").autocomplete({
source: function(request, response){
$.ajax({
type: "GET",
url: "/devices/autocomplete",
data: { keywords: keyword_string },
cache: true,
success: function(html){
//$("ul#results").html(html);
}
});
},
minLength: 2,
dataType: "json",
cache: false,
focus: function(event, ui) {
return false;
},
select: function(event, ui) {
this.value = ui.item.label;
/* Do something with user_id */
return false;
}
});
Can anyone explain how I pass the /devices/autocomplete URL to the autocomplete function & have this return the json data back to the autocomplete source?
provided the URL as explained by another user.
