I am working on a Stock Exchange jQuery fix for a website.
EDIT: It updates a ID/CLASS or input value on the webpage depending on the value returned.
index.php:
<!doctype html>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<meta charset="utf-8">
<title>load demo</title>
<script type="text/javascript">
$(document).ready(function() {
$.ajax({
url: '/datacall/demo.json',
dataType: 'json',
success: function( resp ) {
$( '#div' ).val( resp.currency[0].amount );
},
error: function( req, status, err ) {
console.log( 'Something went wrong', status, err );
}
});
var end = parseInt($('#value').val());
var newend = parseInt($('#div').val());
var result = $( end * newend );
$('#clickme').click(function() {
$('#new').val( result );
});
});
</script>
<div>
<input type="hidden" value="2500" id="value" />
<input type="hidden" value="" id="div">
<input type="text" id="new" value="" readonly/>
<input type="button" value="Change" id="clickme" />
</div>
Currently it is returning:
[object Object]
I have also tried returning it to a div with .text()
demo.json:
{ "currency" : [
{
"name" : "South Africa",
"code" : "ZAR",
"amount" : 0.14
},
{
"name" : "America",
"code" : "USD",
"amount" : 0.64
},
{
"name" : "Europe",
"code" : "GBP",
"amount" : 1.29
}
] }
Please can someone tell me what I did wrong.
Thanks in advance!

You can do this:
// Create some global variables
var end = parseInt($('#value').val(), 10);
var newend = 0;
var result = 0;
$.ajax({
url: '/datacall/demo.json',
dataType: 'json',
success: function (resp) {
// Check the values in console
console.log(resp.currency[0].amount);
console.log(resp.d.currency[0].amount);
$('#div').val(resp.currency[0].amount);
newend = parseInt(resp.currency[0].amount, 10);
result = end * newend;
// No need to create a new jQuery object using $()
// result = $( end * newend );
},
error: function (req, status, err) {
console.log('Something went wrong', status, err);
}
});
$('#clickme').click(function () {
$('#new').val(result);
});
So the main issues here is:-
result logic in the ajax success callback, as ajax is asynchronous and you always get the empty values for the end & newend variables. result = $( end * newend ); as it creates a new jQuery object instance and hence you are getting [object Object]

[object Object] is basically an array
Try this code:
success: function( resp ) {
//$( '#div' ).val( resp.currency[0].amount );
alert(JSON.stringify(resp));
},
This should show you the array, which will give you the ability to better select the elements to output
