I have a form that when clicked the submit button makes a call via ajax. This ajax is inside a php file because I need to fill in some variables with data from the database. But I can not use the calls before / success. They just do not work, I've done tests trying to return some data, using alert, console.log and nothing happens. Interestingly, if the ajax is isolated within a file js they work. Some can help me please?
File:
<?php
$var = 'abc';
?>
<script type="text/javascript">
$(document).ready(function() {
$('#buy-button').click(function (e){
var abc = '<?php echo $var; ?>';
$.ajax({
type: 'POST',
data: $('#buy-form').serialize(),
url: './ajax/buy_form.php',
dataType: 'json',
before: function(data){
console.log('ok');
},
success: function(data){
},
});
});
});
</script>
HTML:
<form id="buy-form">
<div class="regular large gray">
<div class="content buy-form">
/* some code here */
<div class="item div-button">
<button id="buy-button" class="button anim" type="submit">Comprar</button>
</div>
</div>
</div>
</form>
---- EDIT ----
Problem solved! The error was in the before ajax. The correct term is beforeSend and not before. Thank you all for help.
You said it was a submit button and you do not cancel the default action so it will submit the form back. You need to stop that from happening.
$('#buy-button').click(function (e){
e.preventDefault();
/* rest of code */
Now to figure out why it is not calling success
$.ajax({
type: 'POST',
data: $('#buy-form').serialize(),
url: './ajax/buy_form.php',
dataType: 'json',
before: function(data){
console.log('ok');
},
success: function(data){
},
error : function() { console.log(arguments); } /* debug why */
});
});
My guess is what you are returning from the server is not valid JSON and it is throwing a parse error.
Try this
<script type="text/javascript">
$(document).ready(function() {
$('#buy-button').click(function (e){
e.preventDefault();
var abc = '<?php echo $var; ?>';
$.ajax({
type: 'POST',
data: $('#buy-form').serialize(),
url: './ajax/buy_form.php',
dataType: 'json',
beforeSend: function(data){
console.log('ok');
},
success:function(data){
}
});
});
});
And make sure that your php file return response
