A button click triggers an ajax request. When the user clicks the button a second time while the first request is still loading, i want to override the first request\'s success
You can try the following hack, I have tested it with asynch setTimeout (instead of asynch jQuery.ajax) and it works -
var mySuccessHander = function() {
console.debug('Initial function');
}
var test = jQuery.ajax({
url: '...',
success: function() {
mySuccessHander();
}
});
And when the button is clicked for the second time, execute following -
mySuccessHander = function() {
console.debug('Overridden function');
}
You can set the ajax arguments to a variable first so you can modify it later on.
var clicks = 0,
ajaxArgs = {
url: '...',
success: function () {
console.debug('do something');
}
};
$('#myButton').click(function() {
++clicks;
if (clicks > 1) {
// set the success function if clicked more than once
ajaxArgs.success = function () {
console.debug('Success function ' + clicks);
}
}
$.ajax(ajaxArgs);
});
If you want to modify the success function only when ajax is still loading you can do this:
var loading = false,
ajaxArgs = {
url: '...',
success: function () {
console.debug('do something');
}, complete: function () {
loading = false;
}
};
$('#myButton').click(function() {
if (loading) {
// set the success function if ajax is still loading
ajaxArgs.success = function () {
console.debug('Another Success function ');
}
} else {
loading = true;
$.ajax(ajaxArgs);
}
});
Nice question , this will work..
var isRequestDone = true;
jQuery('#mybutton').click(function () {
var requestParams = {
url: '....',
beforeSend: function () {
isRequestDone = false;
},
success: function () {
isRequestDone = true;
console.debug('do something');
},
error: function () {
isRequestDone = true;
}
}
if (!isRequestDone) {
requestParams.success = function () {
console.log('please wait for a while!');
};
}
jQuery.ajax(requestParams);
});
beforeSend
will fire just before the request will go to server , so when request in on the server isRequestDone
will be false and hence will change success handler . on success callback from the first request it will again back to original.
