Calling methods or functions with Jquery
So I can call a php page using jquery
$.ajax({ type: "GET", url: "refresh_news_image.php", data: "name=" + name,
success: function(html) { alert(html) $('div.imageHolder').html(html);
}
});
However this getting a bit messy, I have a few .php files that only really preform very simple tasks. If I 开发者_StackOverflow社区want to call a method
$images->refresh_image();
is this possible. Failing that I could just create a big file with lots of functions in it?
Thanks,

Well, depends on what the intention is, of course, but if you really only want to run the refresh_image function, you don't need to pass any data, you don't have to handle success etc, then this isn't messy:
$.ajax({
url: "refresh_news_image.php",
});
You could also create a general function, such as:
function php_func(name){
$.ajax({
data: { name: name }
url: "background_functions.php",
});
}
And then background_functions.php:
switch($_GET['name']){
case 'refresh_image':
$images->refresh_image();
break;
case 'something else':
something_else();
break;
}
In javascript, whenever you need it (perhaps on an onclick) then you'd simply invoke:
php_func('refresh_images');
Be careful not to use the GET-parameter to run whatever function is passed, as that's obviously a huge security risk. :-)
You cannot call php functions directly from jQuery because jQuery knows nothing about php. You could create a file that based on a given request parameter calls the respective function and returns the result.
