Load PHP function with jQuery Ajax
- by brandon14_99
I have a file which is loaded at the top of my document, which is called Videos.php. Inside that file are several functions, such as getYoutubeVideos. On some pages, I need to call upon that function several times (up to 50), and it of course creates major lag on load times. So I have been trying to figure out how to call that function in, only when it is need (when someone clicks the show videos button). I have very little experience with jQuery's ajax abilities. I would like the ajax call to be made inside of something like this:
jQuery('a[rel=VideoPreview1).click(function(){
jQuery ("a[rel=VideoPreview1]").hide();
jQuery ("a[rel=HideVideoPreview1]").show();
jQuery ("#VideoPreview1").show();
//AJAX STUFF HERE
preventDefault();
});
Ok I have created this based on the responses, but it is still not working:
jQuery Code:
jQuery(document).ready(function(){
jQuery("a[rel=VideoPreview5]").click(function(){
jQuery("a[rel=VideoPreview5]").hide();
jQuery("a[rel=HideVideoPreview5]").show();
jQuery.post("/Classes/Video.php", {action: "getYoutubeVideos",
artist: "Train", track: "Hey, Soul Sister"},
function(data){
jQuery("#VideoPreview5").html(data);
}, 'json');
jQuery("#VideoPreview5").show();
preventDefault();
});
jQuery("a[rel=HideVideoPreview5]").click(function(){
jQuery("a[rel=VideoPreview5]").show();
jQuery("a[rel=HideVideoPreview5]").hide();
jQuery("#VideoPreview5").hide();
preventDefault();
});
});
And the PHP code:
$Action = isset($_POST['action']);
$Artist = isset($_POST['artist']);
$Track = isset($_POST['track']);
if($Action == 'getYoutubeVideos')
{
echo 'where are the videos';
echo json_encode(getYoutubeVideos($Artist.' '.$Track, 1, 5, 'relevance'));
}
