Hi guys,
I am trying to use jQuery (latest version) & ajax to poll a mysql db every x seconds, post.php does a simple search query on the table and limits to 1 row. (eg SELECT id FROM TABLE LIMIT 1)
I've got some other jQuery UI (using v1.8) code that displays some modal/dialog boxes on the screen, simply put if post.php returns something from the db I need to initialise the dialog to pop up onto the screen. I've done all the popup stuff I am just having issues joining all these bits together - i've added some pseudo code of how i expect this to work. Thanks in advance
var refreshId = setInterval(function(){
$.ajax({
type: "POST",
url: "post.php",
data: "",
success: function(html){
$("#responsecontainer").html(html);
}
});
}, 2000 );s
/* proposed pseudocode */
if (ajax is successful & returns a db row to #responsecontainer) {
show jQueryUI modal (done this bit already fortunately)
}
