18,416 Pointsif statement problem in Ajax
Hi, I am making a website where depending on what a column says in the database the javascript will perform a curtain task (using ajax). This is going fine, however in the if statement, when the requirements are met, it keeps repeating it since it's inside the setInterval. It is probably easier for me to just paste the code and give you a chance to take a look at it.
setInterval(function(){
$("#div").load("content.php");
if ($('#div:contains("hello")').length > 0) {
alert("Hello, world!");
}
}, 200);
As you can see above, the alert is alerted forever at the speed the interval is set to, please help.

56,403 PointsI think it would be best to first ask yourself when you when you want the if clause to run. Do you want it to run just once? Whenever the result changes? Then you'll have 2 conditions to check: does it contain "hello" and have I run this before/has the value changed from last time?
