I've done this a month before... But now its not working... The code is
window.onload = function(){
setTimeout(function(){
alert("Hello");
}, 10000);
};
This is written in script in head of the test.php page. The script and other tags are correct.
I would like to call a specific function every 10 seconds. The alert just shows once only. This is problem in every browser.... After this testing i would like to check the url every 2 seconds and call an AJAX function.
Any Help??
That's what setTimeout
does (executes once after a specified interval). You're looking for setInterval
(calls a function repeatedly, with a fixed time delay between each call to that function):
window.onload = function(){
setInterval(function(){
alert("Hello");
}, 10000);
};
请改用setInterval 。
var fn = function(){alert("Hello")};
It is possible using setTimeout:
window.onload = function(){ setTimeout( function(){ fn();window.onload() },10000) };
but the best solution is setInterval:
window.onload = function() { setInterval(fn,10000)};
setTimeout is intended for one-time run. Look at setInterval function.
