I wish to hide one ad on mobile version of my site. I want to do it this way.
<script>
if(screen.width > 900){
"here call the script that is ad"
}
</script>
my ad script is also js script but it is not on my domain so I can not use ajax call to call it. Any help is appreciated. my ad code looks like
<script src='//url..'> </script>
Why don't you just do that with css and media queries?
Wrap that add in a DIV (let's say <div id="ad_1">...[link to your ad or content]...</div>
) and add to your stylesheet
@media only screen and (max-width: 900px) {
#ad_1 { display: none; }
}
