How can I stop jQuery.ajax() from logging failures to the console?

The logging entry in chrome's console is a behaviour of chrome when any HTTP request is handled, not a problem with jQuery or ajax(XMLHttpRequest), even an <img> or <link> tag could cause this issue.

Your only choice is to fix your server-side code not to trigger an error for ajax (eg. 404 not found or wrong content-type), so based on the content logged to console, maybe a better solution could be found, please provide accurate logging message in your console.

put this in the top of your page:

<script>

$(document).ready(function() {
jQuery.migrateMute = true;
})
</script>

its temporary - but worked for me. Beats having to scroll through 45 lines of nonsense to debug js errors.
