SCRIPT1014: Invalid character

Question

I have this script:

function slideSwitch() {
    var ae = jQuery('#featured-right a.active');
    if ( ae.length == 0 ) {
        ae = jQuery('#featured-right a:first');
        var i = jQuery('#featured-right a').index(ae);
        var bae = jQuery('#featured-left a.fb-'+i);
        bae.show();
    }

    var ne =  ae.next().length ? ae.next() : jQuery('#featured-right a:first');
}

$(document).ready(function(){
    var ae = jQuery('#featured-right a.active');
    if ( ae.length == 0 ) {
        ae = jQuery('#featured-right a:first');
        ae.addClass('active');
        var i = jQuery('#featured-right a').index(ae);
        jQuery('#featured-left a.fb-'+i).show();
        jQuery('#featured-right a:not(.active) span.key').hide();
    }
    setInterval("slideSwitch()", 1000);  
});

which works great on any browser but IE. On IE, IU get

SCRIPT1014: Invalid character featured.js, line 1 character 1

What is wrong here?

Answer 1

It seems that IE didn't like the fact that i was accessing the page without a HTTP server :) I was accessing c:\www\my-file. When accessing http://localhost/my-file .. worked great.

Answer 2

I had this same problem. It said there was an error in line 1 row 1 of the main file. I use a ton of AJAX in the page I was using.

It all boiled down to the fact that I had onclick="#" on an A tag. Once I removed that, the error went away.

I think when jQuery loads the html via an AJAX call, it takes the onclick tags and processes the javascript it finds inside.

Answer 3

Watch out for template string literals. This error was caused by a

`

character for me in IE11.

Answer 4

The problem is likely to be that the file is UTF-8 encoded and the file is being brought in via a script tag which doesn't define this encoding. If you add charset="UTF-8" as an attribute to the importing script tag hopefully that'll fix it.
