Question

I’m trying to match a certain script with the currently loaded scripts on the page:

if($('script[src="' + sn + '"]').length == 0)
  $('head').append('<scr' + 'ipt src="' + sn +'"></scr' + 'ipt>');  

This works but only for scripts that were loaded normally.

For scripts that were injected using javascript, like the one in my condition, it doesn’t work 🙁

Apparently scripts that are loaded this way are somehow invisible in the DOM, even though they run.

Answer 1

var isThere = false;
$("script").each(function() {
    if ($(this).attr("src") == sn) {
        isThere = true;  
        // this works also with injected scripts!!
    }
});
if (isThere === false) {
    $('head').append('<scr' + 'ipt src="' + sn +'"></scr' + 'ipt>');
}
