I am trying to understand the internal process of getScript. I am aware that it uses $.get method interally.I was thinking that jQuery puts a script tag reference into the DOM for being able execute that js file but I couldn't find script references of loaded scripts by getScript in the DOM .
So how does jQuery execute loaded scripts without script tag references in the DOM?
$.getScript('gallery.js')
is exactly same thing with $('<script src="gallery.js">').appendTo('body')
?
This is the interesting part in the source code.
jQuery seems to just receive the text and evaluates it in global scope:
converters: {
"text script": function( text ) {
jQuery.globalEval( text );
return text;
}
}
In case you load the script from a different domain, jQuery adds a new script
tag:
head.insertBefore( script, head.firstChild );
but removes it once the code was loaded:
// Remove the script
if ( head && script.parentNode ) {
head.removeChild( script );
}
