I'm editing a friend's site using a CMS's WYSIWYG editor - in the HTML source (viewed by clicking a button like or something), I added a <script></script> tag with some JavaScript in. However, this JavaScript had a tiny error (I missed out a semi-colon or something) so it now has an error. When I try and load the WYSIWWG editor again, it doesn't show the toolbar with the Source Editor button anymore, as it was controlled by JS, and because there is a fatal JS error on the page, none of the JS works. So I can't access the HTML source now to correct my error.
I've tried to edit the HTML source in the Chrome Web Inspector to correct my error, but unlike with editing JS, you can't save HTML locally in the Web Inspector and then reload with your changes. Do you have any idea how I could fix this? All I need to be able to do is get the JS working and then I can go in, press the HTML source button in the Editor and correct my error permanently. Something else I thought of was correcting my error in the DOM Tree, and then reloading the JS via the Web Inspector console or something, and hopefully the toolbar would appear, now that the inline JS is correct.
