I give up, ive been at this for ages, what am I missing here? Im trying to set the action attribute of a form using javascript. It works when I use a string literal, it works when I use a variable declared in the same html file, it absolutely will not accept variables from another file... I dont understand why. Ive even dumped a copy of the ServerAPI.js file right there in the same directory to eliminate the possibility of it not being found.
HTML file, ive bolded the relevant bits:
ServerAPI.js, the file I want that first html document to be able to read variables from
What im doing works fine in index.html though:
Im certain ive missed something or theres something im not understanding about how this is meant to work
HTML file, ive bolded the relevant bits:
