Before I ask this question I must point out that I have tried to search for EVERYTHING!
My question is how can I run javascript from an external file instead of inside my php / html. What I'm trying to do is.
function ClearForm() {
document.form.message.value="";
}
function comeBack(){
if (document.form.message.value == "") {
document.form.message.value="What's on your mind?";
}
}
I have included<script type="text/javascript" src="javascript.js"></script> in the <head> and I have a file in the root called javascript.js and my php file is in the root too so that shouldn't be the problem! But how do I run that pieces of code you see above in the javascript.js file instead of in my php file. It work's fine if I have it in the php file but I want to separate things!
I have also tried to give the form / input field an id and then use getElementById in the external JavaScript file.
But as you can see and hear I'm kinda new to JavaScript so I'm apparently doing something wrong here.

If the above code is the only thing in your Javascript.js file, then you need to call the functions to run the code.
You've included the external Javascript file correctly - however, because all of your JS is included within functions, these function/s must be called before the code will run.
A call to 'ClearForm()' or 'comeBack()' from within your PHP file should run the code.
