Javascript 随机停止工作

Question

I can't get my Javascript to execute.It randomly stopped working yesterday and I've been messing around to try to get it to work. I tried making a simple code to see if it would work but, I have no luck. Here is the code:

HTML:

<script type="text/javascript" src="js\hello.js"></script>
<form id="hello" onsubmit="return hello();">
<input type="submit" />
</form>

Javascript (in sub folder called js):

function hello()
{
    alert("HELLO");
    return false;
}

It's really annoying me because all of my Javascript codes aren't working but they were working perfectly fine yesterday. I am not sure what happened...

I meant to make an alert I was just wasn't thinking. It still doesn't work anyways. It's like it isn't even calling the function.

Answer 1

use alert("HELLO"); instead of echo. echo is PHP not javascript.

If you want to output to a speicific tag then use document.getElementById("idOfTag").innerHTML = "HELLO";
