问题
I am using an external javascript file, which I am using to store all my javascript functions in. Next I am trying to call a function from the body, using the next line of code:
<body onload="imageRefreshBig()">
The only thing that this function does is making an alert box pop up, well that's what's it supposed to do. I know this is a rather easy question but I have been banging my head against a wall trying to find a problem/fix for this issue and nothing is working.
I also include the javascript file in my head:
<script type="text/javascript" src="javascript.js"></script>
But as you probably see this isn't working. Could anyone explain what is going wrong with my syntax/thinking. The only thing I could think of is that either my document is not being loaded properly or that I have a syntax error.
回答1:
You can try use in javascript:
window.onload = function() {
alert("let's go!");
}
Its a good practice separate javascript of html
回答2:
Try this one:
<body onload="imageRefreshBig();">
Also you might want to check Javascript console for errors (in Chrome it's under Shift + Ctrl + J).

There's nothing wrong with include file in head. It seems you forgot to add;. Please try this one:
<body onload="imageRefreshBig();">
But as per my knowledge semicolons are optional. You can try with ; but better debug code and see if chrome console gives any error.
I hope this helps.

You are missing the ()
<body onload="imageRefreshBig();">
