jQuery $(document).ready() not firing

问题

Using jQuery 1.4.2 from Google hosted Code.

Is there a reason why the following javascript does not fire all 3 document.ready functions when the document is ready?

The first $(document).ready() function, which renders headers, and the second, which gives a 'Foo' alert box triggered, but subsequent ones in new <script> blocks aren't triggered,

<script type="text/javascript">
    $(document).ready(function () {
        Cufon.replace('h1'); // Works without a selector engine
        Cufon.replace('h2'); // Works without a selector engine
        Cufon.replace('h3'); // Works without a selector engine
        Cufon.now();
    });
    $(document).ready(function () { alert("Number Foo"); });
</script>

// html tags

<script type="text/javascript">
    $(document).ready(function () { alert("Number One"); });
    $(document).ready(function () { alert("Number Two"); });
</script>

These are in seperate web parts, hosted on the same page in Sharepoint2010

回答1:

I can think of three forensic things to try, right off:

1. try it with non-google-hosted libraries.
2. comment out the Cufon calls -- I believe Cufon does some crazy stuff to download additional resources, yes? That may be interfering.
3. sub in $(window).load() for one or more of your $(document).ready() callback defs. They have different firing criteria -- $(window).load() waits for everything to load up, allegedly -- but the substitution may be revealing.

Of course, console.log() and alert() will be your in-leu-of-debugger-breakpoint best friends in this case.

回答2:

you're missing a closing curly bracket and parenthesis in the second script tag

回答3:

You are missing a }); in the end of the last $(document).ready

Once you correct this it should work

EDIT: Since you say now that each script tag is in a separate web part I believe the problem itself is not in the scripts. Something else in your page is messing up your code.
