我应该在哪里把我的JavaScript code？ [英] Where should I put my JavaScript code?

问题描述

我想用code为自动完成。在code是这里。

I would like to use the code for the auto-complete. The code is here.

<script>
    $(function() {
        var availableTags = [
            "ActionScript",
            "AppleScript",
            "Asp",
            "BASIC",
            "C",
            "C++",
            "Clojure",
            "COBOL",
            "ColdFusion",
            "Erlang",
            "Fortran",
            "Groovy",
            "Haskell",
            "Java",
            "JavaScript",
            "Lisp",
            "Perl",
            "PHP",
            "Python",
            "Ruby",
            "Scala",
            "Scheme"
        ];
        $( "#tags" ).autocomplete({
            source: availableTags
        });
    });
    </script>



<div class="demo">

<div class="ui-widget">
    <label for="tags">Tags: </label>
    <input id="tags">
</div>

</div><!-- End demo -->



<div class="demo-description" style="display: none; ">
<p>The Autocomplete widgets provides suggestions while you type into the field. Here the suggestions are tags for programming languages, give "ja" (for Java or JavaScript) a try.</p>
<p>The datasource is a simple JavaScript array, provided to the widget using the source-option.</p>
</div><!-- End demo-description -->

不过，我想不通，我应该把这个code。在头？在身体？

However, I cannot figure out where I should put this code. In head? In body?

推荐答案

您或许应该把你的code就在body标签的结束。

You should probably put your code right at the end of the body tag.
