<p>PHP is completely irrelevant for what you are doing. The generated HTML is what counts.</p>

<p>In your case, you are missing the <code>src</code> attribute. Use</p>

<pre><code> &lt;script type="text/javascript" src="file.js"&gt;&lt;/script&gt;
</code></pre>


blocks|key|870575|text|在这一点上，PHP输出的HTML与普通的HTML页面没有区别。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|870576|你绝对不应该做document.write。您的JS与PHP无关，因此第一个示例中一定存在其他错误(如文件路径)。|offset|length|style|CODE|870577|顺便说一句，在脚本中使用</script>会出现问题。HTML解析器在解析JS之前扫描JS时会看到结束脚本标记，因此会变得混乱。你会看到人们因为这个原因在做像'<'%2B'/script'这样的事情。|870578|编辑：|870579|正如T.J.Crowder所指出的，实际上您需要在<script>标记中将'href更改为src。哦，实际上Pekka在他的答案中指出了这一点，所以实际上在这里添加它完全是多余的。|870580|entityMap^0|0|7|E|0|C|9|27|D|0|0|P|8|11|5|19|3|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@$D|R|E|S|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|T|8|@$D|U|E|V|F|G]|$D|W|E|X|F|G]]|9|@]|A|$]]|$1|J|3|K|5|6|7|Y|8|@]|9|@]|A|$]]|$1|L|3|M|5|6|7|Z|8|@$D|10|E|11|F|G]|$D|12|E|13|F|G]|$D|14|E|15|F|G]]|9|@]|A|$]]|$1|N|3|-4|5|6|7|16|8|@]|9|@]|A|$]]]|O|$]]

<p>There is no difference between HTML output by PHP and a normal HTML page in this regard.</p>

<p>You should definitely not have to do the <code>document.write</code>. Your JS is not related to your PHP, so there must be some other error (like the file path) in the first example.</p>

<p>On a side note, you'll have problems using <code>&lt;/script&gt;</code> within a script. The HTML parser sees the closing script tag when scanning the JS before parsing it, and becomes confused. You see people doing things like <code>'&lt;'+'/script'</code> for this reason.</p>

<p>Edit:</p>

<p>As T.J. Crowder pointed out, actually you need to change <code>'href</code> to <code>src</code> in the <code>&lt;script&gt;</code> tag. Oops, actually Pekka pointed that out in his answer itself, so actually adding it here is totally superfluous.</p>


blocks|key|870590|text|在您的示例中，使用href属性来告诉您可以在哪里找到JavaScript文件。这应该是src属性：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|870591|?>+<script+type="text/javascript"+src="file.js"></script>+<?php|code-block|syntax|javascript|870592|有关详细信息，请参阅w3schools。|870593|entityMap|0|LINK|mutability|MUTABLE|url|http://www.w3schools.com/tags/tag_script.asp^0|9|4|17|3|0|0|A|9|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@$9|V|A|W|B|C]|$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|10|8|@]|D|@$9|11|A|12|1|13]]|E|$]]|$1|M|3|-4|5|6|7|14|8|@]|D|@]|E|$]]]|N|$O|$5|P|Q|R|E|$S|T]]]]

<p>In your example you use the <code>href</code> attribute to tell where the JavaScript file can be found. This should be the <code>src</code> attribute:</p>

<pre><code>?&gt; &lt;script type="text/javascript" src="file.js"&gt;&lt;/script&gt; &lt;?php
</code></pre>

blocks|key|1085454|text|从页面到file.js的路径更有可能是错误的。当你查看页面和view-source时，你看到了标签，它正在工作，现在是时候调试你的路径是否太相对了，也许你需要在它前面加一个/。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1085455|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

<p>Its more likely that the path to file.js from the page is what is wrong.
as long as when you view the page, and view-source you see the tag, its working, now its time to debug whether or not your path is too relative, maybe you need a / in front of it.</p>


blocks|key|1085489|text|我从来不喜欢关闭PHP块以将内容输出到浏览器，我更喜欢捕获输出，这样如果在我的逻辑中的某个点，我决定要更改输出(在输出已经发送之后)，我可以删除当前的缓冲区。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1085490|但是正如Pekka所说，你有问题的主要原因是你的javascript包含是因为你使用href来指定js文件的位置，因为你应该使用src。|offset|length|style|CODE|1085491|如果你有一个函数文件，里面有你的函数，那么添加如下内容：|1085492|function+js_link($src)

++++}
++++return+"";
}|code-block|syntax|javascript|1085493|代码中的n，无需使用?>关闭代码块，只需使用：|1085494|echo+js_link("jquery/1.6/main.js");|1085495|entityMap^0|0|16|4|1S|3|0|0|0|A|2|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|V|8|@$D|W|E|X|F|G]|$D|Y|E|Z|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|10|8|@]|9|@]|A|$]]|$1|J|3|K|5|L|7|11|8|@]|9|@]|A|$M|N]]|$1|O|3|P|5|6|7|12|8|@$D|13|E|14|F|G]]|9|@]|A|$]]|$1|Q|3|R|5|L|7|15|8|@]|9|@]|A|$M|N]]|$1|S|3|-4|5|6|7|16|8|@]|9|@]|A|$]]]|T|$]]

<p>I have never been a fan of closing blocks of PHP to output content to the browser, I prefer to have my output captured so if at some point within my logic I decide I want to change my output (after output has already been sent) I can just delete the current buffer.</p>

<p>But as Pekka said, the main reason you are having issues with your javascript inclusion is because your using <code>href</code> to specify the location of the js file where as you should be using <code>src</code>.</p>

<p>If you have a functions file with your functions inside then add something like:</p>

<pre><code>function js_link($src)
{
    if(file_exists("my/html/root/" . $src))
    {
        //we know it will exists within the HTTP Context
        return sprintf("&lt;script type=\"text/javascript\" src=\"%s\"&gt;&lt;/script&gt;",$src);
    }
    return "&lt;!-- Unable to load " . $src . "--&gt;";
}
</code></pre>

<p>The n in your code without the need for closing your blocks with <code>?&gt;</code> you can just use:</p>

<pre><code>echo js_link("jquery/1.6/main.js");
</code></pre>

<p>If you truly wish to use PHP, you could use</p>

<pre><code>include "file.php";
</code></pre>

<p>or</p>

<pre><code>require "file.php";
</code></pre>

<p>and then in file.php, use a heredoc &amp; echo it in.</p>

<pre><code>file.php contents:
$some_js_code &lt;&lt;&lt;_code
function myFunction()
{
   Alert("Some JS code would go here.");
}
_code;
</code></pre>

<p>At the top of your PHP file, bring in the file using either include or require
then in head (or body section) echo it in</p>

<pre><code>&lt;?php
require "file.php";
?&gt;
&lt;html&gt;
&lt;head&gt;
&lt;?php
echo $some_js_code;
?&gt;
&lt;/script&gt;

blocks|key|1085614|text|我找到了一个我喜欢的不同的解决方案：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1085615|<script>

<pre><code>&lt;script&gt;
    &lt;?php require_once(&quot;/path/to/file.js&quot;);?&gt;

<p>I have a problem with an js file in php.
if i include it like this:</p>

<pre><code>?&gt; &lt;script type="text/javascript" href="file.js"&gt;&lt;/script&gt; &lt;?php
</code></pre>

<p>the file isn't included and i get an error that the function isn't defined.</p>

<p>When i try it this way:</p>

<pre><code>&lt;script type="text/javascript"&gt;
document.write('&lt;script type="text/javascript" src="datetimepicker_css.js"&gt;&lt;/script&gt;');
&lt;/script&gt;
</code></pre>

<p>the first  tag in the document.write function closes <code>&lt;script type="text/javascript"&gt;</code></p>

<p>what is the correct way to do this?</p>

how to include js file in php?

我在php中有一个js文件的问题。如果我像这样包含它：?> <script type="text/javascript" href="file.js"></script> <?php该文件未包括在内，并且我得到一个错误，即该函数未定义。当我尝试这样做的时候：<script type="text/javascript">...
