< script></script> JavaScript代码中的标签? [英] <script></script> tags inside of javascript code?

问题描述

我正在使用通过搜索网络找到的名为

I'm using a plugin that I found from searching the web called Apprise. It has worked well for what I have needed thus far. But, I want to apprise the facebook login plugin and to to that I need to following code:

<fb:login-button scope='email,publish_stream'>
Login
</fb:login-button>  

<script type='text/javascript' src='http://connect.facebook.net/en_US/all.js'></script>
<script>
window.fbAsyncInit = function() {
    FB.init({
        appId: '123456789',
        cookie: true,
        xfbml: true,
        oauth: true
    });
    FB.Event.subscribe('auth.login', function(response) {
        window.location = '/fb_redirect.php';
    });
    FB.Event.subscribe('auth.logout', function(response) {
        window.location.reload();
    });
    };
    (function() {
        var e = document.createElement('script'); e.async = true;
        e.src = document.location.protocol +
        '//connect.facebook.net/en_US/all.js';
        document.getElementById('fb-root').appendChild(e);
    }());

任何想要被告知的事情都可以通过放置

Anything that you want to be apprised can be done by putting

apprise();

在javascript中.但是，将<script></script>标记放在JS代码(apprise();)内会引起各种混乱，因为尚不清楚JS代码在何处结束.

in the javascript. However, putting the <script></script> tags inside of the JS code (apprise();) causes all sorts of confusion because it's not clear where the JS code ends.

有什么想法吗?

推荐答案

在<script>块和内联Javascript中均可使用的方法是\uxxxx，其中xxxx是十六进制字符代码.

The method that works in both <script> blocks and inline Javascript is \uxxxx, where xxxx is the hexadecimal character code.

• <-\u003c
• >-\u003e
• "-\u0022
• '-\u0027
• \-\u005c
• &-\u0026

• < - \u003c
• > - \u003e
• " - \u0022
• ' - \u0027
• \ - \u005c
• & - \u0026

演示:

HTML:

<div onClick="alert('Hello \u0022>')">click me</div>

<script>
    var s = 'Hello \u003c/script\u003e';
</script>
