我能在<script>标签内嵌套另一个<script>标签吗？

7

这是我的代码。当屏幕宽度小于1025时，我正在尝试停止运行外部js文件。

<script type="text/javascript">
var gdsize = 1025;          
if(window.innerWidth>=gdsize) {

    <script>
    window.cookieconsent_options = {"message":"\"Geek Dashboard uses cookies to make sure you get the best experience on our website.\" -","dismiss":"It's OK","learnMore":"More Details Here","link":"http://www.geekdashboard.com/cookies/","theme":"dark-bottom"};
    }
    </script>


</script>

<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/cookieconsent2/1.0.9/cookieconsent.min.js"></script>

通常使用脚本标签（类型为text/javascript）将js嵌入标记中。标签本身不是有效的js，因此您不能嵌套脚本标签（除非在不透明上下文中，例如字符串）。 - Hunan Rostomyan

为什么要使用嵌套脚本来修改对象属性？

既然您已经在“脚本”中，可以通过更简单的方式解决：

<script type="text/javascript">
  var gdsize = 1025;          
  if(window.innerWidth>=gdsize) {

    window.cookieconsent_options = {"message":"\"Geek Dashboard uses cookies to make sure you get the best experience on our website.\" -","dismiss":"It's OK","learnMore":"More Details Here","link":"http://www.geekdashboard.com/cookies/","theme":"dark-bottom"};

  }    
</script>

我强制将SRC属性写入SCRIPT标签，类似的方式可以在SCRIPT标签中编写SCRIPT标签。这个脚本强制重新加载JS文件，每次加载页面时都会使用随机数版本号来防止缓存。它能够正常工作，成功加载JS文件：

    <div id="jsgenrandom"><script type="text/javascript"></script></div>
    
    <script type="text/javascript">
        var divjs = document.getElementById('jsgenrandom')
        var divjss = divjs.getElementsByTagName("SCRIPT")[0].src = "https://_route_/the_js.js?v="+ Math.floor(Math.random()*1000) + ""  
    </script>

使用JavaScript在SCRIPT标签内编写此解决方案。工作正常：

<div id="writeintoscript"><script type="text/javascript"></script></div>

<script type="text/javascript">
var writeintoscripts = document.getElementById('writeintoscript')
writeintoscripts.getElementsByTagName("SCRIPT")[0].innerHTML = "alert('WRITE INTO SCRIPT TAG WITH JAVASCRIPT')"
</script>

<script type="text/x-jQuery-tmpl">
    var gdsize = 1025;          
    if(window.innerWidth>=gdsize) {

    <script type="text/javascript">
        <!-- Some javascript here -->
        window.cookieconsent_options = {"message":"\"Geek Dashboard uses cookies to make sure you get the best experience on our website.\" -","dismiss":"It's OK","learnMore":"More Details Here","link":"http://www.geekdashboard.com/cookies/","theme":"dark-bottom"};
        }
    {{html "</sc"+"ript>"}}
</script>

您可以使用{{html "</sc"+"ript>"}}代替</script>

说明 [更新]:

当您在引号（字面）字符串中使用</script> HTML标记时，标记被视为闭合标记而不是字符串的一部分。因此，您不能直接在脚本部分中使用</script>标记。

一个解决方法是转义</script>标记并/或拆分<script>标记：

var scriptEnd = "</scr" + "ipt>";
document.write(scriptEnd);
