您不能以这种方式将HTML嵌入Javascript。基本上，您想要的是嵌入一个脚本元素，单击按钮时指向某个javascript文件。可以通过将事件与DOM结合来完成：
<script type="application/javascript">function loadJS(file) { // DOM: Create the script element var jsElm = document.createElement("script"); // set the type attribute jsElm.type = "application/javascript"; // make the script element load file jsElm.src = file; // finally insert the element to the body element in order to load the script document.body.appendChild(jsElm);}</script><button onclick="loadJS('file1.js');">Load file1.js</button><button onclick="loadJS('file2.js');">Load file2.js</button>
