jQuery的替换：$（&#39;＃id&#39;）。html（HTMLfragment）//含。 <script> execution

Question

HTMLfragment is a HTML fragment that contains <script> parts. Therefore

document.getElementById('id').innerHTML = HTMLfragment;

doesn't work (all browsers incl. Chrome). It works only for HTML fragments that don't have any <script> parts in it. So how can I assign a HTML fragment that has <script> parts in it to a DIV using Google Closure or — even better — plain JavaScript?

Update

My responseText...

<style>
    label, input {
        display: block;

    function hide(cmdName) {
        document.getElementById("edit-form-" + cmdName).style.display = "none";

...is what I get as my XHR2 responseText executing this snippet:

            var xhr = new XMLHttpRequest();
            xhr.open('GET', handlerMap[window.location.pathname], false);
            xhr.onload = function(e) {
                console.log(this.responseText);
//                $('#main').html(this.responseText);
                document.getElementById('main').innerHTML = this.responseText;
            };
            xhr.send();

The commented jQuery method works to assign the responseText content to the DIV element with the ID "main" but the regular JavaScript method doesn't. Using the document method, just the non-JavaScript part is applied (I can see the table & form) but the JavaScript part can't be executed.

So how can I assign responseText to the DIV element without using jQuery?

Answer 1

$('#id').append('<script type="text/javascript" src="http://somesite.com/somejs.js"></script>');

That would append the script to the end of the #id innerHTML. Pretty easy. Style would be the same thing.

You can also do:

var s = document.createElement("script");
s.type = "text/javascript";
s.innerHTML = "//write your js code here"+
              "//and here ";
document.getElementsByTagName("head")[0].appendChild(s);

That would allow you to do the same thing.

Answer 2

document.getElementById('question').innerHTML = '<style>* { color:red; }</style>'; 

works for me on SO for instance. can you show larger codesnippet that doesn't work? also in which browsers have you found it to malfunction ?
