在下面的片段中,一切都按预期工作,但是当我点击“显示源代码”时,Firefox 产生了这个错误:

--[11:07:30.630] TypeError: document.getElementbyId is not a function @ http://localhost:8888/html5/native-rich-text.html:10

And Safari produces a similar error. What is causing this?

function showSource() {
var content = document.getElementbyId("edit").innerHTML
content.replace(/</g, '&lt;');
content.replace(/>/, '&gt: ');
prompt("Your Code:", content);

}

function createLink() {
var url = prompt("Enter URL:", "http://");
if (url)
document.execCommand("createlink", false, url);
}
<h1>Native Rich Text</h1>
<p>No textboxes here, that's a &lt;div&gt; element!</p>
<div>
<input type="button" value="Bold" onclick="document.execCommand('bold', false, null);">
<input type="button" value="Italic" onclick="document.execCommand('italic', false, null);">
<input type="button" value="Underline" onclick="document.execCommand('underline', false, null);">
<input type="button" value="Add Link" onclick="createLink();">

<div id="edit" style="border:solid black; height: 300px; width: 400px;" contenteditable="true">
Hello!
