的OnClick = QUOT; createComment（）;"不起作用 [英] OnClick="createComment();" doesn't work
问题描述
我是JS的新手。我按下定义为的按钮
I'm a newbie in JS. I'm pressing the button defined as
<input type="button" value="Create a Comment" OnClick="createComment();">
我的脚本功能是
function createComment() {
alert("1")
}
当按下按钮时，以下代码将无效，但当我将名称更改为somethingelse时，它可以正常工作
when pressing the button the following code won't work but when I change the names to somethingelse it works
<input type="button" value="Create a Comment" OnClick="somethingelse();">
function somethingelse() {
alert("1")
}
我多次检查过文档中没有使用任何createComment名称。我还注意到在jquery库中使用了createComment，但它似乎不是一个函数，但我不确定它是做什么的。
I've checked multiple times there isn't any createComment name used in the document. I also noticed createComment is used in jquery library but it doesn't seem like a function but I'm not sure what it does.

JQuery
// Check if getElementsByTagName("*") returns only elements
support.getElementsByTagName = assert(function( div ) {
div.appendChild( doc.createComment("") );
return !div.getElementsByTagName("*").length;
});
createComment名称有什么特别之处，还是jquery，为什么？
Is there something special with createComment name or is it jquery and why?
推荐答案
似乎 document.createComment 作为特殊功能存在 document object。它可能是保留的，因此您将无法将其用作函数名称。
It seems document.createComment exists as a special function for the document object. It's probably reserved, and thus you wouldn't be able to use it as a function name.
