问题描述
似乎是一个简单的初学者问题,但我无法在任何地方找到答案。
It seems like a simple beginners question, but I'm unable to find an answer anywhere.
假设我有这个HTML:
Let's say I have this HTML:
<form name="myForm">
<input type="text" name="myTxt">
</form>
然后我可以使用以下javascript
then I can use the following javascript
document.myForm.myTxt.value = 'foo';
但是如果我有一个div而不是一个表单呢?
But what if I have a div instead of a form?
<div name="myDiv">
<span name="mySpan"></span>
</div>
为什么我不能在这里做同样的事情,像
Why can't I do the same thing here, like
document.myDiv.mySpan.innerHTML = "bar";
似乎应该可以做,而不必使用getELementById(),但我可以
Seems like it should be possible to do, instead of having to use getELementById(), but I can't make it work.
推荐答案
由W3C设计。
真的没有什么可争论的。您可以通过 document.forms
访问页面上所有表单的HTMLCollection,就像您可以使用 document.images
applet与 document.applets
,链接与 document.links
和锚点与 document.anchors
。
There's really nothing to argue about. You can access the an HTMLCollection of all the forms on the page through document.forms
, much like you can images with document.images
, applets with document.applets
, links with document.links
and anchors with document.anchors
.
