不要！
id属性是应该是独一无二的。要在
上有重复的ID，同一页面实际上错误地使用了id-tag。
请参阅： http://www.w3.org/TR/html4/struct/global .html＃adef-id
如果你必须有相同的名字，请使用name属性。

Don''t!
The id attribute is supposed to be unique. To have duplicate id''s on
the same page is actually wrong use of the id-tag.
see: http://www.w3.org/TR/html4/struct/global.html#adef-id
Use the name attribute if you must have equal names.

不，没有。正如Dag所说，使用相同的ID是无效的HTML，所以
浏览器行为可能无法预测。

No, there isn''t. As Dag said, using the same ID is invalid HTML and so
browser behaviour can be unpredictable.

你必须改变它们。一旦你这样做，你可以使用类似的东西：
< div id =" myID1">& nbsp;< / div>
< div id =" myID2">& nbsp;< / div>
var getRefById = function（）{return null;};
if（document.getElementById）{
getRefById = function（i）{return document.getElementById（i）;};
} else if（document.all） {
getRefById = function（i）{return document.all [i] || null;};
}
函数changeContents（）{
var o，nD = 2; // DIV的数量
for（var i = 1; i< = nD; ++ i）{
o = getRefById（''myID' '+ i）;
if（o）{o.innerHTML =''Hello'';}
}
}
[snip]
如果你必须有相同的名字，请使用name属性。
You''ll have to alter them. Once you do, you can use something like:
<div id="myID1"> </div>
<div id="myID2"> </div>
var getRefById = function() {return null;};
if(document.getElementById) {
getRefById = function(i) {return document.getElementById(i);};
} else if(document.all) {
getRefById = function(i) {return document.all[i] || null;};
}
function changeContents() {
var o, nD = 2; // Number of DIVs
for(var i = 1; i <= nD; ++i) {
o = getRefById(''myID'' + i);
if(o) {o.innerHTML = ''Hello'';}
}
}

Use the name attribute if you must have equal names.
那没有比这更好的了。 DIV元素没有名称属性。

替换.invalid与.uk通过电子邮件回复。
That isn''t any better. The DIV element doesn''t have a name attribute.

Replace ".invalid" with ".uk" to reply by e-mail.

Hello,

myID.innerHTML = "Hello"
<DIV id="myID"></DIV>

I would like "Hello" to apear in each DIV with the ID of ''myID''. I do

ID *必须*在页面中是唯一的，因此您必须更改它们。
以下代码，我被告知，使用
类名称myclass循环遍历所有DIV元素。并将文本颜色更改为红色。
是否可以更改id =" myId" to class =" myclass"在你的页面上
然后改变下面的例程，这样它就会改变每个元素的innerHTML
在divs [i]中列出而不是文本颜色？
var divs = document.getElementsByTagName（''div''）;
if（divs）{
for（var i = 0; i< ; divs.length; i ++）{
if（divs [i] .className ==''myclass''）{
divs [i] .style.color = ''红色';
}
}
}
IDs *must* be unique within the page so you will have to change them.
The following code, I''ve been told, loops through all DIV elements with the
class name "myclass" and changes the text colour to red.
Would it be possible to change the id="myId" to class="myclass" on your page
then change the routine below so it changes the innerHTML of each element
listed in divs[i] instead of the text colour?
var divs = document.getElementsByTagName(''div'');
if (divs) {
for (var i = 0; i < divs.length; i++) {
if (divs[i].className == ''myclass'') {
divs[i].style.color = ''Red'';
}
}
}
