Firefox中的getElementsByTagName [英] getElementsByTagName in Firefox
问题描述
您好。我有以下代码行在IE中运行良好...
line_1_numbers [0] = document.getElementsByTagName
（''table ''）[table_index] .rows（0）.cells（0）.innerText;
但它是Firefox，它咆哮说：
"错误：document.getElementsByTagName（" table"）[table_index] .rows不是
函数"
任何想法意味着什么？
感谢您的帮助，
问候，
Dan。
Hi. I''ve got the following line of code which works fine in IE ...
line_1_numbers [0] = document.getElementsByTagName
(''table'')[table_index].rows (0).cells (0).innerText;
But it Firefox, it barks saying:
"Error: document.getElementsByTagName("table")[table_index].rows is not a
function"
Any ideas what this means?
Thanks for any help,
Regards,

IE允许您使用（）
表示法来处理集合中的索引。改为使用[]。
line_1_numbers [0] = document.getElementsByTagName（''table''
）[table_index] .rows [0] .cells [0]。 innerText;
thing（）用于函数。
thing []用于数组/列表。
IE is broken by allowing you to address indices in collections using ()
notation. Use [] instead.
line_1_numbers [0] = document.getElementsByTagName(''table''
)[table_index].rows[0].cells[0].innerText;
thing() is for functions.
thing[] is for arrays/lists.

对innerText的支持是有限的（几乎与IE相同），常规的
表达式可用于从单元格的innerHTML中移除标签到
实现了几乎相同的结果。类似于：
var re = /< [^>] *> / g;
应该可以解决问题。或等待DOM 3得到广泛支持并使用
textContent ;-p

并非所有浏览器都支持单元格集合（想想
Safari ......）。 childNodes集合可能是更好的选择，并且在这种情况下功能相当于
，因为只有一个单元格（TR | TH）可以是TR的孩子。
var re = /< [^<>] +> / g;
line_l_numbers [0] = ... rows [0]。 childNodes [0] .innerHTML.replace（re，''''）;

Support for innerText is limited (pretty much to IE), a regular
expression can be used to remove tags from the cell''s innerHTML to
achieve pretty much the same result. Something like:
var re = /<[^>]*>/g;
should do the trick. Or wait for DOM 3 to be widely supported and use
textContent ;-p

The cells collection is not supported by all browsers (think
Safari...). The childNodes collection may be a better choice and is
functionally equivalent in this case as only a cell ( TR|TH ) can be a
child of a TR.
var re = /<[^<>]+>/g;
line_l_numbers[0]=...rows[0].childNodes[0].innerHTML.replace(re,'''');

即使我认识他们，我也完全错过了这两点。
这就是为什么我在这里不是一张非常多产的海报。 ;）
Both excellent points that I missed entirely even though I knew them.
This is exactly why I''m not a very prolific poster here. ;)
