我有以下 JavaScript 代码。
var myCellCollection = document.getElementById( myTbl ).cells;
这在 IE 中效果良好, 它返回一个表格单元格集。 但相同的行返回 Firefox 中的“ 未定义 ” 。 我使用 IE 9 和 Firefox 12 。

您应该使用 document. getEplementById (" MyTbl").getEplementsByTagName (td)
;
今天在移植一个更老的互联网探索者应用程序时 陷入了这个困境。
Warning:
container.getElementsByTagName( tagname )
returns ALL the elements inside container
that matches the query tagname
.
Thus table.getElementsByTagName( td )
will return all td
s including those of nested tables!
However table.cells
doesn t do that (where implemented).
而且,显然,它不会匹配 < code>th 。 因此这些单元格不在返回的收藏中, 导致如何解决相对于 td s 的顺序问题...
如果要将 DOM-order 中的 table. cells
(返回 th
和
/code > 的预期功能舍姆,我写了以下简单功能:
function tableCells(t){
if(t.cells) return t.cells; // use internal routine when supported
for(var a=[], r=t.rows, y=0, c, x; t=r[y++];){
for(c=t.cells, x=0; t=c[x++]; a.push(t));
}
return a;
}
conccaccatt code> - 输入
accod. rows[X]. ells
, 但效果不佳( 虽然我感觉不安全)
Usage example:
var identifier = tableCells( /*reference to table (or thead/tbody/tfoot) here*/ );
It will return an array (not a live collection) like the result from table.cells
.
希望这能帮到某人
