jQuery Get All First Cells Of Table

Question

我需要获取某个表中所有行的所有tds（单元格），是否有一种优雅的方法来执行此操作，或者我需要以某种方式自己遍历集合？

Answer 1

try first-child

 $('table tr td:first-child')
 or
 $("table tr td:first")
 or
 $("table tr td").first()

Answer 2

此代码将返回表中所有id为tableId的tds

$('#tableId td')

Answer 3

Your question title is different from your question body. You may be interested in this solution, although I can't be sure:

$('#table_id tr td:first-child')

Answer 4

You have to loop it

Try this

$('#mytable tr').each(function() {
var customerId = $(this).find("td:first").html();    
});
