Question

I have to access all the elements at parent level.
table
tr
td id=”id”
tr
tr
table

Here based on td id I have to select all the rows and hide it.

Answer 1

you can simply do

$("#tableID tr")

it will select all the immediate tr of the table with id tableID, moreover you can also select all the tr and examine the id

$("#tableID tr td").filter(return $(this).attr('id')!='idOfYourChoice').hide();

it will hide all the td except with the id='idOfYourChoice'
