jquery find tr td example simulation_jquery

Someone suddenly asked me in the group today why the statement $("#MainContent_GridView1").closest("tr").children("td:eq(1)").text() cannot find the value. I asked him whether to take the text of the td of eq(1) under a tr or all of them. He said everything. . . . Then you must loop through all tr ​​and then find td among them. . .

Here I write a simple blog to help those friends who still don’t know how to use jquery selectors.

I simulated a table for your reference. The following is the html structure

Copy code The code is as follows:

< td>2


;td>22

1	3
33
111	222	333

//I introduced the local jquery file, but I will not introduce it in the article.
