Jquery gets the row and column of td, and jquery gets the row and column of td.

When I was working on a project today, I encountered a problem where I needed to obtain the nth column of the row. Later, I searched for information online and sorted out this article. (Use jquery's preAll () to retrieve columns)

 

The Code is as follows:

<! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 

The test results are as follows:


Who will help me solve this problem and how to obtain the row and column of <a> td through js (jquery )?
<Table border = "1">
<Tr>
<Td colspan = "2"> <a onClick = "alert (this. parentNode. parentNode. rowIndex)"> xxxx </a> </td>
</Tr>
<Tr>
<Td> <a onClick = "alert (this. parentNode. cellIndex) "> xxxx </a> </td> <a onClick =" alert (this. parentNode. cellIndex) "> xxxx </a> </td>
</Tr>
<Tr>
<Td colspan = "2"> <a onClick = "alert (this. parentNode. parentNode. rowIndex)"> xxxx </a> </td>
</Tr>
</Table>

How can I use Jquery to obtain the row number of the specified td content?
$ ("Table tr"). each (function (I ){
Var index = 0;
If ($ (this). find ("td"). get (1). text () = 'zhang san '){
Index = I;
}
})
