jQuery表找到最接近的tr包含并获取td文本

Question

This datatables has row-reordering so its drag and drop. What I am trying to do is find the Parent this row is dropped into and get the Parent id. Hopefully someone can tell me where I am going wrong...

This line successfully gives me the tr id

var line = parseInt($(this).attr('id'));

So I'm using this to get the closest above Parent (check the image)

var s = $(this).find('tr:contains("Parent")'); 

What I can't seem to do is get to any td value

var s = $(this).find('tr:contains("Parent")').find('td:eq(17)').text()

I've also tried this

var s = $(this).closest('tr').prevAll('tr.Parent:first > td:nth-child(17)').text()

Answer 1

It looks like you want to simply take the "parent ID" value from column (index 14) and use it to find the row that simply has ID="that parent number" :

eg

  var parent = $('#' + $(this).children().eq(14).text());
