如何根据该行中的单元格获取行索引 javascript

Question

So basically my php file will return an echo (as a table), and in that table, each row will have a cell that is a delete button to delete that row. whatI want is when button clicked, the row will be delete from table. So I guess the row index is important to implement this. But how can I get row index in this situation in javascript?

Answer 1

DOM table element has the method deleteRow and you can get the row index of a table row using rowIndex attribute.

var myTable = ...
var rowIndex = btn.parentNode.parentNode.rowIndex;
myTable.deleteRow(rowIndex);`
