jquery combines Ajax to double-click a table table to make the table editable and saved to the database

Recently in the project, to achieve by double-clicking the table Table of the TR, so that the table row can be editable, to achieve the ability to modify data and save to the database, no need to say, directly paste the code bar. I hope I can get my colleagues to correct you.

JS

Front Page bindings:

1 <tr ondblclick= "Tdedit (this, @item. ID)" ></tr>

Html

Eventually:
