Sometimes we need to add the javascrip script to the web control button. For example, after clicking a button, a confirmation dialog box is displayed. When the user clicks "OK" or "cancel", the next operation is performed, if this process is completely on the server side CodeIt is very difficult to implement, so you need to append the javascrip script on this button.
Add the attributes. Add (key as string, value as string) Statement to the button.
Example:
Revoke Delete. Attributes. Add ("onclick", "javascript: Return confirm ('" & Localization. getstring ("deleteitem ")&"');")
......
Private sub extension delete_click (byval sender as object, byval e as eventargs) handles into Delete. Click
'Processing statement
End sub
The confirm delete button indicates the button ID. After you click the delete button, a dialog box is displayed. After the user confirms the deletion, the delete operation is performed.
