B4J Question How to Insert B4J line into Javascript ?

[Pravee7094]

Hi all,
we are making a small website using b4j and html.
Doubt is, In B4j we just add this feature such as If I click the delete button, the alert box will appear.
In that alert box, there is yes or no question (Are you sure want to delete ? ). I think all of them know this feature.

Here my sample code :

        Dim str As String
        str = $" $(function(){
              if (confirm("Are you sure want to Delete?")) {
                  return true;
              }
                  return false;
                  }); "$

        is_websocket.Eval(str,Null)

In that above code, If action is true the delete operation done here. Delete code is here,

sql1.ExecNonQuery2("delete from gl_uom where uompk = ? ", Array As Object(ls_uompk))

How can I insert the b4j code into the js code ?
I want this deletion code instead of this "return true; " code.

Any suggestion or Help? or Any other relevant code is available for html pages with b4j ?

Regards
Praveen

The js code runs on the browser. It cannot run your B4J code and it cannot directly access the server database.

You can use b4j_raiseevent to raise an event on the server: https://www.b4x.com/android/forum/pages/results/?query=b4j_raiseEvent
