List

Description

The List control is used a menu list. Each line can have a name, a number and an image. Selecting one will call <ListID>_onclick(i), with i containing the line number chosen. To get the text of the list item that was called,use the expression List_jqm1.children[i].innerText in your onclick function.

To add a control to your app, choose the control’s icon in the Toolbar, then position it on the Design Screen. Use the Property Editor to set the properties you need, then add functions to your code to respond to the events that come from the control: usually, just onclick.

  MsgBox "Menu item chosen: " & i & " " & List1.getItem(i)
End Function

Example (JavaScript)

  if(typeof i == "object") return;
  alert("Menu item chosen: " + i + " " + List1.getItem(i));
}

Items can be formatted using HTML:

List1.addItem("<table><tr><td width=30>1</td><td width=200>Beschreibung</td><td>19.99</td></tr></table>")

You can change the color of the selected item:

List1.children[i].style.background="yellow"
