.exists

Use

You use the .exists attribute to determine whether a screen field exists on the screen.

Example

The following code determines whether the vbcom-kunde field exists on the screen and whether it is ready for input:

`if ( vbcom-kunde.exists )`

`if ( vbcom-kunde.disabled )`

<! Value only -->

`vbcom-kunde`

`else`

<! ready for input -->

<input

type="text"

name="vbcom-kunde"

value "`vbcom-kunde`">

`endif`
