I need to add a validation for a Particular value in Drop down Key.

Posted on Dec 15, 2012 at 04:30 AM 9 Views

1)

Requirement :

If user has selected a particular value then a pop-up should be initiated.

Ex : APPLE, ORANGE, GRAPE

I have wriiten the code to initiate pop-up message but i need to restrict for a particluar/ specific value.

Ex : Pop-up should be initiated only if User selects "APPLE".

2)

Is there a way that we can write a validation,

Ex : IF last value in a given input is numeric it should raise an error mesage?

Ex : CHAT - Is the correct way

CHA1 - This value should be validated saying that 'It is inavled value, kindly select correct value.'

In a given input if the last value is numeric then it should display an error message.

How can i write the IF conditions for the above two scenarios.

I am using NWDS 7.0

Any suggestions will be appreciated!

Thank you!

Best Regards,

KC

    Hi Krishna,

    1) you can get the value of selected element of the context that is binding in your drop dowm component when you select some value in drop down. To do this you need to create an action and bind this action in onSelect Event in WebDynpro. When the value is selected, the current element of the binding context of drop down will be change.

    To get the value of the selected context: wdThis.current<NAME OF CONTEXT ELEMENT>Element.get<ATTRIBUTE>(), for example wdThis.currentFruitElement.getFruitName().

    So, with this value you can use IF state to define the process.

    2) you can use a regex of java api to verify the pattern of the value.

    Regards
