How to get the 'text' property value of a button in coding?

[Former Member]

Hi Experts,

I'm using 10 buttons all are having common action('click'). when i click a button the 'text' value of the button should pass to a function.So the action is same but the passed value will be the 'text' value of the corresponding button. I don't know how to get the 'text' property of a button in coding. Kindly help me to solve this problem.

Thanks and Regards

Hi,

For getting the text value property of a button after the Button click you can write the following code in wdDoModify view of view:

IWDButton button = (IWDButton)view.getElement("<Button id>");

button.getText();

But i am not sure how you distinguish between which button is clicked ,Because you are using same event handler for all of them.

Hi,

bind the button text property with context attribute of string.

InDoinit of view set the required name.

when ever you require you can get it like this,

wdContext.currentContextElement().getButtonName();

That would require 10 additional context attributes.

Hi Armin,

Hi,

My event is like this.

public void onActionclick(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

{

String s = ? ; // should get the 'text' property of clicked button

fillInput(s); // function to be called

}

The called function is,

public void fillInput( java.lang.String id )

{

String str=wdContext.currentContextElement().getNum();

str = str + id;

wdContext.currentContextElement().setNum(str);

}

How can i get the 'text' property value of the corresponding button. Click action should be common to all buttons.

Just read my answer above.

I did not say that your proposal is wrong, but creating 10 additional attributes is a little bit tedious in that case. Using method wdDoModifyView() for what it is designed is perfectly ok.

I am not sure why you need the (localized) button text in the action handler but you can achieve this using event parameter mapping:

wdDoModifyView(...)
{
  if (firstTime)
  {
    /* assuming the buttons are named "Button1", "Button10" */
    for (int i = 1; i <=10; ++i)
    {
      IWDButton button = (IWDButton) view.getElement("Button" + i);
      button.mappingOfOnAction().addParameter("text", button.getText());
    }
  }
}

Now if you add a parameter "text" of type string to the common action handler, it will contain the text of the pressed button.
