How to change text field size by drop-down list value

[eugzl]

Hi All.

I have drop-down list and text field in the form and Iwould like to change high and width by selecting value in drop-down list. If that is possible how to do that?

Thanks.

You could do that by executing JS code on submitting the Touch UI dialog. The JS code can pick the values from JCR and modify HTML DOM accordingly

Here's some example to handle touch UI dialog events.

Hi Bharath. Thanks for replay.

Yes, I need JS code in event change of drop-down list with IF statement. It should be look like:

if(xfa.event.newText == "Other")

   TextField.presence.w = "2 in";

   DropDownList.w = "1 in";

else

   TextField.presence.w = "1 in";

   DropDownList,w = "2 in";

But that code doesn't work. My problem how correct to specify width in the JS code. How to fix it?

Thanks.

Hi,

you can get value from dropdown and applied to text field.

(function(document, $) {

    "use strict";

$(document).on("selected", "#dropdownId", function(e) {

    var selectVal = $(this).val();

    $("#textFieldId").attr("size", selectVal);

  });

})(document, Granite.$);
