Accessing dynamic attribute

Post by terrynweze on Thu Mar 01, 2012 5:34 pm


I am struggling to get the value of an elements attribute that is generated dynamically

attribute data-state seen below is dynamically generated and changes
between closed & open depending as to whether or not the select
object is expanded or collapsed.

<1select id="state" class="validatable" data-vrule-required="true" data-vmessage-prefix="requestQuoteFormTemplate.state" name="state" data-state="closed">

The code i am using to access the attribute is as follows:

public boolean isStateDropDownMenuExpanded() {
return getElementBy("state")).getAttribute("data-state").equalsIgnoreCase("open");

get a null pointer exception as the attribute data-state is not found.
When i look at the source code for the page i can see that the attribute
is not seen within the source (see extracted source code below)

name="state" id="state" class="validatable"

any help with this problem would be greatly appreciated.

Note: i have added the number 1 within the select elements above as without it an actual select object is displayed on the page within this forum.

Hello All,

Managed to solve this issue myself and feel a little stupid for not seeing the solution straight away.

I used some javasecript to get the value of the attribute and passed it back into the application

JavascriptExecutor exec = (JavascriptExecutor) webDriver;

String elementState = (String) exec.executeScript("return document.getElementById('state').getAttribute('data-state')");
