slider value

[nace186]

I created a slider with the following rml:

Code: Select all

<input id="test_slider" type="range" min="0" max="10" value="0" style="width: 100px;" onchange="one" />

and in the event handler, I have the following:

Code: Select all

         
   if (pFile!=NULL)
   {
      fprintf(pFile, "slider value %s \n", event.GetCurrentElement()->GetAttribute< EMP::Core::String >("value", "1") );
   }


I'm able to drag the slider, but the slider value saved in the file is always zero. How can I get the value that is submitted by the user?

The RML appears to be correct. When you're fprinting the value of the variable however, there should be a .c_str() on the end of the call to GetAttribute to convert the EMP::Core::String into a const char*. I don't know if that's the problem; if that doesn't work, try changing the initial value of the slider and seeing what the value is reported as then.
