Question

I have a function that detects all input value changes with keyup:

Jquery:

// detect all inputs

$('.inputChange').each(function() {
   // Save current value of element
   $(this).data('oldVal', $(this).val())

   // Look for changes in the value
   $(this).bind("propertychange keyup input paste", function(event){
      // If value has changed...
      if ($(this).data('oldVal') != $(this).val()) {
       // Updated stored value
       $(this).data('oldVal', $(this).val())
        currentVal = $(this).val()
       // Do action
       inputElement = $(this).attr('data-element')
       inputProperty = $(this).attr('data-property')
       inputUnit = $(this).attr('data-unit')
        updateAllCSS(inputElement, inputProperty, currentVal + inputUnit)
     }
   });
 });

HTML:

    <input class="inputChange" data-element=".homeTemplate #colaAlpha h1" data-property="font-size" data-unit="px">px

I now need to do another that will get the selected dropdown values from this HTML:

     <select class="selectChange" data-element=".homeTemplate #colaAlpha" data-property="height" data-unit="px">
         <option value="8">8px</option>
         <option value="12">12px</option>
         <option value="21">21px</option>
     </select>px

I was wondering how I should go about doing this? is there perhaps a propertychange event that will work?

Have a look at http://api.jquery.com/change/:

$(".selectChange").change(function (){
    alert($(this).val());
});
