I have form:

<form onchange="allvaluestostring()">

    <select name="status">

         <option value="*">All</option>

         <option value="1">Active</option>

         <option value="0">Inactive</option>

    </select>

    <select name="size">

          <option value="*">All</option>

          <option value="small">Small</option>

          <option value="big">Big</option>

    </select>

</form>

And the onchange action of any input in form I need to get a JavaScript string, for example "status=1&size=big" for using in httprequest.

Does there exist something in JavaScript that will take all form values when one of form inputs will be changed?

I used <select name="status" onchange="showExporteditems(this.name,this.value)">, but this will take only one input value for using only "status=1", but I need on each onchage all values from all inputs for string like "status=1&size=big&...etc....".

Without using jQuery.
