    Is it possible to assign a value to a variable onclick? I know that I can assign a value to an input field, but I wanted something where I could do this:

    var mysample = '';

    <input type="button" id="sample0" onclick="mysample is assigned the value of 0" />

    Possible?

    Yep, I'd go about it within the onclick attribute, unless you intend to use it multiple times, then place it into a function and call the function w/ onclick

    onclick="this.value='my sample is assigned a value of '+x.toString();"
