Selecting multiple checkboxes from a table javascript : <p>first question here and novice programmer, i'll try to keep it simple and to the point. </p>

<p>In my HTML code, I have a table consisting of hundreds of rows, with a checkbox next to each one, so the user can 'select' which lines they want. I need to have it so if the user picks lines, lets say line 300 and line 400 (arbitrary numbers), lines 300-400 will all be checked. I'm not quite sure at all how to do this, my coworkers say it is possible, any help would be greatly appreciated. Thanks guys.</p>
