is there js or jquery function observe if innerhtml or text within # of pixels beingness clipped container?

i need few hundred elements on page, performance bit important.

example - determine if text in <td> within 5px of exceeding width:

<td class="cell"> 12,3423 </td> .cell { width: 20px; }

try

$.fn.textwidth = function(){ var html_org = $(this).html(); var html_calc = '<span>' + html_org + '</span>'; $(this).html(html_calc); var width = $(this).find('span:first').width(); $(this).html(html_org); homecoming width; }; $(function(){ alert($('.cell').textwidth()); });
