js代码
<script> window.onload=function() { var oTab=document.getElementById('tab1'); var oBtn=document.getElementById('btn1'); oBtn.onclick=function() { var arr=[]; for(var i=0;i<oTab.tBodies[0].rows.length;i++) { arr[i]=oTab.tBodies[0].rows[i]; } arr.sort(function(tr1,tr2){ var n1=parseInt(tr1.cells[0].innerHTML); var n2=parseInt(tr2.cells[0].innerHTML); return n1-n2; }) for(var i=0;i<arr.length;i++) { oTab.tBodies[0].appendChild(arr[i]); } }; }; </script>
