return;

} 

var mtext = divedit.text().substring(0, divedit.text().length-10); 

var inputIns = $("<input type='text'/>"); //创建input 输入框 

var oldtext = divedit.html(); //保存原有的值

inputIns.width(divedit.width()); //设置INPUT与DIV宽度一致 

inputIns.val(mtext); 

divedit.html(""); //删除原来单元格DIV内容 

inputIns.appendTo(divedit).focus().select(); //将需要插入的输入框代码插入DOM节点中

inputIns.click(function () {

return false; 

}); //处理回车和ESC事件 

inputIns.keyup(function (event) { 

var keycode = event.which; 

if (keycode == 13) { 

var newText = oldtext.replace(mtext, $(this).val()); 

divedit.html(newText); //设置新值 

} 

if (keycode == 27) {
