jQuery可编辑的表格如何通过PHP更新数据到MySQL?

function tdclick()  

{  

    var clickfunction = this ;

    var td = $(this)  

    var text = td.text();

    td.html("");

    var input = $("<input>");

    input.attr("value", text);

    input.keyup(function(event) {  

        var myEvent = event || window.event;  

        var kcode = myEvent.keyCode;

         if (kcode == 13)  

        {  

            var inputnode = $(this);  

            var inputext = inputnode.val();  

            var tdNode = inputnode.parent();  

            tdNode.html(inputext);  

            tdNode.click(tdclick);  

        }  

      if(kcode == 27)   

       {  

          var inputNode = $(this);  

          var inputText = text;  

          inputNode.attr("value",text);  

       }  

    });  

    td.append(input);

    var inputdom = input.get(0);

    inputdom.select();

    td.unbind("click");  

}
