asp.net ajax有现成的控件一拖就可以加入了：

为什么输入一个6就变成0.06 输入2个6就变成0.66？怎样自己输入小数点？而不是自动写入？

这是JS方法



function onKeyPrice(t) 

{ 

    var stmp = ""; 

    if(t.value==stmp)

    {

        return; 

    }

    var ms = t.value.replace(/[^\d\.]/g,"").replace(/(\.\d{2}).+$/,"$1").replace(/^0+([1-9])/,"$1").replace(/^0+$/,"0"); 

    var txt = ms.split("."); 

    while(/\d{4}(,|$)/.test(txt[0])) 

    {

       txt[0] = txt[0].replace(/(\d)(\d{3}(,|$))/,"$1,$2"); 

    }

    t.value = stmp = txt[0]+(txt.length>1?"."+txt[1]:""); 

}

在文本框里面加onkeyup事件行了



<asp:TextBox ID="TextBox1" runat="server" onkeyup="onKeyPrice(this);"></asp:TextBox>
