原先希望这个textbox只能输入数字和小数点，现在下面的代码只能输入数字，不能输入小数点，请教高手帮忙，谢谢！小数点（.）的keyCode是110
<asp:textbox BackColor= "#EBEBEB " BorderStyle= "inset " style= "height: 12px;width: 160px;font-family: Arial, Verdana, Tahoma, Sans-Serif;font-size: 12px;vertical-align: middle;margin-left: 5px;padding-top: 4px;padding-left: 2px; " id= "vendor " runat= "server " onkeypress= "if (event.keyCode < 48 || event.keyCode > 57) event.returnValue = false; "/>
------解决方案--------------------------------------------------------
经测试应为
onkeypress= "if (!((event.keyCode > = 48 && event.keyCode <=57) || event.keyCode == 46 )) event.returnValue = false; "
