How do I filtered TextBox with an Integer Data Type

验证用户输入的是否为整型。你可以使用下面正则表达式：

<asp:TextBox ID="txtWorkNumber" runat="server" onkeyup="value=value.replace(/[^\d]/g,'')"
                    onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
                    CssClass="textbox"></asp:TextBox>

 

或者使用asp.net验证Comparevalidator，有一个Type="Integer"，如：

 <asp:CompareValidator ID="CompareValidator3" runat="server" ControlToValidate="txtNumber"
                                                                            Type="Integer" Operator="dataTypeCheck" ErrorMessage="招聘人数栏位，非有效数值！"></asp:CompareValidator>
