采用弹出气泡方式进行客户端输入验证
来源：互联网 发布：php代码注入原理 编辑：程序博客网 时间：2024/06/09 14:27
在web页面中进行js验证，是一件非常麻烦的事儿，要重复写很多代码。
采用扩展属性+js遍历模式，可以减少重复代码的编写，提高开发效率：
<asp:TextBox Msg="Decimal类型" DataField="InvestigateMan" IsNull="false" FieldType="decimal"
precision="6,2" ID="InvestigateManTextBox" runat="server" CssClass="t_common"></asp:TextBox>
<span name="ValueData" style="color: Red;">*</span>
扩展属性：Msg, DataField, IsNull, FieldType
遍历脚本：
/*
*/
var isShowTip = false; //是否已经显示了Tip
var isShowCustomTip = true; //是否显示自定义验证的Tip
var msgValue = "";
var retValueKind = false;
var RegexMark = "##";
//常量
var MaxLength = "maxLength";
var TextLength = "TextLength";
var isIE = false;
//alert(document.all);
if (document.all != undefined)
{
isIE = true;
}
