Ajax笔记

1.检测输入的是否汉字

JavaScript.js
function validateName(Name)
{
    //创建一个正则表达式
    var regex = new RegExp("^[\u4e00-\u9fa5]{0,}$");
    //检测字符串是否与给出正则表达式匹配
    return regex.test(Name);
}

default.aspx
<title>无标题页</title>
    <script type="text/javascript">
        function Button1_onclick()
        {
            if(!validateName(document.getElementById("Text1").value))
            {
                alert("输入不是汉字，请重新输入");
                document.getElementById("Text1").value = "";
                document.getElementById("Text1").focus();
            }
        }
    </script>
<form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server">
            <Scripts>
                <asp:ScriptReference Path="~/JavaScript.js" />
            </Scripts>
        </asp:ScriptManager>
        输入名字:<input id="Text1" type="text" />
        &nbsp;<input id="Button1" type="button" value="确定" onclick="Button1_onclick()" />
    </form>
