Question

我有

<asp:TextBox runat="server" ID="TextBox1" value="<%$ Resources: WebResource, Search %>" onblur="if(this.value=='') this.value='Search';" onfocus="if(this.value=='Search') this.value='';" />

我怎样才能为onblur做这样的事情

<asp:TextBox runat="server" ID="TextBox1" value="<%$ Resources: WebResource, Search %>" onblur="if(this.value=='') this.value='<%=Resources.WebResource.Search %>';" onfocus="if(this.value=='<%=Resources.WebResource.Search %') this.value='';" />

本地化JavaScript内联？

您可以使用数据绑定表达式（<%# %>）：

<asp:TextBox 
    runat="server" 
    ID="TextBox1" 
    value="<%$ Resources: WebResource, Search %>" 
    onblur='<%# string.Format("if(this.value==\"\") this.value=\"{0}\"", Resources.WebResource.Search) %>'
    onfocus='<%# string.Format("if(this.value==\"{0}\") this.value=\"\"", Resources.WebResource.Search) %>'
/>

请务必在页面上致电DataBind。或者在后面的代码中：

TextBox1.Attributes["onblur"] = string.Format("if(this.value==\"\") this.value=\"{0}\"", Resources.WebResource.Search);
TextBox1.Attributes["onfocus"] = string.Format("if(this.value==\"{0}\") this.value=\"\"", Resources.WebResource.Search);

将资源中的字符串放在单引号之间
