模板字段和href属性? [英] Template field and href attribute ?

问题描述

我有以下asp鳕鱼:

I have the following asp cod:

<asp:Repeater ID="rpt1" runat="server" onitemdatabound="rpt1_ItemDataBound">
  <ItemTemplate>
    <div style="float:left; padding-removed4px"><%# Eval("Name") %>  </div>
     <div style="float:left; padding-removed4px"><%# Eval("CollectionType")%></div>
     <div style="float:right">
     <a href="AddItem.aspx?c=<%# Eval("CollectionID") %>">[edit item]</a>
     </div>
     <br />
  </ItemTemplate>
  </asp:Repeater>

您能解释一下该asp行中发生了什么吗?

Can you explain please what is occurring in this asp row?

<a href="AddItem.aspx?c=<%# Eval("CollectionID") %>">[edit item]</a>

预先谢谢您.

Thank you in advance.

推荐答案

在上面您已经创建了AddItem.aspx的链接.

在?"之后，您已定义了一个参数.在这种情况下，您有一个参数"c".

要设置参数，请在c后面加上"=".

最后，您通过调用<％Eval("CollectionID")％>从数据源设置了参数"c".

如果您在传递参数值时遇到问题，请尝试将左引号和右引号改为单引号.

< a href ="AddItem.aspx?c =<％Eval(" CollectionID)％>"> </a>至:

< a href =''AddItem.aspx?c =<％Eval("CollectionID")％>''> </a>

现在，只要您单击行中的链接，它就会将您重定向到AddItem.aspx并通过CollectionID参数.

这有用吗?

Above you have created a link to AddItem.aspx.

After the ''?'' you have defined a parameter. In this case you have a parameter ''c''.

To set the parameter you follow the c with ''=''.

Finally you have set the parameter ''c'' from the datasource by calling <% Eval("CollectionID") %>.

If you are having problems with this passing the parameter value try changing the opening and closing double quotes to single quotes.

<a href="AddItem.aspx?c=<% Eval("CollectionID") %>">[edit item]</a> to:

<a href=''AddItem.aspx?c=<% Eval("CollectionID") %>''>[edit item]</a>

Now anytime you click the link in the row it will redirect you to AddItem.aspx and also pass through the CollectionID parameter.

Is this helpful?
