可以将命令参数和onclick事件添加到div吗？ [英] Can command argument and onclick event be added to a div?

问题描述

我有一张相册（不是图库），用它预览照片。根据与用户关联的专辑数量动态生成专辑。我想在其上添加点击事件，以便当一个人点击一个专辑时，它会将他带到该专辑中的照片。我是初学者所以我不知道如何做到这一点。但我认为添加命令参数应该可以解决问题。



ASPX代码：

 for（int i = 0; i <     dt5.Rows.Count;     i ++）  
   
   {  
   
           string     q     = 从照片中选择imageurl，其中albumid ='    
   
          < span class =code-attribute>                                                                         +    < span class =code-attribute> dt5.Rows [i] [albumid]。ToString（）    +    ';   
   
           dt6     =   dbo.Getdt（q） ; 
   
           a     =   dt6.Rows [0] [  imageurl]。ToString（）;   
   
           b     =   dt6.Rows [1] [  imageurl]。ToString（）;   
   
           c     =   dt6.Rows [2] [  imageurl]。ToString（）;   
   
           a   =   a.Substring（1，  a.Length      -      1）;   
   
           b     =   b.Substring（1， < span class =code-attribute> b.Length      -      1）;   
   
           c     =   c.Substring（1，  c.Length  < span class =code-attribute>    -      1）;   
   
      ％ >  
 <   div     id   =  Div1      class  < span class =code-keyword> =  image_stack    style   =  margin-removed300px;已删除418px;        
   
                     runat   = 服务器 >  
 <   img     id   =   Img1      class   =  stackphotos photo1    src   =  <％：a％>        /  >  
 <   img     id   =  Img2      class   =  stackphotos photo2    src   =  <％：b％>      /  >  
  <   img     id   =  Img3        class   =   stackphotos photo3    src   =  <％：c％>    /  >  
 <   / div  >  
 <   br     /  >  < ;   br     /  < span class =code-keyword>>  <   br     /  >  <   br     /  >  
 <％}％> 

在上面的代码中，image_stack是div，它用于使用Jquery插件显示相册。

解决方案

你无法添加Div / Panel控件的CommandArgument / Comamnd事件

您可以添加LinkBut​​ton / ImageButton或Button来满足您的要求，并将该按钮添加到Div

< div id =   Div1 < span class =code-keyword> class  =   image_stack >  
 runat =   server < span class =code-keyword>>  
< asp：linkbutton id =   linkBut​​ton text =   text commandargument =   1 commandname =   GetAlbum runat =   server xmlns：asp =  ＃unknown >  
< img id =   Img1  class  =   stackphotos photo1 >  
< img id =    Img2  class  =   stackphotos photo2 >  
< img id =   Img3  class  =   stackphotos photo3 >  
 < /   div  >  

I am have a photo album(not gallery) which previews the photos withing it. The albums are dynamically generated depending on number of albums associated with the user. I want to add on click event to it so that when a person clicks an album it takes him to the photos within that album. I am beginner so I do not exactly know how it can be done. But I think adding command arguments should do the trick.

ASPX CODE:

for (int i = 0; i < dt5.Rows.Count; i++)

{

    string q = "select  imageurl from photos where albumid='" 

                                        + dt5.Rows[i]["albumid"].ToString() + "'";

    dt6 = dbo.Getdt(q);

    a = dt6.Rows[0]["imageurl"].ToString();

    b = dt6.Rows[1]["imageurl"].ToString();

    c = dt6.Rows[2]["imageurl"].ToString();

    a= a.Substring(1, a.Length - 1);

    b = b.Substring(1, b.Length - 1);

    c = c.Substring(1, c.Length - 1);

  %> 
   <div id="Div1"  class="image_stack" style="margin-removed300px ; removed 418px;"   

         runat="server">
       <img id="Img1"  class="stackphotos photo1" src="<%: a %>"   />
       <img id="Img2"  class="stackphotos photo2" src="<%: b %>"  />
       <img id="Img3"   class="stackphotos photo3" src="<%: c %>" />
   </div>
     <br /><br /><br /><br />
<% } %>

In above code image_stack is the div which is used to show album using Jquery plugin.

解决方案

You can not add CommandArgument/Comamnd Event to Div/Panel control
Instead of it you can add on LinkButton / ImageButton or Button to fulfil your requirement and Add that button to Div

<div id="Div1" class="image_stack">
         runat="server">
        <asp:linkbutton id="linkButton" text="text" commandargument="1" commandname="GetAlbum" runat="server" xmlns:asp="#unknown">
       <img id="Img1" class="stackphotos photo1">
       <img id="Img2" class="stackphotos photo2">
       <img id="Img3" class="stackphotos photo3">
   </div>
