我在网格视图中隐藏了字段值我用linq查询绑定了我想通过asp：link按钮获取所选字段值我的asp.net代码是：
 
 
 <   pre     lang   =  c＃ >  <   asp：TemplateField  < span class =code-keyword>>  
 <   ItemTemplate  >  
 <   asp：LinkBut​​ton     ID   =  EditButton    runat   =  server    CausesValidation   = 错误    CommandName   =  EditCol > 编辑<   / asp：LinkBut​​ton  >  
 <   / ItemTemplate  >  
 <   / asp：TemplateField  >  
 <   asp：TemplateField  >  
 <   ItemTemplate  < span class =code-keyword>>  
 <  输入    id   =  Hidden1    runat   =  server    type   = 隐藏   可见  =  true    class   =  H    value   ='  <％ #Bind（  MBody）％> '    /  >  
 <   / ItemTemplate  >

 $（ document ）。on（ 点击，   [id * = EditButton]， function （event）{
 event.preventDefault（）; 
  var  body = $（  [id * = Hidden1]）VAL（）; 
 alert（body）; 
} 

它只显示第一个边界字段值未选择值你能帮我解决这个问题吗？

解决方案

（ document ）。on（ 点击， [id * = EditButton] ， function （event）{
event.preventDefault（）;
var body =

（ [id * = Hidden1]）。val（）;
alert（正文）;
}

它只展出了第一个边界字段值没有选择值你能帮我解决这个问题吗？

你正在使用模板，所以你的id永远不会出现在网格中，否则你应该最终得到了许多具有相同id的元素。想想有10行的数据集！在每一行都有一个隐藏字段，但它们的ID必须不同！

您可以使用基于类的jQuery选择器：

i have hidden field value inside a grid view i bound it with a linq query i want to get selected field value through asp:link button my asp.net code is :


<pre lang="c#"><asp:TemplateField>
                            <ItemTemplate>
                                <asp:LinkButton ID="EditButton" runat="server" CausesValidation="False" CommandName="EditCol">EDIT</asp:LinkButton>
                            </ItemTemplate>
                        </asp:TemplateField>
 <asp:TemplateField>
                            <ItemTemplate>
                                <input id="Hidden1" runat="server" type="hidden" visible="true" class="H" value='<%# Bind("MBody") %>' />
                            </ItemTemplate>
                        </asp:TemplateField>

when i want to get selected row value using this jquery code :

$(document).on("click", "[id*=EditButton]", function (event) {
            event.preventDefault();
            var body = $("[id*=Hidden1]").val();
alert(body);
}

it just exhibits the first bounding field value not selected value could you please help me to overcome this issue ?

("[id*=Hidden1]").val(); alert(body); }

You are working with templates, so your ids are never will be presented in the grid, otherwise you should end up with numerous elements with the same id. Think about a data set with 10 rows! In every row there is a hidden field, but their ids must be different!
You may use a class based jQuery selector:
