问题描述

您好，


我有一个gridview.关于这一点，我在gridview中有一个复选框.我在gridview之外还有一个按钮可以删除特定的选定行.我写了一些JavaScript函数来检查gridview中的复选框，并在onclient click事件中调用该函数.现在，我必须在删除该特定行之前显示确认消息.为此，我也在javascript中编写了一些构型函数.我如何在一个onclient click事件中调用这两个函数.

这是我的代码

Hi frnds,


I have a gridview. on that i have a checkbox in gridview. and i have one more button outside of gridview to delete particular selected row. I wrote some javascript function for checking the checkbox in gridview and iam calling that in onclient click event. Now i have to show confirmation message before deleting that particular row. for that one also i wrote some conformation function in javascript. how can i will call these two functions in one onclient click event.

Here is my code

function TestCheckBox()
   {       
   TargetBaseControl = document.getElementById('<%= this.GridView1.ClientID %>');
       
      if(TargetBaseControl == null) return false;
      
      //get target child control.
      var TargetChildControl = "CheckBox1";
            
      //get all the control of the type INPUT in the base control.
      var Inputs = TargetBaseControl.getElementsByTagName("input"); 
        var c=0;    
      for(var n = 0; n < Inputs.length; n++)
      {
     
         if(Inputs[n].type == 'checkbox' && 
            Inputs[n].id.indexOf(TargetChildControl,0) >= 0 && 
            Inputs[n].checked)
            {
               c++;
            // return true; 
            }
            
             
          }
          if(c==1)
          {
          return true;
          }
          else if(c>1)
          {
          for(var j=0;j<Inputs.length;j++)
          {
          Inputs[j].checked=false;
          }
          alert('Please select only one transaction');
          return false;
          }
          else if(c==0)
             {
          alert('Please select One transaction!');
              return false; 
            }
   }

another function is

function confirmdelete()
  {
  
  if(confirm("Are u sure delete partyhall")==true)
     return true;
     else
     return false;
  }

我的按钮代码是

And my button code is

<asp:Button ID="deletebtn" runat="server" Text="Delete Partyhall" BackColor="#0099FF"  Font-Bold="true" Font-Size="10pt" ForeColor="White" 

OnClientClick="javascript:return TestCheckBox();" onclick="deletebtn_Click" />

推荐答案

我不确定您可以尝试此方法

I am not sure you can try this

OnClientClick="javascript:return TestCheckBox();javascript:return confirmdelete()"
