关于回车触发按钮点击的问题，请帮忙！

[liuvb]

我的代码如下：
为什么在第一个文本框按下回车键，可以触发'feebtn'按钮的onclick事件，在第二个文本框按下回车键，却不触发'feebtn'按钮的onclick事件，触发的是页面的另外一个按钮的(saveBtn)onclick事件，各位帮看看是怎么回事。

TextBox box=(TextBox)e.Item.FindControl("feeHowTxt");
TextBox box1=(TextBox)e.Item.FindControl("feeRemark");

if(box!=null&&box1!=null)
{
box.Attributes.Add("onkeydown","if(event.keyCode==13){document.getElementById('feebtn').click();}");

box1.Attributes.Add("onkeydown","if(event.keyCode==13){document.getElementById('feebtn').click();}");
}

关注，我没有发现什么问题

控件的得到焦点/失去焦点的问题

[zzxap]

改成这样
if(box!=null&&box1!=null)
{
box.Attributes.Add("onkeydown","if(event.keyCode==13){keyCode=9;document.getElementById('feebtn').click();}");

box1.Attributes.Add("onkeydown","if(event.keyCode==13){keyCode=9;document.getElementById('feebtn').click();}");
}

改成这样
if(box!=null&&box1!=null)
{
box.Attributes.Add("onkeydown","if(event.keyCode==13){event.keyCode=9;document.getElementById('feebtn').click();}");

box1.Attributes.Add("onkeydown","if(event.keyCode==13){event.keyCode=9;document.getElementById('feebtn').click();}");
}

楼上的说得就对

[wo594261]

if(box!=null&&box1!=null)
{
box.Attributes.Add("onkeydown","if(event.keyCode==13){event.keyCode=9;document.getElementById('feebtn').click();}");

box1.Attributes.Add("onkeydown","if(event.keyCode==13){event.keyCode=9;document.getElementById('feebtn').click();}");
}这样应该正确

这段代码 直接指定哪个文本框触发指定的按钮

// Configures what button to be clicked when the uses presses Enter in a 
  // textbox. The text box doesn't have to be a TextBox control, but it must 
  // be derived from either HtmlControl or WebControl, and the HTML control it 
  // generates should accept an 'onkeydown' attribute. The HTML generated by 
  // the button must support the 'Click' event
  public static void TieButton(Page page, Control TextBoxToTie, Control ButtonToTie)
  {
    // Init jscript
    string jsString = "";

    // Check button type and get required jscript
    if (ButtonToTie is LinkButton)
    {
      jsString = "if ((event.which && event.which == 13) || (event.keyCode && event.keyCode == 13)) {"
          + page.ClientScript.GetPostBackEventReference(ButtonToTie, "").Replace(":", "$") + ";return false;} else return true;";
    }
    else if (ButtonToTie is ImageButton)
    {
      jsString = "if ((event.which && event.which == 13) || (event.keyCode && event.keyCode == 13)) {"
          + page.ClientScript.GetPostBackEventReference(ButtonToTie, "").Replace(":", "$") + ";return false;} else return true;";
    }
    else
    {
      jsString = "if ((event.which && event.which == 13) || (event.keyCode && event.keyCode == 13)) {document."
          + "forms[0].elements['" + ButtonToTie.UniqueID.Replace(":", "_") + "'].click();return false;} else return true; ";
    }

    // Attach jscript to the onkeydown attribute - we have to cater for HtmlControl or WebControl
    if (TextBoxToTie is HtmlControl)
    {
      ((HtmlControl)TextBoxToTie).Attributes.Add("onkeydown", jsString);
    }
    else if (TextBoxToTie is WebControl)
    {
      ((WebControl)TextBoxToTie).Attributes.Add("onkeydown", jsString);
    }
  }
