需要您的帮助.
谢谢大家.

推荐答案

这是因为您在第一次单击时添加了javascript.在第二次单击时，JavaScript已存在，因此正在执行.您必须提前添加脚本(例如，在绑定时).不过，最简单的方法是添加
该JavaScript到您的标记.

希望对您有帮助

忘了:除此之外，您可以立即运行脚本，而无需使用onlick处理程序. Google for"asp.net javascript RegisterStartupScript"或将其写入您的响应流

Hi,

this is because you add the javascript at that first click. At the second click, the javascript is existing and therefore being executed. You have to add the script earlier (e.g. on binding). The easiest way though would be to add
that javascript to your markup.

Hope that helps

Forgot: In addition to that, you could run your script immediatly without using the onlick handler. Google for "asp.net javascript RegisterStartupScript" or write it to your response stream

此代码将在首次点击时被执行.因此，按钮的onclick属性将仅从第二次开始生效.因此，您可以在像这样的行数据绑定事件上为图像"按钮添加onclick属性..

this code will be excuted on first click. So, the onclick attribute for the button will affect only from the second time. So, You add onclick attribute for the Image button on Row data bound event like this..

// on row data bound event

 if(e.Row.RowType == DataControlRowType.DataRow)
 {
      Image img = (Image)e.Row.FindControl("imgSMS");
      img.Attributes.Add("onclick","window.open('Admin/Default.aspx','_blank','toolbar=0,location=0,menubar=0,resizable=0,height=300,width=300');return false");
 
 }

希望它能工作..

hope it works..
