推荐答案

单向，您可以将currentrowindex作为自定义属性添加到Grid的RowDataBound事件中的文本框中。您将在此事件中轻松将索引添加为属性。现在你可以在javasctipt上访问相同的属性

One way, You can add the currentrowindex as a custom attribute to your textbox in RowDataBound event of the Grid. You will the index easily at this event add it as attribute. Now you can access the same attribute at javasctipt as

<asp:TextBox ID="T3" runat="server" onblur="getIndex(this);">

function getIndex(curObj)
{
    var index = curObj.getAttribute('currentrowindex ');
}

在GridView事件的ItemDataBound上你可以像这样编写

这是用于数据网格所以转换它到Gridview

On the ItemDataBound of the GridView event you can write like that
This is for data grid so convert it to Gridview

protected void DataGrid1_ItemDataBound(object sender, DataGridItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || 
                 e.Item.ItemType == ListItemType.AlternatingItem)
            {
                ((TextBox)e.Item.FindControl("txt1")).Attributes.Add("onblur", "getIndex(" +                        e.Item.ItemIndex + ")"); 
            }
        }

尝试以下操作，



OnClientClick = 返回电话（这个）



假设您的图像ctrl在项目模板中，没有其他嵌套元素存在



javascript：



函数调用（ctrl）

{

var row = ctrl.parentNode .parentNode; //获取包含图像的行

var rowIndex = row.rowIndex; //该行的行索引。

}

try the following,

OnClientClick="return Call(this)"

assuming ur image ctrl is in Item template and no other nesting elements are there

javascript:

function Call(ctrl)
{
var row=ctrl.parentNode.parentNode;//to get row containing image
var rowIndex=row.rowIndex;//row index of that row.
}
