总结ASP.NET C#中经常用到的13个JS脚本代码

//用查询得的数据集进行绑定
if (dt.Rows.Count > 0)
{
    //绑定
    this.gv_InfoFromSendModule.DataSource = dt;
    this.gv_InfoFromSendModule.DataBind();
    //确定按钮显示
    this.btn_OK.Visible = true;
    this.txthid_RowCount.Text = dt.Rows.Count.ToString();
}
//GridView的RowDataBound
protected void gv_InfoFromSendModule_RowDataBound(object sender, GridViewRowEventArgs e)
{
   if (e.Row.RowIndex < 0)
      return;
   e.Row.Attributes.Add("onclick", "radButton('" + e.Row.RowIndex.ToString() + "','" + e.Row.Cells[1].Text.Trim() + "');");
   //RadioButton rad = (RadioButton)e.Row.Cells[0].FindControl("rad_Select");
   //rad.Attributes.Add("onclick", "radButton('"+e.Row.RowIndex.ToString()+"','"+ e.Row.Cells[1].Text.Trim()+"');");
}
//行上所绑定的JS
function radButton(rowIndex,rowGUID)
{
    //gv_InfoFromSendModule$ctl02$rad_Select
    var rowCount = parseInt(document.all.txthid_RowCount.value)+2;
    for(var i=2;i<rowCount;i++)
    {
        var tmpName;
        if(i<10)
