为DataGrid模板列(以input为例)增加JS事件

    HtmlInputText JSDJ = (HtmlInputText)(this.dgBLMX.Items[i].FindControl("JSDJ"));
     JSDJ.Value=dt.Rows[i]["JSDJ"].ToString();
     ((HtmlInputText)(this.dgBLMX.Items[i].FindControl("SBSL"))).Attributes.Add("onfocus","this.select();");//获取焦点时选中
     
     ((HtmlInputText)(this.dgBLMX.Items[i].FindControl("SBSL"))).Attributes.Add("onblur","JiSuan("+i.ToString()+");");//失去焦点时计算
