现在我的问题是---保存时检查数据是否在 3个网格中.

例如:
我从 To 插入记录，但是我没有向 Cc，Bcc 插入记录，然后显示错误输入至少一条记录..." .为此，我编写了Script函数，并使用 OnClientClick 属性调用Script in Save按钮.但是我没有得到，

            if (To.rows.length < 1 || Cc.rows.length < 1 || Bcc.rows.legth < 1) {
                alert("please enter at least one record");

        }

但是我没有完全满足我的要求.请帮助我做到这一点.

推荐答案

它不是非常紧急".免费从事工作的人希望提供帮助，但实际上并不在乎您是否无法完成工作.

在我看来，只要您将gridview呈现为表格，它就应该可以工作.我不清楚您为什么需要这样做，请确定您在回发期间是否知道网格的数据源中是否包含任何数据?无论哪种方式，这对我来说都是一团糟，还不清楚但是我没有完全满足我的要求"是什么意思.您是否已浏览Chrome中的js?怎么了 ?

It''s not ''very urgent''. The people doing your job for free want to help, but don''t actually care if you can''t do your job.

This looks to me like it should work, so long as your gridview is rendered as a table. I am unclear why you need to do it this way, surely you know during a postback if your data source for the grid had any data in it ? Either way, this looks messy to me, and it''s unclear what ''but i''m not getting my requirement exactly'' means. Have you stepped through the js in Chrome ? What is happening ? How is it not behaving like you expect ?

试试这个:

Hi,
Try this:

function Validate() {
    var To = document.getElementByID(<%=gvTo.ClientID%>).rows.length;
    var Cc = document.getElementByID(<%=gvCc.ClientID%>).rows.length;
    var Bcc = document.getElementByID(<%=gvBcc.ClientID%>).rows.length;

    if (To < 1 || Cc < 1 || Bcc < 1) {
        alert("please enter at least one record");
    }
    else {
        alert("Continue..");
    }
}
