如何计算行数在GridView控件在JavaScript？ [英] how to count number of rows in gridview in javascript?

问题描述

由于这个问题说，我希望通过JS来计数的GridView的行数。我做的是做的方式<一个href=\"http://stackoverflow.com/questions/1763641/asp-net-gridview-row-count-using-javascript\">here但就是不来正确。

As the question says, i wish to count the number of rows in gridview via JS. I am doing the way it is done here but that is not coming up correctly.

我也尝试不同的方式：

 1. var rowscount = document.getElementByID('<%=Gridview1.ClientID%>').rows.length; 
 2. var rowscount = document.getElementByID("<%=Gridview1.ClientID%>").rows.length; 
 3. var rowscount = document.getElementByID('<%#Gridview1.ClientID%>').rows.length;
 4. var rowscount = document.getElementByID("<%#Gridview1.ClientID%>").rows.length;    
 5. var rowscount = document.getElementByID("Gridview1.ClientID").rows.length;
 6. var rowscount = document.getElementByID("Gridview1").rows.length;  

更新：忘了提：我的gridview的是里面的UpdatePanel。请问这有什么区别？
什么是正确的说法？

UPDATE : Forgot to Mention: My gridview is inside updatepanel. Would that make any difference? What is the right statement?

推荐答案

找到了原因：由于电网是包含在内容页中，JavaScript必须被列入表单标签。它运行良好！感谢所有的投入！

Found the reason: Because the grid is included in content page, the javascript had to be included under form tag. It runs well! Thanks all for inputs!!
