如何在动态ID中查找文本框值 [英] How find textbox value in throgh dynamic id

问题描述

TextBox tb = new TextBox();
                    //tb.ID = "TextBoxCol_" + i + "Col_" + j;
                    tb.ID = "TextBoxCol_" + i;
                    cell.Controls.Add(tb);
                    row.Cells.Add(cell);
TextBox txtBox = (TextBox)Page.FindControl("ctl00_TextBoxCol_0");

"ctl00_TextBoxCol_0"是通过此ID动态生成的ID，找不到该文本框值.

"ctl00_TextBoxCol_0" this is dynamic generated id through this id not find the textbox value

推荐答案

''ctl00_TextBoxCol_0''这是clientID，您可以通过clientId处理javascript.

而是使用

''ctl00_TextBoxCol_0'' this is clientID you can handle control through clientId in javascript.

Instead use

TextBox txtBox = (TextBox)Page.FindControl("TextBoxCol_0");

即使您可以修复您的ClientID.检查此链接 [ ^ ]

对于通过javascript查找任何asp.net控件，请使用

Hi,

Even you can fix your ClientID. Check this link[^]

And for finding any asp.net control through javascript use

var txtdate1 = document.getElementById('<%=txtdate1.ClientID%>');

希望这对您有帮助，

谢谢
