问题描述

你好，

我有一个包含4个向导步骤的向导控件，在这些向导步骤中有一些文本框，我无法使用javascript获取这些文本框的ID.

有任何建议.

推荐答案

您应该使用控件ClientIdMode ="Static"，以便可以通过使用document.getElementById()
来调用这些控件.

Hi,

You should use for the control ClientIdMode = "Static" so you can call those controls by using document.getElementById()

如果您使用的是ASP.NET 4，请参阅答案一.否则，您必须从控件获取到JS的ClientId.

If you are using ASP.NET 4 see answer one. Otherwise you have to obtain ClientId from control to JS.

document.getElementById('<%=control.ClientId%>');

由于将HTML，JS和C#混合使用，效果不是很好.如果您可以迁移到从未使用过的ASP版本，则仅为此迁移就可以节省维护代码的麻烦.

Not very nice since mixing HTML, JS and C#. If you could migrate to never version of ASP, migrate just for this it will save you some pain in maintaining code.
