User Control Static Name Option?

由 喜欢而已 提交于 2019-12-22 07:12:26
问题 I know there is a way to force asp web user controls (ascx) to use static ID's so they don't get appended with all the appended naming garbage...but is there way to do the same for the"name" attribute? Specifically, in this case, for DDL's? JQuery needs a specific name and I need to stop .NET from doing this. 回答1: Not possible in ASP.Net for now ... I've found this combination to be an acceptable solution. Add the ClientIDMode="Static" to the control: <asp:HiddenField ID="HiddenField1" runat=

问题 This question was originary in my head as "Can I use AWT controls in a Servlet?" , which will show all my ignorance on the subject. I am new to JAVA technologies but after a bit of reading, I seem to understand AWT controls directly hook up the OS GUI elements so there is no way to use or extend JPanels, JButtons and so forth in a Servlet to be injected in a JSP and let the browser render those controls (an alternative could probably be embedding an applet in a JSP but I don't wanna do that).
