在访问ASP控件时遇到问题 [英] Having problems getting access to ASP Controls

问题描述

很抱歉，这是一个愚蠢的基本问题.但是我真的不知道如何解决这个问题.我有ASP控件(一个文本框和一个下拉列表).现在，我需要访问TextBox的value属性以及下拉列表的SelectedIndex属性.这应该很简单:
用于TextBox:

Sorry for the basic silly question. But I really dont have any idea on solving this. I have ASP controls (One Text Box and One Drop Down List). Now I need to access value property of TextBox as well as SelectedIndex property of dropdown list. This should be as simple as:
for TextBox:

document.getElementById("<%= myControlID %>").value

用于下拉列表:

for DropDown List:

document.getElementById("<%= myControlID %>").selectedindex

但是在Visual Studio 2008中，当我编写这些代码时，它不起作用.我找不到相应控件的任何value或selectedindex属性.我不明白这一点，因为在大多数论坛和教程中，它们都是以我提到的简单方式提出的.

还有其他方法吗，或者我只是在这里想念什么?请帮帮我.在此先感谢

But in Visual Studio 2008, while I am writing these codes, it does not work. I can not find any value or selectedindex attribute for the respective control. I am not getting this, because in most forums and tutorials, they suggested in a simple way I mentioned.

Is there any other way or I am just missing something here? Please help me out. Thanks in advance

推荐答案

尝试一下，我认为我们使用的是单个Cote(即'''')或double(")
document.getElementById(''<％= myControlID％>'').value

try this i think we used single cote(ie '' '') either double (" ")
document.getElementById(''<%= myControlID %>'').value
