                  问题描述

                  我有一些单选按钮,我希望在加载页面时将其中一个设置为默认选中.我该怎么做?

                  I have some radio buttons and I want one of them to be set as selected by default when the page is loaded. How can I do that?

                  <input type="radio" name="imgsel"  value=""  /> 
                  

                  推荐答案

                  XHTML 解决方案:

                  XHTML solution:

                  <input type="radio" name="imgsel" value="" checked="checked" />
                  

                  请注意,checked 属性的实际值并不重要;这只是分配 "checked" 的约定.最重要的是,像 "true""false" 这样的字符串没有任何特殊含义.

                  Please note, that the actual value of checked attribute does not actually matter; it's just a convention to assign "checked". Most importantly, strings like "true" or "false" don't have any special meaning.

                  如果您的目标不是 XHTML 一致性,您可以将代码简化为:

                  If you don't aim for XHTML conformance, you can simplify the code to:

                  <input type="radio" name="imgsel" value="" checked>
