使用selected属性来指定在html页面加载时应预先选择该选项。您可以尝试运行以下代码来实现selected属性 −
示例<!doctype html><html> <head> <title>html selected attribute</title> </head> <body> <p>here's the list of subjects. select any one:</p> <form> <select name = "dropdown"> <option value = "computer architecture" selected>computer architecture</option> <option value = "java">java</option> <option value = "discrete mathematics">discrete mathematics</option> </select> </form> </body></html>
以上就是在html中如何指定选项在页面加载时应预先选中？的详细内容。
