我需要在 警报 框中更改“确定”按钮的样式。
<head> <script type="text/javascript"> function show_alert() { alert("Hello! I am an alert box!"); } </script> </head> <body> <input type="button" onclick="show_alert()" value="Show alert box" /> </body>
警报框是系统对象,不受CSS约束。为此,您需要创建一个HTML元素并模仿其alert()功能。jQueryUIDialogue为您做了很多工作,基本上就像我描述的那样:Link。
alert()
