JavaScript提供了三个很不错的对话框函数,使用这三个函数可以很方便的显示一个对话框;
一、alert();
<script type="text/javascript"> alert("你好,"+' '+"这是第二行内容"); </script>
二、prompt();
<script type="text/javascript"> function disp_prompt(){ var name= prompt("Please enter you name","Aqua"); if(name!=null && name!=""){ document.write("Hello "+name+" !How are you today?"); } } </script> <input type="button" onclick="disp_prompt()" value="单击来看看有什么" />
三、confirm()
<script type= "text/javascript"> function disp_confirm(){ var r = confirm("Press a Button"); if(r == true){ document.write("You Processed OK"); }else{ document.write("You Process Cancel"); } } </script> <input type="button" onclick="disp_confirm()" value ="显示窗口来看看" />
