js 第一篇(常用交互方法)

1. cocument.write("content")  //向html 直接写入内容

2. alert("content")  // 警告对话框

3. confirm("content")  //确认对话框

3. prompt("content")  //提问对话框

4. window.open("url","窗体名","窗体打开样式")   //窗口打开

四种互动方式汇总实例:

 1 <!DOCTYPE html>
 2 <html>
 3  <head>
 4   <title> one </title>  
 5   <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>   
 6   <script type="text/javascript">  
 7   function opennewwindow(){
 8     var win = confirm("您确认打开新的网站么?");
 9     if (win == true){
10         var url = prompt("请输入您要打开的网站链接:","https://www.baidu.com/");
11         if (url != null){
12             window.open(url,"_pagetest","width=300,height=300,top=20,left=20,menubar=no,toolbar=no");
13         }else{
14             alert("您未确认打开指定网站!");
15         }
16     }else{
17         alert("您未确认打开!");
18     }
19   }
20   </script> 
21  </head>
