要获取有关网页当前运行的浏览器的信息，请使用内置导航器对象。您可以对该对象使用各种 navigator 方法和属性。
示例您可以尝试运行以下代码以在 javascript 中实现 navigator 对象 -
<html> <head> <title>navigator object example</title> </head> <body> <script> <!-- var useragent = navigator.useragent; var opera = (useragent.indexof('opera') != -1); var ie = (useragent.indexof('msie') != -1); var gecko = (useragent.indexof('gecko') != -1); var netscape = (useragent.indexof('mozilla') != -1); var version = navigator.appversion; if (opera) { document.write("opera based browser"); // keep your opera specific url here. } else if (gecko) { document.write("mozilla based browser"); // keep your gecko specific url here. } else if (ie) { document.write("ie based browser"); // keep your ie specific url here. } else if (netscape) { document.write("netscape based browser"); // keep your netscape specific url here. } else { document.write("unknown browser"); } // you can include version to along with any above condition. document.write("<br /> browser version info : " + version ); //--> </script> </body></html>
以上就是javascript中navigator对象的作用是什么？的详细内容。
