要獲取有關網頁目前運行的瀏覽器的信息,請使用內建導航器物件。您可以對該物件使用各種 Navigator 方法和屬性。
您可以嘗試執行以下程式碼以在 JavaScript 中實作 Navigator 物件 -
<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>
