问题描述
如果安装了多个浏览器,如何判断 SWT 浏览器使用的是哪个操作系统浏览器?
我特别询问 Windows 和 OSX。
解决方法
使用 browser.getBrowserType()
方法。见:https://help.eclipse.org/2020-12/topic/org.eclipse.platform.doc.isv/reference/api/org/eclipse/swt/browser/Browser.html#getBrowserType()
// ... your code
final var browser = new Browser(shell,SWT.NONE);
browser.setUrl("https://www.google.com/");
/**
* Description: Returns the type of native browser being used by this instance. Examples:
* "ie","mozilla","voyager","webkit"
*/
System.out.println(browser.getBrowserType());
或
JS 解决方案:Find browser type/version of SWT Browser
// ... your code
final var browser = new Browser(shell,SWT.NONE);
browser.setUrl("https://www.google.com/");
System.out.println(browser.evaluate("var ua = navigator.userAgent,tem,M = ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\\/))\\/?\\s*(\\d+)/i) || []; if (/trident/i.test(M[1])) { tem = /\\brv[ :]+(\\d+)/g.exec(ua) || []; return 'IE ' + (tem[1] || ''); } if (M[1] === 'Chrome') { tem = ua.match(/\\b(OPR|Edge)\\/(\\d+)/); if (tem != null) return tem.slice(1).join(' ').replace('OPR','Opera'); } M = M[2] ? [M[1],M[2]] : [navigator.appName,navigator.appVersion,'-?']; if ((tem = ua.match(/version\\/(\\d+)/i)) != null) M.splice(1,1,tem[1]); return M.join(' ');"));
