查找SWT浏览器的浏览器类型/版本 [英] Find browser type/version of SWT Browser

问题描述

我遇到了Eclipse SWT浏览器无法在一台机器上加载某些样式的问题.我希望机器将IE 10用作本机浏览器，但是我不确定如何确认这一点.有没有办法确定SWT决定使用其加载页面的浏览器的类型/版本?

I am having problems with an Eclipse SWT Browser not loading certain styles on one machine. I am expecting the machine to use IE 10 as the native browser but I am not sure how I can confirm this. Is there a way to determine the type/version of the Browser which SWT decides to load the page using?

如何检测浏览器的版本?

您可以执行以下操作:

public static void main(String[] args)
{
    final Display display = new Display();
    final Shell shell = new Shell(display);
    shell.setText("Stackoverflow");
    shell.setLayout(new FillLayout());

    Browser browser = new Browser(shell, SWT.NONE);

    browser.addProgressListener(new ProgressListener()
    {
        @Override
        public void changed(ProgressEvent progressEvent)
        {
        }

        @Override
        public void completed(ProgressEvent progressEvent)
        {
            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(' ');"));
        }
    });
    browser.setUrl("https://www.google.co.uk");

    shell.pack();
    shell.open();

    while (!shell.isDisposed())
    {
        if (!display.readAndDispatch())
            display.sleep();
    }
    display.dispose();
}

在我的情况下它输出IE 11.
