Edit The code seems to run fine in the latest stable version of chrome, so this might just be a bug in the canary version. 编辑该代码在chrome的最新稳定版本中似乎可以正常运行，因此这可能只是canary版本中的错误。

There is only a problem with chrome when running the html (and jar) locally. 在本地运行html（和jar）时，chrome仅存在问题。

Answer 2

Enable java in chrome, to do this, type javascript:if(browser.value.getIndex("chrome"){chrome.browser.enableFeature(JApplet)}); 在chrome中启用Java，为此，请键入javascript：if（browser.value.getIndex（“ chrome”）{chrome.browser.enableFeature（JApplet）}）; in to chrome 镀铬
