javascript JxBrowser LoadURL/LoadHTML
从本地目录加载html文件时，JxBrowser出现问题。我在我的项目中使用了loadHTML和loadURL。在下面的实例中，当我在browserInvokeAndWait方法中使用loadURL时，我发现它花费的时间太长，无法根据需要引用我的Javascript库。我试图在我加载的页面中启用按钮，但是我无法访问任何加载的元素，因为页面本身无法加载。代码如下： 包src。爪哇

我不太明白为什么loadURL需要这么长时间，当我尝试loadHTML技术时，我发现这不起作用。关于这两种方法之间的区别，我遗漏了一些非常基本的东西
