如何将 html 和 javascript 从 loadContent() 加载到 webengine 中?

问题描述：

有人可以提供一些关于如何从 loadContent() 将以下内容加载到 webviewer 的建议吗?

Could someone provide some suggestions on how to load the following onto webviewer from loadContent()?

我试图做这样的事情，但它似乎不起作用.谢谢！

I was trying to do something like this, but it doesn't seem to work. Thanks!

    Scanner sc1 = new Scanner(new File("src/web/web.html"));
    String webStr = sc1.useDelimiter("\Z").next();

    Scanner sc2 = new Scanner(new File("src/web/data.js"));
    String dataStr = sc2.useDelimiter("\Z").next();

    Scanner sc3 = new Scanner(new File("src/web/cytoscape.min.js"));
    String cytoStr = sc3.useDelimiter("\Z").next();

    Scanner sc4 = new Scanner(new File("src/web/jquery.min.js"));
    String jqueryStr = sc4.useDelimiter("\Z").next();

    webEngine.loadContent(cytoStr, "text/javascript");
    webEngine.loadContent(jqueryStr, "text/javascript");
    webEngine.loadContent(dataStr, "text/javascript");
    webEngine.loadContent(webStr, "text/html");

我刚刚发现在 HTML 中使用标签也能解决问题:

I just found out that using the <base> tag in the HTML also does the trick:

<html>
    <head>
        <title>The slash at the end of the href is important!</title>
        <base href="file:///absolute/path/to/your/docroot/" />
    </head>
    <body>
        <img src="image.png"/>
    </body>
</html>

如果你通过 engine.loadContent(String) 加载上面的代码，那么 image.png 将从 /absolute/path/to/your/加载docroot/image.png.

If you load the above code via engine.loadContent(String) then image.png will be loaded from /absolute/path/to/your/docroot/image.png.

如果您需要加载多个资源，这种方法更容易，因为您只需在一个地方指定绝对路径.

This method is easier if you need to load multiple resources since you only have to specify the absolute path at a single place.

这已经用 Java 8u25 的 WebView 测试过.

This has been tested with WebView of Java 8u25.
