从applet调用JavaScript函数 [英] Calling a Javascript function from an applet

问题描述

所有我想要做的就是调用从Applet的一个JavaScript函数，并通过多个变量，我可以只用一个变量来做到这一点，但我想与多个做到这一点。

All I want to do is call a javascript function from a Applet and pass multiple variables, I'm able to do this with just one variable, but I want to do it with multiple.

这是小应用程序调用JavaScript函数并传递一个变量其中工程：

calling Javascript function from applet and passing one variable which works:

  msg = "test";
    try {
        getAppletContext().showDocument
                (new URL("javascript:UpdateComputerDetails(\"" + msg + "\")"));
    }
    catch (MalformedURLException me) { }

我如何可以传递多个变量来这个功能呢？

How Can I pass Multiple variables to this function?

推荐答案

您将简单地想用：

arg1 = "foo";
arg2 = "bar";
try {
    getAppletContext().showDocument
            (new URL("javascript:UpdateComputerDetails(\"" + arg1 + "\", \"" + arg2 + "\")"));
}
catch (MalformedURLException me) { }

在艰难的部分掌握实际上是构建URL，因为你将不得不逃避一些东西以这种或那种方式。您可以通过在JS使用单引号缓解疼痛：

The tough part to master is actually building the URL, since you'll have to escape some stuff in one way or another. You can ease the pain by using single-quotes in the JS:

"javascript:UpdateComputerDetails('" + arg1 + "', '" + arg2 + "')"

现在，你必须要小心， ARG1 和 ARG2 （如果你去多了，其他参数以及）要么不包含 （或如果您使用双引号语法），或这些你建立你的URL，然后进行正确转义。

Now, you need to be careful that arg1 and arg2 (and if you go for more, the other arguments as well) either do not contain ' (or " if you use the double-quote syntax), or these are properly escaped before you build your URL.
