使用deployJava.runApplet针对特定的元素 [英] Using deployJava.runApplet to target specific element

问题描述

经过多年的成功维护，使用好老的小程序：

After many years of successfully maintaining an applet that uses the good old:

<script src="foo.js"></script> 

嵌入Java小程序的方法，我们无法支付我们的耳朵和唱啦啦啦！了。

method of embedding a Java applet, we're unable to cover our ears and sing "La la la!" anymore.

这时候要使用：

deployJava.runApplet()

当我使用一个单击处理程序触发此方法（在这里使用上通过jQuery按钮事件侦听器，但它并不重要）：

When I fire this method using a click handler (here using an event listener on a button via jQuery, but it doesn't matter):

$('#button').click(function() {
  deployJava.runApplet(attributes, parameters, version);
});

...它抹了整个现有的文档，并与小程序来替换它。所有我需要知道的是如何针对特定的DOM元素是applet的容器​​，让我的网页不会被抹去。

...it wipes out the entire existing document and replaces it with the applet. All I need to know is how to target a specific DOM element to be the container for the applet, so that my page doesn't get wiped.

看起来这将是一个属性，我可以传递的形式目标：someElement ，其中someElement可以是一个DOM对象或元素的ID作为字符串。但很可惜，我不能为这样的属性找到文档。

It seems like it would be an attribute I could pass in the form of target: someElement where "someElement" is either a DOM object or the element's ID as a string. But alas, I can't find documentation for such an attribute.

有关被完整起见，这里是什么正在通过：

For the sake of being complete, here's what's being passed:

/*here is where I imagine there might be an applicable attribute */
var attributes = {
  name: "SomeName",
  code: "some.class",
  archive: "some.jar",
  width: 640,
  height: 400
};

var parameters = {
  someParameter: someValue
};

var version = "1.5";

我能文件撰写的一切，我需要重建的文件，但我敢肯定，你都可以想像多么可怕的这种前景似乎给我。

I can document.write everything I need to rebuild a document, but I'm sure you can all well imagine how hideous that prospect seems to me.

任何指针将大大AP preciated。

Any pointers would be greatly appreciated.

推荐答案

作为替代<一个href=\"http://stackoverflow.com/questions/13517790/using-deployjava-runapplet-to-target-specific-element?answertab=active#answer-15139480\">Christophe鲁西解决方案，您可以覆盖文件撰写运行时 deployJava.runApplet 。

As alternative to Christophe Roussy solution you may override document.write while running deployJava.runApplet.

像这样：

function docWriteWrapper(func) {
    var writeTo = document.createElement('del'),
        oldwrite = document.write,
        content = '';
    writeTo.id = "me";
    document.write = function(text) {
        content += text;
    }
    func();
    writeTo.innerHTML += content;
    document.write = oldwrite;
    document.body.appendChild(writeTo);
}

这是那么：

docWriteWrapper(function () {
    deployJava.runApplet(attributes, parameters, "1.6");
});

一个稍微有点hackish，但就像一个魅力;）

A little bit hackish but works like a charm;)
