将对象发送到远程 javascript 文件

因此，如果我在我的网站上设置雅虎管道徽章，雅虎会给我这段代码，

<script src="http://pipes.yahoo.com/js/listbadge.js">{"pipe_id":"USER_ID","_btype":"list"}</script>

请注意它将对象文字传递给远程脚本。我想用我自己的脚本做类似的事情，你如何与该输入交互？

So if i am setting up a yahoo pipes badge on my site, yahoo gives me this code

<script src="http://pipes.yahoo.com/js/listbadge.js">{"pipe_id":"USER_ID","_btype":"list"}</script>

Notice its passing an object literal to the remote script.
i would like to do something similar with my own scripts, how do you interact with that input?

实际上，您无法像本机那样传递变量。雅虎正在做的是，在他们的 listbadge.js 文件中，它搜索页面上的所有

他们的来源有点混乱，但这是我对其的最好理解。

var scripts = document.getElementsByTagName("SCRIPT");

for (var i = 0; i < scripts.length; i++) {
    var includeString = scripts[i].src;
    if (includeString.match("listbadge.js")) {
        if (scripts[i].innerHTML){
            var passedVariables = parseJson(scripts[i].innerHTML);
        }
        break;
    }
}

You can't actually pass variables around like that natively. What Yahoo is doing there is that in their listbadge.js file, it searches through all the <script> tags on the page until it finds the one which included it, and then parses the innerHTML as JSON.

Their source has been slightly obfuscated, but here's my best understanding of it.

var scripts = document.getElementsByTagName("SCRIPT");

for (var i = 0; i < scripts.length; i++) {
    var includeString = scripts[i].src;
    if (includeString.match("listbadge.js")) {
        if (scripts[i].innerHTML){
            var passedVariables = parseJson(scripts[i].innerHTML);
        }
        break;
    }
}
