将Javascript变量声明为代码并重用 [英] Javascript variable declared as code and reuse

问题描述

我有一个启用了jQuery的javascript应用程序，该应用程序具有一个声明为大量代码的变量.

I have a jquery enabled javascript app that has a variable that is declared as a substantial hunk of code.

var Listings = Spine.Controller.sub({
    TPL: Handlebars.compile( $( '#entry-template' ).html() ),
    events: //stuff
    init: function() //stuff

    //a whole bunch of functions
});

我想把这段大块的代码放入一个单独的文件中(因为它长约300行)并用jquery加载它.但是更重要的是，我希望能够将此代码用于两个变量，而不必求助于复制粘贴.

I want to pull this hunk of code into a separate file (as it is about 300 lines long) and load it with jquery. However more importantly, I want to be able to use this code for two variables without resorting to copy-pasting.

推荐答案

将代码更改为此:

function giveMeAName() {
    return Spine.Controller.sub({
        // massive code here
    });
}

然后，您可以像平常一样通过jQuery包含该文件.包含之后，执行以下操作:

Then you can include that file via jQuery as you would normally. After including, do this:

var Listings = giveMeAName();
var SomethingElse = giveMeAName();

如果代码的两种用法略有不同，您也可以传递参数.

You can also pass parameters, if the two uses of the code differ slightly.
