jQuery相当于Ruby的.send（）方法 [英] jQuery equivalent of Ruby's .send() method

问题描述

我目前正在开发一个jQuery插件，我想解雇一个元素，但是它被解雇的方式（slideUp，hide和其他jQuery方法）指定为一个选项。

I am currently developing a jQuery plugin where I would like to dismiss an element but have the way it is dismissed (slideUp, hide, and other jQuery methods) specified as an option.

例如，有人可以指定：

$('element').plugin({style: "slideUp", speed: 300});

它将在给定元素上调用slideUp。

and it will call slideUp on the given element.

这是一个简化的例子，插件会做很多事情，但我只是想知道在JavaScript / jQuery中是否有可能这样的事情。作为一个并行，我正在寻找类似于Ruby的.send（）方法的东西。

This is a simplified example and the plugin will do a lot more but I was just wondering if something like this was possible in JavaScript / jQuery. As a parallel I am looking for something much like Ruby's .send() method.

谢谢！

编辑：
我找到了这个插件它做了类似于我正在寻找的东西，但我很乐意，如果有一些方法可以做到这一点，而不包括另一个插件。

I did find this plugin which does something similar to what I am looking for but I would love if there was some way to do this without including another plugin.

推荐答案

您可以使用方括号 [] 访问javascript对象的任何成员（包括函数）然后使用正常括号调用它（）。这是一个非常简化的例子

You can access any member of a javascript object (including functions) using the square brackets [] And then call that, with the normal parenthesis (). Here's a very simplified example

​var test = {
    slide: function() {alert('slide');}​,
    fade: function() {alert('fade');}
}

var style = "slide"; // or 'fade'

test[style]();​​​​​​
