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]();​​​​​​
