Analysis on the principle of passing parameters when jquery refers to methods_jquery

I often go online to download js plug-ins written by experts. Every time I just need to quote js and set the variables, I have never understood the principle (mainly because the code of the experts is too concise-,-).

This time I figured out how to pass and set multiple (many) parameters.

For example, the method is function lunbo(){};

When calling and setting, write:

lunbo({

　　speed:200,

　　wrapper:'#id',

　　ease:'easing'

})

Then, when obtained within the method:

function lunbo(options){

　　var set=$.extend({},options);

　　var _speed=set.speed;

　　var _wrapper=set.wrapper;

　　var _ease=set.ease;

　　/*

　　使用获取的参数

　　*/

　　}

In addition, when there is really no other way, you can set global variables and use them flexibly.
