JavaScript工具库MyTools详解

本文实例为大家分享了Javascript工具库MyTools，不断填充中，供大家参考，具体内容如下

MyTools.js

将功能绑定在window中，调用的时候，直接使用myToos.xxx就可以进行函数调用。

(function (w) {
 w.myTool = {
  
  $: function (id) {
   return typeof id === 'string' ? document.getElementById(id) : null;
  },

  
  scroll: function() {
   if(window.pageYOffset !== null){ // 最新的浏览器
    return {
     "top": window.pageYOffset,
     "left": window.pageXOffset
    }
   }else if(document.compatMode === 'CSS1Compat'){ // W3C
    return {
     "top": document.documentElement.scrollTop,
     "left": document.documentElement.scrollLeft
    }
   }
   return {
    "top": document.body.scrollTop,
    "left": document.body.scrollLeft
   }
  },

  
  client: function() {
   if(window.innerWidth !== null){ // 最新的浏览器
    return {
     "width": window.innerWidth,
     "height": window.innerHeight
