js常用代码整理-CavinHuangのBlog-http://blog.zukmb.cn

1. PC - js

返回指定范围的随机数(m-n之间)的公式
```
Math.random()*(n-m)+m
```
return false

// event.preventDefault()会阻挡预设要发生的事件.
// event.stopPropagation()会阻挡发生冒泡事件.
// 而return false则是前面两者的事情他都会做：
// 他会做event.preventDefault();
// 他会做event.stopPropagation();
// 停止callback function的执行并且立即return回来

防止被Iframe嵌套

if(top != self)&#123;
  location.href = ”about:blank”;
&#125;

两种图片lazy加载的方式
第一个By JS中级交流群成都-猎巫第二个By 上海-zenki

// @description 准备为图片预加载使用的插件
// 使用的图片容器css类名为lazy-load-wrap
// 图片真实地址为data-lazy-src
// 当lazy-load-wrap容器进入视口，则开始替换容器内所有需要延迟加载的图片路径，并更改容器的加载状态
//第一种方法
$.fn.compassLazyLoad=function()&#123;
  var _HEIGHT=window.innerHeight,
  _lazyLoadWrap=$('.lazy-load-wrap');

  var methods=&#123;
      setOffsetTop:function()&#123;
          $.each(_lazyLoadWrap,function(i,n)&#123;
              $(n).attr(&#123;
                  'top':n.offsetTop-_HEIGHT,
                  'status':'wait'
              &#125;);
          &#125;)
      &#125;,
      isShow:function()&#123;
          var _scrollTop=$(window).scrollTop;
          //利用image容器判断是否进入视口，而非image本身
          $.each(_lazyLoadWrap,function()&#123;
              var _that=$(this);
              if (_that.attr('status')==='done') &#123;
                  return;
              &#125;;
              if (_that.attr('top')<=_scrollTop) &#123;
                  _that.find('img[data-lazy-src]').each(function(i,n)&#123;
                      n.src=$(n).data('lazy-src');
                  &#125;);
                  _that.attr('status','done');
              &#125;;
          &#125;)
      &#125;,
      scroll:function()&#123;
          $(window).on('scroll',function()&#123;
              methods.isShow();
          &#125;);
      &#125;,
      init:function()&#123;
          methods.setOffsetTop();
          methods.isShow();
          methods.scroll();
      &#125;
  &#125;;
  methods.init();

}

//第二种方法

var exist=(function($){
var timer=null,
temp=[].slice.call($(‘.container’));
ret={};

for(var i=0,len=temp.length-1;i<=len;i++){
    ret[i]=temp[i];
}
var isExist=function(winTop,winEnd){
    for(var i in ret){
        console.log(ret);
        var item=ret[i],
        eleTop=item.offsetTop,
        eleEnd=eleTop+item.offsetHeight;

        if((eleTop>winTop&&eleTop<=winEnd)||(eleEnd>winTop&&eleEnd<=winEnd)){
            $(item).css('background','none');
            new Tab($(item).attr('id'),data).init;
            delete ret[i];
        }
    }
}
return {
    timer:timer;
    isExist:isExist;
};

})($);

//第三种方法
Zepto(function ($) {
var swiper = new Swiper(‘.swiper-container’, {
pagination: ‘.swiper-pagination’,
paginationClickable: true,
autoplay: 3000,
loop: true,
autoplayDisableOnInteraction: false
});
(function lazyLoad() {
var imgs = $(“.lazyLoad”);
var src = ‘’;
$.each(imgs, function (index, item) {
src = $(item).attr(‘data-src’);
$(item).attr(‘src’, src);
});
})();
});
$(function () {
var lazyLoadTimerId = null;
/// 智能加载事件
$(window).bind(“scroll”, function () {
clearTimeout(lazyLoadTimerId);
lazyLoadTimerId = setTimeout(function () {
// 延迟加载所有图片
var isHttp = (location.protocol === “http:”);
$(“#ym_images img”).each(function () {
var self = $(this);
if (self.filter(“:above-the-fold”).length > 0) {
var originUrl = self.attr(“data-original”);
self.attr(“src”, originUrl);
}
});
}, 500);
});
});


- 某年某月的1号为星期几
```javascript
var weekday = ["星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六"];
weekday[new Date(2015, 9, 1).getDay()];    //2015年10月1号

2. Mobile - js

js 判断IOS, 安卓

var u = navigator.userAgent, app = navigator.appVersion;
var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Linux') > -1; //android终端或者uc浏览器
var isiOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/); //ios终端
alert('是否是Android：'+isAndroid);
alert('是否是iOS：'+isiOS);

3. 微信 weixin

UserAgent 判断微信客户端

// Mozilla/5.0 (iPhone; CPU iPhone OS 8_3 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko) Mobile/12F70 MicroMessenger/6.1.5 NetType/WIFI
function isWechat() &#123;  
  var ua = navigator.userAgent.toLowerCase();
  return /micromessenger/i.test(ua) || /windows phone/i.test(ua);
&#125;

JS接口安全域名不填写，分享onMenuShareAppMessage直接会取默认值。
```
// 分享onMenuShareAppMessage直接会取默认值
```
关闭当前页面
```
WeixinJSBridge.call('closeWindow');
```

支付接口方法调用必须在addevent里边调用

document.addEventListener('WeixinJSBridgeReady', function onBridgeReady()&#123;
  that.initOrder();
&#125;, false);

支付接口方法调用必须在

WeixinJSBridge.invoke('getBrandWCPayRequest', d, function(res)&#123;
  if(res.err_msg == "get_brand_wcpay_request:ok")&#123;
      // alert("支付成功");
      // union.release(d.orderId);
      resetUrl();
      paySuccess('home', d.orderId);
  &#125; else &#123;
      cancelOrder(d.orderId);
      // alert(res.err_msg);
  &#125;
  loading.hide();
&#125;);

瀑布流无限加载实例

// be dependent on jquery & jquery.infinitescroll.min.js
// insert this '<div id="more"><a href="api?page="></a></div>' to your page.html
(function($)&#123;
$(function()&#123;
    var $container = $('.list-wrap-gd');
    function layOutCallBack() &#123;
        $container.imagesLoaded(function()&#123;
            $container.masonry(&#123;
                itemSelector: '.item-bar',
                gutter: 10
            &#125;);
        &#125;);
        $container.imagesLoaded().progress( function() &#123;
            $container.masonry('layout');
        &#125;);
    &#125;

    layOutCallBack();

    $container.infinitescroll(&#123;
        navSelector : "#more",
        nextSelector : "#more a",
        itemSelector : ".item-bar",
        pixelsFromNavToBottom: 300,
        loading:&#123;
            img: "/images/masonry_loading.gif",
            msgText: ' ',
            finishedMsg: "<em>已经到最后一页</em>",
            finished: function()&#123;
                $("#more").remove();
                $("#infscr-loading").hide();
            &#125;
        &#125;,
        errorCallback:function()&#123;
            $(window).unbind('.infscr');
        &#125;,
        pathParse: function (path, nextPage) &#123;
            var query = "";
            var keyword=$("#search_keyword").val();
            var cat_id=$("#cat_id").val();
            var brand_id=$("#brand_id").val();
            var country_id = $("#country_id").val();
            query = query + "&namekeyword="+keyword;
            query = query +"&cat_id="+cat_id
            query = query + "&brand_id=" + brand_id;
            query = query + "&country_id=" + country_id;
            path = [path,query];
            return path;

iOS，Safari浏览器，input等表单focus后fixed元素错位问题

if( /iPhone|iPod|iPad/i.test(navigator.userAgent) ) &#123;
$(document).on('focus', 'input, textarea', function()
&#123;
   $('header').css("position", 'absolute');
   $('footer').css("position", 'absolute');

&#125;);

$(document).on('blur', 'input, textarea', function()
&#123;
     $('header').css("position", 'fixed');
     $('footer').css("position", 'fixed');

&#125;);
&#125;


- 得到地理位置
```javascript
function getLocation(callback){
  if(navigator.geolocation){
      navigator.geolocation.getCurrentPosition(
              function(p){
                  callback(p.coords.latitude, p.coords.longitude);
              },
              function(e){
                  var msg = e.code + "\n" + e.message;
              }
      );
  }
}

rem计算适配

(function(doc, win)&#123;
var docEl = doc.documentElement,
    resizeEvt = 'orientationchange' in window ? 'orientationchange' : 'resize',
    recalc = function()&#123;
        var clientWidth = docEl.clientWidth;
        if(!clientWidth) return;
        docEl.style.fontSize = 20 * (clientWidth / 320) + 'px';
    &#125;;

if(!doc.addEventListener) return;
win.addEventListener(resizeEvt, recalc, false);
doc.addEventListener('DOMContentLoaded', recalc, false);
&#125;)(document, window);

另外一种rem方案

var dpr, rem, scale;
var docEl = document.documentElement;
var fontEl = document.createElement('style');
var metaEl = document.querySelector('meta[name="viewport"]');

dpr = window.devicePixelRatio || 1;
rem = docEl.clientWidth * 2 / 10;
scale = 1 / dpr;

// 设置viewport，进行缩放，达到高清效果
metaEl.setAttribute(‘content’, ‘width=’ + dpr * docEl.clientWidth + ‘,initial-scale=’ + scale + ‘,maximum-scale=’ + scale + ‘, minimum-scale=’ + scale + ‘,user-scalable=no’);

// 设置data-dpr属性，留作的css hack之用
docEl.setAttribute(‘data-dpr’, dpr);

// 动态写入样式
docEl.firstElementChild.appendChild(fontEl);
fontEl.innerHTML = ‘html{font-size:’ + rem + ‘px!important;}’;

// 给js调用的，某一dpr下rem和px之间的转换函数
window.rem2px = function(v) {
v = parseFloat(v);
return v * rem;
};
window.px2rem = function(v) {
v = parseFloat(v);
return v / rem;
};

window.dpr = dpr;
window.rem = rem;


- 获取js所在路径
```js
function getJsDir (src) {
    var script = null;

    if (src) {
        script = [].filter.call(document.scripts, function (v) {
            return v.src.indexOf(src) !== -1;
        })[0];
    } else {
        script = document.scripts[document.scripts.length - 1];
    }

    return script ? script.src.substr(0, script.src.lastIndexOf('/')) : script;
}

从全局捕获错误

window.onerror = function (errMsg, scriptURI, lineNumber, columnNumber, errorObj) &#123;
  setTimeout(function () &#123;
      var rst = &#123;
          "错误信息：": errMsg,
          "出错文件：": scriptURI,
          "出错行号：": lineNumber,
          "出错列号：": columnNumber,
          "错误详情：": errorObj
      &#125;;

      alert(JSON.stringify(rst, null, 10));
  &#125;);
&#125;;

如何通过 js 修改微信浏览器的title?

var $body = $('body');
document.title = 'title'; // hack在微信等webview中无法修改document.title的情况    
var $iframe = $('<iframe src="/favicon.ico"></iframe>').on('load', function()&#123;
  setTimeout(function()&#123;
      $iframe.off('load').remove()
  &#125;, 0)
&#125;).appendTo($body)

获得URL中GET参数值

// 用法：如果地址是 test.htm?t1=1&t2=2&t3=3, 那么能取得：GET["t1"], GET["t2"], GET["t3"]
function get_get()&#123;
  querystr = window.location.href.split("?")

            GET[key] = tmp_arr[1]
      &#125;
  &#125;
  return querystr[1];
&#125;

数组去重

String.prototype.unique=function()&#123;
  var x=this.split(/[\r\n]+/);
  var y='';
  for(var i=0;i<x.length;i++)&#123;
      if(!new RegExp("^"+x.replace(/([^\w])/ig,"\\$1")+"$","igm").test(y))&#123;
          y+=x+"\r\n"
      &#125;
  &#125;
  return y
&#125;;

按字典顺序，对每行进行数组排序

function SetSort()&#123;
  var text=K1.value.split(/[\r\n]/).sort().join("\r\n");//顺序
  var test=K1.value.split(/[\r\n]/).sort().reverse().join("\r\n");//反序
  K1.value=K1.value!=text?text:test;
&#125;

字符串反序输出

function IsReverse(text)&#123;
  return text.split('').reverse().join('');
&#125;
