工具函数（浏览器操作相关）

1、返回当前url

export const currentURL = () => window.location.href;

2、获取url参数（第一种）

/**

 * @param {*} name
 * @param {*} origin
   */
export function getUrlParam(name, origin = null) {
    let reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");
    let r = null;
    if (origin == null) {
        r = window.location.search.substr(1).match(reg);
    } else {
        r = origin.substr(1).match(reg);
    }
    if (r != null) return decodeURIComponent(r[2]);
    return null;
}

3、获取url参数（第二种）

 /**
     * @param {*} name
     * @param {*} origin
       */
       export function getUrlParams(name, origin = null) {
       let url = location.href;
       let temp1 = url.split('?');
       let pram = temp1[1];
       let keyValue = pram.split('&');
       let obj = {};
       for (let i = 0; i < keyValue.length; i++) {
           let item = keyValue[i].split('=');
       let key = item[0];
        let value = item[1];
        obj[key] = value;
    }
    return obj[name];

    }

4、修改url中的参数

/**
     * @param { string } paramName
     * @param { string } replaceWith
       */
       export function replaceParamVal(paramName,replaceWith) {
   var oUrl = location.href.toString();
    var re=eval('/('+ paramName+'=)([^&]*)/gi');
    location.href = oUrl.replace(re,paramName+'='+replaceWith);
    return location.href;
    }

5、删除url中指定的参数

 /**
     * @param { string } name
       */
       export function funcUrlDel(name){
       var loca =location;
       var baseUrl = loca.origin + loca.pathname + "?";
       var query = loca.search.substr(1);
       if (query.indexOf(name)>-1) {
           var obj = {};
           var arr = query.split("&");
           for (var i = 0; i < arr.length; i++) {
               arr[i] = arr[i].split("=");
               obj[arr[i][0]] = arr[i][1];
           }
           delete obj[name];
       var url = baseUrl + JSON.stringify(obj).replace(/[\"\{\}]/g,"").replace(/\:/g,"=").replace(/\,/g,"&");
        return url
    }
    }

6、获取窗口可视范围的高度

export function getClientHeight() {
    let clientHeight = 0;
    if (document.body.clientHeight && document.documentElement.clientHeight) {
        clientHeight = (document.body.clientHeight < document.documentElement.clientHeight) ? document.body.clientHeight : document.documentElement.clientHeight;
    }
    else {
        clientHeight = (document.body.clientHeight > document.documentElement.clientHeight) ? document.body.clientHeight : document.documentElement.clientHeight;
    }
    return clientHeight;
}

7、开启全屏

/**
     * @param {*} element
       */
       export function launchFullscreen(element) {
       if (element.requestFullscreen) {
           element.requestFullscreen()
       } else if (element.mozRequestFullScreen) {
           element.mozRequestFullScreen()
       } else if (element.msRequestFullscreen) {
           element.msRequestFullscreen()
   } else if (element.webkitRequestFullscreen) {
        element.webkitRequestFullScreen()
    }
    }

8、关闭全屏

export function exitFullscreen() {
    if (document.exitFullscreen) {
        document.exitFullscreen()
    } else if (document.msExitFullscreen) {
        document.msExitFullscreen()
    } else if (document.mozCancelFullScreen) {
        document.mozCancelFullScreen()
    } else if (document.webkitExitFullscreen) {
        document.webkitExitFullscreen()
    }
}

9、返回当前滚动条位置

export const getScrollPosition = (el = window) => ({
    x: el.pageXOffset !== undefined ? el.pageXOffset : el.scrollLeft,
    y: el.pageYOffset !== undefined ? el.pageYOffset : el.scrollTop
});

10、http跳转https

export const httpsRedirect = () => {
    if (location.protocol !== 'https:') location.replace('https://' + location.href.split('//')[1]);
};

11、检查页面底部是否可见

export const bottomVisible = () =>{
    return document.documentElement.clientHeight + window.scrollY >=
        (document.documentElement.scrollHeight || document.documentElement.clientHeight);
};

12、打开一个窗口

/**
     * @param { string } url
     * @param { string } windowName
     * @param { number } width
     * @param { number } height
       */
       export function openWindow(url, windowName, width, height) {
       var x = parseInt(screen.width / 2.0) - width / 2.0;
       var y = parseInt(screen.height / 2.0) - height / 2.0;
       var isMSIE = navigator.appName == "Microsoft Internet Explorer";
       if (isMSIE) {
           var p = "resizable=1,location=no,scrollbars=no,width=";
           p = p + width;
           p = p + ",height=";
           p = p + height;
           p = p + ",left=";
           p = p + x;
           p = p + ",top=";
           p = p + y;
           window.open(url, windowName, p);
       } else {
           var win = window.open(
               url,
               "ZyiisPopup",
               "top=" +
               y +
               ",left=" +
               x +
               ",scrollbars=" +
               scrollbars +
               ",dialog=yes,modal=yes,width=" +
               width +
               ",height=" +
           height +
            ",resizable=no"
        );
        eval("try { win.resizeTo(width, height); } catch(e) { }");
        win.focus();
    }
    }

13、自适应页面（rem）

 /**
     * @param { number } width
       */
       export function AutoResponse(width = 750) {
       const target = document.documentElement;
   target.clientWidth >= 600
        ? (target.style.fontSize = "80px")
        : (target.style.fontSize = target.clientWidth / width * 100 + "px");
    }

14、localStorage 存贮

/**
     * 目前对象值如果是函数 、RegExp等特殊对象存贮会被忽略
     * @param { String } key  属性
 * @param { string } value 值
    */
    export const localStorageSet = (key, value) => {
    if (typeof (value) === 'object') value = JSON.stringify(value);
    localStorage.setItem(key, value)
    };

15、localStorage 获取

/**
     * @param {String} key  属性
   */
    export const localStorageGet = (key) => {
    return localStorage.getItem(key)
    };

16、localStorage 移除

/**
     * @param {String} key  属性
   */
    export const localStorageRemove = (key) => {
    localStorage.removeItem(key)
    };

17、localStorage 存贮某一段时间失效

 /**
     * @param {String} key  属性
     * @param {*} value 存贮值
     * @param { number } expire 过期时间,毫秒数
       */
       export const localStorageSetExpire = (key, value, expire) => {
   if (typeof (value) === 'object') value = JSON.stringify(value);
    localStorage.setItem(key, value);
    setTimeout(() => {
        localStorage.removeItem(key)
    }, expire)
    };

18、sessionStorage 存贮

 /**
     * @param {String} key  属性
     * @param {*} value 值
   */
    export const sessionStorageSet = (key, value) => {
    if (typeof (value) === 'object') value = JSON.stringify(value);
    sessionStorage.setItem(key, value)
    };

19、sessionStorage 获取

 /**
     * @param {String} key  属性
   */
    export const sessionStorageGet = (key) => {
    return sessionStorage.getItem(key)
    };

20、sessionStorage 删除

 /**
     * @param {String} key  属性
   */
    export const sessionStorageRemove = (key) => {
    sessionStorage.removeItem(key)
    };

21、sessionStorage 存贮某一段时间失效

/**
     * @param {String} key  属性
     * @param {*} value 存贮值
     * @param {String} expire 过期时间,毫秒数
       */
       export const sessionStorageSetExpire = (key, value, expire) => {
   if (typeof (value) === 'object') value = JSON.stringify(value);
    sessionStorage.setItem(key, value);
    setTimeout(() => {
        sessionStorage.removeItem(key)
    }, expire)
    };

22、cookie 存贮

 /**
     * @param {String} key  属性
     * @param {*} value  值
     * @param { String } expire  过期时间,单位天
   */
    export const cookieSet = (key, value, expire) => {
    const d = new Date();
    d.setDate(d.getDate() + expire);
    document.cookie = `${key}=${value};expires=${d.toUTCString()}`
    };

23、cookie 获取

 /**
     * @param {String} key  属性
       */
       export const cookieGet = (key) => {
       const cookieStr = unescape(document.cookie);
       const arr = cookieStr.split('; ');
       let cookieValue = '';
       for (let i = 0; i < arr.length; i++) {
           const temp = arr[i].split('=');
           if (temp[0] === key) {
               cookieValue = temp[1];
               break
       }
    }
    return cookieValue
    };

24、cookie 删除

 /**
     * @param {String} key  属性
   */
    export const cookieRemove = (key) => {
    document.cookie = `${encodeURIComponent(key)}=;expires=${new Date()}`
    };
