常用的JavaScript WEB操作方法分享

前端之家收集整理的这篇文章主要介绍了常用的JavaScript WEB操作方法分享前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

数组方法

方法 // index,返回位置! 不存在则返回 -1; index: function (t,arr) { //# 返回当前值所在数组的位置 if (arr.indexOf) { return arr.indexOf(t); } for (var i = arr.length ; i--;) { if (arr[i] === t) { return i * 1; } }; return -1; } //返回对象 的 键值! 返回值 类型为数组。,getKey: function (data) { //# 返回对象所有的键值 var arr = [],k ; for (k in data) { arr.push(k); }; return arr; } //从数组中 随机取出 一个值,random: function (arrays) { //# 从数组中 随机取出 一个值 arrays = arrays || []; var len = arrays.length,index = Tydic.math.randInt(0,len - 1) ; return arrays[index] || ''; } // 一维 数组去重,unique: function (array) { //#一维数组去重 array = array || []; for (var i = 0,len = array.length; i < len; i++) { for (var j = i + 1; j < array.length; j++) { if (array[i] === array[j]) { array.splice(j,1); j--; } } } return array; } // max,数组中最大的项,max: function (array) {//#求数组中最大的项 return Math.max.apply(null,array); } // min,数组中最小的项,min: function (array) { //#求数组中最小的项 return Math.min.apply(null,array); } // remove , 移除,remove: function (array,value) { //#移除数组中某值 var length = array.length; while (length--) { if (value === array[length]) { array.splice(length,1); } } return array; } //清空数组,empty: function (array) { //# 清空数组 (array || []).length = 0; return array; } // removeAt ,删除指定位置的 值 //@index,索引. 不传递 index ,会删除第一个,removeAt: function (array,index) { //#删除数组中 指定位置的值 array.splice(index,1); return array; } //打乱数组排序,shuffle: function (arr) { //#打乱数组排序 var array = (arr || []).concat(),length = array.length,i = length //遍历,tmp = null // 临时,rand = Tydic.math.randInt //位置,pos = 0 ; while (i--) { pos = rand(0,length); //交换随机位置 tmp = array[pos]; array[pos] = array[i]; array[i] = tmp; } return array; } };

cookie方法

支持 cookie enable: !!navigator.cookieEnabled //读取COOKIE,get: function (name) { //#读取 cookie var reg = new RegExp("(^| )" + name + "(?:=([^;]*))?(;|$)"),val = document.cookie.match(reg) ; return val ? (val[2] ? unescape(val[2]) : "") : ''; } //写入COOKIES,set: function (name,value,expires,path,domain,secure) { //# 写入 cookie var exp = new Date(),expires = arguments[2] || null,path = arguments[3] || "/",domain = arguments[4] || null,secure = arguments[5] || false ; expires ? exp.setMinutes(exp.getMinutes() + parseInt(expires)) : ""; document.cookie = name + '=' + escape(value) + (expires ? ';expires=' + exp.toGMTString() : '') + (path ? ';path=' + path : '') + (domain ? ';domain=' + domain : '') + (secure ? ';secure' : ''); } //删除cookie,del: function (name,secure) { //#删除 cookie var value = $getCookie(name); if (value != null) { var exp = new Date(); exp.setMinutes(exp.getMinutes() - 1000); path = path || "/"; document.cookie = name + '=;expires=' + exp.toGMTString() + (path ? ';path=' + path : '') + (domain ? ';domain=' + domain : '') + (secure ? ';secure' : ''); } } };

url方法

当前页面的url中取 getQuery: function (name,url) { var u = arguments[1] || window.location.search,reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)"),r = u.substr(u.indexOf("?") + 1).match(reg) ; return r != null ? r[2] : ""; },getHash: function (name,url) { //# 获取 hash值 var u = arguments[1] || location.hash; var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)"); var r = u.substr(u.indexOf("#") + 1).match(reg); if (r != null) { return r[2]; } return ""; },parse: function (url) { //# 解析URL var a = document.createElement('a'); url = url || document.location.href; a.href = url; return { source: url,protocol: a.protocol.replace(':',''),host: a.hostname,port: a.port,query: a.search,file: (a.pathname.match(/([^\/?#]+)$/i) || [,''])[1],hash: a.hash.replace('#',path: a.pathname.replace(/^([^\/])/,'/$1'),relative: (a.href.match(/tps?:\/\/[^\/]+(.+)/) || [,segments: a.pathname.replace(/^\//,'').split('/') }; } };

正则表达式方法

用户 年月日,nowDate = 0 //当前年月日 ; allowAge = parseFloat(allowAge) || 18; now = typeof now == 'string' ? new Date(now) : (now || new Date());
if (!this.isIdCard(id)) {
  return false;
}
//15位身份证
if (15 == id.length) {
  age = '19' + id.slice(6,6);
} else {
  age = id.slice(6,14);
}
// 类型转换 整型
age = ~~age;
nowDate = ~~(Tydic.date.format('YYYYMMDD',now));
//比较年龄
if (nowDate - age < allowAge * 1e4) {
  return false;
}
return true;

}
//浮点数,isFloat: function (num) { //# 是否为 浮点数
return /^(([1-9]\d)|(\d+.\d+)|0)$/.test(num);
}
//正整数,isInt: function (num) { //# 是否为 正整数
return /^[1-9]\d
$/.test(num);
}
//是否全为汉字,isChinese: function (str) { //# 是否全为 汉字
return /^([\u4E00-\u9FA5]|[\uFE30-\uFFA0])+$/gi.test(str);
}

};

字符串方法

': ">",' ': "",'\t': " ",'(': "(",')': ")",'*': "*",'+': "+",',': ",",'-': "-",'.': ".",'/': "/",'?': "?",'\\': "\",'\n': "
" }); } //重复字符串,repeat: function (word,length,end) { //# 重复字符串 end = end || ''; //加在末位 length = ~~length; return new Array(length * 1 + 1).join(word) + '' + end; } //增加前缀,addPre: function (pre,word,size) { //# 补齐。如给数字前 加 0 pre = pre || '0'; size = parseInt(size) || 0; word = String(word || ''); var length = Math.max(0,size - word.length); return this.repeat(pre,word); } //去除两边空格,trim: function (text) { //# 去除两边空格 return (text || '').replace(/^\s+|\s$/,''); } //字符串替换,replace: function (str,re) { //# 字符串替换 str = str || ''; for (var key in re) { replace(key,re[key]); }; function replace(a,b) { var arr = str.split(a); str = arr.join(b); }; return str; },xss: function (str,type) { //# XSS 转义 //空过滤 if (!str) { return str === 0 ? "0" : ""; } switch (type) { case "html": //过滤html字符串中的XSS return str.replace(/[&'"<>\/\\\-\x00-\x09\x0b-\x0c\x1f\x80-\xff]/g,function (r) { return "&#" + r.charCodeAt(0) + ";" }).replace(/ /g,"").replace(/\r\n/g,"
").replace(/\n/g,"
").replace(/\r/g,"
"); break; case "htmlEp": //过滤DOM节点属性中的XSS return str.replace(/[&'"<>\/\\\-\x00-\x1f\x80-\xff]/g,function (r) { return "&#" + r.charCodeAt(0) + ";" }); break; case "url": //过滤url return escape(str).replace(/\+/g,"%2B"); break; case "miniUrl": return str.replace(/%/g,"%25"); break; case "script": return str.replace(/[\\"']/g,function (r) { return "\\" + r; }).replace(/%/g,"\\x25").replace(/\n/g,"\\n").replace(/\r/g,"\\r").replace(/\x01/g,"\\x01"); break; case "reg": return str.replace(/[\\\^\$\*\+\?\{\}\.\(\)\[\]]/g,function (a) { return "\\" + a; }); break; default: return escape(str).replace(/[&'"<>\/\\\-\x00-\x09\x0b-\x0c\x1f\x80-\xff]/g,"
"); break; } } // badword,过滤敏感词 //@text : 要过滤的文本,类型 :字符串 //@words : 敏感词 ,类型,数组,如 : ['你妹','我丢','我靠'] // 如果 用 正则匹配, text 长度 100万,words 100万,需要 4秒!,badWord: function (text,words) { //# 敏感词过滤 text = String(text || ''); words = words || []; var reg = new RegExp(words.join('|'),'g'),_self = this; return text.replace(reg,function ($0) { var length = String($0 || '').length; return _self.repeat('*',length); }); }

};
