JavaScript常用方法（工具类的封装）
日期格式化
Date.prototype.format = function (fmt) { //author: meizz
var o = {
"M+": this.getMonth() + 1, //月份
"d+": this.getDate(), //日
"h+": this.getHours(), //小时
"m+": this.getMinutes(), //分
"s+": this.getSeconds(), //秒
"q+": Math.floor((this.getMonth() + 3) / 3), //季度
"S": this.getMilliseconds() //毫秒
};
if (/(y+)/.test(fmt))
fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
for (var k in o)
if (new RegExp("(" + k + ")").test(fmt))
fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
return fmt;
};
new Date().format("yyyy-MM-dd hh:mm")
距离格式化
convertDistanceStr =function(distance) {
if (!distance) { return ""; } else if (distance < 1000) { return distance + "m" } else if (distance >= 1000 && distance < 100000) { return (distance / 1000.0).toFixed(1) + "km" } else if (distance > 100000) { return (distance / 1000.0).toFixed(0) + "km" } else { return ""; }};
格式验证
checkStr (str, type) { switch (type) { case 'phone': //手机号码 return /^1[3|4|5|7|8][0-9]{9}$/.test(str); case 'tel': //座机 return /^(0\d{2,3}-\d{7,8})(-\d{1,4})?$/.test(str); case 'card': //身份证 return /^\d{15}|\d{18}$/.test(str); case 'pwd': //密码以字母开头，长度在6~18之间，只能包含字母、数字和下划线 return /^[a-zA-Z]\w{5,17}$/.test(str) case 'postal': //邮政编码 return /[1-9]\d{5}(?!\d)/.test(str); case 'QQ': //QQ号 return /^[1-9][0-9]{4,9}$/.test(str); case 'email': //邮箱 return /^[\w-]+(\.[\w-]+)*@[\w-]+(\.[\w-]+)+$/.test(str); case 'money': //金额(小数点2位) return /^\d*(?:\.\d{0,2})?$/.test(str); case 'URL': //网址 return /(http|ftp|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&:/~\+#]*[\w\-\@?^=%&/~\+#])?/.test(str) case 'IP': //IP return /((?:(?:25[0-5]|2[0-4]\\d|[01]?\\d?\\d)\\.){3}(?:25[0-5]|2[0-4]\\d|[01]?\\d?\\d))/.test(str); case 'date': //日期时间 return /^(\d{4})\-(\d{2})\-(\d{2}) (\d{2})(?:\:\d{2}|:(\d{2}):(\d{2}))$/.test(str) || /^(\d{4})\-(\d{2})\-(\d{2})$/.test(str) case 'number': //数字 return /^[0-9]$/.test(str); case 'english': //英文 return /^[a-zA-Z]+$/.test(str); case 'chinese': //中文 return /^[\u4E00-\u9FA5]+$/.test(str); case 'lower': //小写 return /^[a-z]+$/.test(str); case 'upper': //大写 return /^[A-Z]+$/.test(str); case 'HTML': //HTML标记 return /<("[^"]*"|'[^']*'|[^'">])*>/.test(str); default: return true; } }
读取url参数
getUrlParam = function (name) {
var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
var r = window.location.search.substr(1).match(reg);
if (r != null) {
return decodeURIComponent(r[2]);
}
return "";
};
读取全部url参数
getUrlParams = function (url) { var params = {}; var search = url.search; if (search) { while (search.indexOf("?") == 0) { search = search.substr(1); } var arr = search.split("&"); for (var i = 0; i < arr.length; i++) { var kv = arr[i].split("="); if (kv.length >= 2) { params[kv[0]] = decodeURIComponent(kv[1]); } } } return params; };
初始化评分星星
<span class="score-stars" data-value=""></span><br>initScoreStars = function () { $(".score-stars").each(function (index, item) { var value = parseFloat($(item).attr("data-value")); var stars = ""; for (var i = 0; i < 5; i++) { if (value - i >= 0.9) { stars += "<i class='iconfont icon-star'></i>"; } else if (value - i >= 0.1) { stars += "<i class='iconfont icon-starhalf'></i>"; } else { stars += "<i class='iconfont icon-star muted'></i>"; } } $(item).html(stars); }); };
判断是否是pc端
isPC () {//是否为PC端
var userAgentInfo = navigator.userAgent; var Agents = ["Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod"]; var flag = true; for (var v = 0; v < Agents.length; v++) { if (userAgentInfo.indexOf(Agents[v]) > 0) { flag = false; break; } } return flag;}判断是否为微信端
isWXBrowser = function () {
return navigator.userAgent.toLowerCase().indexOf("micromessenger") >= 0;
}
微信支付签名时间戳，签名随机串
var timestamp = Math.round(new Date().getTime() / 1000).toString();//时间戳
var nonceStr = Math.round(Math.random() * 100000000).toString();随机串
http请求
app.getJSON = function (url, data, successFunc, errorFunc) {
app.request("get", url, data, successFunc, errorFunc);
}
app.delete = function (url, data, successFunc, errorFunc) {
app.request("delete", url, data, successFunc, errorFunc);
}
// 提交数据
app.post = function (url, data, successFunc, errorFunc) {
app.request("post", url, data, successFunc, errorFunc);
}
app.put = function (url, data, successFunc, errorFunc) {
app.request("put", url, data, successFunc, errorFunc);
}
app.request = function (method, url, data, successFunc, errorFunc) {
if (method.toLowerCase() == "post" || method.toLowerCase() == "put") {
if (data && typeof data != "string") {
data = JSON.stringify(data);
} else if (!data) {
data = "";
}
}
$.ajax({
type: method,
dataType: "json",
url: url,
data: data,
contentType: "application/json",
beforeSend: function (request) {
request.setRequestHeader("appKey", conf.appKey);
},
success: function (res) {
if (res.status == "9901") {
var baseUrl;
if(window.location.href.toString().indexOf("/new/")>0){
baseUrl=conf.newWebBaseUrl;
}
else if(window.location.href.toString().indexOf("/newStore/")>0){
baseUrl=conf.newStoreBaseUrl;
}
else {
baseUrl=conf.webBaseUrl;
}
} else if (typeof successFunc == "function") {
successFunc(res);
}
},
error: function () {
if (typeof errorFunc == "function") {
errorFunc();
}
}
});
}
用法
app.getJSON(conf.apiBaseUrl + "/users/updAutoRebateMerchant", {
merchantId:merchantId
}, function (res) {
if (res.status == "0000") {
//成功
} else if (res.message) {
mui.alert(res.message);
}
});
