Vue Spa 页面的登录

Vue spa 微信公众号的
分享
Main.js
import wx from 'weixin-js-sdk';
router.afterEach((to, from) => {
let _url =window.location.origin+"/shop"+ to.fullPath;
//非ios设备,切换路由时候进行重新签名
if(window.__wxjs_is_wkwebview !== true) {
axios.post('/wechat_config',qs.stringify({uri:_url})).then(function (res) {
//注入配置
wx.config({
debug:false,
appId:res.data.data.item.appId,

jsApiList:["updateAppMessageShareData",'updateTimelineShareData','getLocation',"onMenuShareAppMessage","onMenuShareTimeline","onMenuShareWeibo"]
})
})
}
// ios设备进入页面则进行js-sdk签名
if(window.__wxjs_is_wkwebview === true) {
axios.post(' /wechat_config',qs.stringify({uri:_url})).then(function(res) {
wx.config({

jsApiList:['updateAppMessageShareData','updateTimelineShareData','getLocation',"onMenuShareAppMessage","onMenuShareTimeline","onMenuShareWeibo"]
})
})
}
let totitle ="";
let todesc ="";
// to.meta. share 是自定义路由的分享信息
//还可以在router meta自定义更多参数
if(typeof(to.meta.share) === "undefined"){
totitle ="我是没有分享自定义的标题";
todesc ="我是没有分享的分享详情";
}else{
totitle =to.meta. share.title;
todesc =to.meta. share.desc;
}
let share = {
title:totitle, //分享标题
desc:todesc, //分享描述
link:_url, //分享链接,该链接域名或路径必须与当前页面对应的公众号JS安全域名一致
imgUrl: '',//分享图标正式
success:function () {
//设置成功
}
}
//微信分享配置
wx.ready(function () {
wx.updateAppMessageShareData(share);
wx.updateTimelineShareData(share);
wx.onMenuShareAppMessage(share);
wx.onMenuShareTimeline(share);
wx.onMenuShareWeibo(share);
})
})
值得注意的是微信1.4版本分享给朋友的最新接口就算在客户端6.7.2版本也是会出现没有图片的问题所以还是将老的版本也写进去兼容一下
Vue 转换时间戳
Util.js
export function formatDate (date, fmt) {
if(/(y+)/.test(fmt)) {
fmt =fmt.replace(RegExp.$1, (date.getFullYear() + '').substr(4 - RegExp.$1.length));
}
let o = {
'M+':date.getMonth() + 1,
'd+':date.getDate(),
'h+':date.getHours(),
'm+':date.getMinutes(),
's+':date.getSeconds()
};
for (let kin o) {
if (newRegExp(`(${k})`).test(fmt)) {
letstr = o[k] + '';
fmt= fmt.replace(RegExp.$1, (RegExp.$1.length === 1) ? str : padLeftZero(str));
}
}
return fmt;
};
function padLeftZero (str) {
return ('00'+ str).substr(str.length);
};
需要转换的页面引用
import {formatDate} from '@/util.js';
filters: {
formatDate(time) {
vardate = new Date(time);
return formatDate(date, 'yyyy-MM-dd hh:mm');
}
}
使用:
{{ _time*1000 | formatDate}}
vue防止用户疯狂点击和加载
Util.js
/**
*函数防抖 (只执行最后一次点击)
* @param fn
* @param delay
* @returns{Function}
* @constructor
*/
export const Debounce = (fn, t) => {
let delay =t || 500;
let timer;
returnfunction () {
let args= arguments;
if(timer){
clearTimeout(timer);
}
timer =setTimeout(() => {
timer = null;
fn.apply(this, args);
},delay);
}
};
/**
*函数节流
* @param fn
* @paraminterval
* @returns{Function}
* @constructor
*/
export const Throttle = (fn, t) => {
let last;
let timer;
let interval= t || 500;
returnfunction () {
let args= arguments;
let now= +new Date();
if (last&& now - last < interval) {
clearTimeout(timer);
timer = setTimeout(() => {
last = now;
fn.apply(this, args);
},interval);
} else {
last= now;
fn.apply(this, args);
}
}
};
vue 朋友圈的天数计算
util.js
caculate_time(created_at){
letnow_time = new Date().getTime();
letold_time = parseInt(created_at) * 1000;
lettime = now_time - old_time;
let day = parseInt(time / (24 * 60 * 60));//计算整数天数
//计算出相差天数
day=Math.floor(time/(24*3600*1000))
//计算出小时数
letleave1=time%(24*3600*1000) //计算天数后剩余的毫秒数
lethours=Math.floor(leave1/(3600*1000))
//计算相差分钟数
letleave2=leave1%(3600*1000) //计算小时数后剩余的毫秒数
letminutes=Math.floor(leave2/(60*1000))
//计算相差秒数
letleave3=leave2%(60*1000) //计算分钟数后剩余的毫秒数
letseconds=Math.round(leave3/1000)
return[day,hours,minutes,seconds];
}
使用:
let ts_time = that.caculate_time(val.created_at);
let msg = '';
if(ts_time[0] != 0){
msg =ts_time[0]+'天前';
}else if(ts_time[1]!= 0){
msg =ts_time[1]+'小时前';
}else if(ts_time[2]!= 0){
msg =ts_time[2]+'分钟前';
}else if(ts_time[3]!= 0){
msg = '刚刚';
}
