最近又作了個投票的H5活動頁面,此次跟以前的有點不太同樣。根據需求要用戶關注了微信公衆號以後才能進行投票。這樣就不是簡單的數據邏輯與數據交互了,須要跟微信服務器通信拿到用戶信息。javascript
之前的這類活動是一種比較弱的先後端分離,前端寫頁面、效果、處理數據交互以及邏輯。這些東西放在靜態服務器上。後端處理數據存儲等。這樣就實現了一種簡單的先後分離,作起來效率相對也教快一些。css
此次其實其餘的也沒有什麼變化,而後就是在投票頁面須要交給後端去跳轉微信服務器拿到用戶信息。對於這樣的場景個人想法是有兩種方式:html
1. 讓後端來渲染這個頁面,用後端模板來作。這樣在開發和調試方面耦合性就比較高。 2. 前端用vue寫好全部的邏輯,頁面打包到一個js中實現。這樣耦合性就不是那麼高了,各自專一本身的模塊,效率也會提高許多。
固然鑑於時間要求以及後端原本就擁有的一套基礎設施,選擇了第二種方案。不管在效率和工做量上都有必定的減輕。雖然本身以爲這麼作徹底是一種大材小用,可是知足需求才是王道。說幹就幹唄!

這裏有幾點說明就是1.依然使用了jQuery,由於時間以及原來有這樣的邏輯代碼。最主要的是懶吧2.判斷是否在微信中進入這個頁面,是後臺返回一個值我去讀取而後操做vue
//判斷是否爲微信 if($('.weichat').attr('tip') != '') { $('body').css('background-color', '#fff'); $('body').html('<p style="text-align:center;">'+$('.weichat').attr('tip')+'</p>'); return false; }
而後這裏有一個坑,由於出於移動端的網絡考慮。因此把存儲的問題放在前端存儲,讓用戶有個交互的感。在對null處理是,iOS和Android上的值還不同,iOS上是字符串,這個坑也是調了很久才發現。java
//iOS上 oldTime = !!(navigator.userAgent).match(/\(i[^;]+;( U;)? CPU.+Mac OS X/) && (oldTime == 'null') ? null : oldTime;
結果以下圖
jquery
最終出來的結果雖然知足了需求,可是本身仍是以爲槽點不少。歡迎各位來噴O(∩_∩)O哈哈~ajax
