8 meta tag MUST for SEO
title
<title>創世押業系統:產品簡介</title>
description
<meta name="description" content="InnoNext (HK) Company 創世(香港)公司. +852 3502 4350. info@innopawn.com. 香港荃灣沙咀道40-50號榮豐工業大廈17樓11B室" />
canonical
很多網站都會有多於一個網址,例如:
innopawn.com
www.innopawn.com
從Google 的搜尋引擎的角度,會導致內容重複的問題,而引至被搜尋引擎懲罰。所以,可以用 canonical 解決這個問題
<link rel="canonical" href="https://www.innopawn.com" />
charset
<meta charset="UTF-8">
robot
..
hreflang
如果網站內包含多種語言,就需要用 hreflang 來提示搜尋引擎展示正確的網頁給不同地區的訪客
<link rel="alternate" href="http://www.innopawn.com" hreflang="zh-hk" />
og
og (Open Graph)並非用於 SEO 中,但對網頁於 Facebook、LINE 等社交媒體正確地呈現有莫大幫助,其中 og:title、og:description、og:image 至為重要,分別決定了網頁於社交媒體分享時顯示的標體、形容和縮圖。
keywords
在2009年開始,就已經失效

Fixed jscolor.js not work with Vue updated by AJAX color value
For example:
We got some data form AJAX and the valuable is “topBGColor”.
in HTML
<input data-jscolor=""> add ref="topBGColor" <input data-jscolor="" ref="topBGColor">
in Javascript (After get ajax value)
let topBGColor = "#ff0000"; this.$refs.topBGColor.style = 'background-image: linear-gradient(to right, '+topBGColor+' 0%, '+topBGColor+' 30px, rgba(0, 0, 0, 0) 31px, rgba(0, 0, 0, 0) 100%) !important; background-position: left top, left top !important; background-size: auto, 32px 16px !important; background-repeat: repeat-y, repeat-y !important; background-origin: padding-box, padding-box !important; padding-left: 40px !important;';
