[Electron]vanilla js套件系列-Modal:modal-vanilla

前提情要

筆者工作環境中前端使用angular框架撰寫,model binding根本無敵阿,且typescript語言,對於筆者這種後端人員來說,上手速度是頗快的,扯遠了,筆者要強調的是能用angular或其他兩大框架寫前端根本就是一等公民,來到Electron專案,是有神者有做angular-electronvue-electron的版本,但筆者覺得自己前端實力不夠,怕handle不了,還是乖乖用純js撰寫其專案,根本就變回二等公民,這篇主要介紹其中需要modal功能時,挑選只有vanilla jsmodal套件來實作。

內容

引入modal.min.js

筆者這邊使用的是modal-vanilla,引用方式也滿簡單的,只要從該github連結中進到dist資料夾,下在modal.min.js到專案中引入即可

<script src="./scripts/modal.min.js"></script>

筆者這邊測試發現,需要引入bootstrap的css才會正常作業

宣告Modal區塊

接著使用官方的範例code吧,宣告一個modal區塊

實際效果

實際效果如下,畫面上有一顆按鈕,按下後會浮出modal視窗,完美

結論

筆者覺得gihub上的大神們都很強,該套件就是盡量寫成跟bootstrapmodal使用方式很類似,若你習慣使用bootstrap modal,這個應該很容易上手,筆者這邊只做了簡單的示範,還有事件可以攔截擴充,應該就以vanilla js的方式解決,已經非常足夠了。
