Reactjs如何實(shí)現(xiàn)通用分頁(yè)組件

這篇文章給大家分享的是有關(guān)Reactjs如何實(shí)現(xiàn)通用分頁(yè)組件的內(nèi)容。小編覺得挺實(shí)用的，因此分享給大家做個(gè)參考，一起跟隨小編過(guò)來(lái)看看吧。

專注于為中小企業(yè)提供成都網(wǎng)站建設(shè)、成都做網(wǎng)站服務(wù),電腦端+手機(jī)端+微信端的三站合一,更高效的管理,為中小企業(yè)天水免費(fèi)做網(wǎng)站提供優(yōu)質(zhì)的服務(wù)。我們立足成都，凝聚了一批互聯(lián)網(wǎng)行業(yè)人才，有力地推動(dòng)了上千余家企業(yè)的穩(wěn)健成長(zhǎng)，幫助中小企業(yè)通過(guò)網(wǎng)站建設(shè)實(shí)現(xiàn)規(guī)模擴(kuò)充和轉(zhuǎn)變。

大家多少都自己寫過(guò)各種版本的分頁(yè)工具條吧，像純服務(wù)版的，純jsWeb板的，Angular版的，因?yàn)檫@個(gè)基礎(chǔ)得不能再基礎(chǔ)的功能太多地方都會(huì)用到，下面我給出以個(gè)用ReactJS實(shí)現(xiàn)的版本，首先上圖看下效果：

注意這個(gè)組件需要ES6環(huán)境，最好使用NodeJS結(jié)合Webpack來(lái)打包：webpack --display-error-details --config webpack.config.js

此React版分頁(yè)組件請(qǐng)親們結(jié)合redux來(lái)使用比較方便，UI = Fn(State)

基本流程就是：用戶交互->Action->Reduce->Store->UIRender

了解以上基礎(chǔ)知識(shí)卻非常必要，但不是我此次要說(shuō)的重點(diǎn)，以上相關(guān)知識(shí)請(qǐng)各位自行補(bǔ)腦，廢話就不多說(shuō)，直接上代碼。
