JavaScript+HTML實(shí)現(xiàn)學(xué)生信息管理系統(tǒng)

 更新時(shí)間：2021年04月19日 10:16:52   作者：Dev-Flow  
這篇文章主要介紹了JavaScript實(shí)現(xiàn)學(xué)生信息管理系統(tǒng),文中有非常詳細(xì)的代碼示例,對(duì)正在學(xué)習(xí)js的小伙伴們有一定的幫助,需要的朋友可以參考下

一、前言

用數(shù)組來(lái)存儲(chǔ)所有學(xué)生對(duì)象的信息，實(shí)現(xiàn)了雙向更新，初始時(shí)（數(shù)組內(nèi)的對(duì)象信息“填充界面”），后面的界面操作可以更新數(shù)組內(nèi)對(duì)象的信息（數(shù)量和本身數(shù)據(jù)域信息）。

優(yōu)點(diǎn)：JQuery代碼處理的許多細(xì)節(jié)較好。

使用HTML5的pattern+正則表達(dá)式，實(shí)現(xiàn)表單驗(yàn)證以及相應(yīng)提示。

缺點(diǎn)：后臺(tái)刪除學(xué)生對(duì)象的信息代碼處理效率較低（“假”刪除：移動(dòng)學(xué)生對(duì)象索引的位置+變換數(shù)組長(zhǎng)度）。

CSS部分——界面的縮放存在問(wèn)題。（沒(méi)打算走前端/暫時(shí)懶得修改）。.

部分代碼可以更好的處理已達(dá)到復(fù)用的目的，未處理。

二、效果圖

三、代碼

沒(méi)有刪去寫(xiě)代碼過(guò)程中做改進(jìn)之前的代碼，看上去代碼有點(diǎn)長(zhǎng)（保留了寫(xiě)代碼的思考過(guò)程）

刪去注釋了的代碼以及一些不必要的內(nèi)容，代碼也不是太長(zhǎng)。

四、學(xué)生信息管理系統(tǒng)主界面

   （1）系統(tǒng)主界面如圖2所示，要求學(xué)生的信息存入一個(gè)數(shù)組中，每個(gè)學(xué)生是一個(gè)對(duì)象。

圖1 學(xué)生信息管理系統(tǒng)主界面

（2）點(diǎn)擊“新增”按鈕顯示一個(gè)新的窗體，錄入學(xué)生的基本信息，在保存時(shí)，需要檢驗(yàn)數(shù)據(jù)是否合法。新增頁(yè)面如圖3所示。

圖2 新增界面

（3）點(diǎn)擊“修改”按鈕顯示一個(gè)新的窗體，修改當(dāng)前行的學(xué)生信息。

圖3 修改界面

（4）點(diǎn)擊“查看”按鈕顯示一個(gè)新的窗體，顯示當(dāng)前行的學(xué)生信息。此時(shí)輸入框的內(nèi)容不可修改。

圖4 查看

（5）其他要求

  • 點(diǎn)擊“刪除”按鈕，顯示一個(gè)詢(xún)問(wèn)提示，如果選擇是就刪除當(dāng)前行?？梢远噙x刪除，點(diǎn)擊全選時(shí)是選擇當(dāng)前頁(yè)所有學(xué)生。
  • 隔行換色。
  • 行的移入移出效果（hover）。
  • 能夠?qū)崿F(xiàn)下一頁(yè)和上一頁(yè)的功能,不能翻頁(yè)的時(shí)候給出提示。
  • 展示出共有多少條數(shù)據(jù)，每頁(yè)的數(shù)據(jù)條數(shù)，當(dāng)前頁(yè)數(shù)。
