vue中用js如何實(shí)現(xiàn)循環(huán)可編輯表格
vue用js實(shí)現(xiàn)循環(huán)可編輯表格
最近項(xiàng)目中需要實(shí)現(xiàn)一個(gè)很復(fù)雜的表格,嘗試用組件寫(xiě),半天寫(xiě)不出來(lái),循環(huán)真的好繞,最后直接求助大哥幫我用原生js寫(xiě)了一個(gè)。
大哥巴拉巴拉講了半天,先這樣在那樣,問(wèn)我懂了嗎
我說(shuō)懂了!
大哥說(shuō)那你寫(xiě)吧我看著。
我打開(kāi)vs table 停住。
大哥說(shuō) 算了我來(lái)吧 你看著。
躺著真好家人們 我是廢物。
表格的需求
簡(jiǎn)單總結(jié)一下就是
1.表格需要?jiǎng)討B(tài),根據(jù)輸入的數(shù)字顯示列數(shù)
2.表格可編輯、可禁用、可計(jì)算
其實(shí)單純表格可編輯是比較簡(jiǎn)單的,主要是根據(jù)輸入的年份顯示對(duì)應(yīng)的內(nèi)容,就需要對(duì)表格進(jìn)行循環(huán),我用組件循環(huán)的時(shí)候總是出現(xiàn)整行或者整列數(shù)據(jù)都一起變的情況,所以需要找到可以編輯單元格的方法。
經(jīng)過(guò)測(cè)試發(fā)現(xiàn)這個(gè)表格,原來(lái)的大哥也是用js寫(xiě)的,并且寫(xiě)死了30年,你輸入之后的年份,也只會(huì)出現(xiàn)30年的數(shù)據(jù)。所以我們直接跟他一樣!
我們可以定義一個(gè)對(duì)象,之后不斷地把內(nèi)容添加進(jìn)這個(gè)對(duì)象就可以。
首先在data中定義一個(gè)對(duì)象,即初始化的表格對(duì)象。
前兩列的表格我們可以直接寫(xiě)死,從合計(jì)開(kāi)始需要進(jìn)行循環(huán),所以我們直接從合計(jì)開(kāi)始,合計(jì)下再分收入和支出,收入和支出的元素直接根據(jù)公式來(lái)(改成小寫(xiě)是因?yàn)楹蠖私邮諗?shù)據(jù)不區(qū)分大小寫(xiě),發(fā)大寫(xiě)沒(méi)用)
還定義了當(dāng)前年份count,屬性名數(shù)組keys,和計(jì)算的幾個(gè)公式。
data () { return { // 初始化的表格對(duì)象 tableData: { "合計(jì)": { 'income': { 'a': 0.00, 'h': 0.00, 'i': 0.00, 'j': 0.00, 'k': 0.00, 'l': 0.00, 'm': 0.00, 'b': '--', 'n': '--', 'o': '--', 'p': '--', 'q': '--', 'c': 0.00, 'r': 0.00, 's': 0.00, 't': 0.00, 'd': '--', 'u': '--', 'v': '--', 'w': '--', 'x': '--', 'e': '--', 'f': '--' }, 'expend': { 'a': '--', 'h': '--', 'i': '--', 'j': '--', 'k': '--', 'l': '--', 'm': '--', 'b': 0.00, 'n': 0.00, 'o': 0.00, 'p': 0.00, 'q': 0.00, 'c': '--', 'r': '--', 's': '--', 't': '--', 'd': 0.00, 'u': 0.00, 'v': 0.00, 'w': 0.00, 'x': 0.00, 'e': 0.00, 'f': 0.00 } }, }, // 表格對(duì)象屬性名數(shù)組keys keys: [], // 填寫(xiě)的年份 默認(rèn)顯示五年 showYear: 5, // 當(dāng)前年度 count: new Date().getFullYear(), // 收入keys a的計(jì)算 incomeKeys: ['h', 'i', 'k', 'l', 'm'], // 支出keys b的計(jì)算 expendKeys: ['n', 'o', 'p', 'q'], // 收入keys c的計(jì)算 incomeKeys2: ['r', 's', 't'], // 支出keys d的計(jì)算 expendKeys2: ['u', 'v', 'w', 'x'] } }
然后在created中把年份加進(jìn)去
created() { // 在created元素周期就要生成表格 let tempAttr = null // 往tabledata里循環(huán)添加30年的數(shù)據(jù) for (let i = 0; i < 30; i++) { tempAttr = this.count + i + '' this.tableData[tempAttr] = { 'income': { 'a': 0.00, 'h': 0.00, 'i': 0.00, 'j': 0.00, 'k': 0.00, 'l': 0.00, 'm': 0.00, 'b': '--', 'n': '--', 'o': '--', 'p': '--', 'q': '--', 'c': 0.00, 'r': 0.00, 's': 0.00, 't': 0.00, 'd': '--', 'u': '--', 'v': '--', 'w': '--', 'x': '--', 'e': '--', 'f': '--' }, 'expend': { 'a': '--', 'h': '--', 'i': '--', 'j': '--', 'k': '--', 'l': '--', 'm': '--', 'b': 0.00, 'n': 0.00, 'o': 0.00, 'p': 0.00, 'q': 0.00, 'c': '--', 'r': '--', 's': '--', 't': '--', 'd': 0.00, 'u': 0.00, 'v': 0.00, 'w': 0.00, 'x': 0.00, 'e': 0.00, 'f': 0.00 }, // 把年份傳給后端 object.values只會(huì)獲取屬性值,所以多加一個(gè)year屬性 'year' : tempAttr } } // Object.keys獲取對(duì)象的屬性名賦值給keys this.keys = Object.keys(this.tableData) },
到這里我們表格就循環(huán)好了,接下來(lái)畫(huà)表格

可編輯的表格就實(shí)現(xiàn)了,我們還需要控制表格只能輸入數(shù)字,這個(gè)功能大哥當(dāng)然是讓我自己做,但我項(xiàng)目要的太急還沒(méi)來(lái)得及做,之后有時(shí)間實(shí)現(xiàn)一下校驗(yàn)的功能。
接下來(lái)是要根據(jù)輸入的項(xiàng)目年限(圖片上寫(xiě)錯(cuò)了)顯示對(duì)應(yīng)的列數(shù)。其實(shí)說(shuō)是項(xiàng)目年限,其實(shí)項(xiàng)目年限是不能填的,項(xiàng)目年限是建設(shè)年限和預(yù)算年限的合計(jì)。
所以很簡(jiǎn)單,我們監(jiān)聽(tīng)一下建設(shè)年限和預(yù)算年限,做個(gè)加法就行。但是問(wèn)題又來(lái)了,項(xiàng)目是用jeecg寫(xiě)的,v-decorator好像不支持監(jiān)聽(tīng),我寫(xiě)了沒(méi)反應(yīng),也可能是我不會(huì)。那就直接寫(xiě)change事件。
得到項(xiàng)目期限之后,需要表格跟著變化,其實(shí)就把項(xiàng)目期限的值賦給showYear就行。但是可能是因?yàn)橛辛薱hange事件,項(xiàng)目期限不能再寫(xiě)了,所以最后就直接寫(xiě)在建設(shè)和預(yù)算的change事件里了。
還有一個(gè)注意點(diǎn)是需要使用數(shù)字輸入框,這樣value才是一個(gè)值,直接input,每變化一次,內(nèi)容都會(huì)變化。輸入10會(huì)被當(dāng)成1和0。

// 建設(shè)年限變化 changeJsNum (value) { // 將值賦給建設(shè)年限 if(value === '' || value === null) { this.constructionPeriod = 0 } else{ this.constructionPeriod = value } // 根據(jù)預(yù)算年限進(jìn)行項(xiàng)目年限的計(jì)算 parseInt:字符串轉(zhuǎn)數(shù)字 if(this.operatingPeriod === ''){ this.projectPeriod = parseInt(this.constructionPeriod) } else { this.projectPeriod = parseInt(this.constructionPeriod) + parseInt(this.operatingPeriod) } // 計(jì)算之后 建設(shè)或預(yù)算年限的value置空(導(dǎo)致項(xiàng)目年限為空)時(shí),項(xiàng)目年限會(huì)為字符串0,所以if判斷要加上這個(gè) if(this.projectPeriod && this.projectPeriod!='0'){ this.showYear = this.projectPeriod } else { this.showYear = 5 } }, changeYyNum (value) { if(value === ''|| value === null) { this.operatingPeriod = 0 } else{ this.operatingPeriod = value } if(this.constructionPeriod === ''){ this.projectPeriod = parseInt(this.operatingPeriod) } else { this.projectPeriod = parseInt(this.operatingPeriod) + parseInt(this.constructionPeriod) } if(this.projectPeriod && this.projectPeriod!='0'){ this.showYear = this.projectPeriod } else { this.showYear = 5 } },
最后給大家看看我的表格!
項(xiàng)目
年限變化,列數(shù)變化。
