实现的是用vue项目实现原生的table求一列的数值总和,其中数值是后期通过input输入的

html代码

没放样式代码了, 这里只实现功能

js代码

var Main = {

data() {

return {

tableData6: [{

id: '12987122',

name: '王小虎111',

amount1: '234',

amount2: '3.2',

amount3: 10,

amount4: ''

}, {

id: '12987123',

name: '王小虎222',

amount1: '165',

amount2: '4.43',

amount3: 12,

amount4: ''

}, {

id: '12987124',

name: '王小虎333',

amount1: '324',

amount2: '1.9',

amount3: 9,

amount4: ''

}, {

id: '12987125',

name: '王小虎444',

amount1: '621',

amount2: '2.2',

amount3: 17,

amount4: ''

}, {

id: '12987126',

name: '王小虎555',

amount1: '539',

amount2: '4.1',

amount3: 15,

amount4: ''

}],

};

},

computed: {

sumAmount() {

return this.tableData6.map(row => row.amount1).reduce((acc, cur) => (parseInt(cur) + acc), 0)

},

sumMoney() {

return this.tableData6.map(row => row.amount2).reduce((acc, cur) => (parseFloat(cur) + acc), 0)

},

// 方法一:计算属性

sunCount() {

console.log('this.tableData6.map(row => row.amount4)', this.tableData6.map(row => row.amount4))

var bb = [];

for(var i in this.tableData6.map(row => row.amount4)){

if(this.tableData6.map(row => row.amount4)[i]) {

bb.push(this.tableData6.map(row => row.amount4)[i])

}

}

return bb.reduce((acc, cur) => (parseFloat(cur) + acc), 0)

// return this.tableData6.map(row => row.amount4).reduce((acc, cur) => (parseFloat(cur) + acc), 0)

// let num = 0

// for( let i = 0 ; i < this.tableData6.length ; i++) {

// num += Number(this.tableData6[i].amount4)

// }

// return num

}

},

methods: {

// 方法二: 通过change事件实现

// blurInput(index) {

// console.log('index', this.tableData6)

// let num = 0;

// this.tableData6[index].amount4 = number

// for( let i = 0 ; i < this.tableData6.length ; i++) {

// num += Number(this.tableData6[i].amount4)

// }

// this.englishAllNum = num

// },

}

};

var Ctor = Vue.extend(Main)

new Ctor().$mount('#app')
