我现在要实现的是v-for每次按2条项目这样来循环，里面有函数是处理index,可是会出现符合的index重复调用的情况。

template：

scrip：

let count = 3

let indexArr = []

export default {

name: 'reportPage',

data () {

return {

tdata: [1,2,3],

myForm: {

'myCompany': '海南凯迪网络资讯股份有限公司',

'myTips': ''

},

totalPage: 4,

}

},

mounted () {

let that = this

let height = document.body.clientHeight - 60

that.$refs.main.style.height = height+'px'

// alert(((that.tdata.length - 1)%2))

if (that.tdata.length === 1 ) {

that.totalPage = 4

}else {

that.totalPage = 4 + Math.floor((that.tdata.length - 1)/2) + 1

}

// alert(that.totalPage)

// if ((that.tdata.length%2) && tdata.length>1) {

// that.totalPage = 3 + that.tdata.length + 1

// }else{

// that.totalPage = 3 + that.tdata.length

// }

},

methods: {

submitForm (e) {

let that = this

e.preventDefault()

that.form.validateFields((err, values) => {

if (!err) {

console.log('Received values of form: ', values);

}

})

},

textChange () {

let that = this

// console.log('tips==',that.form.getFieldValue('tips'))

that.myForm.myTips = that.form.getFieldValue('tips')

},

getPageNum (index) {

console.log("index=", index)

// console.log("count1=",count)

// if (indexArr.indexOf(index) == -1) {

// indexArr.push(index)

// count--

// }

// console.log("count2==",count)

// console.log('sum=', index + count)

// return index + count

}

}

}

打印的结果：

有谁遇到同样的问题吗？我想要的结果是打印出来的index不是重复执行的，就是执行一次。
