js嵌套数组重排序
大白莎 人气:0总共遇到两个问题：
1、JS中for循环输出同一变量值的问题
js事件处理器在线程空闲事件不会运行，导致最后运行的时候输出的都是i最后的值。
解决方法：在循环中声明 this.content1 = {}
2、排序算法在序号到10以后出错
解决方法：没注意string和int，原数据为string
原数据：
目标：将table、text、image合并到一个content里面，并按blockNO排序
代码：
<script>
export default {
data() {
return {
data: [],
content1: {}
}
},
created() {
this.test()
},
methods: {
async test() {
const { data: res } = await this.$http.get('test1')
for (let i = 0; i < res.length; i++) {
this.data1 = {}
this.data1.name = res[i].name
this.data1.blockNO = res[i].blockNO
this.data1.class = res[i].class
this.data1.id = res[i].id
this.data1.children = []
this.data1.content = []
if (res[i].text) {
for (let j = 0; j < res[i].text.length; j++) {
this.content1 = {}
this.content1.blockNO = res[i].text[j].blockNO
this.content1.type = 'text'
this.content1.detail = res[i].text[j].text
this.data1.content.push(this.content1)
}
}
if (res[i].table) {
for (let j = 0; j < res[i].table.length; j++) {
this.content1 = {}
this.content1.blockNO = res[i].table[j].blockNO
this.content1.type = 'table'
this.content1.detail = res[i].table[j].table
this.data1.content.push(this.content1)
}
}
if (res[i].image) {
for (let j = 0; j < res[i].image.length; j++) {
this.content1 = {}
this.content1.blockNO = res[i].image[j].blockNO
this.content1.type = 'image'
this.content1.detail = res[i].image[j].image
this.data1.content.push(this.content1)
}
}
for (let j = 1; j < this.data1.content.length; j++) {
for (let i = 0; i < this.data1.content.length - j; i++) {
if (
parseInt(this.data1.content[i].blockNO) >
parseInt(this.data1.content[i + 1].blockNO)
) {
let tempnum = this.data1.content[i + 1]
this.data1.content[i + 1] = this.data1.content[i]
this.data1.content[i] = tempnum
}
}
}
this.data.push(this.data1)
}
console.log(this.data)
}
}
}
