树形数据转json
数据格式
返回数据格式1： （最后一级children如果为空，则为children:[]）
transData(data) {
const resData = data
const tree = []
for (let i = 0; i < resData.length; i++) {
if (resData[i]['domainLevel'] === '1') {
const obj = {
domainCode: resData[i]['domainCode'],
domainDescription: resData[i]['domainDescription'],
domainLevel: resData[i]['domainLevel'],
children:[]
}
tree.push(obj)
resData.splice(i, 1)
i--
}
}
this.run(tree, resData)
return tree
},
run(chiArr, resData) {
if (resData && resData.length !== 0) {
for (let i = 0; i < chiArr.length; i++) {
for (let j = 0; j < resData.length; j++) {
if (resData[j]['domainCode'].substring(0, chiArr[i].domainCode.length) === chiArr[i].domainCode && resData[j]['domainLevel'] === (parseInt(chiArr[i].domainLevel) + 1).toString()) {
const obj = {
domainCode: resData[j]['domainCode'],
domainDescription: resData[j]['domainDescription'],
domainLevel: resData[j]['domainLevel'],
children: []
}
chiArr[i].children.push(obj)
resData.splice(j, 1)
j--
}
}
this.run(chiArr[i].children, resData)
}
}
}
返回格式2：（最后一级children如果为空，则不要children）
transData(data) {
const resData = data
const tree = []
for (let i = 0; i < resData.length; i++) {
if (resData[i]['domainLevel'] === '1') {
const obj = {
domainCode: resData[i]['domainCode'],
domainDescription: resData[i]['domainDescription'],
domainLevel: resData[i]['domainLevel']
}
tree.push(obj)
resData.splice(i, 1)
i--
}
}
this.run(tree, resData)
return tree
},
run(chiArr, resData) {
for (let i = 0; i < chiArr.length; i++) {
const temp = resData.filter(item => item.domainCode.substring(0, chiArr[i].domainCode.length) === chiArr[i].domainCode && item.domainLevel === (parseInt(chiArr[i].domainLevel) + 1).toString())
if (temp && temp.length > 0) {
chiArr[i].children = temp
}
if (chiArr[i].children) {
this.run(chiArr[i].children, resData)
}
}
},
