14.使用nodejs将规定格式的txt转化为json数据

这是txt文件内容

注:安装nodejs

bulid.js

// 加载File System读写模块  
var fs = require('fs');

var os = require('os');
//读取文件
var o = fs.readFileSync('./test.txt','utf-8')


//分解txt文件
let arr = o.split('
')
let newArr = arr.filter(function(value,index,arr){
    if(value!=''){
        return true
    }
    return false
})
//循环分解数组中的元素
let len = newArr.length

let ts = []//诗分组

tsToArr()
writeTsToJson()
function tsToArr(){
    let $ts = []
    for(let i=0;i<len;i++){
        
        let str1 = newArr[i].slice(0,3)
        
        let str2 = ''
        //判断下一个是否为标题
        if(i+1<len){
            str2 = newArr[i+1].slice(0,3)
        }
        
        $ts.push(newArr[i])
        if(!isNaN(parseInt(str2))){
            ts.push($ts)
            $ts = []
        }
    }
}

function writeTsToJson(){
    let $len = ts.length
    let allTs = []

    for(let i=0;i<$len;i++){
        var tsObj = {}
        
        oneTsLen = ts[i].length
        let content = []
        for(let k=0;k<oneTsLen;k++){
            if(k==0){
                let IDNAMETITLE =  ts[i][0].split('：')
                let str0len = IDNAMETITLE[0].length
                //id
                //title
                let idAndName = IDNAMETITLE[0].split('')
                let id = ''
                for(let j =0;j<idAndName.length;j++){
                    if(j>2){
                        break
                    }
                    id+=idAndName[j]
                }
                let name = ''
                for(let m =0;m<idAndName.length;m++){
                    if(m<=2){
                        continue
                    }
                    name+=idAndName[m]
                }
            
                let title = IDNAMETITLE[1]
                tsObj.id = id
                tsObj.author = name
                tsObj.title = title
            }else{
                content.push(ts[i][k])
            }
        }
        //content
        tsObj.content = content
        allTs.push(tsObj)
    }
    var filename = "./test1.json";
    fs.writeFileSync(filename, JSON.stringify(allTs));
}

在当前项目路径下使用cmd或者终端

node build.js

搞定
