js对象操作

Question

怎么将下面的对象：

varobj={'key1':'k1','value1':'v1','key2':'k2','value2':'v2'}

转换成

arr=[{'key':'k1','value':'v1'},{'key':'k2','value':'v2'}]

Answer 1

这种自己只能自己去判断呗

var arr = []
Object.keys(obj).forEach(d => d.startsWith('key') ? arr.push({key: obj[d], value: obj[d.replace('key', 'value')]}) : '' )

Answer 2

var obj={'key1':'k1','value1':'v1','key2':'k2','value2':'v2'}
var newStr="[";

for(var i in obj){
    newStr+="{"+"'"+i+"'"+":"+"'"+obj[i]+"'"+"},"
}


newStr=newStr.substring(0,newStr.length-1)
newStr+="]";

var Str = newStr.replace(/'/g,"\"");
console.log(Str);//"[{"key1":"k1"},{"value1":"v1"},{"key2":"k2"},{"value2":"v2"}]"
var newObj=JSON.parse(Str);
console.log(newObj) //[{key1:"k1"},{value1:"v1"},{key2:"k2"},{value2:"v2"}]

//明天继续看能不能写完
