window.onload = function() {
    $.ajax({
        url : "/auctionCount.kh",
        data:{memberNo:memberNo},
        success : function(list){
            for(let i=0;i<list.length;i  ){
                console.log(list[i]);
            }
        }
    });
};

I got it as a hashmap type in sql.

I need to extract divno, prevcount, projectname, projectno, viewdif, viewcount separately here but I don't know how

CodePudding user response：

if you like one liner you can do it like this

let data = [{DIVNO: 4, PREVCOUNT: 5, PROJECTNAME: 'xx', PROJECTNO: 21, VIEWCOUNT: 0, VIEWDIF: 0}, {DIVNO: 5, PREVCOUNT: 6, PROJECTNAME: 'xx2', PROJECTNO: 22, VIEWCOUNT: 1, VIEWDIF: 1}];


const result = data.reduce((res, item) => Object.fromEntries(
  Object.entries(item).map(([k, v]) => [k, [...(res[k] || []), v]])
), {})

console.log(result);

CodePudding user response：

You can do something like:

let data = [{DIVNO: 4, PREVCOUNT: 5, PROJECTNAME: 'xx', PROJECTNO: 21, VIEWCOUNT: 0, VIEWDIF: 0}, {DIVNO: 5, PREVCOUNT: 6, PROJECTNAME: 'xx2', PROJECTNO: 22, VIEWCOUNT: 1, VIEWDIF: 1}];
let result = {DIVNO: [], PREVCOUNT: [], PROJECTNAME: [], PROJECTNO: [], VIEWCOUNT: [], VIEWDIF: []};
data.map(r=> {
        result.DIVNO.push(r.DIVNO);
    result.PREVCOUNT.push(r.PREVCOUNT);    
    result.PROJECTNAME.push(r.PROJECTNAME);
    result.PROJECTNO.push(r.PROJECTNO);
    result.VIEWCOUNT.push(r.VIEWCOUNT);
    result.VIEWDIF.push(r.VIEWDIF);
})
console.info(result);
console.info(result.DIVNO);
console.info(...result.DIVNO);

If some values doesn't come in your ajax response, you would need to validate based in certain condition, but its based on your needs.

CodePudding user response：

If you simply wish to access them, you'd just use the dot operator:

console.log(list[i].DIVNO);
console.log(list[i].VIEWDIF);
// etc..

If you want to access the objects key-value pairs, regardless of what they are:

for (const [key, value] of Object.entries(list[i])) {
    console.log(`${key}: ${value}`);
}
