I want to create json format from variable javascript.
var code="1,description 1;2,description 2;3,description 3;4,description 4";
I want to change to JSON Format become:
var result = [{"key":"1", "value","description 1"},{"key":"2", "value","description 2"},{"key":"3", "value","description 3"},{"key":"4", "value","description 4"} ]
I already using split but too difficult because use 2 split(split by "," and ";"). How to fix it?
Thank you.
Regards, Bobby
Note, it should be:
{"key":"1", "value": "description 1"}
You need to use multiple loops. And the process is:
;.,.Snippet
// Define final object:
var finalArray = [];
var code = "1,description 1;2,description 2;3,description 3;4,description 4";
// Step one: Split on ;
code = code.split(";");
// Step two: Split on ,
for (var i = 0; i < code.length; i++) {
code[i] = code[i].split(",");
finalArray.push({
"key": code[i][0],
"value": code[i][1]
});
}
// Let's see the output:
console.log(finalArray);
When parsing stuff in Javascript you usually make a regex that represents one data item and globally replace it with a function that populates some structure and pushes it into a collection:
let data = [];
let str = "1,description 1;2,description 2;3,description 3;4,description 4";
str.replace(/(.+?),(.+?)(;|$)/g, (_, key, value) => data.push({key, value}));
console.log(data)The reason of (ab)using .replace for this is that global .match doesn't support groups.
str.replace(/(.+?),(.+?)(;|$)/g, (_, key, value) => data.push({key, value}));You could map the splitted parts with a new object for the key and value properties.
var code="1,description 1;2,description 2;3,description 3;4,description 4",
result = code.split(';').map(function (a) {
var p = a.split(',');
return { key: p[0], value: p[1] };
});
console.log(result);
{"key":"1", "value","description 1"}not valid
