Add a property to a JavaScript object using a variable as the name?
You can use this equivalent syntax:
obj[name] = valueExample:
let obj = {};obj["the_key"] = "the_value";or with ES6 features:
let key = "the_key";let obj = { [key]: "the_value",};in both examples, console.log(obj) will return: { the_key: 'the_value' }
With ECMAScript 2015 you can do it directly in object declaration using bracket notation:
var obj = { [key]: value}Where key can be any sort of expression (e.g. a variable) returning a value:
var obj = { ['hello']: 'World', [x + 2]: 42, [someObject.getId()]: someVar}
You can even make List of objects like this
var feeTypeList = [];$('#feeTypeTable > tbody > tr').each(function (i, el) { var feeType = {}; var $ID = $(this).find("input[id^=txtFeeType]").attr('id'); feeType["feeTypeID"] = $('#ddlTerm').val(); feeType["feeTypeName"] = $('#ddlProgram').val(); feeType["feeTypeDescription"] = $('#ddlBatch').val(); feeTypeList.push(feeType);});
