Javascript How Do Get Only First Value From Json Object Stack Overflow There can be multiple practices to access json object and array in javascript by the json.parse () method. either it can be accessed with a dot (.) operation or by a bracket pair ( []). Use [0] to access the first element, but in your case the s20 messages contains a string, not an array, so s20 messages[0] will just get you the first character ' ['. the solution would be to use json.parse() on the string first. practical example:. To get the first property of a json object with javascript, we can use the object.keys method. for instance, we write: "category1": ["image url 1 ", "image url 2 "], "category2": ["image url 3 ", "image url 4 "] to define the json json string. then we parse it into an object with json.parse. You could combine array#map with object.values() to achieve this; the mapping would transform each item of your input array x to the resulting array y. for each item in the resulting array y, you would select the first value of the corresponding item from x.

We can see that "name" is a property of an object that is inside the first element of an array named "data", which is itself inside the main object. so for example, if this object were being reference by a variable named "test", you could access the name as:. To get a single element of a json object, you can access it using dot notation or bracket notation in javascript. here's an example using bracket notation: const name = myobj["name"]; console. log (name); output: "shecodes". Try 'element.price' instead of 'element.price [0]', that splits the price in an array, which is what your code does, you get the first character of the price which is '1'. You may be able to get the first that is defined in the original json string if you use json.parse() and pass it a "reviver" function. i think it'll give you the properties you encounter in order, though it'll traverse into a nested object before giving you the key for that object.
