If I have a JSON file named names.json with:
{"employees":[ {"firstName":"Anna","lastName":"Meyers"}, {"firstName":"Betty","lastName":"Layers"}, {"firstName":"Carl","lastName":"Louis"}, ]} How can I use its content in javascript?

Projects In JavaScript & JQuery To load JSON data using jQuery, use the getJSON() and ajax() method. The jQuery. getJSON( ) method loads JSON data from the server using a GET HTTP request. data − This optional parameter represents key/value pairs that will be sent to the server.
Use the JavaScript function JSON. parse() to convert text into a JavaScript object: const obj = JSON. parse('{"name":"John", "age":30, "city":"New York"}');
If you need to parse a JSON string that returns a dictionary, then you can use the json. loads() method. If you need to parse a JSON file that returns a dictionary, then you can use the json. load() method.
An example how to do this could be:
<html> <head> <script type="text/javascript" src="http://code.jquery.com/jquery.min.js"></script> <script type="text/javascript"> $(function(){ $.getJSON('names.json',function(data){ console.log('success'); $.each(data.employees,function(i,emp){ $('ul').append('<li>'+emp.firstName+' '+emp.lastName+'</li>'); }); }).error(function(){ console.log('error'); }); }); </script> </head> <body> <ul></ul> </body> </html> You can simply include a Javascript file in your HTML that declares your JSON object as a variable. Then you can access your JSON data from your global Javascript scope using data.employees, for example.
index.html:
<html> <head> </head> <body> <script src="data.js"></script> </body> </html> data.js:
var data = { "employees": [{ "firstName": "Anna", "lastName": "Meyers" }, { "firstName": "Betty", "lastName": "Layers" }, { "firstName": "Carl", "lastName": "Louis" }] } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
