There are quite a number of syntax errors, for example , equal operator should be "==" not "=". There are also missing quotes in the json file. However, I shall not go into such matters. Your question is really about how to loop thru the array of json objects and access their properties (keys).
Try and adapt from this demo:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
$.getJSON("json1.json", function(result){
$.each(result, function(i, obj){
$("div").append(obj.first + " " + obj.last + " " + obj.desc + " " + "<br>");
});
});
});
});
</script>
</head>
<body>
<button>Get JSON data</button>
<div></div>
</body>
</html>
Assuming the "json1.json" is in the same directory of the html file and contains:
[
{"first":"fgdfb", "last":"dfghdfgh", "desc":"jjif"},
{"first":"jdtyhjn", "last":"hmbnmgh", "desc":"hfhhfyif"},
{"first":"fgbnfgjthj", "last":"tewgsdfgngh", "desc":"argrayif"},
{"first":"kuykyky", "last":"bfbffc", "desc":"lykghif"},
{"first":"thefirstname", "last":"dsfhngh", "desc":"pgkkgff"},
{"first":"ghjjhb", "last":"fdasfgh", "desc":"nfhdfhjif"},
{"first":"ohhklhjb", "last":"qsdwdgh", "desc":"vfrfeif"}
]
