Hi all, here a very fast example on how to read json data from file in Javascript,
here the content of *.htm file:
<!DOCTYPE html>
<html>
<head>
<title>LWebCode Javascript Read JSON from file</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.0/jquery.min.js"></script>
<script type="text/javascript" src="mydata.json"></script>
<script>
function ReadData()
{
var dataLstAz = JSON.parse(jsLstData);
alert(jsLstData.length);
for (var key=0, size=jsLstData.length; key<size; key++)
{
var obj = jsLstData[key];
liout = obj.Name + ", " + obj.Age + "<br/>";
$("#Output").append(liout);
}
}
$( document ).ready(function() {
ReadData();
});
</script>
</head>
<body>
<div id="Output">
</div>
</body>
</html>
Here the content of "mydata.json" file,
put this file in same folder of *.htm file, or change path in *.htm file:
jsLstData = '[{"Name":"MyName1","Age":"20"}, {"Name":"MyName2","Age":"22"}]';
//End of file "mydata.json"
Now simply open *.htm file in browser and you'll get this output:
MyName1 20
MyName2 22
That's it, hope it helps
