I've been trying to learn how to use ajax however I can't seem to get any result back.
HTML code
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Bootstrap 101 Template</title>
<!-- Bootstrap -->
<link href="css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script src="functions.js"></script>
<div class="container">
<form>
<div class="form-group row">
<label for="foodLabel" class="col-sm-2 col-form-label">Search For Food Label</label>
<div class="col-sm-10">
<input class="form-control" type="search" id="foodLabel">
</div>
</div>
<div class="form-group row">
<div class="col-sm-offset-2 col-sm-10">
<button class="btn btn-default" type="submit" id="submit" onclick="getFormData()">Submit</button>
</div>
</div>
</form>
</div>
</body>
</html>
And this is my js file
function getFormData(){
var foodLabel=document.getElementById('foodLabel').value;
var searchURL = buildSearchURL(foodLabel);
//console.log(searchURL);
$.ajax({
url: searchURL,
type: "GET",
dataType: "json",
success: function(data){
alert("success");
},
error: function(){
alert("failure");
}
});
}
function buildSearchURL(label){
var searchURL = "http://api.nal.usda.gov/ndb/search/?format=json&q=" + label + "&sort=n&max=25&offset=0&api_key=h9TKX24GP1vDETSUfQc2hU8b4w3orECoocoQFeE7";
return searchURL;
}
I've tried multiple variations in trying to make this work but all I'm getting is error function back. Would you be able to help me out here?
If I enter, for example, "chips" into input box, it would generate this URL: http://api.nal.usda.gov/ndb/search/?format=json&q=chips&sort=n&max=25&offset=0&api_key=DEMO_KEY
Which would be a valid json (checked)
