Unlock - Unlock Places: Code Samples

Code Samples

JavaScript

Simple search using a Javascript callback

The example below is an entire webpage, which requests a list of 10 features (by name) using a Javascript function. When the JSON is returned, it is wrapped in a callback function which is added to the page and executed. The callback displays the list of features and creates hyperlinks to each feature's footprint.

Demo

Source Code

<html>
<head>

<body>
    
        Feature name: 
        
        
    
    
</body>
</html>
