copied!<p>Ok, here is one approach to achieve this:</p> <p>Within your httpRequests success handler, attach a "timestamp" to your response:</p> <pre class="lang-js prettyprint-override"><code>// Assuming you are working with JSON data var response = JSON.parse(this.responseText); response.timestamp = new Date(); // For the purpose of this example, we persist our response to properties Ti.App.Properties.setObject('cachedResponse', response); </code></pre> <p>In your button eventListener we will check for the time that has passed</p> <pre class="lang-js prettyprint-override"><code>button.addEventListener('click', function() { var cachedResponse = Ti.App.Properties.getObject('cachedResponse', { timestamp: false }); if(cachedResponse.timestamp) { if(getHoursDiff(cachedResponse.timestamp, new Date()) > 24) { // Last request older than 24 hours, reload data } else { // Last request was within 24 hours, use cached data } } else { // No data has been saved yet, load Data } }); </code></pre> <p>This function calculates the time difference in hours</p> <pre class="lang-js prettyprint-override"><code>// http://blogs.digitss.com/javascript/calculate-datetime-difference-simple-javascript-code-snippet/ function getHoursDiff(earlierDate, laterDate) { var nTotalDiff = laterDate.getTime() - earlierDate.getTime(); var hours = Math.floor(nTotalDiff/1000/60/60); return hours; } </code></pre> <p><br><strong>Note</strong><br> This is not a complete example, you have to optimize and change the code to your needs.</p>
