copied!<p>"if (progressEvent.lengthComputable) {" has no matching closing bracket.</p> <p>It could be that's broken subsequent methods onUploadSuccess and onUploadError. Or perhaps that's just a typo in your question.</p> <p>Incidentally, it might be good practice to save a FileTransfer reference for each imageURI, rather than using a global reference to a single FileTransfer. Then you could upload multiple photos at once, and still retain the ability to cancel each upload separately, e.g.</p> <pre><code>// basic implementation of hash map of FileTransfer objects // so that given a key, an abort function can find the right FileTransfer to abort function SimpleHashMap() { this.items = {}; this.setItem = function(key, value) { this.items[key] = value; } this.getItem = function(key) { if (this.hasItem(key)) { return this.items[key]; } return undefined; } this.hasItem = function(key) { return this.items.hasOwnProperty(key); } this.removeItem = function(key) { if (this.hasItem(key)) { delete this.items[key]; } } } var fileTransferMap = new SimpleHashMap(); </code></pre> <p>...then in uploadPhoto after creating a new FileTransfer:</p> <pre><code>// register this object so that abort can find it fileTransferMap.setItem(imageURI, ft); </code></pre> <p>...then pass the imageURI in your cancel button:</p> <pre><code>function onStopUploadBtn(imageURI) { var ft = fileTransferMap.getItem(imageURI); if (ft) { console.log('Aborting'); ft.abort(onUploadSuccess, onUploadError); } } </code></pre> <p>...and remember to remove the ft from the map when download is complete, or upon error:</p> <pre><code>fileTransferMap.removeItem(imageURI); </code></pre>
