是内存警告来每次你点击按钮？ – dhaval 2012-07-05 16:55:46

答

你默认为它使用了太多的内存数据网址的回报。切换到文件uri。

function getPhoto(imageData) { 
    var smallImage = document.getElementById('smallImage'); 

    smallImage.style.display = 'block'; 

    smallImage.src = imageData; 
} 

function capturePhoto() { 
    navigator.camera.getPicture(getPhoto, onFail, { quality: 50, 
     destinationType: destinationType.FILE_URI }); 
}
