获取系统相册路径xz

document.getElementById("photograph").addEventListener("tap", function() {
plus.gallery.pick(
function(path) {
//alert(path);
//设置img的路径
//把图片base64编码 注意：这里必须在onload事件里执行！这给我坑的不轻
var img_my = document.createElement("img");
img_my.src = path;
$('#myanswer').append(img_my);

                img_my.onload = function() {  
                    var data = getBase64Image(img_my); //base64编码  
                    var newImgbase = data.split(",")[1]; //通过逗号分割到新的编码  
                    imgArray.push(newImgbase); //放到imgArray数组里面  
                    //img_my.off(); //关闭加载  
                    console.log(imgArray);  
                    console.log(imgArray.length);  
                }  
            },  
            function(e) {  
                mui.toast('取消选择');  
            });  
    });
