var crop = new ImgCrop({
areaEl: "#J_CropBox",
initialXY: [10, 10],
initWidth: 200,
initHeight: 200,
minHeight: 100,
minWidth: 100,
areaWidth: 300,
areaHeight: 300,
//previewEl: "#J_PrevBox_75",//不需要不配置
//viewWidth: 75,
//viewHeight: 75,
previewArrayParam: [
{ viewEl: '#J_PrevBox_180', viewWidth: 180, viewHeight: 180 },
{ viewEl: '#J_PrevBox_75', viewWidth: 75, viewHeight: 75 },
{ viewEl: '#J_PrevBox_50', viewWidth: 50, viewHeight: 50 },
{ viewEl: '#J_PrevBox_25', viewWidth: 25, viewHeight: 25 }],

});

    crop.on('imgload drag resize', function () {
        S.one('#J_InfoBox').val(crop.toString(4));
        //S.log(S.JSON.stringify(crop.getOriginalSize()));
        //S.log(S.JSON.stringify(crop.getDisplaySize()));
    });
    crop.render();

修改并不多
