viewMode: 1,
crop: function(e) {
// console.log(e);
}
});
//裁剪完压缩方法
$(‘.caijian’).on(‘click’, function() {
var result = $(‘.caijianpic’).cropper(“getCroppedCanvas”, {
width: 750,
height: 1000
});
var base64img = result.toDataURL(“image/jpg”);
$(‘.showpic’).attr(‘src’, base64img);
})
$(‘.quxiaocaijian’).on(‘click’, function() {
$(‘.image’).cropper(“destroy”)
})
})

ps:这个案例是裁剪中状态的
