Ajax异步多图上传

$(“#upload-input”).change(function(){
var data = new FormData();

    //每张图片添加到FormData
    $.each($("#upload-input")[0].files,function(i,file){
        data.append("file"+i,file);
    });

    //发送数据
    $.ajax({
        url:'{:url("Upload/uploads")}',
        type:'post',
        data:data,
        dataType:'json',
        cache: false,
        contentType: false,
        processData: false,
        // contentType: false 和processData: false，这两个参数是为了设置ajax对file文件对象进行序列化
        success:function(data){
            $("#datas").attr("value",data.images);
        },
        error:function(){
            alert('上传出错');
        }
    });

});
