javascript – 如何从多个数组中删除文件详细信息

这是每个循环的jquery代码,用于从数组中删除文件详细信息

var int_loop =  1;
        var display_removebutton="";
    $(upfiles).each(function(index,file) 
        {
            if(total_size > 1000) // size limit comparision
                 display_removebutton = "<img width='20px' style='cursor:pointer;' height='20px' id='remove_"+int_loop+"' src='images/DeleteRed.png' />"
            size = Math.round( file.size / 1024 );
            if(size > 1000)
            {
                if(size > 1024) 
                    size_display =  Math.round(size / 1024 * 100)/100 + ' mb';
                else
                    size_display = size + ' kb';    
                alert(file.name+"("+size+")"+" will be removed atomatically from list. As it exceeds limit.");
            }
            if(size > 1024) 
                    size_display =  Math.round(size / 1024 * 100)/100 + ' mb'; // converted to mb
            else
                    size_display = size + ' kb';    
            $('#total').append("<div id='div_selec"+int_loop+"'><b>File Name :</b> "+file.name + "<b> Size:</b>" + size_display + display_removebutton + "</div>" ); 
            $("#remove_"+int_loop).click(function() {

                var curr_id = this.id;
                var id = curr_id.substr(7);
                alert(id+'file name '+file.name);
               $("#div_selec"+id).empty();
                   upfiles.splice(index,1) //updated as the suggested in comment
//                    delete upfiles[id];
                alert(upfiles.length);

            });
             int_loop++;
    });

其实我在jquery PHP中实现拖放文件上传.在验证中,如果所有文件的总大小大于1000kb,则显示删除按钮,哪个用户必须删除一些文件

编辑2：

我在控制台日志中收到此错误：TypeError：upfiles.splice不是函数

编辑3：

upfiles来自这个jquery drop事件：

$( '#total' ).bind( 'drop',function(event) {

        event.stopPropagation();    
        event.preventDefault();

        if( upfiles == 0 )
                {
                upfiles = event.originalEvent.dataTransfer.files;

                                console.log(upfiles); // in this console log it is displaying `FileList [File,File,File]` File is nothing but the files which i have dropped in a div
                }
        else {
            if(confirm( "Drop: Do you want to clear files selected already?" ) == true) {
                upfiles = event.originalEvent.dataTransfer.files;
                $( '#filetoUpload' ).val('');
            }
            else
                return;
        }
        $( "#filetoUpload" ).trigger( 'change' );
});
