Answer 1

设置一个计数器：

var counter = 0;
$(".upload_add").click(function(){
    counter++;
    if(counter<7)
    $("#film_upload_side").append('<div class="photo_upload_button"> Shoose file to upload</div>');

});

Answer 2

var flag = 0;
$(".upload_add").click(function(){
    flag++;
    if(flag<=6)
    $("#film_upload_side").append('<div class="photo_upload_button"> Shoose file to upload</div>');

});

当它变为6时检查标志，然后停止追加。
