jQuery的追加（）限制

Question

大家好我有這個scripts，我想追加只發生六次

$(".upload_add").click(function(){ 
    $("#film_upload_side") 
    .append('<div class="photo_upload_button"> Shoose file to upload</div>'); 
}); 

Answer 1

設置一個計數器：當它成爲6

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>'); 

}); 

校驗標誌，然後停止追加。
