JQuery queue()用法及代碼示例

queue()方法是jQuery中的內置方法，用於顯示要在所選元素上執行的函數隊列。在隊列中，一個或多個函數等待運行。

queue()方法可以與dequeue()方法一起使用。
一個元素可能有幾個隊列。通常，隻有一個默認的jQuery隊列。

用法:

$(selector).queue(queue_name)

參數：此方法接受可選的單個參數queue_name。用於設置隊列名稱。

<!DOCTYPE html>

        <!-- jQuery code to show the working of this method -->
        <script> 
            $(document).ready(function() { 
                $("p").click(function() { 
                    var div = $("div"); 
       
                    div.animate({ 
                        left: "+=200" 
                    }, 2000); 
                    div.animate({

                    }, "slow"); 
                    div.animate({

                    }, "slow"); 
                    div.animate({
