我误解了一个jQuery数组

Question

此代码无效

var next = $("#orders").find(".next");
            if (next.length == 1) {
                var address = $(next[0]).find(".directionsAddress");
                var destination = $(address[0]).text();
            }

假设找到一个带有＆＃34; next＆＃34;的等级的div。我知道它存在于页面上，然后在结果集数组的那一项中，将有一个div，其类名为directionsAddress。 ＆＃34;下一个＆＃34;数组以1的长度返回，所以看起来问题出在我的$（next [0]）。找到因为地址数组返回0长度而我正在制作某种类型的语法错误不明白。

你打算做这样的事吗？

＆＃13;

＆＃13;

$(document).ready(function() {
	alert($('#orders div.next:first div.directionsAddress:first').text());
});

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id = "orders">
    <div class="next">
        <div class="directionsAddress">THIS IS WHAT I WANT</div>
        <div class="directionsAddress">This is not the one I want</div>
    </div>
    <div class="next">
        <div class="directionsAddress">This is not the one I want</div>
    </div>
    <div class="next">
        <div class="directionsAddress">This is not the one I want</div>
    </div>
</div>
