Question

我想将所有字符串放在一个数组中然后查看jquery选择器是否包含任何这些stings，如果是，请执行一些代码。

创建我的数组：

var usa_destinos_direct = ["York-Todos", "York-EWR", "Florida-Fort", "Florida-Todos", "Los Angeles", "Oakland" ];

然后检查它是否在jquery选择器中：

if ($("div.pagetitlebox h1:contains(usa_destinos_direct)")){    
    $("div").css("background", "yellow");
}

我哪里错了？

Answer 1

jQuery不会将usa_destinos_direct视为变量，而是将您想要在h1中搜索的字符串。

您应该遍历目标数组：

usa_destinos_direct.forEach(function (str) {
    if ($("div.pagetitlebox h1:contains(" + str + ")")){
        $("div").css("background", "yellow");
    }
};

Answer 2

您可以映射该数组以构建所需的选择器：

var containsSelector = usa_destinos_direct.map(d => `h1:contains('${d}')`).join(',');

var usa_destinos_direct = ["York-Todos", "York-EWR", "Florida-Fort", "Florida-Todos", "Los Angeles", "Oakland" ];
var containsSelector = usa_destinos_direct.map(d => `h1:contains('${d}')`).join(',');

$(`div.pagetitlebox ${containsSelector}`).css("background", "yellow");

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="pagetitlebox">
<h1>York-Todos</h1>
<h1>Florida-Fort</h1>
<h1>Venezuela</h1>
</div>
