Question

我正在尝试将数组传递给我的.each JQuery代码，但它只传递数字0,1,2,3 ......而不是字符串值。

我定义变量的代码是：

var accessoriesCats = [ 'Beaded Accessories', 'Cufflinks', 'Flip Flops', 'Floral Accessories', 'Foot Jewelry', 'Hair Accessories', 'Hankies', 'Jewelry', 'Leg Garters', 'Purses', 'Shoe Stickers', 'Something Blue', 'Tiaras', 'Totes' ];

这是我的整个代码：

    <script>
    if (window.location.href.indexOf("category-s/2022.htm") != -1) {
            var accessoriesCats = [ 'Beaded Accessories', 'Cufflinks', 'Flip Flops', 'Floral Accessories', 'Foot Jewelry', 'Hair Accessories', 'Hankies', 'Jewelry', 'Leg Garters', 'Purses', 'Shoe Stickers', 'Something Blue', 'Tiaras', 'Totes' ];
                $('#content_area > table:nth-child(6) > tbody > tr > td > table:nth-child(1) > tbody > tr > td > table > tbody').find('a').each(function(accessoriesCats){
                            $(this).append('<span class="promo__text">' + accessoriesCats + '</span>');
                            $(this).removeClass('smalltext colors_text').addClass('subcatRollover');
            });
        }
</script>

基本上我想要的第一个.append是：

<span class="promo__text">Beaded Accessories</span>

但我得到了

<span class="promo__text">0</span>

Answer 1

使用此：

<script>
    if (window.location.href.indexOf("category-s/2022.htm") != -1) {
        var accessoriesCats = [ 'Beaded Accessories', 'Cufflinks', 'Flip Flops', 'Floral Accessories', 'Foot Jewelry', 'Hair Accessories', 'Hankies', 'Jewelry', 'Leg Garters', 'Purses', 'Shoe Stickers', 'Something Blue', 'Tiaras', 'Totes' ];
        $('#content_area > table:nth-child(6) > tbody > tr > td > table:nth-child(1) > tbody > tr > td > table > tbody').find('a').each(function(i){
                $(this).append('<span class="promo__text">' + accessoriesCats[i] + '</span>');
                $(this).removeClass('smalltext colors_text').addClass('subcatRollover');
        });
    }
</script>

根据文档，数组中.each的第一个参数是索引，第二个是项目（http://api.jquery.com/jquery.each/）

.each(function(index, accessoriesCats) {
                ^^^ADD INDEX

JQuery传递数组字符串
