所以我试图在我的产品列表中构建一个具有不同变体的快速产品。该产品有一组avaialble选项,使用jQuery从select选项中收集,传递到输入字段然后提交到购物车。产品通过循环列出。当我在单个产品页面上时,它工作正常,因为所有选项值都是必需的。
但是,在产品列表中,它会从所有产品中获取选项并将其传递给所有提交字段。如何确定jquery函数的范围,以便一次只处理一个产品
在下面的示例中,我希望该字段仅包含与产品相关的选项选项中的值。两种产品选择都没有评估价值。
$(document).ready(function() {
$(".variant-selected")
.change(function() {
var str = "";
$("select option:selected").each(function() {
str += $(this).val() + ".";
});
$("input[name='variant']").val(str.slice(0, -1));
})
.trigger("change");
});

<select class="variant-selected" name="select1">
