javascript - 如何删除除您单击的类(class)之外的所有类(class)？

Question

当我单击链接时，此功能就会启动。它需要删除具有属性 [data-route] 的元素上的所有“.is-active”类。并在与我单击的链接连接的 [data-route] 元素上添加“.is-active”类。

    toggle: function(section){
        var sections = document.querySelectorAll('[data-route]');
        for (i = 0; i < sections.length; i++){
            document.querySelector('[data-route]').classList.remove('is-active');
        }
        document.querySelector(section).classList.add('is-active');
    }

但这行不通。它不会删除类(class)吗？

附注它必须是原生 JavaScript。

Answer 1

toggle: function(section){
    var sections = document.querySelectorAll('[data-route]');
    for (i = 0; i < sections.length; i++){

        sections[i].classList.remove('is-active');

        // querySelectorAll return an array of dom elements, u can access them directly.

    }

    // I suppose in your case that ' section ' variable is the clicked element so :

    section.classList.add('is-active')

   // if not you have to store the dom element from the event, and add the class here.

}
