jQuery show/hide 基于 select （调查模式）

Question

我想根据信息图时间改进此处提供的代码 https://jsfiddle.net/comprido/dcgjzfph/4/：对我来说最好的 T 恤打印技术是什么，以便在我的客户选择打印选项之前将这些问题传递给他们。我确信编码可以改进......任何手？

Answer 1

随便玩玩，你可以把它压缩成一个循环

document.querySelectorAll('select').forEach((item)=>{
  item.addEventListener('change', (function(){
    document.getElementById(item.value).style.display = 'block';
    $("option:selected").removeAttr("selected");
    document.getElementById('question'+(/[0-9]/gi.exec(item.id)[0])).style.display = 'none';
  }));
});

当您添加更多问题时，它应该会起作用。 ES6 风格和 Jquery 的奇怪组合现在（可能不适用于 ie）。我会远离 JQ，现在真的不需要它，学习 JS 可能更好

function resetQuestions() {
    document.querySelectorAll("[id^='question']").forEach((element)=>{
        element.style.display = "none";
    });
    document.getElementById("question1").style.display = "block"; 
}

Answer 2

不确定这是否是最佳解决方案，但这是我所做的。

$(function () {
    // Number of questions
    const numbersSelect = [1, 2, 3, 4, 5, 6, 7, 11];
    $.each(numbersSelect, (index, value) => {
        $(`#select${value}`).change(function () {
            $('#' + $(this).val()).show();
            $("option:selected").removeAttr("selected");
            $(`#question${value}`).hide();
        });
    });

    // show q1, others hide
    const numbersHide = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13];
    $('input[name="startover"]').on('click', (e) => {
        e.preventDefault();
        $.each(numbersHide, (index, value) => {
            (value === 1) ? $(`#question${value}`).show() : $(`#question${value}`).hide();
        });
    })
});
