Question

我有通过Bootstrap开发的定价表和1个简单的下拉式Javascript。

如果用户选择“选项1”，那么我怎么能这样做，那么当前说“获得100封电子邮件”的项目符号更改为“获得300封电子邮件”和“每天最大电子邮件数：3”更改为“最大电子邮件数”每天：6“。

如果用户选择“选项2”，则当前显示“获得100个电子邮件”的项目符号点将更改为“获得600个电子邮件”和“每天最大电子邮件数：3”更改为“每天最大电子邮件数：10” ”

不幸的是我不是Javascript专家（我在JS中非常糟糕）所以我将非常感谢您的帮助。

$(document).ready(function () {
    $(".btn-select").each(function (e) {
        var value = $(this).find("ul li.selected").html();
        if (value != undefined) {
            $(this).find(".btn-select-input").val(value);
            $(this).find(".btn-select-value").html(value);
        }
    });
});

$(document).on('click', '.btn-select', function (e) {
    e.preventDefault();
    var ul = $(this).find("ul");
    if ($(this).hasClass("active")) {
        if (ul.find("li").is(e.target)) {
            var target = $(e.target);
            target.addClass("selected").siblings().removeClass("selected");
            var value = target.html();
            $(this).find(".btn-select-input").val(value);
            $(this).find(".btn-select-value").html(value);

Answer 1

这将有希望工作（一个普通的JavaScript解决方案）：

var cells = document.querySelectorAll('tr td p');
function opt1() {
  rows[0].innerHTML = "Gain 300 Emails";
  rows[3].innerHTML = "Max Emails per Day: 6";
}

function opt2() {
  rows[0].innerHTML = "Gain 600 Emails";
  rows[3].innerHTML = "Max Emails per Day: 10";
}

function opt3() {
  rows[0].innerHTML = "Gain 900 Emails";
  rows[3].innerHTML = "Max Emails per Day: 15";
}

function opt4() {
  rows[0].innerHTML = "Gain 1500 Emails";
  rows[3].innerHTML = "Max Emails per Day: 20";
}

var options document.querySelectorAll('.btn-select-arrow ul li');
options[0].onclick = opt1():
options[1].onclick = opt2():
options[2].onclick = opt3():
options[3].onclick = opt4():

Answer 2

您可以尝试以下代码。我已经更新了有关点击功能的文档。希望你得到你想要的东西：

$(document).on('click', function (e) {
    var target = $(e.target).closest(".btn-select");
    if (!target.length) {
        $(".btn-select").removeClass("active").find("ul").hide();
    }
    if (!$(e.target).hasClass('btn-select-value') && $(e.target).parents('.btn-select-light').length > 0) {
        var gainEmailTxt = "", maxEmailPerDayTxt = "";
        switch ($(e.target).text()) {
            case "Option 1":
                gainEmailTxt = "Gain 300 Emails";
                maxEmailPerDayTxt = "Max Emails per Day: 6";
                break;
            case "Option 2":
                gainEmailTxt = "Gain 600 Emails";
                maxEmailPerDayTxt = "Max Emails per Day: 10";
                break;
            case "Option 3":
                gainEmailTxt = "Gain 900 Emails";
                maxEmailPerDayTxt = "Max Emails per Day: 15";
                break;
            case "Option 4":
                gainEmailTxt = "Gain 1500 Emails";
                maxEmailPerDayTxt = "Max Emails per Day: 20";
                break;
            default:
                gainEmailTxt = "Gain 100 Emails";
                maxEmailPerDayTxt = "Max Emails per Day: 3";
                break;
        }

        $('.table-premium td:eq(0) p').text(gainEmailTxt);
        $('.table-premium td:eq(3) p').text(maxEmailPerDayTxt);
    }
});

表内容更改取决于下拉选项
