如何使用jQuery/AAJAX更改模态的文本

虽然这个问题以前被问过几次，但似乎没有一个答案对我有帮助。因此我再次问它。。。

我正在构建一个没有后端（没有服务器调用等）的网站的前端。我有一个显示内容的模式，带有next和close按钮。我最初的设计是，当按下next按钮时，它会关闭打开的模式，并打开一个具有不同内容的新模式。我觉得这看起来不专业。我希望当用户按下next按钮时，它会获取下一个模态的内容，并将其显示在打开的模态上，而不必一直打开和关闭模态。然而，我不知道该怎么做。我假设这可以通过jQuery和AJAX实现。我会附上我的代码。如有任何反馈，我们将不胜感激。

这是开放模态。当用户点击next时，我希望用下一个模态替换<h4 class="modal-title>和<div class="modal-body>的内容。

<div class="modal fade protein-modal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <!-- PROTEIN MODAL START-->
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                    <h4 class="modal-title"> Lean Protien </h4><!--CHANGE THIS WITH NEXT MODAL-->
                </div>
                <div class="modal-body"><!--CHANGE THIS WITH NEXT MODAL-->
                    <p>
                        At every meal, divide your plate into three equal sections. On one-third of the plate put some low-fat protein that is no larger or thicker than the palm of your hand (that’s because some hands are larger than others).
                    </p>
                    <p>
                        This doesn’t have to be animal protein, but it has to be protein-rich. For vegans this means either extra-firm tofu or soy imitation-meat products. For lacto-ovo vegetarians, it can also include dairy and egg protein-rich sources in addition to vegan sources of protein. For omnivores, the choice of proteins is even wider.
                    </p>
                    <div class="modal-image">
                        <img src="img/1-3plate1.png"/>
                    </div>
                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-primary zero-border" data-dismiss="modal">Close</button>
                    <button type="button" class="btn btn-success zero-border btn-next-slide-1" data-dismiss="modal">Next</button>
                </div>
            </div>
        </div>
    </div> <!-- PROTEIN MODAL END-->

这个模式的h4和div应该被替换

<div class="modal fade colorful-culinary-modal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <!-- COLORFUL-CULINARY MODAL START-->
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                    <h4 class="modal-title">Colorful Carbohydrates</h4>
                </div>
                <div class="modal-body">
                    <p>
                        Next, fill the other two-thirds of your plate with colorful carbohydrates, primarily non-starchy vegetables and small amounts of fruits to balance the protein as shown below.
                    </p>
                    <p>
                        Here are two very practical hints when it comes to carbohydrates. First, the more white (white bread, white pasta, white rice, and white potatoes) you put on your plate, the more inflammation you are going to create. Second, the more non-starchy vegetables you consume and the fewer grains and starches you eat (ideally none), the better the results. Scientifically, it’s called lowering the glycemic load of the meal.
                    </p>
                    <div class="modal-image">
                        <img src="img/2-3plate1-1.png"/>
                    </div>
                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-primary zero-border" data-dismiss="modal">Close</button>
                    <button type="button" class="btn btn-success zero-border btn-next-slide-2" data-dismiss="modal">Next</button>
                </div>
            </div>
        </div>
    </div> <!-- COLORFUL-CULINARY MODAL END-->

目前，我只是打开和关闭模态，这是多余的。简单地替换文本会更有效率。

$(document).ready(function()
{
    $('.colorful-culinary-button').click(function()
    {
        $('.colorful-culinary-modal').modal('show');
    });
    $('.protein-button').click(function()
    {
        $('.protein-modal').modal('show');
    });
    $('.fat-button').click(function()
    {
        $('.fat-modal').modal('show');
    });
    $('.btn-next-slide-1').click(function()
    {
        $('.colorful-culinary-modal').modal('show');
    });
    $('.btn-next-slide-2').click(function()
    {
        $('.fat-modal').modal('show');
    });
    $('.diet-builder-button').click(function()
    {
        $('.diet-builder-modal').modal('show');
    });
});
