如何使用 jQuery/AJAX 更改模式的文本？

Question

虽然这个问题之前被问过几次，但似乎没有一个答案对我有帮助。所以我又问了...

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，带有一个next 和一个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。我认为这看起来不专业。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，而不必继续打开和关闭模态。但是，我不确切知道如何做到这一点。我假设这可以通过 jQuery 和 AJAX 完成。我将附上我的代码。任何反馈表示赞赏。

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

<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-->

h4和div应该替换成这个modal的h4和div

<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式，这变得多余。简单地替换文本会更有效。

$(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');
    });

});

如果您有一个静态页面并且想要在不关闭下一步按钮上的模式对话框的情况下更改内容，您需要将内容静态存储在文件中。

我提出以下解决方案：

var eleToDisplay = ["next1", "next2"];
var indexOfEles = 0;

$('#btn').click(function () {
  $("#dialog").dialog({
    title: "Change text on Next without closing ",
    resize: "auto",
    modal: true,
    buttons: {
      "Next": function() {
        $(this).html($('#' + eleToDisplay[indexOfEles]).html());
        indexOfEles = ((indexOfEles + 1) >= eleToDisplay.length) ? 0 : indexOfEles + 1;
      },
      Close: function() {
        $(this).dialog( "close" );
      }
    },
    open: function() {
      $(this).html($('#' + eleToDisplay[indexOfEles]).html());
      indexOfEles = ((indexOfEles + 1) >= eleToDisplay.length) ? 0 : indexOfEles + 1;
      $(this).parent().find('.ui-button:last').focus();
    }
  });
});

body {
  font-family: "Trebuchet MS", "Helvetica", "Arial",  "Verdana", "sans-serif";
  font-size: 62.5%;
}

你可以按照这个例子来制作它（需要适应你的代码，但这个想法应该可行）。

HTML（模态）：

<div id="container">
  <p>this is the first text in the modal</p>
</div>
<input id="nextBtn" type="button" value="NEXT"/>

jQuery:

$(document).ready(function() {
   var objPos = 1;
   var ajaxReturnObj = ["this is the first text in the modal","this is the second text in the modal","this is the third text in the modal"];
   $('#nextBtn').click(function(){
      $('#container p').text(ajaxReturnObj[objPos]);
      objPos++;
   });
});
