javascript - 如何在同一模式窗口中创建 3 个步骤？

Question

我需要在同一个模态窗口中创建 3 个步骤。

1. 寻找发起人。
2. 选择此发起人的事件。
3. 在此选定事件中安装设备。

PHP 代码加载步骤并在模式中向我显示一些内容，我尝试了各种形式但找不到解决方案，例如我尝试了 jQuery .load() 但无济于事。有什么帮助吗？谢谢!

我的模式:

<script>
    $('#exampleModal').on('show.bs.modal', function (event) {
        $( "#modal-content" ).load( "{{ path("agc_asistente_actividad", {"paso": "1"}) }}" );
    })
</script>

<div class="modal fade bs-example-modal-lg" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel">
    <div class="modal-dialog modal-lg">
        <div id="modal-content" class="modal-content">

        </div>
    </div>
</div>

Controller :

public function asistenteActividadAction($paso, Request $request){
        switch($paso){
            case "1" :
                return $this->render('AgcBackendBundle:asistente:paso1.html.twig');
            case "2" :
                $data = $request->request->get('data');
                $promotor = $data["promotor"];
                echo $promotor;
                return $this->render('AgcBackendBundle:asistente:paso2.html.twig');
            default:
                return $this->render('AgcBackendBundle:asistente:paso1.html.twig');
        }
    }

paso1.html.twig

<script>
    $('#next').click(function() {
        var data = [];
        data["promotor"] = $( "#recipient-promotor" ).val();
        $( "#modal-content" ).load( {{ path("agc_asistente_actividad", {"paso" : "2"}) }} + "/"+data);
    });
</script>
<div id="all">
<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" id="exampleModalLabel">Primer paso. <small>Localice al promotor titular de la actividad donde desea instalar el equipo</small></h4>
</div>
<div class="modal-body">
    <ol class="breadcrumb">
        <li class="active">Paso 1</li>
    </ol>
    <label for="recipient-promotor" class="control-label">DNI/CIF: </label>
    <input type="text" class="form-control" id="recipient-promotor">
</div>
<div class="modal-footer">
    <button type="button" class="btn btn-default" data-dismiss="modal">Cerrar</button>
    <button type="button" id="next" class="btn btn-primary">Buscar</button>
</div>
</div>

paso2.html.twig(不加载)

<script>
    $('#next').click(function() {
        var data = [];
        data["promotor"] = $( "#recipient-promotor" ).val();
        $( "document" ).load( {{ path("agc_asistente_actividad", {"paso" : "3"}) }} + "/"+data);
    });
</script>
<div id="all">
    <h1>prueba</h1>
<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" id="exampleModalLabel">Segundo paso. <small>Localice al promotor titular de la actividad donde desea instalar el equipo</small></h4>
</div>
<div class="modal-body">
    <ol class="breadcrumb">
        <li class="active">Paso 1</li>
    </ol>
    <label for="recipient-promotor" class="control-label">DNI/CIF: </label>
    <input type="text" class="form-control" id="recipient-promotor">
</div>
<div class="modal-footer">
    <button type="button" class="btn btn-default" data-dismiss="modal">Cerrar</button>
    <button type="button" id="next" class="btn btn-primary">Buscar</button>
</div>
</div>

Answer 1

将您的 3 个步骤放在同一模式下的不同 div 下(其中 2 个将始终隐藏)。然后您将使用一些快速的 jQuery 前进到下一步的 div。

需要 CSS:

.hideMe {display: none;}

需要 jQuery:

$("#btnEndStep1").click(function () {
    $("#step1").addClass('hideMe');
    $("#step2").removeClass('hideMe');
});
$("#btnEndStep2").click(function () {
    $("#step2").addClass('hideMe');
    $("#step3").removeClass('hideMe');
});
$("#btnEndStep3").click(function () {
    // Whatever your final validation and form submission requires
    $("#sampleModal").modal("hide");
});

保持简单和紧凑。这是一个例子 - https://jsfiddle.net/32rL6gxk/
