雨果-简码-模态窗口

问题描述

我正在使用Hugo 0.74版

我建立了一个简码：

使用我指定的文本创建按钮
打开一个由getform.io组成的模态窗口

一切正常，请期待一个小故障：

我必须按两次按钮才能打开模式窗口

我已经在Chrome，Firefox和Edge以及所有需要单击两次以将其打开的地方进行了尝试。

我要去哪里错了？

{{$text := .Get "text"}}


<button id="id_reachout" style="background:#28A745;color:white;font-family: 'Varela Round';" onClick="showModal();"> {{$text}}   </button>

<div id="myModal" class="modal">
    <!-- Modal content -->
    <div class="modal-content">
        <span class="close">&times;</span>
        <div class="row">
            <div class="modal-column" style="border: 5px double red">
                <img src="/img/MyModal.png" alt="Alternate text" class="modal-image">
            </div>
            <div class="modal-column">
                <form action="https://getform.io/f/4804d94b-8f1q-4a05-a679-7da0ba070952" method="POST">
                    <label for="id_name" class="modal-label"> Name </label>
                    <input type="text" name="name" id="id_name" class="modal-input">
                    <label for="id_email" class="modal-label"> Email </label>
                    <input type="email" name="email" id="id_email" class="modal-input">
                    <label for="id_message" class="modal-label"> Message </label>
                    <textarea name="message" id="id_message" class="modal-textarea"> </textarea>
                    <input id="id_submit" class="modal-submit" name="submit" type="submit" value="Submit">
                </form>
            </div>
        </div>
    </div>
</div>

在MyArticle.md文件中，我将此短代码称为：

{{<modal_button text="I have some more questions related to assets!">}}

我的custom.js文件是：

function showModal() {

    // Get the modal
    var modal = document.getElementById("myModal");

    // Get the button that opens the modal
    var btn = document.getElementById("id_reachout");

    // Get the <span> element that closes the modal
    var span = document.getElementsByClassName("close")[0];

    // When the user clicks on the button,open the modal
    btn.onclick = function () {
        modal.style.display = "block";
    }

    // When the user clicks on <span> (x),close the modal
    span.onclick = function () {
        modal.style.display = "none";
    }

    // When the user clicks anywhere outside of the modal,close it
    window.onclick = function (event) {
        if (event.target == modal) {
            modal.style.display = "none";
        }
    }
}

最后这是我的css文件：

/* The Modal (background) */
.modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    left: 0;
    top: 0;
    width: 100%; /* Full width */
    height: 100%; /* Full height */

    background-color: rgb(0,0); /* Fallback color */
    background-color: rgba(0,0.4); /* Black w/ opacity */
}

/* Modal Content/Box */
.modal-content {

    width: 80%; /* Could be more or less,depending on screen size */
    height: 80%;
}

.close {

        cursor: pointer;
    }

.modal-label {
    display:block;
    margin-top:20px;
    letter-spacing: 2px;
    font-weight:bold;
}

.modal-input {

}

    .modal-input:focus {

    }

    font-size: 0.9em;
    color: #3a3a3a;
    -moz-border-radius: 5px;
    -webkit-border-radius: 5px;
    border-radius: 5px;
}

#submit {
    width: 127px;
    height: 60px;
    text-indent: -9999px;
    border: none;
    cursor: pointer;
}
    #submit:hover {
        opacity: .9;
    }

.row {
    display: flex;
}

.modal-column {
    flex:50%;
    padding:10px;
}

.left-column{
    font-size:2rem;

}

解决方法

当用户单击按钮时，您正在呼叫showModal()。但是，该功能会添加另一个 onclick = function-要求用户单击两次。

showModal()应该立即调用用于显示模式的逻辑，而不是附加另一个onclick功能。

快速修复：

替换：


btn.onclick = function () {
    modal.style.display = "block";
}

使用：

if (modal.style.display != "block") {
   modal.style.display = "block";
}

Demo -如果需要，您可以省略if检查，如果需要，只需将onclick替换为modal.style.display = "block";。

function showModal() {

    // Get the modal
    var modal = document.getElementById("myModal");

    // Get the button that opens the modal
    var btn = document.getElementById("id_reachout");

    // Get the <span> element that closes the modal
    var span = document.getElementsByClassName("close")[0];
    
    if (modal.style.display != "block") {
        modal.style.display = "block";
    }

    // When the user clicks on <span> (x),close the modal
    span.onclick = function () {
        modal.style.display = "none";
    }

    // When the user clicks anywhere outside of the modal,close it
    window.onclick = function (event) {
        if (event.target == modal) {
            modal.style.display = "none";
        }
    }
}

/* The Modal (background) */
.modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    left: 0;
    top: 0;
    width: 100%; /* Full width */
    height: 100%; /* Full height */
    overflow: auto; /* Enable scroll if needed */
    background-color: rgb(0,0); /* Fallback color */
    background-color: rgba(0,0.4); /* Black w/ opacity */

感谢贾斯汀。它为我指明了正确的方向，下面的代码解决了这个问题：

function showModal() {

    // Get the modal
    var modal = document.getElementById("myModal");

    modal.style.display = "block";
}

/* Added a close Modal */

function closeModal() {

    // Get the <span> element that closes the modal
    var modal = document.getElementById("myModal");
    modal.style.display = "none";

}

在html中，我对跨度进行了很小的更改-我添加了onClick = closeModal（）：

<div id="myModal" class="modal">
    <!-- Modal content -->
    <div class="modal-content">
        <span class="close" onclick="closeModal();">&times;</span>
        <div class="row">
            <div class="modal-column" style="border: 5px double red">
                <img src="/img/PlanyourmoneyModal.png" alt="Financial Planning,Goal Planning" class="modal-image">
            </div>
            <div class="modal-column">
                <form action="https://getform.io/f/4804d94b-8f1b-4a05-a679-7da0ba070952" method="POST">
                    <label for="id_name" class="modal-label"> Name </label>
                    <input type="text" name="name" id="id_name" class="modal-input">
                    <label for="id_email" class="modal-label"> Email </label>
                    <input type="email" name="email" id="id_email" class="modal-input">
                    <label for="id_message" class="modal-label"> Message </label>
                    <textarea name="message" id="id_message" class="modal-textarea"> </textarea>
                    <input id="id_submit" class="modal-submit" name="submit" type="submit" value="Submit">
                </form>
            </div>
        </div>
    </div>
</div>
