hTML Modal Popup

Alles,

So erstellen Sie ein einfaches modales Popup für den folgenden Code. Wenn Sie auf den Hintergrund klicken, sollte das modale Popup nicht verschwinden.

<html>
<input type="textarea"></input>
</html>

Vielen Dank.........

Hier ist ein einfaches JavaScript-Beispiel:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title>Basic modal demo</title>
        <style type="text/css">
            body { margin: 0; }
            #shade, #modal { display: none; }
            #shade { position: fixed; z-index: 100; top: 0; left: 0; width: 100%; height: 100%; }
            #modal { position: fixed; z-index: 101; top: 33%; left: 25%; width: 50%; }
            #shade { background: silver; opacity: 0.5; filter: alpha(opacity=50); }
        </style>
    </head>
    <body>
        <div id="shade"></div>
        <div id="modal">
            <textarea rows="5" cols="25"></textarea>
            <button id="close">Close</button>
        </div>

        <p>
            <button id="start">Start</button>
        </p>
        <script type="text/javascript">
            var modal= document.getElementById('modal');

            document.getElementById('start').onclick= function() {
                modal.style.display=shade.style.display= 'block';
            };
            document.getElementById('close').onclick= function() {
                modal.style.display=shade.style.display= 'none';
            };

            // This code is a workaround for IE6's lack of support for the
            // position: fixed style.
            //
            if (!('maxHeight' in document.body.style)) {
                function modalsize() {
                    var top= document.documentElement.scrollTop;
                    var winsize= document.documentElement.offsetHeight;
                    var docsize= document.documentElement.scrollHeight;
                    shade.style.height= Math.max(winsize, docsize)+'px';
                    modal.style.top= top+Math.floor(winsize/3)+'px';
                };
                modal.style.position=shade.style.position= 'absolute';
                window.onscroll=window.onresize= modalsize;
                modalsize();
            }
        </script>

    </body>
</html>

Es gibt verschiedene Verbesserungen, die Sie von dort aus vornehmen können, z. B. iframe-Hacks zum Beheben von IE z-Indizierung oder zum Einkapseln in wiederverwendbare Objekte. Dies ist jedoch die grundlegende Vorgehensweise.

jQueryUI hat ein modales Dialog-Plugin. Sie geben die Kontrolle nicht einfach durch Anklicken des Hintergrunds frei, wie Sie es gewünscht haben: http://jqueryui.com/demos/dialog/#modal

<a href="#" class="showModal">Show Modal Box</a>
<div id="modalContents" style="display:none;">
  <textarea>Hello World</textarea>
</div>

-

$(".showModal").click(function(e){
  e.preventDefault();
  $("#modalContents").dialog({bgiframe: true, height: 140, modal: true});
});

html5 auf Chrome hat das <dialog>-Element. Experimentiere damit

mishal153

sie können auch native HTML5.1-Dateien verwenden. Derzeit wird das Dialogelement nur in Chrome 37+, Safari 6+ und Opera 24+ unterstützt.

var dailog = document.getElementById("dialog"); 

function openModal() { 
   // dailog.show(); 
      dailog.showModal();
} 

function closeModal() { 
    dailog.close(); 
} 
#dialog{width:300px;}
.right{float:right}
<button onclick="openModal()">Show dialog</button>


<dialog id="dialog">This is a dialog window<br/><br/><br/>
<button onclick="closeModal()" class="right">Close</button>
</dialog>

HTML:

<!-- Trigger/Open The Modal -->
<button id="myBtn">Open Modal</button>

<!-- The Modal -->
<div id="myModal" class="modal">

  <!-- Modal content -->
  <div class="modal-content">
    <span class="close">&times;</span>
    <p>Some text in the Modal..</p>
  </div>

</div>

CSS:

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

/* Modal Content/Box */
.modal-content {
    background-color: #fefefe;
    margin: 15% auto; /* 15% from the top and centered */
    padding: 20px;
    border: 1px solid #888;
    width: 80%; /* Could be more or less, depending on screen size */
}

/* The Close Button */
.close {
    color: #aaa;
    float: right;
    font-size: 28px;
    font-weight: bold;
}

.close:hover,
.close:focus {
    color: black;
    text-decoration: none;
    cursor: pointer;
}

JS:

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

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

// 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";
    }
}
