Window.open 作为模态弹出窗口？

Question

I want open window.open as modal popup.

 var features = 'resizable= yes; status= no; scroll= no; help= no; center= yes;
 width=460;height=140;menubar=no;directories=no;location=no;modal=yes';
    window.open(href, 'name', features, false);

I can use Window.ShowModelDialog() , but in my child window I am calling parent javascript method. That is not happening with ShowModelDialog().

 function CallParentScript(weburl) {
       alert(weburl);
       if (weburl != null) {
           var url = weburl;

            window.opener.SelectUserImageCallback(url);
            window.close();
            return false;
       }
   }

If I use window.open() . I can call Parent javascript. But window is not modal.

How to solve this? Can I write something in child popup to always top?

Answer 1

A pop-up is a child of the parent window, but it is not a child of the parent DOCUMENT. It is its own independent browser window and is not contained by the parent.

Use an absolutely-positioned DIV and a translucent overlay instead.

EDIT - example

You need jQuery for this:

<style>
html, body {
    height:100%
}


#overlay { 
    position:absolute;
    z-index:10;
    width:100%;
    height:100%;
    top:0;
    left:0;
    background-color:#f00;
    filter:alpha(opacity=10);
    -moz-opacity:0.1;
    opacity:0.1;
    cursor:pointer;

} 

.dialog {
    position:absolute;
    border:2px solid #3366CC;
    width:250px;
    height:120px;
    background-color:#ffffff;
    z-index:12;
}

</style>
<script type="text/javascript">
$(document).ready(function() { init() })

function init() {
    $('#overlay').click(function() { closeDialog(); })
}

function openDialog(element) {
    //this is the general dialog handler.
    //pass the element name and this will copy
    //the contents of the element to the dialog box

    $('#overlay').css('height', $(document.body).height() + 'px')
    $('#overlay').show()
    $('#dialog').html($(element).html())
    centerMe('#dialog')
    $('#dialog').show();
}

function closeDialog() {
    $('#overlay').hide();
    $('#dialog').hide().html('');
}

function centerMe(element) {
    //pass element name to be centered on screen
    var pWidth = $(window).width();
    var pTop = $(window).scrollTop()
    var eWidth = $(element).width()
    var height = $(element).height()
    $(element).css('top', '130px')
    //$(element).css('top',pTop+100+'px')
    $(element).css('left', parseInt((pWidth / 2) - (eWidth / 2)) + 'px')
}


</script>


<a href="javascript:;//close me" onclick="openDialog($('#content'))">show dialog A</a>

<a href="javascript:;//close me" onclick="openDialog($('#contentB'))">show dialog B</a>

<div id="dialog" class="dialog" style="display:none"></div>
<div id="overlay" style="display:none"></div>
<div id="content" style="display:none">
    Lorem ipsum dolor sit amet, consectetur adipiscing elit. Proin nisl felis, placerat in sollicitudin quis, hendrerit vitae diam. Nunc ornare iaculis urna. 
</div>

<div id="contentB" style="display:none">
    Moooo mooo moo moo moo!!! 
</div>

You can try open a modal dialog with html5 and css3, try this code:

 .windowModal { position: fixed; font-family: Arial, Helvetica, sans-serif; top: 0; right: 0; bottom: 0; left: 0; background: rgba(0,0,0,0.8); z-index: 99999; opacity:0; -webkit-transition: opacity 400ms ease-in; -moz-transition: opacity 400ms ease-in; transition: opacity 400ms ease-in; pointer-events: none; } .windowModal:target { opacity:1; pointer-events: auto; } .windowModal > div { width: 400px; position: relative; margin: 10% auto; padding: 5px 20px 13px 20px; border-radius: 10px; background: #fff; background: -moz-linear-gradient(#fff, #999); background: -webkit-linear-gradient(#fff, #999); background: -o-linear-gradient(#fff, #999); } .close { background: #606061; color: #FFFFFF; line-height: 25px; position: absolute; right: -12px; text-align: center; top: -10px; width: 24px; text-decoration: none; font-weight: bold; -webkit-border-radius: 12px; -moz-border-radius: 12px; border-radius: 12px; -moz-box-shadow: 1px 1px 3px #000; -webkit-box-shadow: 1px 1px 3px #000; box-shadow: 1px 1px 3px #000; } .close:hover { background: #00d9ff; }

 <a href="#divModal">Open Modal Window</a> <div id="divModal" class="windowModal"> <div> <a href="#close" title="Close" class="close">X</a> <h2>Modal Dialog</h2> <p>This example shows a modal window without using javascript only using html5 and css3, I try it it¡</p> <p>Using javascript, with new versions of html5 and css3 is not necessary can do whatever we want without using js libraries.</p> </div> </div>

Answer 3

That solution will open up a new browser window without the normal features such as address bar and similar.

To implement a modal popup, I suggest you to take a look at jQuery and SimpleModal , which is really slick.

(Here are some simple demos using SimpleModal: http://www.ericmmartin.com/projects/simplemodal-demos/ )

Answer 4

I agree with both previous answers. Basically, you want to use what is known as a "lightbox" - http://en.wikipedia.org/wiki/Lightbox_(JavaScript)

It is essentially a div than is created within the DOM of your current window/tab. In addition to the div that contains your dialog, a transparent overlay blocks the user from engaging all underlying elements. This can effectively create a modal dialog (ie user MUST make some kind of decision before moving on).
