carcoal Posted October 11, 2016 Share Posted October 11, 2016 Hello, I am new to web design and I have to do a web page for class. I have hit a roadblock. I am making a list of 25 films and with each film listed, I wanted a modal box to pop up and give more information on the film. I'm using one of the w3schools tutorial: http://www.w3schools.com/howto/howto_css_modals.asp I am pretty much following this code exactly, save for a font change and background color change. My question is how to make multiple modal boxes for the page? I am thinking maybe the ID needs changing, but I am not sure. I have played around with the code but can't get more than one to pop up. I'm not exactly sure what all needs to change in order for more than one to pop up. Any help would be greatly appreciated!! Link to comment Share on other sites More sharing options...
dsonesuk Posted October 11, 2016 Share Posted October 11, 2016 They are several ways to do this depending on your needs. 1) Have multiple modals containing content, which allow you to open multiple modals.. 2) Have the modal content stored hidden on page, with single Modal, when activated the hidden content is gathered and inserted into modal, one modal open at one time only 3) Have the modal content retrieved from database using AJAX, with single Modal, when activated the content is gathered from database and inserted into modal, one modal open at one time only 4) As (3) but with possible multiple modals open at one time 5) As (4) but with possible multiple modals open at one time ALL multiple modal pop-ups, involve rewriting code, where unique singular ID is used, to change to class instead, and code to reflect this change.

carcoal Posted October 11, 2016 Author Share Posted October 11, 2016 Thank you for the reply! I have a few questions: With the HTML, to make different classes for the multiple modals, would I have to make it: <div class="myModal1" class="modal"> For the first and then <div class="myModal2" class="modal"> for the second one, something like that? Or could the <div class="myModal" class="modal"> suffice for all 25? and then for the JavaScript, instead of making them ids, replace them with classes like this, right? // Get the modal var modal = document.getElementByclass('myModal1'); [and then myModal2, myModal3...] Lastly, I was wondering for each of the 25 modals, when you change them to class, do I add CSS for each of the 25? I have been playing with making them classes but now when I open my page, the modal boxes are already up and I can't close them. My plan for the modal box was that when the image was clicked on, a box would pop up. Then the user can then exit out the modal. And then they click on the next image and then the second modal comes up. Thank you again for any assistance! Link to comment Share on other sites More sharing options...
dsonesuk Posted October 11, 2016 Share Posted October 11, 2016 Firstly YOU can't have multiple class attributes. <div class="myModal modal"> WILL suffice for all 25? With multiple modal classes instead of ids you can indeed use modal = document.getElementByclass('myModal'); The styling of modals is done to class names, not 'ID', you can keep original current class names so current styling remains, and add as addition another class name (as shown 2nd line), this addition will be used as a reference to opening closing multiple modals. If you wish to style, add click event, you can use modal.length to get total number of these modal classes, and then use for loop to apply any styling or js event.

dsonesuk Posted October 12, 2016 Share Posted October 12, 2016 As long as button/image sequence matches modal sequence, a custom data- index identifier is added to each button/image, Modal and closing element to identify which modal to act on. Also if you still want to use original modal code, I modified it slightly so there won't be a conflict between both. <!DOCTYPE html> <html> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <meta name="viewport" id="viewport" content="target-densitydpi=high-dpi,initial-scale=1.0,user-scalable=no" /> <title>Document Title</title> <link rel="stylesheet" href="http://www.w3schools.com/lib/w3.css"> <style> /* The Modal (background) */ .modal { display: none; /* Hidden by default */ position: fixed; /* Stay in place */ z-index: 1; /* Sit on top */ padding-top: 100px; /* Location of the box */ 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 */ .modal-content { background-color: #fefefe; margin: auto; padding: 20px; border: 1px solid #888; width: 80%; } /* The Close Button */ .close { color: #aaaaaa; float: right; font-size: 28px; font-weight: bold; } .close:hover, .close:focus { color: #000; text-decoration: none; cursor: pointer; } </style> </head> <body> <h2>Modal Example</h2> <!-- Trigger/Open The Modal --> <button class="myBtn_multi">Open Modal</button> <button class="myBtn_multi">Open Modal2</button> <!-- The Modal --> <div class="modal modal_multi"> <!-- Modal content --> <div class="modal-content"> <span class="close close_multi">×</span> <p>Some text in the Modal..</p> </div> </div> <!-- The Modal --> <div class="modal modal_multi"> <!-- Modal content --> <div class="modal-content"> <span class="close close_multi">×</span> <p>Some text in the Modal..2</p> </div> </div> <!-- Trigger/Open The Modal --> <button id="myBtn">Open Modal --- OLD</button> <!-- The Modal --> <div id="myModal" class="modal"> <!-- Modal content --> <div class="modal-content"> <span class="close">x</span> <p>Some text in the Modal.
