How to code a JavaScript modal popup (to replace Ajax)?


I need to replace our Ajax Modal Popup controls with a JavaScript equivalent. We use this as a simple context sensitive help type popup. I did a quick browse but didn't see quite what I was looking for. I just need some text and a simple Close button/link, but I would like the page darkened below the popup, as it does with the Ajax modal control.

Can anyone suggest a nice JavaScript popup/help type solution that you've used?


Solution

  • I can provide you the code. Do your modifications as necessary, OK?

    Page JavaScript:

    function myPop() { 
        this.square = null;
        this.overdiv = null;
    
        this.popOut = function(msgtxt) {
            //filter:alpha(opacity=25);-moz-opacity:.25;opacity:.25;
            this.overdiv = document.createElement("div");
            this.overdiv.className = "overdiv";
    
            this.square = document.createElement("div");
            this.square.className = "square";
            this.square.Code = this;
            var msg = document.createElement("div");
            msg.className = "msg";
            msg.innerHTML = msgtxt;
            this.square.appendChild(msg);
            var closebtn = document.createElement("button");
            closebtn.onclick = function() {
                this.parentNode.Code.popIn();
            }
            closebtn.innerHTML = "Close";
            this.square.appendChild(closebtn);
    
            document.body.appendChild(this.overdiv);
            document.body.appendChild(this.square);
        }
        this.popIn = function() {
            if (this.square != null) {
                document.body.removeChild(this.square);
                this.square = null;
            }
            if (this.overdiv != null) {
            document.body.removeChild(this.overdiv);
            this.overdiv = null;
            }
    
        }
    }
    

    Now the HTML page, using the JavaScript file:

    <html> 
      <head>
        <script type="text/javascript" src="NAME OF THE PAGE!.js"></script>
        <style>
            div.overdiv { filter: alpha(opacity=75);
                          -moz-opacity: .75;
                          opacity: .75;
                          background-color: #c0c0c0;
                          position: absolute;
                          top: 0px;
                          left: 0px;
                          width: 100%; height: 100%; }
    
            div.square { position: absolute;
                         top: 200px;
                         left: 200px;
                         background-color: Menu;
                         border: #f9f9f9;
                         height: 200px;
                         width: 300px; }
            div.square div.msg { color: #3e6bc2;
                                 font-size: 15px;
                                 padding: 15px; }
        </style>
      </head>
      <body>
        <div style="background-color: red; width: 200px; height: 300px;
                    padding: 20px; margin: 20px;"></div>
    
        <script type="text/javascript">
            var pop = new myPop();
            pop.popOut("Jose leal");
        </script>
      </body>
    </html>
    

    Hope that this can help.
