  • Undo implementation - DOM manipulations

    - by sonofdelphi
    Is there a library that can be used for implementing undo/redo functionality for DOM element manipulations in JavaScript? I'm writing an app that moves around DOM elements, enables editing and deletion of those elements. There are event-handlers and other objects associated with each element operated upon. Not sure whether I need to roll my own implementation of the Command pattern for this. Surely, there must be something available? If not, suggestions and pointers would be a great help.

  • show div for a set time, then hide it

    - by Patrick
    Im using jquery for various things on my site, but one thing im not sure how to do, is have it show an element, then wait X seconds, and hide the element. $('#form').ajaxForm(function() { $('#cartcontents').fadeOut("fast").load('cart.php').fadeIn("fast"); }); That's the JavaScript that I'm using now. How could I have it (when the form submits) display the div #notice for 5 seconds, then fadeOut?

  • simple method that checks text is email with regular expression

    - by user223863
    Can't believe how difficult this seems to be all I want to is to validate a user inout using javascript to make sure that it is an email address. But can't get it to work: I am using: //validates a regulaer expression Utilities2.prototype.validateEmail = function(stringToValidateArg) { alert('about to check regexp'); var regExpPattern = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/; alert(regExpPattern.test(stringToValidateArg)); } But this always returns false, any ideas why is it because of the regular expression?

  • Escaping HTML strings with jQuery

    - by Page Brooks
    Does anyone know of an easy way to escape HTML from strings in jQuery? I need to be able to pass an arbitrary string and have it properly escaped for display in an HTML page (preventing JavaScript/HTML injection attacks). I'm sure it's possible to extend jQuery to do this, but I don't know enough about the framework at the moment to accomplish this.

  • How do I make menus like these?

    - by Doug
    So I'm looking at slickdeals.net and amazon.com, and I found something very intriguing. It's basic for most of you guys out there, but it's new to me. For slickdeals.net, when you click login, a login box pops up like so. Also for Amazon.com, when you hover over the left navigational menus, a new menu pops up! I think it's JavaScript, but how does this work? How can I do something like that?

  • How can I implement a 'select all' check-box on my CRM 4 custom form?

    - by Gryphoenix
    I am working on a custom CRM form with numerous checkboxes, organized by sections. I would like to implement a 'select all' feature to the form and am trying to understand how to format the JavaScript. My research thus far has pointed me to the possibility of using a FOR statement to iterate through all of the elements in the section I want to process, setting their values accordingly, but am unsure of which document.getElements ... method to utilize.

    For simplicity sake, lets use the XML example on Econym's site. http://econym.org.uk/gmap/example_map3.htm Once clicked, I would like icon balloon to be displayed in the middle of the map. What might I need to add to Mike's code to get this to work? I apologize for asking a lot.. Thanks in advance. <script type="text/javascript"> //<![CDATA[ if (GBrowserIsCompatible()) { side_bar var side_bar_html = ""; var gmarkers = []; function createMarker(point,name,html) { var marker = new GMarker(point); GEvent.addListener(marker, "click", function() { marker.openInfoWindowHtml(html); }); gmarkers.push(marker); side_bar_html += '<a href="javascript:myclick(' + (gmarkers.length-1) + ')">' + name + '<\/a><br>'; return marker; } function myclick(i) { GEvent.trigger(gmarkers[i], "click"); } var map = new GMap2(document.getElementById("map")); map.addControl(new GLargeMapControl()); map.addControl(new GMapTypeControl()); map.setCenter(new GLatLng( 43.907787,-79.359741), 9); GDownloadUrl("example.xml", function(doc) { var xmlDoc = GXml.parse(doc); var markers = xmlDoc.documentElement.getElementsByTagName("marker"); for (var i = 0; i < markers.length; i++) { // obtain the attribues of each marker var lat = parseFloat(markers[i].getAttribute("lat")); var lng = parseFloat(markers[i].getAttribute("lng")); var point = new GLatLng(lat,lng); var html = markers[i].getAttribute("html"); var label = markers[i].getAttribute("label"); var marker = createMarker(point,label,html); map.addOverlay(marker); } document.getElementById("side_bar").innerHTML = side_bar_html; }); } else { alert("Sorry, the Google Maps API is not compatible with this browser"); } //]]> </script>
