  • Validation of dependent properties in a "live edit" WPF app

    - by Ryan Cromwell
    I'm working on an app which supports live editing. That is you update properties in one area and their impact is seen in another with hitting "apply". Happens to be a charting app. One such edit "group" allows specifying a range. A triple range in fact: High, Target and Low. Our validation is such that High must be greater than target, target must be greater than Low (rocket science). Our dilemma is that the visual experience is a bit jarring when someone wants to go from say 30,20,10 to 15,10,5. I'm curious if anyone has implemented a mechanism for this scenario that might fit well in our situation such that we don't "yell" at the user as they change the range values.

  • jquery: adding class on to list-items only on mouseover-remove on mouse-out?

    - by user239831
    hey guys, what's the best way to do that: i have a list <ul> <li>hello</li> <li>good bye</li> <li>arrivederci</li> <li class="selected">dude</li> <li>whatever</li> </ul> Initially one item already has a class of .selected applied. When i hover over one of the list-items i want this one to have the .selected class. So every item should only have the class applied when im over, as soon as i leave the item the class get's removed and the next one has the class.

  • jQuery Looking for a function to equalize heights of divs based on tallest image in a table.

    - by Jamie
    I am doing a site that will have a table with a bunch of images in them. They are user added images so I have no control over aspect ratio, what I do have control over is I can the force a max height/width and the image will not exceed this in either direction, but the height can (and will) fluctuate. <table class="pl_upload"> <tr class="row1"> <td class="col1"> <div> <div class="img-container"> <a href="#"><img src="img.jpg" width="182" alt="X" /></a> </div> </div> </td> ....... What I need ideally is to get the height of the tallest image and then make the all of the children divs the same height based on the height of the tallest one. I hope that makes sense, been a long day. I made a jsfiddle page for it here: http://jsfiddle.net/Evolution/27EJB/

  • How can i fix this jquery script for submenu?

    - by Giulio Bambini
    This is the code and this is the result: www.studionews24.com you can see test the menu by clicking inside. $(document).ready(function () { var $links = $('#menu-menu-1 .menu-item a').click(function () { var submenu = $(this).next(); $subs.not(submenu).hide() submenu.toggle(500); $("#menu-2").slideToggle(300); }); var $subs = $links.next(); }); The problem is that if I click on the menu it appears the submenu, but if I don't close the submenu that I have open and I open another voice in the menu it doesn't work properly. If I click another .menu-item a when #menu-2 is open what happens? The script close and open another submenu correctly but my #menu-2 close only close. And then if I close .menu-item a so... #menu-2 open. How can I do to fix?

  • How can I call `update_attribute` for a list item in rails then actually update the html using jquery?

    - by Patrick Connor
    I want my users to be able to mark one or more items from an index view as "Active" or "Inactive" using a link. The text for the link should be state aware - so it might default to "Mark as Active" if the corresponding attribute was false or null, and "Mark as Inactive" if true. Once the user clicks the link and the attribute is updated in the controller, the link-text should update based on the new state. I am WAY off here, but this is a small sample of the code I have been trying... CONTROLLER ... respond_to :html, :js ... def update @item = Item.find(params[:id]) if @item.update_attributes(params[:item]) #Not sure of how to respond to .js here end end ... update.js.erb #how do I identify which element to update? $('#item[13456]').html("State aware text for link_to") VIEW - for item in @items = item.name = link_to "Mark as Active", item_path(item), :method => :put, :remote => true. :id => "item[#{item.id}]" I am happy to read any APIs, blogs, tutorials, etc. I just can't seem to get my hands/mind around this task. Any help or guidance is greatly appreciated!

  • jquery element not defined, but it used to skip it...

    - by pfunc
    I recently transferred a site to a new host. Reloaded everything, and the javascript that worked fine before is breaking at an element it can't find. $('#emailForm') is not defined. Now, the #emailform isn't on the page, but it wasn't before either, and JS used to skip this and it would just work. Not sure why this is happening. Any clues?

  • Using jQuery, how to modify text outside of tags?

    - by Jacob
    Given a string of text that is both adjacent to a span and inside of a div, what are some methods to modify just that text, leaving the surrounding HTML intact? For example: <div id="my-div">modify this text<span id="my-span"></span></div> I have tried things like $('#my-div').html(function(i, elem){blah;}); but this seems to cause the span to be deleted and a new span to be added, because some styling is lost. I realize that it would be best to wrap the text string in its own HTML tags before applying client-side code, but that is out of my control.

  • jQuery make child div visible on hover (on effective li element only, not parent!)

    - by Dennis
    I've already tried all of the existing posts related to this, but they doesn't work as I want it... The HTML: <ol class="sortable"> <li> <div> <a href="#">Start Page</a> <div class="li_options"> <a href="#"><img src="img/icons/small_add.png" /></a> <a href="#" onClick="[..]"><img src="img/icons/small_remove.png" /></a> </div> <div class="clear"></div> </div> <ol> <li> <div> <a href="#">Sub Seite</a> <div class="li_options"> <a href="#"><img src="img/icons/small_add.png" /></a> <a href="#" onClick="[..]"><img src="img/icons/small_remove.png" /></a> </div> <div class="clear"></div> </div> <ol> <li> <div> <a href="#">Sub Sub Seite</a> <div class="li_options"> <a href="#"><img src="img/icons/small_add.png" /></a> <a href="#" onClick="[..]"><img src="img/icons/small_remove.png" /></a> </div> <div class="clear"></div> </div> </li> </ol> </li> </ol> </li> <div class="clear"></div> This should look like this: Start Page Sub Page Sub Page I want the div.li_options which is set for every li element to be shown only on hovering element. I know, that the parent's li is also being "hovered" on hovering child elements, but I don't those "li_options" to be displayed. The best solution so far: $(document).ready(function() { $('.sortable li').mouseover(function() { $(this).children().children('.li_options').show(); }).mouseout(function() { $(this).children().children('.li_options').hide(); }); }); But with this, parents aren't being excluded... I don't know how to point on them, because there can be endless levels. Do you know how to get this working?

    I have the following rule on my local dev site and it works fine: RewriteCond %{HTTP_HOST} ^localhost$ RewriteRule ^subdomains/example.com(.*) http://www.example.com$1 [R=301,L] However when I change it to: RewriteCond %{HTTP_HOST} ^www.domain.com$ RewriteRule ^subdomains/example.com(.*) http://www.example.com$1 [R=301,L] and upload it to my live site it doesn't work, if i change the rule to: RewriteCond %{HTTP_HOST} ^www.domain.com$ RewriteRule ^subdomains/(.*) http://www.example.com$1 [R=301,L] the rule functions as expected and directs an url beginning with www.domain.com/subdomains/ to www.example.com/. Does anyone know what is going on here? Thanks for you help.

  • How do I change the curosr during a jQuery synchronous browser blocking POST?

    - by Tommy
    $.ajax({ url: "/cgi-bin/stats.exe", method: "post", async: false, data: { refresh: "a41" } }); Using ajax post synchronously - "async: false". While it blocks the browser during the active request, what is the most efficient way to change the cursor to the hourglass or display a wait .gif? Perhaps set the cursor as it enters this function then change it back in the success or complete function? Any advice is appreciated. Thank You.

  • How do I bind the Overlay Tool for new Ajax elements in Jquery?

    - by Hooman Ahmadi
    Hi, I'm using: echo $javascript->link('tools.overlay-1.0.4', false); which is initialized with: $(".overlay_popup").overlay({ expose: '#000000', close: '.close_overlay', finish: { top: 'center', left: 'center', absolute: false } }); I call the overlay popup box like this: echo $html->link( "add part", array('controller'=>'garage_parts', 'action'=>'addfrompartlist', $gcar['GarageCar']['id'], $gcar['GarageCar']['car_id']), array('class'=>'js-ajax overlay_popup', 'id'=>'add_part_overlay', 'rel'=>'.overlay_container') ); This all works fine and dandy, however I have an ajax function that dynamically adds the "add part" hyperlink button shown above and I have no idea how to bind this new button to the overlay. Normally, I would use something like this: $(".overlay_popup").bind("click", function(){... but this didn't work for the overlay. Any ideas on how I can successfully do this?
