  • Best way to manage the persistence of a form state, to and from a database

    - by Laurent.B
    In a JSP/Servlet webapp, I have to implement a functionality that allows a user to save or restore a form state, that latter containing for instance some search criteria. In other words, the user must be able to save or restore field values of a form, at any time. On the same page that contains that form, there's also another little form that allows him to name his form state before saving it. Then, later he'll be able to recall that state, via a combobox, and refill dynamically the form with the state he selected. I know how to implement that by hand but I would prefer not to reinvent the wheel then I'd like to know if there are some frameworks managing that kind of functionality ? A mix between JSP taglib, filter class, jQuery or other JavaScript frameworks... My research has not give anything yet. Thank you in advance.

  • Codeigniter: How to handle direct link to controller/function/param?

    - by rebjr
    I have a simple controller function which deletes a DB entry (it uses a model function to do so). I have a link to this in one of my views (e.g. http://www.example.com/item/delete/3) and I’m using jQuery to display a confirm dialog to make sure the user really wants to delete it. All fine. However if you just enter that URL in your browser the item is deleted without warning. Is there a way to handle this either in the way I code the controller function or in the model?

  • How to include file from seperate remote folder in Netbeans (PHP Development)

    - by webworm
    I have a PHP project setup in Netbeans (v6.8) where all the PHP files are on a remote server and in a single directory. Whenever I save files locally they are updated on the remote server via SFTP. I now need to edit a remote JavaScript file to add some jQuery logic but the file is located within a different directory on the webserver. How to I add this JavaScript file such that when it is saved or updated it is transferred to it's own location on the server? When I attempt to create the file locally within NetBeans it saves to the same directory as my PHP files. I would like to be able to continue using NetBeans rather than doing this all manually using an SFTP client and a text editor. Thanks in advance.

  • Dropdown menu getting hidden by images

    - by Bob
    I have a set of dropdown menus across the top of a web page. Below is text and some images. When I hover over the top of each menu the menu then expands below as expected but while it overlaps any text on the page it is hidden behind any images. I set the z-index to 9999 and the position is set to absolute. I found if I lower the opacity of the images to say 0.6 then the menu will overlap it. So one solution would be to detect when the menu is being hovered over and then in JavaScript or JQuery temporarily reduce the opacity of the rest of the page until the cursor moves off the menu. If so I'm not sure how to do that but is that the best approach?

  • how to sort an existing table in greasemonkey ?

    - by user570512
    i'm writing a greasemonkey user.js for a page with a table in it. (table is 100 rows by 18 columns.) now what i want to do is to make it sortable on column. and also have it run in both chrome and firefox. all searches for answers sofar resulted in suggestions to use jquery/dojo or something alike. can i be done without any external code? after all it's just a matter of replacing the row's in a different order, right? or is that a silly thing to say? the thing is that i'm already using dojo for some query needs but since i want it to run in both firefox and chrome, i just copy paste the whole dojo thing in my script.. also, most of the solutions i found sofar seem to be more for use when building a table. not for altering an existing one. any help is appreciated.

  • Update a collection_select with user made field

    - by Flexo
    I have a collection_select that i want user to add custom fields to. I have a jQuery script that detects if the row "Custom" is chosen and adds a textfield to the page so the user can enter a custom name. How can i store that custom made name in the db and update the collection_select? <%= f.collection_select :kind_id, Kind.find(:all, :order => "created_at DESC"), :id, :name, {:prompt => "Select a Type" }, {:id => "selector", :onchange => "type_change(this)"} %>

  • Comparing large strings in JavaScript with a hash

    - by user4815162342
    I have a form with a textarea that can contain large amounts of content (say, articles for a blog) edited using one of a number of third party rich text editors. I'm trying to implement something like an autosave feature, which should submit the content through ajax if it's changed. However, I have to work around the fact that some of the editors I have as options don't support an "isdirty" flag, or an "onchange" event which I can use to see if the content has changed since the last save. So, as a workaround, what I'd like to do is keep a copy of the content in a variable (let's call it lastSaveContent), as of the last save, and compare it with the current text when the "autosave" function fires (on a timer) to see if it's different. However, I'm worried about how much memory that could take up with very large documents. Would it be more efficient to store some sort of hash in the lastSaveContent variable, instead of the entire string, and then compare the hash values? If so, can you recommend a good javascript library/jquery plugin that implements an appropriate hash for this requirement?

  • Can I dynamically adjust the height of a css set div border?

    - by Jeff
    Ok so I have a div that contains a few forms that have dynamically generated content. There are categories, that if you click on, slide/toggle down to reveal that categories sub-contents, or projects. Right now, I have it setup so that if the height of the div expands to exceed a set amount, a scroll bar shows up at the side, and the user can scroll down and see the content. NOW I am being asked to get rid of the scroll bar, and just have the div's border (which is just 1px set in the css) height adjust dynamically with the height of the div's content...can I even do that? Is there some sort of jquery animation that would allow that? A point in the right direction would be greatly appreciated!! Thanks

  • clrear coockies and cache from site

    - by salvadore
    Every time i updat my website system UI\Jquery. Users complain that things are not working for them and that they have bugs. Users are internet\computer dummies so they dont know how to clear the coockies or the cache of the browser, so i need to connect to each one of their computers and do it by myself. I spend lots off hours doing it and they always complain. Some of the useres use Chrome, some Firefox. Googled and found no solution for this, Is there any client code operation that will command the browser to clrear its cache or even pop up browser window wich will ask user to confirm the clear?

  • How to have a javascript callback executed after an update panel postback?

    - by TNunes
    I'm using a jQuery tip plugin to show help tips when the user hovers certain elements of the page. I need to register the plugin events after the page is loaded using css selectors. The problem is I'm using an ASP.NET Update Panel and after the first postback, the tips stop working because the update panel replaces the page content but doesn't rebind the javascript events. I need a way to execute a javascript callback after the Update Panel refreshes its content, so I can rebind the javascript events to have the tips working again. Is there any way to do this?

  • Submit form without page reloading

    - by Camran
    I have a classifieds website, and on the page where ads are showed, I am creating a "Send a tip to a friend" form... So anybody who wants can send a tip of the ad to some friends email-adress. I am guessing the form must be submitted to a php page right? <form name='tip' method='post' action='tip.php'> Tip somebody: <input name="tip_email" type="text" size="30" onfocus="tip_div(1);" onblur="tip_div(2);"/> <input type="submit" value="Skicka Tips"/> <input type="hidden" name="ad_id" /> </form> When submitting the form, the page gets reloaded... I don't want that... Is there any way to make it not reload and still send the mail? Preferrably without ajax or jquery... Thanks

  • Is it possible to turn a normal date into an ISO 8601 time format?

    - by Nathan
    I am trying to turn this type of format of the date: Thursday, November 10th, 2011 at 10:37 PM Into an ISO 8601 format (with PHP). How can I do this? I've tried: date("c", $row2['time']) Obviously, that's not correct, because the timeago jQuery plugin is saying "41 years ago", and that is definitely not 41 years ago. Is it not possible to turn that kind of date into the ISO 8601 format? I've tried searching for this and I haven't found any solutions on how to turn this format into ISO 8601.

  • Vew not updating after scope update

    - by bsparacino
    Here is a very simple example of what I am trying to do Athlete.save(athlete,function(result) { $scope.athlete = result.athlete; }); The issue is that the $scope.athlete variable does not update in my view. In order to get it to update I have to do this Athlete.save(athlete,function(result) { $scope.athlete.fname = result.athlete.fname; $scope.athlete.lname= result.athlete.lname; $scope.athlete.gender= result.athlete.gender; .... }); This gets annoying very quickly. With the first block of code it's as if angular does not know that my $scope.athlete variable has been updated. This function is triggered from an ng-click, not some jquery call, I am doing it the angular way as far as I know. here is a simpler case I made: http://plnkr.co/edit/lMCPbzqDOoa5K4GXGhCp

    - by Smickie
    Hi, I'm using prototype and setStyle in IE6 is just messing everything up. It's throwing a big error. I've Googled it but cant find a solution. I've identified the line in prototype with the IE script debugger, it's the final else block: setStyle: function(element, styles) { element = $(element); var elementStyle = element.style, match; if (Object.isString(styles)) { element.style.cssText += ';' + styles; return styles.include('opacity') ? element.setOpacity(styles.match(/opacity:\s*(\d?\.?\d*)/)[1]) : element; } for (var property in styles) if (property == 'opacity') element.setOpacity(styles[property]); else elementStyle[(property == 'float' || property == 'cssFloat') ? (Object.isUndefined(elementStyle.styleFloat) ? 'cssFloat' : 'styleFloat') : property] = styles[property]; return element; }, Anyone had this problem? P.S. normally I would use jQuery however this is someone else code I've had to update.

    - by user1092042
    I have searched high and low for this but whatever i do this simply does not seem to work. I have a google chrome extension which send an XHR request using a background.js file. Now my requirement is that i need to show a small loading icon while the xhr request is proceeding. Are there any tutorials out there which explains how to do this. I have tried an iframe but it looks ugly when it expands as the entire popup.html expands. Is jquery my only option here because that would mean adding a lot of size to my current project just for a simple animation.

I have developed few apps (a desktop app in Java and a mobile app with AngularJS and PhoneGap) I am looking at applying for a part-time programming job to develop myself. Are there part time jobs available for someone like me and are my skill set enough to get me a job? I understand this topic may not be ideal here but this is the only place I know can provide me answers. Thank you!

  • Play Framework Form "fold" method naming rationale

    - by oym
    Play Framework's (2.x) Form class has a method called fold who's usage is indicated as: anyForm.bindFromRequest().fold( f => redisplayForm(f), t => handleValidFormSubmission(t) ) Essentially, the first function parameter is what gets executed on binding failure, and the 2nd on binding success. To me it seems similar to the 'success' and 'error' callbacks of jquery's ajax function. My question is why did the Play developers call the method "fold"? As a disclaimer I am new to Scala, but I am failing to see the connection between this and the functional Scala fold operation. The only similarity is that it is a higher order function; but I don't see any combining that is taking place, nor does it delegate internally in its implementation to any of the Scala fold functions.

  • Rails: How to preload a message to user

    - by Michael
    I have a Rails based prelaunch site that has some rotating background images (which are important for selling the idea of the site) that are taking too long to load, such that the users are leaving the site before they load. The only thing they're seeing is the email submission box. What's a good way to show a message to the users that the site will take some time to load but then have that message disappear after a reasonable period of time. I'm guessing a jQuery fadeOut() with a timer, but I'm not sure how long to set the timer for, because I'm not sure at what time it would start counting. Any suggestions?

  • quickflip + slideshow animation

    - by user288231
    I have been trying to integrate quickflip and a slideshow animation. So everytime when the user hovers over the image, it would pause the animation and "flip to the other side". When the user hovers out, it would then replace its normal state. The problem is here is I do not know how to handle the quickflip code (http://jonraasch.com/blog/quickflip-2-jquery-plugin). I have looked at the sample code and tried to replace it, but at the end the animations would get messed up... Javascript: var interval = setInterval( "slideSwitch()", 3000 ); $('.quickFlip').quickFlip(); $('#slideshow').hover(function () { clearInterval(interval); }, function () { interval = setInterval("slideSwitch()", 3000); });
