  • displayed value - in-place-editor

    - by Ben
    So I put in in-place editing for one of my models. One of the attributes is PRICE. I used the to_currency method to format the value before it is displayed. The problem I'm having is that with the in-place editor, I just can't figure out how to set a custom display value. I'm trying to get the price to display as $20.00 until it is clicked, but the in place editor displays 20.0..

  • Expanding videoplayer like CNN-website, prerably jQuery-based

    - by Nils
    I'm wondering if anyone knows of a script/plugin, jquery-based or otherwise, which could be used to achive the effect that can be found on CNN.com. I'm talking about the videos that are representet by a small thumbnail, that when clicked expands in to the text and plays. I'm by no means a JS-guru, and me and flash isn't the bestest of friends, but I'm not completly cluess. Essentially, what im looking for is a way to click a thumbnail, expand a swf, and stop it if i contract it again. something like that. ANY ideas, tips or insights are welcome!

  • Pull DIV from separate page and update DIV in current page

    - by brhea
    Hi everyone, I've got a simple one but haven't been able to find an example of a solution that fits exactly what I'm asking. Sorry in advance if this is a repeat. From my navigation menu, I want each link to reference a specific DIV in a separate page and then pull that DIV and replace the content in the current page. <ul> <li><a href="#">About</a></li> <li><a href="#">Contact</a></li> ..and so on </ul> Elsewhere in the page: <div id="displayContent">Content refreshes onClick. Previous content fades out, fresh content fades in.</div> Separate page (content.php): <div id="about">About content</div> <div id="contact">Contact content</div>

  • How does dzone.com maintain state of the div?

    - by CShipley
    When you scroll down to the bottom of http://www.dzone.com/links/ it automatically loads more links. However, when you navigate away, then hit the back button, the contents of the modified div stay there. How do they get the browser to go back to a dynamically generated div?

  • Form submission and hyperlinks using GET and POST

    - by Jon
    I have a search resource, the user can perform searches by filling out a form and submitting it, the create action is called, the Search is saved, the show action is called, and the results are displayed. This all happens with the default POST, and all works fine. The user may want to save his search in the saved_search table (i don't use the Search table for this purpose as this table stores all searches for the purpose of compiling statistics, and gets cleared on a regular basis). Once the Search is saved, it can be re-run by clicking a hyperlink, this is where i start to get problems. I see no way of getting my hyperlink to run the create action of Search, with a POST request, and the necessary data. I then decided to try to get both form submission and the hyperlink to perform a search using a GET request, i was unable to get form_for to run my Search create action using a GET request, it always seems to get routed to my index action. Can someone suggest a good restful solution to this problem please. Many thanks

  • prevent form from automatically re-submitting on page load

    - by user323774
    I am using jQuery to point a form's target to an iframe on .submit(). This is to upload a file. It works fine, but when the page reloads, and the iframe is appended to the DOM, the iframe automatically resubmits the form, causing the same file to be sent to the server on each page load. If I do not include the iframe in the HTML markup, or do not append it to the DOM, this doesn't happen, but of course, I need the iFrame. So my question is, how can i prevent this? :) Andrew

  • Creating a form on non-gui thread

    - by luntain
    You can't access gui controls from a thread they were not created on, at least so says the message of an exception that is sometimes raised when you do it. Recently I was puzzled by seeing that forms created on background threads work just fine. My mental model was that all actions initiated by UI input is handled on the GUI thread. Clicking on a button on such a form should raise the dreaded exception (the form and all its controls were created on a background thread not the gui thread), but it doesn't. Something is wrong with my map. (*) well to be honest I have seen one problem where opening the standard open file dialog was blocking everything

  • Progressive enhancement of anchor tags to avoid onclick="return false;"

    - by Chris Beck
    Unobtrusive JS suggests that we don't have any onclick attributes in our HTML templates. <a href="/controller/foo/1">View Foo 1</a> A most basic progressive enhancement is to convert an that anchor tag to use XHR to retrieve a DOM fragment. So, I write JS to add an event listener for a."click" then make an XHR to a.href. Alas, the browser still wants to navigate to "/controller/foo". So, I write JS to dynamically inject a.onclick = "return false;". Still unobtrusive (I guess), but now I'm paying the the cost of an extra event handler. To avoid the cost of 2 event listeners, I could shove my function call into the onclick attribute <a href="/controller/foo/1" onclick="myXHRFcn(); return false;"> But that's grodo for all sorts of reasons. To make it more interesting, I might have 100 anchor tags that I want to enhance. A better pattern is a single listener on a parent node that relies on event bubbling. That's cool, but how do I short circuit the browser from navigating to the URL without this on every anchor node? onclick="return false;" Manipulating the href is not an option. It must stay intact so the context menu options to copy or open in new page work as expected.

  • Display error when entire form is blank in CodeIgniter

    - by Joe
    I'm trying to create a fairly simple form that has a few checkboxes and input fields and a textarea. Nothing is required by itself; however, if 'A' checkbox is checked, then 'A' input field is required (and so on for the couple other checkboxes I have). I have the above functionality in place, but I'm having a tough time figuring out how to have an error returned if the form is submitted blank (since nothing is required by default). Does anyone know of an easy-ish solution for this? It seems like it should be so simple... Thanks

  • How to use $.get data to replace certain elements in a webpage?

    - by Jack Ha
    I'm using jQuery 1.4.2 to navigate smoothly between similar webpages (in ff3). When clicking on a link, a javascript script should load the new html, filter out the right elements and replace them on the current page. It looks like the $(htmlcode) does not do the thing I expected. The actions below work when loading the page directly, but when using the $.get I have the following problems: the find function seems only to look inside a div element called id="page", which is inside the body element one of the elements has <script>...</script>, but the <script>...</script> is not present in the DOM of $(htmlcode). Anybody knows how to solve this? $.get( url, function(responseText, textStatus, xmlHttpRequest) { alert($(responseText).find("#header")); // works, #header is inside div#page alert($(responseText).find("#header").html()); // displays content, but WITHOUT the <script>...</script> alert($(responseText).find("title")); // does not work, title is outside div#page } );

  • Parsing html output and executing javascript

    - by user1841964
    I have this function: function parseScript(_source) { var source = _source; var scripts = new Array(); while(source.indexOf("<script") > -1 || source.indexOf("</script") > -1) { var s = source.indexOf("<script"); var s_e = source.indexOf(">", s); var e = source.indexOf("</script", s); var e_e = source.indexOf(">", e); scripts.push(source.substring(s_e+1, e)); source = source.substring(0, s) + source.substring(e_e+1); } for(var i=0; i<scripts.length; i++) { try { eval(scripts[i]); } catch(ex) { } } return source; } It parses and execute Javascript wonderfully except the when in <script type='text/javascript' src='scripts/gen_validatorv31.js'></script> the src file never gets executed.

  • Grails: can remoteField update multiple fields?

    - by Michael Bavin
    Hi, Assume i have a book entity with an isbn field. When entered a isbn number, i want 2 fields to be updated: title and author. My controller looks like this: def ajaxGetBook = { def book = Book.findByIsbn(params.isbn) if(book==null) book = new Book() render book as JSON } So my call works, and i get a full JSON Book. Now i would like to update 2 texfields by the update attribute <g:remoteField action="ajaxGetBook" update="title" name="isbn" value="${bookInstance?.book?.isbn}" paramName="isbn"/> Now the title field gets updated with the full book object, so that doesn't work. Is it possible to update field title with only the JSON book.title? Is it possible to update more fields at once? I could render book.title as JSON but that works for only one field. Thank you
