  • Use jQuery on a variable instead on the DOM ? [solved]

    - by Stef
    In jQuery you can do : $("a[href$='.img']").each(function(index) { alert($(this).attr('href')); } I want to write a jQuery function which crawls x-levels from a website and collects all hrefs to gif images. So when I use the the get function to retrieve another page, $.get(href, function(data) { }); I want to be able to do something like data.$("a[href$='.img']").each(function(index) { }); Is this possible ? ...UPDATE... Thanks to the answers, I was able to fix this problem. function FetchPage(href) { $.ajax({ url: href, async: false, cache: false, success: function(html){ $("#__tmp__").append("<page><name>" + href + "</name><content>" + html + "</content></page>"); } }); } See this zip file for an example how to use it.

  • Regex: How to leave out webding font characters?

    - by DS
    Hi, I've a free text field on my form where the users can type in anything. Some users are pasting text into this field from Word documents with some weird characters that I don't want to go in my DB. (e.g. webding font characters) I'm trying to get a regular expression that would give me only the alphanum and the punctuation characters. But when I try the following, the output is still all the characters. How can I leave them out? <html><body><script type="text/javascript">var str="???????";document.write(str.replace(/[^a-zA-Z 0-9 [:punct]]+/g, " "));</script></body></html>

  • Jquery How to use history plugin?

    - by Martijn
    In my web application I am using ajax and now I'd like the back and forward browser buttons to work. So I went looking for a jquery history plugin and found this one: http://stilbuero.de/jquery/history In my code I use a function to load a page: function loadDocument(id, doc) { $("#DocumentContent").show(); // Clear dynamic menu items $("#DynamicMenuContent").html(""); $("#PageContent").html(""); // Load document in frame $("#iframeDocument").attr("src", 'ViewDoc.aspx?id=' + id + '&doc=' + doc + ''); // Load menu items $("#DynamicMenuContent").load("ShowButtons.aspx"); } As you can see I want my pages to load within an Iframe. Can someone tell me how I can use a history plugin so that the brwoser buttons will work? I don't really care which plugin it is, as long as the browser buttons work. I prefer an easy to use plugin.

  • Setting cookie in LiftFilter

    - by Gero
    Hi, How do I set a cookie in a LiftFilter.doFilter method? I tried to set the cookie as follows (stripped some code): class AuthenticationFilter extends LiftFilter { override def doFilter(request: ServletRequest, response: ServletResponse , chain: FilterChain) { val cookie = new HTTPCookie("SomeCookie", Full("" + System.nanoTime), Empty, Full("/authentication"), Full(60 * 60 * 24 * 14), Empty, Empty) cookie.setPath("/somePath") S.addCookie(cookie) val httpResp = response.asInstanceOf[HttpServletResponse] httpResp.sendRedirect("/some/page.html") } } However, when I check the browsers cookie, no cookie is set (apart from JSESSIONID), and I know the doFilter method is being executed because of logging messages and the fact that the browser is redirected to /some/page.html. I'm using Scala 2.8, Lift 2.1-SNAPSHOT and the app is running is GAE (1.3.6, only tested on dev_appserver so far). Any ideas? Thanks, Gero

  • How do I pass a javascript parameter to an asp.net MVCmodel from within a View?

    - by Josh
    Hi everyone! I am having an issue trying to access a list property on a model from within a javascript. My basic situation is this: I have an ArticleController and an ArticleViewModel. An Article has a number of properties, one of which is Text, which is just a string that contains the contents of the article. The ArticleViewModel contains a Pages property, which is just a List of Strings. When the ArticleViewModel constructor is called, I populate the Pages list by dividing up the article text based on some delimeters. I have a View which inherits the ArticleViewModel type. What I want to do is only display one page at a time, and then when the user clicks a page number (from a list at the bottom of the article), I want to use javascript to load that page into the #dynamicContent div. The problem: I can't seem to pass a parameter to the Model.Pages property from within javascript... Is this possible? I get an error stating, "Expression Expected" when I try what I have below. I don't want to have to worry about AJAX calls or anything like that since I already have the entire article... I just need a way to access each individual page from within the javascript function. Alternatively, if there is a better solution for "paginating" an article so that I can load each articlePage without having to refresh the entire html page, I would certainly be open to that as well. Any help would be much appreciated!! Thanks for your time! ArticleView Code: Script at the top of the view: function loadPage(pageNumber) { try { alert(pageNumber); $('#dynamicContent').html('<%=Model.Pages(' + pageNumber + ') %>'); } catch (e) { alert('in here'); alert(e.description); } } HTML for view: [...] <div id="articleBody"> <div id="dynamicContent"> <%=Model.Pages(0)%> </div> </div> [...] Page Links at bottom of page: [...] <div> <ul style="display:block"> <li style="display:inline"> <a href="#articleTitle" onclick="loadPage(0)"> 1 </a> </li> <li style="display:inline"> <a href="#articleTitle" onclick="loadPage(1)"> 2 </a> </li> </ul> </div>

  • Dynamic menu items (change text on click)

    - by Mathijs Delva
    Hello, i need some help with a menu. See the following menu: menu The code for this menu: <div id="menu"> <ul> <li class="home"><a href="#home" class="panel">home / <span class="go">you are here</span></a></li> <li class="about"><a href="#about" class="panel">about / <span class="go">go here</span></a></li> <li class="cases"><a href="#cases" class="panel">cases / <span class="go">go there</span></a></li> <li class="photos"><a href="#photos" class="panel">photos / <span class="go">maybe here</span></a></li> <li class="contact"><a href="#contact" class="panel">contact / <span class="go">or even here<span></span></a></li> </ul> </div> What i want to do: onclick a menu item: 1. change the red text to yellow 'you are here' 2. change the previous menu item back to its original state (eg red and "go here"). The 4 values "go here", "go there", "maybe here", "or even here" are the 4 values that should be assigned to the other menu items (like the example). This is the code i already have: $('#menu ul li.home').addClass('active') $('#menu ul li.active a .go').html("you are here"); $("#menu ul li").click(function () { $('#menu ul li.active').removeClass('active'); $(this).addClass('active'); $('#menu ul li.active a .go').html("you are here"); }); var arr = [ "go here", "go there", "maybe here", "or even here" ]; var obj = { item1: "go here", item2: "go there" ,item3: "maybe here", item4: "or even here"}; $('#menu ul li').click(function () { var str = $('#menu ul li.active a .go').text(); $('#menu ul li.active a .go').html(str); }); As you see, it's incomplete. I don't how to get the values from the array and assign them too a menu item. The replace text works, but not the change-back-to-original-state. Also, right now, for some reason i can't click ONTO the list item itself in order to activate the jquery code. I need to click just a few pixels under it. But i guess that's a css issue. If anyone can help, i'd be super thankful! Regards, Mathijs

  • Why is this consider bad practice? or is it? (ASP.Net)

    - by user318573
    Would this code be considered bad practice: <div id="sidebar"> <% =DisplayMeetings(12) %> </div> This is a snippet of code from the default.aspx of a small web app I have worked on. It works perfectly well, runs very fast, but as always, I am aware of the fact that just because it works, doesn't mean it is OK. Basically, the DisplayMeetings subroutine outputs a bunch of formatted HTML (an unordered list actually), with no formatting, just the requisite html, and then my CSS performs all the necessary formatting. The data for generating the list comes from an SQL server database (the parameter controls how many rows to return) and I am using stored procedures and datareader for fast access. This keeps my front-end extraordinary simple and clean, imho, and lets me do all the work in VB or C# in a separate module. I could of course use a databound repeater (and probably 6 or more other methods) of accomplishing the same thing, but are they any better? Other than loosing the design-time features of VS2010?

  • Paging with jQuery

    I get data from another page using jQuery get method. But I have a small problem. Sometimes, data that I take from another page is too long so it's divided into pages. When the user clicks on 1, 2, 3, ... links he/she is redirected to the other page. However, I want data to be reloaded on the same page. Edit $('ul.thumbs li.pagination a').live('click', function() { var pageNumber = parseInt($(this).text().replace(/[^0-9]/g, '')); $.ajax({ type: "GET", url: "images.cs.asp?Process=ViewImages&PAGEID=<%=Request.QueryString("PAGEID")%>", success: function(data) { $("#ViewImages").html(data); }, error: function (XMLHttpRequest, textStatus, errorThrown) { $("#ViewImages").html('.'); } }); return false; });

  • How can code in a JavaScript file get the file's URL?

    I need to dynamically load a CSS stylesheet into a page that's on a different domain. How can I get the complete URL of the JS file to use in the href attribute of the stylesheet? For instance, here is the structure: http://bla.com/js/script.js http://bla.com/css/style.css I want to dynamically load the stylesheet into a page http://boo.net/index.html. The problem is, I don't know the bla.com bit in advance, just the fact that the stylesheet is in ../css/ relative to the JS file. The script is, of course, included on index.html. jQuery's fine too.
