  • Style all anchors except those that contain images, without adding class or id to the image tag?

    - by Deca
    With the example below, I need to add padding and background-color properties to the text anchor. I then need to exclude padding and background-color from anchors that contain images. <p> <a href="#">this is a text link that needs to be styled</a> <a href="#"><img src="image/name.jpg" alt="this needs to be excluded from styling" /></a> </p> If I have a red background and padding on my text links, I do not want that same red background and padding to appear on my linked images. The images will always be in their own anchors, not mixed with text within the same anchor. The rub is that I can not add classes or IDs to the img tags - I do not have edit control of that data. So how can I add CSS attributes to all anchors, while excluding anchors that contain images?

  • Create function in python to find the highest of all function arguments, and return the "tag" of the value.

    - by gatechgrad
    Consider the following: p1=1; p2=5; p3=7; highest=max(p1,p2,p3). The max function would return 7. I am looking to create a similar function, which would return "p3". I have created a small function (by simple comparisons) for the above example, shown below. however I am having trouble when the number of arguments go up. def highest(p1,p2,p3) if (p1p2) and (p1p3): return "p1" if (p2p1) and (p2p3): return "p2" if (p3p1) and (p3p1): return "p3". Is there a simpler way to do this

  • How is this inupt tag linking to another page?

    - by Matt
    Response.Write("<div><input type='submit' name='submit' value='Update Cart' /></div>") Response.Write("<div><input type='submit' name='submit' value='Shop More' /></div>") Response.Write("<div><input type='submit' name='submit' value='Checkout' /></div>") that is some example code from my teacher, but he hasn't answered my email in a couple days so I need some help. When you click the Update Cart button it just updates the cart page it's on, but when you click the Shop More button it links to Shop.aspx a different page, and the Checkout links to another page as well. I can't figure out how it is linking just from that code, anybody have any insights?

  • In Python, how do I remove the "root" tag in an HTML snippet?

    - by Chung Wu
    Suppose I have an HTML snippet like this: <div> Hello <strong>There</strong> <div>I think <em>I am</em> feeing better!</div> <div>Don't you?</div> Yup! </div> What's the best/most robust way to remove the surrounding root element, so it looks like this: Hello <strong>There</strong> <div>I think <em>I am</em> feeing better!</div> <div>Don't you?</div> Yup! I've tried using lxml.html like this: lxml.html.fromstring(fragment_string).drop_tag() But that only gives me "Hello", which I guess makes sense. Any better ideas?

  • Passing a outside variable into a <asp:sqldatasource> tag. ASP.NET 2.0

    - by MadMAxJr
    I'm designing some VB based ASP.NET 2.0, and I am trying to make more use of the various ASP tags that visual studio provides, rather than hand writing everything in the code-behind. I want to pass in an outside variable from the Session to identify who the user is for the query. <asp:sqldatasource id="DataStores" runat="server" connectionstring="<%$ ConnectionStrings:MY_CONNECTION %>" providername="<%$ ConnectionStrings:MY_CONNECTION.ProviderName %>" selectcommand="SELECT THING1, THING2 FROM DATA_TABLE WHERE (THING2 IN (SELECT THING2 FROM RELATED_DATA_TABLE WHERE (USERNAME = @user)))" onselecting="Data_Stores_Selecting"> <SelectParameters> <asp:parameter name="user" defaultvalue ="" /> </SelectParameters> </asp:sqldatasource> And on my code behind I have: Protected Sub Data_Stores_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs) Handles Data_Stores.Selecting e.Command.Parameters("user").Value = Session("userid") End Sub Oracle squaks at me with ORA-01036, illegal variable name. Am I declaring the variable wrong in the query? I thought external variables share the same name with a @ prefixed. from what I understand, this should be placing the value I want into the query when it executes the select. EDIT: Okay, thanks for the advice so far, first error was corrected, I need to use : and not @ for the variable declaration in the query. Now it generates an ORA-01745 invalid host/bind variable name. EDIT AGAIN: Okay, looks like user was a reserved word. It works now! Thanks for other points of view on this one. I hadn't thought of that approach.

  • Checking if a boolean column is true in MySQL/Rails

    - by Pygmalion
    Rails and MySQL: I have a table with several boolean columns representing tags. I want to find all the rows for which a specific one of these columns is 'true' (or I guess in the case of MySQL, '1'). I have the following code in my view. @tag = params[:tag] @supplies = Supply.find(:all, :conditions=>["? IS NOT NULL and ? !=''", @tag, @tag], :order=>'name') The @tag is being passed in from the url. Why is it then that I am instead getting all of my @supplies (i.e. every row) rather than just those that are true for the column for @tag. Thanks!

  • I need HTML help. I am using the FRAMESET tag and its getting complicated.

    - by Jordan
    You will need to download a 4Shared file so that I can give you all the information necessary. Problem: I am using the FRAMESET tab and I have links put in the left hand column and when clicked, they only open in that column when I want them to open up the full screen, not with a new tab though. Here is where you can get a word file with all the writing that I put in notepad for my pages. Each Word page is a different Notepad file, and there are pictures on the bottom to help understand. www.4shared.com/get/299858562/2f5cf7dd/2_HTML_help.html THANK YOU!

  • Mobile detection - Meta tag and max-device-width vs. php user agent?

    - by nimmbl
    Which form of mobile detection should I use and why? <meta name="viewport" content="width=320,initial-scale=1,maximum-scale=1.0,user-scalable=no" /> <link media="only screen and (max-device-width: 480px) and (min-device-width: 320px)" href="css/mobile.css" type= "text/css" rel="stylesheet"> <link media="handheld, only screen and (max-device-width: 319px)" href="css/mobile_simple.css" type="text/css" rel="stylesheet" /> Or include('mobile_device_detect.php'); $mobile = mobile_device_detect(); And why on earth would this: <?php if(strpos($_SERVER['HTTP_USER_AGENT'], 'iPhone') !== false) { ?> <meta name="viewport" content="width=320,initial-scale=1,maximum-scale=1.0,user-scalable=no" /> <link media="screen" href="css/mobile.css" type= "text/css" rel="stylesheet"> <?php } else { ?> <link media="screen" href="css/mobile_simple.css" type= "text/css" rel="stylesheet"> <?php } ?> ignore this css? body { background: -webkit-gradient(linear, left top, left bottom, from(#555), to(#000)); }

  • Viewing recently edited etherpads (note new 'etherpad' tag for open sourced etherpad code!)

    - by dreeves
    Prescript: The amazing etherpad was recently open sourced. Get it here: http://code.google.com/p/etherpad. This is the first question that I know of on StackOverflow about the etherpad code. If you're part of the etherpad open source community, you might want to subscribe to the RSS feed for questions tagged 'etherpad' just in case this catches on! My actual question, which assumes you have etherpad installed on your own server: First, here's a query to view recently edited pads: SELECT id,lastWriteTime,creationTime,headRev FROM PAD_SQLMETA ORDER BY lastWriteTime, headRev; Or, if you want to run it from a unix prompt: mysql -u root -pPASSWD etherpad -e "select id,lastWriteTime,creationTime,headRev from PAD_SQLMETA order by lastWriteTime, headRev" That's handy, however lastWriteTime actually gets updated every time someone so much as views a pad in their browser. I'd rather sort the pads by when they were actually last edited. There's probably a fancy SQL query involving a join with another table that would show actual last edit time. Does anyone know what that is? Alternatively, you could have a script that notices when headRev changes but that doesn't seem like the cleanest way to do it.

  • JQuery: Live <a> tag partially working second time around.

    - by BPotocki
    I have the following jquery code: $("a[id*='Add_']").live('click', function() { //Get parentID to add to. var parentID = $(this).attr('id').substring(4); //Get div. var div = $("#CreateList"); //Ajax call to refresh "CreateList" div with new XML. div.load("/AddUnit?ParentID=" + parentID); }); Basically, contained within the div is a nested unordered list with several "Add_#" links. Clicking the links uses an ajax call to recreate the list with a new node. It clears all the add links, but they are added again by the ajax call. This is why I used the .live method so newly added "Add_#" links still have the binding. This works in most cases. If I click "Add_1", the div refreshes with the new info. If I then click "Add_2", it works again as expected. The problem I'm having happens when I click "Add_1", then the page refreshes (and creates a new "Add_1" link), then I click the re-rendered "Add_1" again. It's the same link, but it was refreshed during the ajax call. When I do that, the javascript function still gets called, but the .load method doesn't work. Any ideas why this might be happening? Thanks.

  • MVC - Sanitizing data, where?

    - by dierre
    I'm using CakePHP but it's a question about the MVC pattern. I have in my form the input-text for the tags (separated by commas). To add the tags I've created a Tag model method that basically check if the tag exists and then add the new tag or just a new unit in the tag counter (the Tag model has these fields: id, name, slug, count). In the controller I explode the tags field and pass one tag at a time. The question is: where do I sanitize data? In the controller or in the model method? I think it should be in the controller because that's where I explode but in term of reusability I think I should sanitize data in the model. What do you think?

  • How to use XSLT to tag specific nodes with unique, sequential, increasing integer ids?

    - by ~otakuj462
    Hi, I'm trying to use XSLT to transform a document by tagging a group of XML nodes with integer ids, starting at 0, and increasing by one for each node in the group. The XML passed into the stylesheet should be echoed out, but augmented to include this extra information. Just to be clear about what I am talking about, here is how this transformation would be expressed using DOM: states = document.getElementsByTagName("state"); for( i = 0; i < states.length; i++){ states.stateNum = i; } This is very simple with DOM, but I'm having much more trouble doing this with XSLT. The current strategy I've devised has been to start with the identity transformation, then create a global variable which selects and stores all of the nodes that I wish to number. I then create a template that matches that kind of node. The idea, then, is that in the template, I would look up the matched node's position in the global variable nodelist, which would give me a unique number that I could then set as an attribute. The problem with this approach is that the position function can only be used with the context node, so something like the following is illegal: <template match="state"> <variable name="stateId" select="@id"/> <variable name="uniqueStateNum" select="$globalVariable[@id = $stateId]/position()"/> </template> The same is true for the following: <template match="state"> <variable name="stateId" select="@id" <variable name="stateNum" select="position($globalVariable[@id = $stateId])/"/> </template> In order to use position() to look up the position of an element in $globalVariable, the context node must be changed. I have found a solution, but it is highly suboptimal. Basically, in the template, I use for-each to iterate through the global variable. For-each changes the context node, so this allows me to use position() in the way I described. The problem is that this turns what would normally be an O(n) operation into an O(n^2) operation, where n is the length of the nodelist, as this require iterating through the whole list whenever the template is matched. I think that there must be a more elegant solution. Altogether, here is my current (slightly simplified) xslt stylesheet: <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:s="http://www.w3.org/2005/07/scxml" xmlns="http://www.w3.org/2005/07/scxml" xmlns:c="http://msdl.cs.mcgill.ca/" version="1.0"> <xsl:output method="xml"/> <!-- we copy them, so that we can use their positions as identifiers --> <xsl:variable name="states" select="//s:state" /> <!-- identity transform --> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="s:state"> <xsl:variable name="stateId"> <xsl:value-of select="@id"/> </xsl:variable> <xsl:copy> <xsl:apply-templates select="@*"/> <xsl:for-each select="$states"> <xsl:if test="@id = $stateId"> <xsl:attribute name="stateNum" namespace="http://msdl.cs.mcgill.ca/"> <xsl:value-of select="position()"/> </xsl:attribute> </xsl:if> </xsl:for-each> <xsl:apply-templates select="node()"/> </xsl:copy> </xsl:template> </xsl:stylesheet> I'd appreciate any advice anyone can offer. Thanks.

  • How do a search a table for similar records and displaying count - Ruby on Rails

    - by bgadoci
    I have created a table in my Ruby on Rails application that I am building called Tags. It is a blog application so I allow the user to associate tags with a post and do this through a :posts, :has_many = tags and Tag belongs_to :post association. Now that I have my Tags table I am trying to see how I would render the view such that it displays the tag and tag count. (it should be noted that I am trying to render this in the /views/posts/index.html.erb file). For instance, if there are 10 entries in the Tag table for tag_name Sports. How can I display Sports (10) in the view. I am not looking to do this for a specific tag but rather, somehow search the table, combine like tags and display a list of all tags with counts next to them. (I really want these to be a link to a list of posts that contain that tag but I learned early on only to ask one question at a time). Hope that makes sense.

  • Does video tag (HTML 5) injection via JavaScript work in any browsers?

    - by JoshNaro
    I'm trying to dynamically spawn a video element on a page using JavaScript. JavaScript <script type="text/javascript"> $(document).ready(function() { var video = $(document.createElement('video')) .attr('id', 'VideoElement') .attr('controls', 'controls') .attr('src', 'videopath.mp4') // Changed 'href' attribute to 'src' .css({ width: 640, height: 360 }); $('#VideoContainer').append(video); }); HTML <body> <div id="VideoContainer"></div> </body> In Firefox I get the video harness, but the actual video doesn't load. In IE8 the video harness doesn't even appear. Is HTML 5 just not supported enough to accomplish this yet? Edit: Got this to work with Artiom's fix. Looks like this works fine with Chrome and Safari. I'm using a codec Firefox doesn't support, so it doesn't work there; although I suspect it will work with a supported codec. IE8 sure enough doesn't work (high five IE).
