  • Dynamically writing out li with jquery. Element is not clickable after being written

    - by estern
    I have have a a function that when a checkbox is checked i dynamically write out an li into a ol that is empty. Code: $(":checkbox").click(function() { var checkedState = $(this).is(':checked'); if (checkedState == true) { var productName = $(this).attr("title"); $("#selectedProductsList").append("<li class=\"productList " + this + "\"><p class=\"removeIcon\"><img src=\"images/remove-icon.png\" alt=\"Remove Product\" /></p><span class=\"productName\">"+ productName +"</span></li>"); }; }); Then when that writes out there is a remove icon that will remove the item from the ol when clicked. This remove icon has a class of removeIcon which can be seen in the dynamic li above. I have a function that processes the remove call and then does some actions: Code: $('.removeIcon').click(function() { alert("starting"); }); Right now i have the remove action just trying to alert a message that it got called. But it seems that it is not getting into the function. Is there a certain way that i need to access these dynamic li's other then the .click method? I saw this post: Dynamically Inserted DOM Elements are not Clickable using $.click() Where they added .live vs .click but this doesn't seem to work either. Any ideas?

  • How to fetch particular element from string after splitting it, using XSLT split() ?

    - by Vijay
    Hi All, I have one query regarding XSLT functions. I am using split function to fetch values from a string. I am using separator as "*". e.g. String : {"item1*item2*item3*item4"} split function I am using is as; <xsl:template name="SplitItemsCollection"> <xsl:param name="list" select="''"/> <xsl:param name="separator" select="'*'"/> <xsl:if test="not($list = '' or $separator = '')"> <xsl:variable name="head" select="substring-before(concat($list, $separator), $separator)"/> <xsl:variable name="tail" select="substring-after($list, $separator)"/> <xsl:value-of select="$head"/> <xsl:call-template name="split"> <xsl:with-param name="list" select="$tail"/> <xsl:with-param name="separator" select="$separator"/> </xsl:call-template> </xsl:if> </xsl:template> This function returns me all the items. Is there any way to fetch particular item from these separated items ? Say I want to fetch item3. Can we do it directly ? Thanks in advance.

  • Why is my element variable always null in this foreach loop?

    - by ZeroDivide
    Here is the code: public IEnumerable<UserSummary> getUserSummaryList() { var db = new entityContext(); List<UserSummary> model = new List<UserSummary>(); List<aspnet_Users> users = (from user in db.aspnet_Users select user).ToList<aspnet_Users>(); foreach (aspnet_Users u in users) //u is always null while users is a list that contains 4 objects { model.Add(new UserSummary() { UserName = u.UserName, Email = u.aspnet_Membership.Email, Role = Roles.GetRolesForUser(u.UserName).First(), AdCompany = u.AD_COMPANIES.ad_company_name != null ? u.AD_COMPANIES.ad_company_name : "Not an Advertiser", EmployeeName = u.EMPLOYEE.emp_name != null ? u.EMPLOYEE.emp_name : "Not an Employee" }); } return model; } For some reason the u variable in the foreach loop is always null. I've stepped through the code and the users collection is always populated. The table entity for db.aspnet_Users is the users table that comes with asp.net membership services. I've only added a couple associations to it. edit : image of debugger

  • jQuery: How to reset all element positions on page?

    - by Rudi
    Hey everyone. Let's say I have a bunch of DIVs with a class of "apple", and another bunch of DIVs with a lass of "orange". All these DIVs have various positions, but I want to use a jQuery function to assign them new positions relative to their parent containers live on the page without any reloading. So, for example, how do I set all DIVs with the class of "apple" to a "top" value of "200px" relative to the parent container without reloading the page? Thanks!

  • How to initialise an array inside a struct without doing each element separately? (C++)

    - by Janet
    My questions are in the code, but basically i want to know how/if I can do the two commented out lines? I know I can do it in a constructor but I don't want to! struct foo { int b[4]; } boo; //boo.b[] = {7, 6, 5, 4}; // <- why doesn't this work? (syntax error : ']') //boo.b = {7, 6, 5, 4}; // <- or else this? (syntax error : '{') boo.b[0] = 7; // <- doing it this way is annoying boo.b[1] = 6; // : boo.b[2] = 5; // : boo.b[3] = 4; // <- doing it this way is annoying boo.b[4] = 3; // <- why does this work! (Using: C++, Visual Studio 2005.)

  • How to retain focus on an editable html after deleting an element.

    - by Lukasz
    Hello, I have a website with design mode on (aka. content editable = true) with some basic text on it. To that site I hooked up a shortcut so that at any point in the text I can insert an input box that serves me as an autocomplete. For that input however I want it to disappear right after I hit ENTER so that I can continue typing. It is an easy task to just make the input box disappear but I always loose focus from my document. I would greatly appreciate any suggestions on how to make this work?

  • Cannot create a new VS data connection in Server Explorer

    - by Seventh Element
    I have a local instance of SQL Server 2008 express edition running on my development PC. I'm trying to create a new data connection through Visual Studio Server Explorer. The steps are the following: Right click the "Data Connections" node = Choose Data Source. I select "Microsoft SQL Server" as the data source. The "Add Connection" dialog window appears. I select my local server instance = "Test connection" works fine. I select "AdventureWorks" as the database name = "Test connection" works fine. Next I hit the "Ok" button = Error message: "This server version is not supported. Only servers up to MS SQL Server 2005 are supported." I'm using Visual Studio 2008 Professional Edition. The target framework of the application is ".NET framework 3.5". I have a reference to System.Data (framework v2.0) and cannot find another version of the assembly on my system. Am I referencing the wrong assembly? How can I fix this problem?

  • How to hide an dom element after creating it on the fly with Jquery ?

    - by ismaelsow
    I am trying to build a form where users can add a text field by clicking on a "add option" button. They can also remove added fields by a "remove option" link created on the fly by Jquery, along with the text field. My code looks like this : $(document).ready(function(){ $("#add_option").click(function(){ var form = $("form"); var input_field = '<input type="text" />'; var delete_link = '<a href="#">remove</a>'; form.append(input_field + delete_link); return false; }); $("a").click(function(){ alert('clicked'); return false; }); }); This code is not working : when I click on the "add_option" button, a new text field and the "delete_link" appear. But when clicking on the "delete_link" created by JQuery, the browser follows the link instead of launching a pop-up displaying "clicked". Any idea ? Thanks !

  • How do I make JavaScript to set these element values?

    - by dmanexe
    I have two fields that need to multiply each other and fill a 3rd form's value. Here's the HTML: <input type="text" name="estimate[concrete][price]" value="" onBlur="calc_concreteprice(document.forms.mainform);" /> per SF <strong>times</strong> <input type="text" name="estimate[concrete][sqft]" value="" onBlur="calc_concreteprice(document.forms.mainform);" /> SF = <input type="text" name="estimate[concrete][quick_total]" value="" /> Here's my JavaScript: function calc_concreteprice(mainform) { var oprice; var ototal; oprice = ((mainform.estimate[concrete][sqft].value) * (mainform.estimate[concrete][price].value)); ototal = (oprice); mainform.estimate[concrete][quick_total].value = ototal; } I want the first two forms to be multiplied together and output to the third. I think my problem may be within how I am referencing the input field names, with brackets (I'm taking results from this form as an array so I'm already used to working with the results as a multi-dimensional array). Thanks for the help!

  • JQuery: How to apply css to a .wrap element?

    - by Eamonn
    My code thus far: $(".lorem img:not(.full-img)").each(function() { $(this).addClass("inline-img"); var imgWidth = $(this).prop('width'); var imgHeight = $(this).prop('height'); var imgFloat = $(this).prop('float'); $(this).wrap('<div class="inline-img-wrap" />'); if ($(this).prop("title")!='') { $('<p class="inline-img-caption">').text($(this).prop('title')).insertAfter($(this)); } }); I am searching for images within a body of text, appending their title values as captions underneath, and wrapping both img and p in a div.inline-img-wrap. That works fine. What I need help with is applying the styling of the img to the new wrapping div instead. You can see I have created vars for just this, but cannot get applying them to work. $this will always apply to the image, and <div class="inline-img-wrap" style="width:'+imgWidth+'"> doesn't work. All advice appreciated!

  • jQuery UI Droppable: Detect which draggables are dropped on an element?

    - by Rosarch
    I have the jQuery UI framework's draggable and droppable elements working. I would like to programmatically determine which draggable elements are currently dropped on which droppable elements. Is there an easy way to do this? I thought of using event listeners to detect drop and out events, then keep a dictionary or something in memory to keep track, but this seems contrived. Better ideas?

  • Can I get a WPF ListBox to inherit brushes from parent element?

    - by Jay
    My WPF window has its foreground brush set to a brush from a resource dictionary, and I want all text in the window to have this color, so I don't touch the foreground brush in anything else. Textboxes get the color Textblocks get the color Buttons get the color Listboxes do not get the color, and so neither do their contents. Is there any way to get a Listbox to behave like the other controls in this respect? Assuming not, and that this is by design, what is the rationale?
