  • MySQL select one field from table WHERE condition is in multiple rows

    - by Alex
    Tried to find the answer, but still couldn't.. The table is as follows: id, keyword, value 1 display 15.6 1 harddrive 320 1 ram 3 So what i need is something like this.. Select an id from this table where (keyword="display" and value="15.6") AND (keyword="harddrive" and value="320") There's also a possibility that there will be 3 or 4 such keyword conditions which should result into returning one id (one row) It seems there's something to deal with UNION but i didn't use it before so i can't figure it out Thanks in advance

  • Using h:outputFormat to message-format the f:selectItems of a h:selectOneRadio

    - by msharma
    I am having some trouble with using h:selectOneRadio. I have a list of objects which is being returned which needs to be displayed. I am trying something like this: <h:selectOneRadio id="selectPlan" layout="pageDirection"> <f:selectItems value="#{detailsHandler.planList}" /> </h:selectOneRadio> and planList is a List of Plans. Plan is defined as: public class Plan { protected String id; protected String partNumber; protected String shortName; protected String price; protected boolean isService; protected boolean isOption; //With all getters/setters } The text that must appear for each radio button is actually in a properties file, and I need to insert params in the text to fill out some value in the bean. For example the text in my properties file is: plan_price=The price of this plan is {0}. I was hoping to do something like this: <f:selectItems value="<h:outputFormat value="#{i18n.plan_price}"> <f:param value="#{planHandler.price}"> </h:outputFormat>" /> Usually if it's not a h:selectOneRadio component, if it's just text I use the h:outputFormat along with f:param tags to display the messages in my .property file called i18n above, and insert a param which is in the backing bean. here this does not work. Does anyone have any ideas how I can deal with this? I am being returned a list of Plans each with their own prices and the text to be displayed is held in property file. Any help much appreciated. Thanks!

  • JQuery - .position isn't returning offset relative to parent.

    - by Spines
    I'm using .position to find the offset of where the element is relative to the parent, however it seems to be returning a value that is the offset from some parent up the ancestor tree. I have a button, and its wrapped withing a div and its the only element of that div. The div is floated right. .position is returning a value like {left:780, top:370}, when the true value should be around {left:200, top:0}. I'm using jquery 1.4

  • Jquery, how to escape quotes

    - by Sandro Antonucci
    I'm using a simple jquery code that grabs html code form a tag and then puts this content into a form input <td class="name_cat" ><span class="name_cat">It&#039;s a &quot;test&quot; </span> (5)</td> jquery gets the content into span.name_catand returns it as It's a "test". So when I print this into an input it becomes <input value="It's a "test"" /> which as you can imagine will only show as It's a , the following double quote will close the value tag. What's the trick here to keep the original string while not showing utf8 code in the input? Jquery code $(".edit_cat").click(function(){ tr = $(this).parents("tr:first"); id_cat = $(this).attr("id"); td_name = tr.find(".name_cat"); span_name = tr.find("span.name_cat").html(); form = '<form action="/admin/controllers/edit_cat.php" method="post" >'+ '<input type="hidden" name="id_cat" value="'+id_cat+'" />'+ '<input type="text" name="name_cat" value="'+span_name+'" />'+ '<input type="submit" value="save" />'+ '</form>'; td_name.html(form); console.log(span_name); } ); I basically need html() not to decode Utf8

  • Is there a better way to minimize this C# event repetition?

    - by Damien Wildfire
    I have a lot of code like this: public class Microwave { private EventHandler<EventArgs> _doorClosed; public event EventHandler<EventArgs> DoorClosed { add { lock (this) _doorClosed += value; } remove { lock (this) _doorClosed -= value; } } private EventHandler<EventArgs> _lightbulbOn; public event EventHandler<EventArgs> LightbulbOn { add { lock (this) _lightbulbOn += value; } remove { lock (this) _lightbulbOn -= value; } } // ... } You can see that much of this is boilerplate. In Ruby I'd be able to do something like this: class Microwave has_events :door_closed, :lightbulb_on, ... end Is there a similar shorter way of removing this boilerplate in C#?

  • Way around ASP.NET session being shared across multiple tab windows

    - by ace
    I'm storing some value in an asp.net session on the first page. On the next page, this session value is being read. However if multiple tabs are opened and there are multiple page 1-page 2 navigation going on, the value stored in session gets mixed up since the session is shared between the browser tabs. I'm wondering what are the options around this : Query String: Passing value between the pages using query string, I don't want to take this approach since there can be multiple anchor tags on page 1 linking to page 2 and I can not rewrite the URLs of each tag since they are dynamic. Cookies??? In-memory cookies are shared across browser tabs too, same as the session cookie, rite ? Any other option?

  • creating a table based on fields from three different tables

    - by ozlem
    Hi, I am using MS-Access 2003. I have three tables containing values of w,Q and L. In the Q table I have three fields: country_name, ISIC_code, and Q value. In the L table, there are three fields, country_name, ISIC_code, and L value. And in the w table there are two fields; country_name and w value. Country_names, and ISIC_code might be different for each table. What I want to do is create a new table with the values b(j)=w(i)L(ij)/Q(ij), where i is the country and j is the ISIC_code. So first I will check if the country name and ISIC_code are the same in L and Q tables. If they are equal I will calculate L/Q and then multiply this with w value of the same country if it exists. I appreciate any help.

  • C# (ASP.Net) Linking selection values to constants in Codebehind

Question: So what is the correct way to tie an dropdown/radio buttion/... ASPX value to a constant that is shared with the CodeBehind code? I know that I could do rbServer.Add.Item("developer") [from the CodeBehind], but is there a way to achieve it from the Presentation side of things?

  • How can I get all the checked items from a submitted form with sinatra's params?

    - by 102405176597896213397
    I'm running Sinatra 1.0 with HAML, my form has a number of checkboxes, for example books I like, and you would select all the books you want. The checkbox name is "books". In sinatra params['books'] there should be an array of all the books that were checked, but it only has the last item that was checked, not an array. How can I get all the checked items? HAML: %form{:action => "/test", :method => 'post'} %input{:name=>'check',:type=>'checkbox',:value=>'item1'} item 1 %input{:name=>'check',:type=>'checkbox',:value=>'item2'} item 2 %input{:name=>'check',:type=>'checkbox',:value=>'item3'} item 3 %input{:type => "submit", :value => "send", :class => "button"} Sinatra get method post '/test' do puts params['check'] #should be an array but is last item checked end

  • Has anyone used ever Mangoslick from themeforest?

    - by bonesnatch
    I was assigned to integrate MangoSlick theme to our current admin panel, Its a jQuery, Slick(?) and Responsive template. First, let me explain how the API goes In the documentation, it only says this is the only way data-[options]=[value] Example: If I wanna make a progress bar I can use this format <div class="progress"> <div class="bar" data-title="[title]" data-value="[value]" data-max="[max]" data-format="[format string]"></div> </div> so filling-in values <div class="progress"> <div class="bar" data-title="Space" data-value="1285" data-max="5120" data-format="0,0 MB"></div> </div> I will have this as output Now, the main question is when I use jQuery attr() to change the attribute values for data-title, data-max, data-value and data-format. Why is it not working? <script> var jq = $.noConflict(); jq(document).ready(function(){ jq('#bokz').attr("data-title", "No Space"); }); </script> Using the script above and inspect element in chrome the values are changed but not in the progressbar Some of you may have some ideas on this? Any help/suggestion would be very much appreciated.

What I'm doing wrong? Any idea? Sorry about code, I will change it later :)

  • Cascading dropdowns

    - by SnowJim
    Hi! I am working with cascading dropdowns in MVC. It appears that I will not be able to easily create dropdowns on demand, instead I will have to add the dropdowns before sending it to the client. This is how I am doing it right now: In the aspx page <%: Html.DropDownListFor(model => model.ModelViewAd.Category1, Model.ModelViewAd.Category1List, "-- Välj kategori --")%> <%: Html.DropDownListFor(model => model.ModelViewAd.Category2, Model.ModelViewAd.Category2List, "-- Välj kategori --")%> <%: Html.DropDownListFor(model => model.ModelViewAd.Category3, Model.ModelViewAd.Category3List, "-- Välj kategori --")%> <%: Html.DropDownListFor(model => model.ModelViewAd.Category4, Model.ModelViewAd.Category4List, "-- Välj kategori --")%> This is rendered like this : <select id="ModelViewAd_Category1" name="ModelViewAd.Category1"> <option value="">-- V&#228;lj kategori --</option> <option value="10">Fordon</option> <option value="15">F&#246;r hemmet</option> <option value="17">Bostad</option> </select> <select id="ModelViewAd_Category2" name="ModelViewAd.Category2"> <option value="">-- V&#228;lj kategori --</option> </select> <select id="ModelViewAd_Category3" name="ModelViewAd.Category3"> <option value="">-- V&#228;lj kategori --</option> </select> <select id="ModelViewAd_Category4" name="ModelViewAd.Category4"> <option value="">-- V&#228;lj kategori --</option> </select> This is what the script on the page looks like: <script type="text/javascript"> $(function () { $("select#ModelViewAd_Category1").change(function () { var id = $(this).val(); var urlAction = "/AdCategory/GetCategoriesByParent1/" + id; $.getJSON(urlAction, { id: id }, function (data) { $("#ModelViewAd_Category2").addItems(data.d); }); }); $("select#ModelViewAd_Category2").change(function () { var id = $(this).val(); var urlAction = "/AdCategory/GetCategoriesByParent1/" + id; $.getJSON(urlAction, { id: id }, function (data) { $("#ModelViewAd_Category3").addItems(data.d); }); }); $("select#ModelViewAd_Category3").change(function () { var id = $(this).val(); var urlAction = "/AdCategory/GetCategoriesByParent1/" + id; $.getJSON(urlAction, { id: id }, function (data) { $("#ModelViewAd_Category4").addItems(data.d); }); }); }); </script> And then I have an included file that contains this: $.fn.clearSelect = function () { return this.each(function () { if (this.tagName == 'SELECT') this.options.length = 0; }); } $.fn.addItems = function (data) { return this.clearSelect().each(function () { if (this.tagName == 'SELECT') { var dropdownList = this; $.each(data, function (index, optionData) { var option = new Option(optionData.Text, optionData.Value); if ($.browser.msie) { dropdownList.add(option); } else { dropdownList.add(option, null); } if ($(this).children().size() < 2) { $(this).hide(); } else { $(this).show(); } }); } }); } The problem I now have is that I need to hide the dropdowns that do not contain any options or only contain one option. This should be checked when doing a call to the service as well as when the page is sent to the client ("POSTBACK"). What I need is : 4 Dropdowns Only the first dropdown is visible when first entering the page. When selecting an option from dropdown1 the dropdown2 will be populated and so on If there is only 1 option then the dropdown should be hidden If all 4 dropdowns are set and the end-user changes dropdown1, then dropdown2 should be reloaded and the rest be hidden If the user has selected some of the dropdowns (say 1, 2 and 3) and hit submit and the page is not accepted on the server side (not valid) the dropdowns should be set exactly as when the user clicked the submit button when the page returns to the user. Any suggestions on this?
