  • Multiple inputs on a single line with Twitter Bootstrap and Simple Form 2.0

    - by noel_g
    I am using simple_form 2.0 with twitter bootstrap. I am trying to determine what is the proper wrapper format in order to get something like [city] [State] [Zip] I believe my form needs to be <div class="control-group"> <%= f.input :city,:wrapper => :small, :placeholder => "City", :input_html => { :class=>"span2", :maxlength => 10},:label => false %> <%= f.input :region, :wrapper => :small , :placeholder => "Region", :input_html => { :class=>"span1", :maxlength => 5}, :label => false %> <%= f.input :postal_code, :wrapper => :small, :placeholder => "Postal Code",:input_html => { :class=>"span2", :maxlength => 10},:label => false %> </div> I tried this wrapper config.wrappers :small, :tag => 'div', :class => 'controls inline-inputs', :error_class => 'error' do |b| b.use :placeholder b.use :label_input end I believe I would need to define the CSS as well, but before I go down a rabbit hole I thought I would ask if this is built in somewhere.

  • why doesn't IE8 refresh textbox right away?(Jquery)

    - by AndrewSmith
    I have 3 radio buttons and one textbox in my page. These 3 radio controls represent corresponding choice and among them, the third one enables textbox that is disabled by default. If user clicks any one from the first twos after clicking the third, the textbox will be emptied(if user input any) and disabled again. The problem is, in IE, the textbox isn't emptied not until I click back once again on the said textbox. I've used jquery val methods as well as attr but nothing seems to work. You can see my code as follows. The very same code works just fine in Mozilla. I'm not sure why IE is having problem. m.bind_eventform = function(){ $('input[name=poster]').change(function(){ if($('input[name=poster]:checked').val()==2) $('#poster_other').removeAttr('disabled'); else if(!($('#poster_other').is(':disabled'))) { $('#poster_other').attr('disabled','disabled'); $('#poster_other').attr('value',''); //this one doesn't work $('#poster_other').val(''); //as well as this one } }); }; $(document).ready(m.bind_eventform);

  • Styling individual radio buttons in drupal form

    - by Andrew
    I have this group of radio buttons in which each of individual button has of its own position set through style attribute. I would like to how can I archive the same by using drupal form api. I found how to style as whole but, not as individual control within group. Here's how my html code look like - <input type="radio" name="base_location" checked="checked" value="0" style="margin-left:70px;float:left;"/><span style="float:left;">District</span> <input type="radio" name="base_location" value="1" style="margin-left:50px;float:left;"/><span style="float:left;">MRT</span> <input type="radio" name="base_location" value="2" style="margin-left:60px;float:left;"/><span style="float:left;">Address</span> And this is the drupal code I'm stuck at - $form['base_location'] = array( '#type' => 'radios', '#title' => t('base location'), '#default_value' => variable_get('search_type', 0), '#options' => array( '0'=>t('District'), '1'=>t('MRT'), '2'=>t('Address')), '#description' => t('base location'), I'm aware of #type=radio existence. However, I do not know how to group all my radio buttons together in this regard. If I use same array key for all of them, they would collide each other. If I don't, they aren't seen as part of the same group. I thank you in advance.

  • jquery change event not working with IE6

    - by manivineet
    It is indeed quite unfortunate that my client still uses IE6. using jquery 1.4.2 The problem is that I open a window using a click event and do some edit operation in the new window. I have a 'change' event attached to the row of a table which has input fields. Now when the window loads for the first time and I make a change in the input for the FIRST time, the change event does not fire. however, on a second try it starts working. I have noticed that I e.g. I run a dummy page, i.e. create a new page(i work with visual studio) and run that page individually , the 'change' event works just fine. what it going on? and what can i do, besides going back to 1.3.2 (by the way that doesn't work either, but haven't fully tested it yet) <!--HTML--> <table id="tbReadData"> <tr class="nenDataRow" id="nenDr2"> <td> <input type="text" class="nenMeterRegister" value="1234" /> </td> <tr /> <table> <script type="text/javascript"> $(document).ready(function(){ $('#tbReadData').find('tr').change(function() { alert('this works'); } }); </script>

  • Syntactical analysis with Flex/Bison part 2

    - by Imran
    Hallo, I need help in Lex/Yacc Programming. I wrote a compiler for a syntactical analysis for inputs of many statements. Now i have a special problem. In case of an Input the compiler gives the right output, which statement is uses, constant operator or a jmp instructor to which label, now i have to write so, if now a if statement comes, first the first command (before the else) must be give out when the assignment of the if is yes then it must jump to the end because the command after the else isnt needed, so after this jmp then the second command must be give out. I show it in an example maybe you understand what i mean. Input adr. Output if(x==0) 10 if(x==0) Wait 5 20 WAIT 5 else 30 JMP 50 Wait 1 40 WAIT 1 end 50 END like so. I have an idea, maybe i can do it whith a special if statement like IF exp jmp_stmt_end stmt_seq END when the if statement is given in the input the compiler has to recognize the end ofthe statement and like my jmp_stmt in my compiler ( you have to download the files from http://bitbucket.org/matrix/changed-tiny) only to jump to the end. I hope you understand my problem.thanks.

  • select failing with C program but not shell

    - by Gary
    So I have a parent and child process, and the parent can read output from the child and send to the input of the child. So far, everything has been working fine with shell scripts, testing commands which input and output data. I just tested with a simple C program and couldn't get it to work. Here's the C program: #include <stdio.h> int main( void ) { char stuff[80]; printf("Enter some stuff:\n"); scanf("%s", stuff); return 0; } The problem with with the C program is that my select fails to read from the child fd and hence the program cannot finish. Here's the bit that does the select.. //wait till child is ready fd_set set; struct timeval timeout; FD_ZERO( &set ); // initialize fd set FD_SET( PARENT_READ, &set ); // add child in to set timeout.tv_sec = 3; timeout.tv_usec = 0; int r = select(FD_SETSIZE, &set, NULL, NULL, &timeout); if( r < 1 ) { // we didn't get any input exit(1); } Does anyone have any idea why this would happen with the C program and not a shell one? Thanks!

  • Problem with OnSubmit in Validation plugin in jQuery

    - by novellino
    Hello, I an quite new to jQuery and I have a problem while trying to create a form. I am using the Validation plugin for validate the email (one the form's field). When I click the Submit button I want to call my own function because I want to save the data in an XML file. This is my button: (as I understood the plugin uses "submit" for understand the button) <input type="submit" name="submit" class="submit" id="submit_btn" value="Send"/> and here is the script for the validation: <script type="text/javascript"> $(document).ready(function() { //this is my form $("#contactForm").validate(); /*save the valid data in the xml*/ $(".submit").click(function() { var email = $("input#email").val(); var subject = $("input#subject").val(); var message = $("textarea#message").val(); if (email == "" || !$("#contactForm").valid()) { return false; } var dataString = 'email='+ email + '&subject=' + subject + '&message=' + message; //alert("DATA: " +dataString); $.ajax({ type: "POST", url: "SaveData.jsp", data: dataString, success: function(data){} }); return false; }); }); </script> In general it works ok but I have two basic problems. When I click the button in the beginning having all the form empty, I get no message for the field required. Also when the data are valid and I am doing the submit, the form does not become clear after the submit. If I deleted this script code, these actions are working properly but I can not save the data! Does anyone know what is wrong? Thanks a lot!

    Hi, I am trying to send a byteArray from my .fla to my running tomcat server integrated in Eclipse.

  • adding an uncertain number of fields using javascript

    - by user306472
    I'm new to javascript and a novice programmer, so this might be a really easy question to answer. I would like to loop over the values of x number of fields and add them up to display the sum in a final field. I can perform this function if I explicitly call each field, but I want to abstract this so I can deal with a flexible number of fields. Here's example code I've come up with (that's not working for me). Where am I going wrong? <html> <head> <script type="text/javascript"> function startAdd(){ interval = setInterval("addfields()",1); } function addfields(){ a = document.addition.total.value; b = getElementByTagName("sum").value; for (i=0; i<=b.length; i++){ a+=i; } return a; } function stopAdd(){ clearInterval(interval); } </script> </head> <body> <form name="addition"> <input type="text" name="sum" onFocus="startAdd();" onBlur="stopAdd;"> + <input type="text" name="sum" onFocus="startAdd();" onBlur="stopAdd;"> = <input type="text" name ="total"> </form> </body> </html>

The basic example works, but not mine. var ppl = {"ppl":[{"name":"peterpeter", "work":"student"}, {"name":"piotr","work":"student"}]}; var options = { matchContains: true, // So we can search inside string too minChars: 2, // this sets autocomplete to begin from X characters dataType: 'json', parse: function(data) { var parsed = []; data = data.ppl; for (var i = 0; i < data.length; i++) { parsed[parsed.length] = { data: data[i], // the entire JSON entry value: data[i].name, // the default display value result: data[i].name // to populate the input element }; } return parsed; }, // To format the data returned by the autocompleter for display formatItem: function(item) { return item.name; } }; $('#inputplace').autocomplete(ppl, options); Ok. Updated: <input type="text" id="inputplace" /> So, when entering for example "peter" in the input field. No autocomplete suggestions appear. It should give "peterpeter" but nothing happens. And one more thing. Using this example works perfectly. var data = "Core Selectors Attributes Traversing Manipulation CSS Events Effects Ajax Utilities".split(" "); $("#inputplace").autocomplete(data);

  • Codeigniter: Simple ajax submit not working

    - by Kevin Brown
    jQuery: $('#welcome-message').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).ajaxSubmit({}); $(this).fadeTo(400, 0, function () { // Links with the class "close" will close parent $(this).slideUp(400); }); return false; }); Controller: function welcome_message() { if(isset($_POST['welcome_message'])) { $this-_my_private_function(); } } private function _my_private_function() { $id = $this->session->userdata('id'); $profile['welcome_message'] = '0'; $this->db->update('be_user_profiles',$profile, array('user_id' => $id)); redirect('home', 'location'); } html: <?php print form_open('home/welcome_message',array('class'=>'horizontal','id'=>'welcome-message'))?> <p> Before you can complete the assessment, you need to complete your profile. Once that's done you'll be ready! After you have completed the assessment, you will be able to view the results from your profile. </p> <input type="checkbox" value="0" name="welcome_message" checked="false"> Don't show me this again </input> <p> <input class="button submit" type="submit" class="close-box" value="Close" /> </p> <?php print form_close()?> This should be working. My hypothesis is that the data isn't being passed to the function...but I really have no idea! It works when I visit the function in the url.

  • Reading only one row from table in model binder

    - by user281180
    I am filling a table dynamically. I can see the table filled with 3 rows, but in my model binder I can read only one value. How can I solve this problem? My code is as follows: function AddTableRow(jQtable, value, text){ var count = 0; jQtable.each(function() { var $table = $(this); var tds = '<tr>'; tds += '<td>' + '<input type="text" value = ' + text + ' disabled ="disabled" style="width:auto"/>' + '<input type="hidden" name="projectList[' + count + '].ID" value = ' + value + ' /></td>' + '<td><input type="button" value="Remove"/></td>'; tds += '</tr>'; if ($('tbody', this).length > 0) { $('tbody', this).append(tds); } else { $(this).append(tds); } count++;}); } function ReadSelectedProject() { $("#Selected option").each(function() { AddTableRow($('#projectTable'), $(this).val(), $(this).text()); }); }

  • Displaying data from a linked table and displaying it as a list with HTML/PHP/MySQL

    - by user1672694
    I have three tables. students studentID | FirstName | LastName | Email | Form course CCode | Title courseenrolement courseenrolementid | studentID | ccode | complete | scode With the website, I have a page where I can view all the current enrolements and I wish to be able to view the list displaying the first name, surname and course title. I know I could do it with the following SQL (for the names): SELECT FirstName, LastName FROM student, courseenrolement WHERE courseenrolement.studentID = student.studentID But I am unsure how to get this to work using HTML/PHP. At present I only know how to display the studentID and CCode from the courseenrolement table using the following code: <ul> <?php foreach ($courseenrolements as $ce): ?> <li> <form action="" method="post"> <div> <?php htmlout($ce['studentID']); ?> <?php htmlout($ce['CCode']); ?> <input type="hidden" name="courseenrolementid" value="<?php echo $ce['courseenrolementid']; ?>"> <input type="submit" name="action" value="Edit"> <input type="submit" name="action" value="Delete"> </div> </form> </li> <?php endforeach; ?> </ul> which displays this: But I would like the names and course title. I managed to get it to show the names etc in the dropdown on the 'Add new' form, so I would assume it will be similar, but just unsure on how exactly. Thanks in advance

  • How to upload files to server using JSP/Servlet?

    - by Thang Pham
    How can I upload files to server using JSP/Servlet? I tried this: <form action="upload" method="post"> <input type="text" name="description" /> <input type="file" name="file" /> <input type="submit" /> </form> However, I only get the file name, not the file content. When I add enctype="multipart/form-data" to the <form>, then request.getParameter() returns null. During research I stumbled upon Apache Common FileUpload. I tried this: FileItemFactory factory = new DiskFileItemFactory(); ServletFileUpload upload = new ServletFileUpload(factory); List items = upload.parseRequest(request); // This line is where it died. Unfortunately, the servlet threw an exception without a clear message and cause. Here is the stacktrace: SEVERE: Servlet.service() for servlet UploadServlet threw exception javax.servlet.ServletException: Servlet execution threw an exception at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:313) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Thread.java:637)

  • Convert image color space and output separate channels in OpenCV

    - by Victor May
    I'm trying to reduce the runtime of a routine that converts an RGB image to a YCbCr image. My code looks like this: cv::Mat input(BGR->m_height, BGR->m_width, CV_8UC3, BGR->m_imageData); cv::Mat output(BGR->m_height, BGR->m_width, CV_8UC3); cv::cvtColor(input, output, CV_BGR2YCrCb); cv::Mat outputArr[3]; outputArr[0] = cv::Mat(BGR->m_height, BGR->m_width, CV_8UC1, Y->m_imageData); outputArr[1] = cv::Mat(BGR->m_height, BGR->m_width, CV_8UC1, Cr->m_imageData); outputArr[2] = cv::Mat(BGR->m_height, BGR->m_width, CV_8UC1, Cb->m_imageData); split(output,outputArr); But, this code is slow because there is a redundant split operation which copies the interleaved RGB image into the separate channel images. Is there a way to make the cvtColor function create an output that is already split into channel images? I tried to use constructors of the _OutputArray class that accepts a vector or array of matrices as an input, but it didn't work.
