  • change div text on radion button click

    - by pisi
    I want to put the radio button value in the status div. The text of status div should change, according to the radio button selected by the user. The code that I used bellow is not working. Please help. Thanks! HTML code: <form action=""> <input type="radio" name="sex" value="male">Male<br> <input type="radio" name="sex" value="female">Female<br> <div id="status"></div> </form>? JS code: $(document).ready(function () { RadioStatus=""; $("input[type='radio']:checked").each( function() { if ($(this).attr('checked');) RadioStatus=$(this).val(); $("#status").text(RadioStatus); }); $("input[type='radio']").change(function() { RadioStatus= $('input[type='radio']:checked').val() $('#status').text(RadioStatus); }); });

  • Is catching NumberFormatException a bad practice?

    - by integeruser
    I have to parse a String that can assume hex values or other non-hex values 0xff, 0x31 or A, PC, label, and so on. I use this code to divide the two cases: String input = readInput(); try { int hex = Integer.decode(input); // use hex ... } catch (NumberFormatException e) { // input is not a hex, continue parsing } Can this code be considered "ugly" or difficult to read? Are there other (maybe more elegant) solutions? EDIT : I want to clarify that (in my case) a wrong input doesn't exist: i just need to distinguish if it is a hex number, or not. And just for completeness, i'm making a simple assebler for DCPU-16.

  • String.split() - matching leading empty String prior to first delimiter?

    - by tehblanx
    I need to be able to split an input String by commas, semi-colons or white-space (or a mix of the three). I would also like to treat multiple consecutive delimiters in the input as a single delimiter. Here's what I have so far: String regex = "[,;\\s]+"; return input.split(regex); This works, except for when the input string starts with one of the delimiter characters, in which case the first element of the result array is an empty String. I do not want my result to have empty Strings, so that something like, ",,,,ZERO; , ;;ONE ,TWO;," returns just a three element array containing the capitalized Strings. Is there a better way to do this than stripping out any leading characters that match my reg-ex prior to invoking String.split? Thanks in advance!

  • Re-order form fields on submit url

    - by user2521764
    I have a get form with several visible and hidden input fields. When the form is submitted, selected fileds with their values are appended to the url in the order they are placed in the form. Is there a way to re-order the parameters in the url using jQuery? Note that for the reasons of usability, I can not re-order the elements on the form itself. I know it beggs the question "why would I want to do it?", but the reason is that I will be hitting a static page, so the order of the parameters have to be exactly how they are in the static page url. For example, my form returns a url: http://someurl??names=comm&search=all&type=list while the static page has a url: http://someurl??search=all&type=list&names=comm A simplified form example is here: <form id="search_form" method="get" action="http://www.cbif.gc.ca/pls/pp/ppack.jump" > <h2>Choose which names you want to be displayed</h2> <select name="names"> <option value="comm">Common names</option> <option value="sci">Scientific names</option> </select> <h2>Choose how you want to view the results</h2> <input type="radio" name="search" value="all" id="complete" checked = "checked" /> <label for="complete" id="completeLabel">Complete list</label> <br/> <input type="radio" name="p_null" value="house" id="house" /> <label for="house" id="houseLabel">House plants only</label> <br/> <input type="radio" name="p_null" value="illust" id="illustrat" /> <label for="illustrat" id="illustratLabel">Plants with Illustrations</label> <br/> <input type="hidden" name="type" value="list" /> <input type="submit" value="Submit" /> </form> I can get form fields with values using $(#search_form).serializeArray() and massage the array like I want to, but I don't know how to set it back, i.e. modify the serialized values so that the submitted url has my order of parameters. I'm not even sure if this is the right way to go about it, so any pointers would be greatly appreciated.

  • Fastest way to move records from an Oracle database into SQL Server

    - by user347748
    Ok this is the scenario... I have a table in Oracle that acts like a queue... A VB.net program reads the queue and calls a stored proc in SQL Server that processes and then inserts the message into another SQL Server table and then deletes the record from the oracle table. We use a DataReader to read the records from Oracle and then call the stored proc for each of the records. The program seems to be a little slow. The stored procedure itself isn't slow. The SP by itself when called in a loop can process about 2000 records in 20 seconds. But when called from the .Net program, the execution time is about 5 records per second. I have seen that most of the time consumed is in calling the stored procedure and waiting for it to return. Is there a better way of doing this? Here is a snippet of the actual code Function StartDataXfer() As Boolean Dim status As Boolean = False Try SqlConn.Open() OraConn.Open() c.ErrorLog(Now.ToString & "--Going to Get the messages from oracle", 1) If GetMsgsFromOracle() Then c.ErrorLog(Now.ToString & "--Got messages from oracle", 1) If ProcessMessages() Then c.ErrorLog(Now.ToString & "--Finished Processing all messages in the queue", 0) status = True Else c.ErrorLog(Now.ToString & "--Failed to Process all messages in the queue", 0) status = False End If Else status = True End If StartDataXfer = status Catch ex As Exception

  • IE8 CSS different from IE7 & Firefox

    - by thegunner
    Hi, I'm applying a css style to a select dropdown and input textboxes. The style appears to work in IE7 and Firefox but not in IE8. The css is: input.text, input.file, textarea.textarea, select.select { font-family:"lucida grande",tahoma,verdana,arial,sans-serif; color:#333; margin:0; padding:4px; } input.text, textarea.textarea, select.select{ border-top:1px solid #7c7c7c; border-left:1px solid #c3c3c3; border-right:1px solid #c3c3c3; border-bottom:1px solid #ddd; } The style appears to apply fine to textboxed but not selects/ Any ideas about why this is happening in IE8?

  • Toggle classes with radio button in jQuery

    - by dardub
    I have a set of radio buttons where when I click a radio button, I want the label to change color or whatever. But when I click another radio button, the color goes away. Therefore I have something like this: jQuery('label').mouseup(function(){ jQuery(this).prev().attr('checked', 'checked'); jQuery('input').next().removeClass('selected'); jQuery('input:checked').next().addClass('selected'); }); if you need to see some html: <input type="radio" id="radio1" name="myRadio" value="option-1" /> <label for="radio1">Swing Gate</label> <input type="radio" id="radio2" name="myRadio" value="option-2" /> <label for="radio2">Swing Gate</label> This first removes 'selected' class from all the labels and then re-applies to only the checked labels. It works and is simple, but I was thinking this might not be the most efficient way of doing this. I imagine that javascript is iterating through each input element and using more resources than necessary. I'm curious if anyone knows of a common way of doing this more efficiently. I seem to be doing this type of thing quite often in my jQuery code. I've just been using jQuery for the past 3 months or so btw.

  • How do I make a multiple file upload?

    - by Bluemagica
    I am trying to make a multiple image uploader. The file upload fields are being added in the form dynamically using jquery. I tried making an array of the fields since I don't want to have a hidden field. so my generated upload fields look like <input type="file" id="img0" name="img[]"/> <input type="file" id="img1" name="img[]"/> <input type="file" id="img2" name="img[]"/> ..... .. And on the php side I did something like if(isset($_FILES['img'])) { foreach($_FILES['img'] as $k=>$v) { if($v!="") { uploadImage($k,0,0,0,"content/gallery/"); } } } Now I know I am way too wrong, since in that code I am looping through the 'img' file's properties instead of all images....but I have no idea how to fix this. PS: uploadImage is a function I wrote which expects the file input field's name as the first parameter.

  • can't read from stream until child exits?

    - by BobTurbo
    OK I have a program that creates two pipes - forks - the child's stdin and stdout are redirected to one end of each pipe - the parent is connected to the other ends of the pipes and tries to read the stream associated with the child's output and print it to the screen (and I will also make it write to the input of the child eventually). The problem is, when the parent tries to fgets the child's output stream, it just stalls and waits until the child dies to fgets and then print the output. If the child doesn't exit, it just waits forever. What is going on? I thought that maybe fgets would block until SOMETHING was in the stream, but not block all the way until the child gives up its file descriptors. Here is the code: #include <stdlib.h> #include <stdio.h> #include <string.h> #include <sys/types.h> #include <unistd.h> int main(int argc, char *argv[]) { FILE* fpin; FILE* fpout; int input_fd[2]; int output_fd[2]; pid_t pid; int status; char input[100]; char output[100]; char *args[] = {"/somepath/someprogram", NULL}; fgets(input, 100, stdin); // the user inputs the program name to exec pipe(input_fd); pipe(output_fd); pid = fork(); if (pid == 0) { close(input_fd[1]); close(output_fd[0]); dup2(input_fd[0], 0); dup2(output_fd[1], 1); input[strlen(input)-1] = '\0'; execvp(input, args); } else { close(input_fd[0]); close(output_fd[1]); fpin = fdopen(input_fd[1], "w"); fpout = fdopen(output_fd[0], "r"); while(!feof(fpout)) { fgets(output, 100, fpout); printf("output: %s\n", output); } } return 0; }

  • Creating a Doctrine query with a different number of ids

    - by frapet
    Is it possible to create a Doctrine query with a differnt number of ids coming from a submitted form? And if yes how? What I am trying to do is this: .... if ($input->isValid()) { $q = Doctrine_Query::create() ->from('Imm_Model_Images i') ->whereIn('i.ImageID = ?', array($input->ids)); $result = $q->fetchArray(); PS: ids come form the submitted form in an array as ids[]. Added Edit: chaged the above line: ->whereIn('i.ImageID = ?', array($input->ids)); with: ->whereIn('i.ImageID = array($input->ids)'); ...and it seems to work.

  • Handling text menu in Python

    - by PulpFiction
    Hi all. I am trying to create a text based menu in Python. Here is the code: #!/usr/bin/env python def testcaseOutput(): print '1. Add. 2. Subtract. 3. Divide. 4. Multiply' try: answer = int(raw_input('Enter a value (1 - 4) >. ')) except ValueError: print 'Invalid input. Enter a value between 1 -4 .' testcaseOutput() if answer in range(1, 5): return answer else: print 'Invalid input. Enter a value between 1 - 4.' testcaseOutput() My question: When the user enters an invalid input, i.e. not a number, I want this function to get called again. So I used the recursive approach which I think is bad design. I use that approach again in the if answer in range(1, 5). Is there any other way to handle this? I need the prompt called again when there is an invalid input. Also, is there any way I can club the two constraints: check whether input is a number and check whether the number is in the range(1,5) together? As you can see, I am checking that individually.

  • Getting all selected checkboxes in an array

    - by Click Upvote
    So I have these checkboxes: <input type="checkbox" name="type" value="4" /> <input type="checkbox" name="type" value="3" /> <input type="checkbox" name="type" value="1" /> <input type="checkbox" name="type" value="5" /> And so on. There are about 6 of them and are hand-coded (i.e not fetched from a db) so they are likely to remain the same for a while. My question is how I can get them all in an array (in javascript), so I can use them while making an AJAX $.post request using Jquery. Any thoughts? Edit: I would only want the selected checkboxes to be added to the array

  • How initialize array of classes? (C++)

    - by Kra
    Hello, I have this class constructor: Pairs (int Pos, char *Pre, char *Post, bool Attach = true); How can I initialize array of Pairs classes? I tried: Pairs Holder[3] = { {Input.find("as"), "Pre", "Post"}, {Input.find("as"), "Pre", "Post"}, {Input.find("as"), "Pre", "Post"} }; Apparently it's not working, I also tried to use () brackets instead of {} but compiler keeps moaning all the time. Sorry if it is lame question, I googled quite hard but wasn't able to find answer :/ Thanks.
