  • Restrict confirm message on page reload with f5

    - by Max
    In my JSP page I am using post method while submitting the page. So once I go from Page 1 to page 2. In Page 2, If I press F5 I am getting alert as "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." I knew this question is a bit sarcastic but please give me an Idea. I can't change my method from POST to GET because I need to send large amount of data. Thanks in advance... Edited: In my Page1.JSP I call onClick function in that function I call action as "/page2servlet.do". Now, In Java side I use Spring Framework. With MVC Object I return to page2.jsp. So where do the response.sendRedirect Fit.

  • Replace Emails and HREFS with enclosing HREFS in C#

    - by Nissan Fan
    I have an Email body that used to be plain text, but now I've made it HTML. The emails are generated using a number of methods and none of them are easy to convert. What I have is: Some content [email protected], some http://www.somewebsite/someurl.aspx. What I'd like to do is create a function that automatically encloses all email addresses and all URLs withing a string in HREF tags so that the HTML email reads properly in all email clients. Does anyone have a function for this?

  • [JQuery] Edit Css with animation effect

    - by Pennywise83
    Hi, I've a div in a absolute position with a default "top" value set to "-200px". When i click on the div the "top" value is updated to "0". In this way I see the entire Div. This is the js: $(document).ready(function(){ $("#search_bar").click(function () { $(this).css("top","0"); }); }); Is there a way to achieve this result but with an animation? For example, a slide down effect? Also, when i click another time to the div I'd like that the "top" value will be restored to "-200px".

  • Merging $.get and $.ready

    - by cwolves
    Put simply I have an ajax call that sometimes completes before the page is loaded, so I tried wrapping the callback in $( fn ), but the callback doesn't fire if the page is loaded... Anyone have a good solution to this? $.get( '/foo.json', function( data ){ $( function(){ // won't get here if page ready beats the ajax call // process data $( '.someDiv' ).append( someData ); } ); } ); And yes, I know that if I flipped the order of those it would always work, but then my ajax calls would be needlessly deferred until the document is ready.

  • How come $(this) is undefined after ajax call

    - by JohnnyQ
    I am doing an ajax request when an anchor tag is clicked with an ID set to href. Btw, this anchor tag is dynamically created. <a href="983" class="commentDeleteLink">delete</a> When the anchor tag is clicked the following code is executed: $('.commentDeleteLink').live('click', function(event) { event.preventDefault(); var result = confirm('Proceed?'); if ( result ) { $.ajax({ url: window.config.AJAX_REQUEST, type: "POST", data: { action : 'DELCOMMENT', comment : $('#commentText').val(), comment_id : $(this).attr('href') }, success: function(result) { alert($(this).attr('href')); //$(this).fadeOut(slow); } }); } }); When I tried to display $(this).attr('href') it says it's "undefined". What I really want to do is fadeOut the anchor tag but when I investigated the value of $(this) it is "undefined". What could be wrong with the snippet above?

  • How to trigger notification code TBN_TOOLBARCHANGE from inside c++ program?

    - by karikari
    Hi. How to trigger TBN_TOOLBARCHANGE from inside my c++ code? Is it the same as writing like this line below? SendMessage(m_hWndToolbar, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); Inside this project's code there is this line inside one the header file: BEGIN_MSG_MAP(CRebarHandler) NOTIFY_CODE_HANDLER(TBN_DROPDOWN, onNotifyDropDown) NOTIFY_CODE_HANDLER(TBN_TOOLBARCHANGE, onNotifyToolbarChange) NOTIFY_CODE_HANDLER(NM_CUSTOMDRAW, onNotifyCustomDraw) NOTIFY_CODE_HANDLER(TBN_ENDADJUST, onNotifyEndAdjust) MESSAGE_HANDLER(WM_SETREDRAW, onSetRedraw) END_MSG_MAP() It has already defined that for each TBN_TOOLBARCHANGE call, it will trigger the function onNotifyToolbarChange. For this example, it is triggered by IE. Inside my code, I need to trigger that particular function. And before that I need to trigger the TBN_TOOLBARCHANGE`. I just want to know how can it be done inside code, for example under a conditional statement.

  • Checking for multiple images loaded

    - by Stanni
    Hi, I'm using the canvas feature of html5. I've got some images to draw on the canvas and I need to check that they have all loaded before I can use them. I have declared them inside an array, I need a way of checking if they have all loaded at the same time but I am not sure how to do this. Here is my code: var color = new Array(); color[0] = new Image(); color[0].src = "green.png"; color[1] = new Image(); color[1].src = "blue.png"; Currently to check if the images have loaded, I would have to do it one by one like so: color[0].onload = function(){ //code here } color[1].onload = function(){ //code here } If I had a lot more images, Which I will later in in development, This would be a really inefficient way of checking them all. How would I check them all at the same time?

  • what is the purpose of numeric/boolean/string objects as opposed to primitive values?

    - by zespri
    In javascript you can call a function as a function or as a constructor. For example you can do : myObject = new Number(13); myPrimitiveValue = Number(13); or simply myPrimitiveValue = 13; I understand the difference between the results. Can you explain me under which reasonable circumstances creating a number, a boolean or a string as an object is desirable? For example, ability to set new properties (this is something you can do on objects but can't really do on primitive values) is almost always a bad idea for objects containing number/boolean/string. Why would I want a numeric/boolean/string object?

  • A 3-D grid of regularly spaced points

    - by Jack
    I want to create a list containing the 3-D coords of a grid of regularly spaced points, each as a 3-element tuple. I'm looking for advice on the most efficient way to do this. In C++ for instance, I simply loop over three nested loops, one for each coordinate. In Matlab, I would probably use the meshgrid function (which would do it in one command). I've read about meshgrid and mgrid in Python, and I've also read that using numpy's broadcasting rules is more efficient. It seems to me that using the zip function in combination with the numpy broadcast rules might be the most efficient way, but zip doesn't seem to be overloaded in numpy.

  • A little javascript help needed here (easy).

    - by Camran
    function addOption(selectbox, val, txt){ ...... } addOption(list, "Cars", "Cars"); I need to add this in front of the text of the function: &nbsp;&nbsp;&nbsp; So that there is space coming in before the option text...Never mind what it is for, it is just confusing... I just don't know how to insert it into the js code. If I do it like this: addOption(list, "Cars", "&nbsp;&nbsp;&nbsp;Cars"); Then the &nbsp;&nbsp;&nbsp; comes into the text, so it gets displayed for the users. However I need it to be interpreted as "space"... If you don't understand let me know... How can I do this? Quotes, double quotes etc? Thanks

  • How to change the opacity (alpha, transparency) of an element in a canvas element after it has been

    - by Joe Lencioni
    Using the HTML5 <canvas> element, I would like to load an image file (PNG, JPEG, etc.), draw it to the canvas completely transparently, and then fade it in. I have figured out how to load the image and draw it to the canvas, but I don't know how to change its opacity once it as been drawn. Here's the code I have so far: var canvas = document.getElementById('myCanvas'); if (canvas.getContext) { var c = canvas.getContext('2d'); c.globalAlpha = 0; var img = new Image(); img.onload = function() { c.drawImage(img, 0, 0); } img.src = 'image.jpg'; } Will somebody please point me in the right direction like a property to set or a function to call that will change the opacity? Thanks!

  • jQuery.post not working when using data type json

    - by swift
    I have been trying to utilize json in this jQuery.post because I need to return two values from my executed php. The code was working when I was not implementing json. I need to see if a promo code entered is valid for a particular broker. The two variables I need back are the instant message whether or not it's valid (this is displayed to the user) and I need to update a hidden field that will be used later while updating the database. The jQuery.post does not seem to be firing at all, but the code directly above it (the ajax-loader.gif) is working. I did re-write the whole thing at one point using jQuery.ajax, and had issues there too. Granted, I have probably been looking at this too long and have tried to re-write too many times, but any help is greatly appreciated!! Here's the jQuery.post <!-- Below Script is for Checking Promo Code Against Database--> <script type="text/javascript"> jQuery(document).ready(function() { jQuery("#promocode").keyup(function (e) { //removes spaces from PromoCode jQuery(this).val(jQuery(this).val().replace(/\s/g, '')); var promocode = jQuery(this).val(); var brokerdealerid = document.getElementById("BrokerDealerId").value; if(promocode.length > 0 ){ jQuery("#promo-result").html('<img src="../imgs/ajax-loader.gif" />'); jQuery.post( '../check_promocode.php', {promocode:promocode, brokerdealerid:brokerdealerid}, function(data) { $("#promo-result").html(data.promoresult); $("#promo-result-valid").html(data.promovalid); }, "json"); } }); }); </script> <!-- End Script is for Checking Promo Code Against Database--> Here's relevant code from check_promocode.php: //sanitize incoming parameters if (isset($_POST['brokerdealerid'])) $brokerdealerid = sanitizeMySQL($_POST['brokerdealerid']); $promocode = sanitizeMySQL($promocode); //check promocode in db $results = mysql_query("SELECT PromotionCodeIdentifier FROM PromotionCode WHERE PromotionCodeIdentifier='$promocode' AND BrokerDealerId='$brokerdealerid' AND PromotionCodStrtDte <= CURDATE() AND PromotionCodExpDte >= CURDATE()"); //return total count $PromoCode_exist = mysql_num_rows($results); //total records //if value is more than 0, promocode is valid if($PromoCode_exist) { echo json_encode(array("promoresult"=>"Promotion Code Valid", "promovalid"=>"Y")); exit(); }else{ echo json_encode(array("promoresult"=>"Invalid Promotion Code", "promovalid"=>"N")); exit(); }
