  • Why is this ajax call being made even though it shouldn't be

    - by user2921557
    i have this validation script im working on but cant see why im having an issue. You can see that i have a check = false / true, check before it runs the ajax call. However, even if a field is empty and check is set to false, it is still running the call. so: // JavaScript - Update Password AJAX $(document).ready(function () { // When the form is submitted $('.updatepasswordform').submit(function () { var check = true; // Get the values var password1 = $("input[name=password1]").val(); var password2 = $("input[name=password2]").val(); var newpassword = $("input[name=newpassword]").val(); /* Password Validation */ // If fields are empty if (password1 === '') { check = false; $("input[name=password1]").css('border', 'solid 2px red'); } // If fields are empty if (password2 === '') { check = false; $("input[name=password2]").css('border', 'solid 2px red'); } // If fields are empty if (newpassword === '') { check = false; $("input[name=newpassword]").css('border', 'solid 2px red'); } if (check = true) { $.ajax({ type: "POST", url: "process/updatepassword.php", data: $(".updatepasswordform").serialize(), dataType: "json", success: function (response) { /* Checks for database validation, removed for space saving */ } }); } return false; }); });

  • Send asapMail without reloading page using ajax

    - by Darren Cook
    Hi, I have a form that posts data to an aspMail file for delivery (works fine in current format), but would like to have the form data sent without having to re-direct to another page. Looks like Ajax is the way to proceed but I'm having a problem getting the setup to work. Here's how I've changed the html: Added: $('#myForm').submit(function() { $.ajax({ data: $(this).serialize(), type: $(this).attr('post'), url: $(this).attr('aspSend.asp'), success: function(response) { $('#created').html(response) } }); }); Changed the form tag from: <form name="myForm" action"aspSend.asp"> to: <form name="myForm"> but now the emails don't arrive!! Any suggestions?

  • How do you replace many characters in a regex?

    - by macca1
    I am sanitizing an input field and manually getting and setting the caret position in the process. With some abstraction, here's the basic idea: <input type="text" onkeyup"check(this)"> And javascript... function check(element) { var charPosition = getCaretPosition(element); $(element).val( sanitize( $(element).val() ) ); setCaretPosition(element, charPosition); } function sanitize(s) { return s.replace(/[^a-zA-Z0-9\s]/g, ''); } This is working fine except when a character does actually get sanitized, my caret position is off by one. Basically I'd like a way to see if the sanitize function has actually replaced a character (and at what index) so then I can adjust the charPosition if necessary. Any ideas?

  • Radio buttons being reset in FF on cache-refresh

    - by Andrew Song
    (This is technically an addendum to an earlier StackOverflow question I had posted, but my original post asked a different question which doesn't really cover this topic -- I don't want to edit my older question as I feel this is different enough to merit its own page) While browsing my website in Firefox 3.5 (and only FF3.5), I come across a page with two radio buttons that have the following HTML code: <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/> This page renders as expected, with 'check1' checked and 'check2' unchecked. When I then go to refresh the page by pressing Control + R, the two radio buttons render, but they are both unchecked even though the raw HTML code is the same (as above). If I do a cache-miss refresh (via Control + F5 or Control + Shift + R), the page returns back to the way you'd expect it. This is not a problem in any other browser I've tried except FF3.5. What is causing these radio buttons to be reset on a normal refresh? How can I avoid this?

  • Cannot set focus on input field in infoWindow

    - by thomas
    Hi Why is focus not set to noteTitle? I am using google maps API V3. The getNoteForm() returns a input field "noteTitle". The $("#noteTitle").focus() works fine when executed in firebug. I call this function when clicking on the map: function setNewNoteInfowindow(latlng) { if (geocoder) { geocoder.geocode({'latLng': latlng}, function(results, status) { var address = ""; if (status == google.maps.GeocoderStatus.OK) { if (results[1]) { address = results[1].formatted_address; } } newNoteInfowindow = new google.maps.InfoWindow({ content: getNoteForm(latlng, address), size: new google.maps.Size(40,50) }); newNoteInfowindow.open(map, newNoteMarker); google.maps.event.addListener(newNoteInfowindow, 'domready', function() { $("#noteTitle").focus(); }); google.maps.event.addListener(newNoteInfowindow, 'closeclick', function() { newNoteMarker.setVisible(false); }); }); } }

  • Does this incorporate JavaScript closures?

    - by alex
    In trying to learn JavaScript closures, I've confused myself a bit. From what I've gathered over the web, a closure is... Declaring a function within another function, and that inner function has access to its parent function's variables, even after that parent function has returned. Here is a small sample of script from a recent project. It allows text in a div to be scrolled up and down by buttons. var pageScroll = (function() { var $page, $next, $prev, canScroll = true, textHeight, scrollHeight; var init = function() { $page = $('#secondary-page'); // reset text $page.scrollTop(0); textHeight = $page.outerHeight(); scrollHeight = $page.attr('scrollHeight'); if (textHeight === scrollHeight) { // not enough text to scroll return false; }; $page.after('<div id="page-controls"><button id="page-prev">prev</button><button id="page-next">next</button></div>'); $next = $('#page-next'); $prev = $('#page-prev'); $prev.hide(); $next.click(scrollDown); $prev.click(scrollUp); }; var scrollDown = function() { if ( ! canScroll) return; canScroll = false; var scrollTop = $page.scrollTop(); $prev.fadeIn(500); if (scrollTop == textHeight) { // can we scroll any lower? $next.fadeOut(500); } $page.animate({ scrollTop: '+=' + textHeight + 'px'}, 500, function() { canScroll = true; }); }; var scrollUp = function() { $next.fadeIn(500); $prev.fadeOut(500); $page.animate({ scrollTop: 0}, 500); }; $(document).ready(init); }()); Does this example use closures? I know it has functions within functions, but is there a case where the outer variables being preserved is being used? Am I using them without knowing it? Thanks Update Would this make a closure if I placed this beneath the $(document).ready(init); statement? return { scrollDown: scrollDown }; Could it then be, if I wanted to make the text scroll down from anywhere else in JavaScript, I could do pageScroll.scrollDown(); I'm going to have a play around on http://www.jsbin.com and report back

  • Making a Javascript game, Having a little problem with scrolling.

    - by RobertWHurst
    I have a #wrapper div and a #grid div nested inside. currently I can scroll around with this function below. getCursorPos : function(){ // set the empty cursor object var cursor = {}; //get the offset from the left of the grid container var grid //offset loop $(function getCursorPos(){ grid = $('#grid').offset(); setTimeout(getCursorPos, game.loopSpeed); }); //continuosly get the position var that = this; $(document).mousemove(function(e){ //if game mode is menu exit if(game.mode === 'menu'){ return; } // NOTE: this looks a litle over done but don't remove anything // its like this because javascript uses floating points // and so in order to line up to the nearest hunderedth I // had to make the cursor and div position intergers by // muliplying by ten. one the two are added I reduced them // and rounded them. that.x = Math.round(((e.pageX * 10) - (grid.left * 10)) / 10); that.y = Math.round(((e.pageY * 10) - (grid.top * 10)) / 10); }); }, the problem is that the mouse coordinates only update when the mouse moves. is there any way to get the coordinates with out moving the mouse?

  • Display/Hide part of a list

    - by superexsl
    Hi I have an (unordered)list (generated by a repeater) of items. However, I'd like to show the first three items, and have the rest hidden by the main content div. When a button is pressed, I would like the list's div to expand, pushing the main content div down and showing the rest of the list. I was thinking of using slideDown(), but that closes the entire div ( and I would like to show the first 3 items of the list). What would be the best way to achieve an effect like this? Is there a plugin that can easily show X items of a list and the display the rest upon request? Thanks

  • Jsonp cross-domain ajax

    - by Guillaume le Floch
    I'm working on an application which use ajax call to get html from the server. When I run it on the server, everything works fine. But when I'm running on a localhost, I've a 'Access-Control-Allow-Origin' error. I looked arround and it seems like using jsonp could be the solution. So, my ajax call looks like that: $.ajax({ url: url, dataType: 'jsonp', crossDomain: true, type: 'GET', success: function(data){ // should put the data in a div }, error: function(){ //do some stuff with errors } }); I get html from the server, but I always have this error: Uncaught SyntaxError: Unexpected token < Is there a way to wrap the jsonp response in html? Thanks!

  • Good JavaScript engine for animating via Sprite Sheets (not in canvas)

    - by N. Taylor Mullen
    I've looked around a bit for a great JavaScript Sprite Sheet animator lib/engine but couldn't find any good ones so I thought I'd ask around =). What I'm looking for in the engine is: Animate an image in a non-canvas setting (ex: div via css or img tags) Control frame rate/animation speed Flags to loop or to animate once etc. Are there any engines like this out there? If not I can always make my own but then again, I don't want to re-invent the wheel =].

  • Will dynamicaly generated content via Javascript hurt SEO

    - by Luke101
    This is what I would like to do. I would like to load content dynamically. Everything except the actual content will be rendered by javascript. I will place all the require information in a javascript variable or array at the bottom of the page. Then I will use javascript to place the content in the designated area. These are the types of things I would like javascript to render: Login menu Header and logo info Side bar info Footer info Dialog popups Ads All of the MEAT content will not be rendered by javascript. I will use the backend server to put the content in html. My logic is that more of the real content will be in HTML and all the other things will be rendered by javascript. Will this help or hurt SEO?

  • regex not working "within" javascript string

    - by Tim
    I'm trying to replace all mentions of [b] in a text string and replace it with <b>. The problem with what I'm using below this that it's replace every [b] on the page, and I only want it to change the [b]'s within the text string ("text") that I'm sending in. Taking out the 'g' for global in the regex doesn't work very well because it then doesn't replace them all... text = text.replace(new RegExp('(^|\\s|>)\\[b](\\S.*?\\S)\\[/b]($|\\s|<)', 'gim') , '$1<strong>$2</strong>$3'); any ideas? Thanks

  • preventing jCarousel form returning to begining position after loading page

    - by Crippletoe
    Hi all, i am using jCarousel as a menu in my website. there is a list of links there which is longer than its containing elements and jCarousel is used as a scroll bar to view that list. my problem is that whenever a link is clicked and a new page is loaded, jCarousel resets to its begining position thus sometimes an active link is no longer visible after the page reloads. any idea how i can make jCarousel focus on the specific active link? you can see an example of what i mean here: http://174.133.190.8/~goldarch/index.php?option=com_content&view=article&id=50&Itemid=57 (check out the menu on top) thank you all.

  • Dependent Dropdowns with single class element

    - by AJ
    I am trying to create multiple dependent dropdowns (selects) with a unique way. I want to restrict the use of selectors and want to achieve this by using a single class selectors on all SELECTs; by figuring out the SELECT that was changed by its index. Hence, the SELECT[i] that changed will change the SELECT[i+1] only (and not the previous ones like SELECT[i-1]). For html like this: <select class="someclass"> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="mercedes">Mercedes</option> <option value="audi">Audi</option> </select> <select class="someclass"> </select> <select class="someclass"> </select> where the SELECTs other than the first one will get something via AJAX. I see that the following Javascript gives me correct value of the correct SELECT and the value of i also corresponds to the correct SELECT. $(function() { $(".someclass").each(function(i) { $(this).change(function(x) { alert($(this).val() + i); }); }); }); Please note that I really want the minimum selector approach. I just cannot wrap my head around on how to approach this. Should I use Arrays? Like store all the SELECTS in an Array first and then select those? I believe that since the above code already passes the index i, there should be a way without Arrays also. Thanks a bunch. AJ

  • Using $.getJSON to perform cross domain request problem.

    - by Ahmed
    I'm using the following code to make cross domain request using $.getJSON, request completed but with errors, I cannot exactly detect what is the thrown error. Based on callback param of request value I route it to a certain method which retrieves required JSON data. $.getJSON("http://wthsrvr:45452/Handler.ashx/?Callback=DocumentReadStatus", { userID: vuserID, documentID: vdocumentID, format: "json" }, function(result) { if (result.readStatus == '1') { alert("ACCEPTED"); } else if (result.readStatus == '0') { alert("NOT ACCEPTED"); } else { alert(result.readStatus); } }); FYI: while development of this locally, everything worked fine, but after solution deployment to server and trying to do the same, I got that problem. Also, I tried the same functionality with web service, I got the same problem while calling web service from server. I'm using ajaxSetup to detect thrown errors. $.ajaxSetup({ "error": function(XMLHttpRequest, textStatus, errorThrown) { alert("textStatus: " + textStatus); alert("errorThrown: " + errorThrown); alert("responseText: " + XMLHttpRequest.responseText); } });
