  • JavaScript inheritance

    - by Tower
    Hi, Douglas Crockford seems to like the following inheritance approach: if (typeof Object.create !== 'function') { Object.create = function (o) { function F() {} F.prototype = o; return new F(); }; } newObject = Object.create(oldObject); It looks OK to me, but how does it differ from John Resig's simple inheritance approach? Basically it goes down to newObject = Object.create(oldObject); versus newObject = Object.extend(); And I am interested in theories. Implementation wise there does not seem to be much difference.

  • Javascript AJAX function returns undefined instead of true / false

    - by Josh K
    I have a function that issues an AJAX call (via jQuery). In the complete section I have a function that says: complete: function(XMLHttpRequest, textStatus) { if(textStatus == "success") { return(true); } else { return(false); } } However, if I call this like so: if(callajax()) { // Do something } else { // Something else } The first is never called. If I put an alert(textStatus) in the complete function I get true, but not before that function returns undefined.

  • too much recursion in javascript with jquery mouseover

    - by Stacia
    I am a JS novice. Using some code I found here to help me with mouseover scale/rotate images but now when I try to apply it to more than one object I'm getting errors saying "too much recursion". Before the function didn't take any arguments, it just was on s_1 and it worked fine. I am tempted to just write different code for each object but that isn't very good programming practice. var over = false; $(function(){ $("#s_1").hover(function(){ over = true; swing_left_anim("#s_1"); }, function(){ over = false; }); $("#np_1").hover(function(){ over = true; swing_left_anim("np_1"); }, function(){ over = false; }); }); function swing_left_anim(obj){ $(obj).animate({ rotate: '0deg' }, { duration: 500 }); if (over) { $(obj).animate({ rotate: '25deg' }, 500, swing_right_anim(obj)); } } function swing_right_anim(obj){ $(obj).animate({ rotate: '-25deg' }, 500, swing_left_anim(obj)); }

  • Make accordeon/toggle menu using jquery or javascript

    - by Souza
    Found a solution: $('div.divname').not(':eq(0)').hide(); Check this page: http://www.iloja.pt/index.php?_a=viewDoc&docId=19 I would like to have ONLY the first text (faqtexto) open, and the one bellow, hidden on loading (by default) This is the HTML: <div class="agendarfaq"> <div class="topfaq"></div> <div class="faqtopics"><p class="textopics">Recolha e entrega, quanto tempo?</p></div> <div class="faqtexto"> Neque porro quisquam est, qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit, sed quia non numquam eius modi tempora incidunt ut labore et dolore magnam Quis autem vel eum iure reprehenderit qui in ea voluptate velit esse quam nihil molestiae consequatur, vel illum qui dolorem</div> <div class="faqtopics"><p class="textopics">Recolha e entrega, quanto tempo?</p></div> <div class="faqtexto"> Neque porro quisquam est, qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit, sed quia non numquam eius modi tempora incidunt ut labore et dolore magnam Quis autem vel eum iure reprehenderit qui in ea voluptate velit esse quam nihil molestiae consequatur, vel illum qui dolorem</div> </div> The jQuery I propose: $(".faqtopics").click(function(event) { $("div.faqtexto").slideUp(100); $(this).next("div.faqtexto").slideToggle(); }); Do you suggest any other cleaner jQuery code? Any help would be welcome! Thank you very much!

  • Getting javascript mouse position relative to website prefferably without jQuery

    - by Constructor
    I've found this snippet on Ajaxian, but I can't seem to use the cursor.y (or cursor.x) as a variable and when the function is called as such it does not seem to work. Is there a syntax problem or something else? function getPosition(e) { e = e || window.event; var cursor = {x:0, y:0}; if (e.pageX || e.pageY) { cursor.x = e.pageX; cursor.y = e.pageY; } else { cursor.x = e.clientX + (document.documentElement.scrollLeft || document.body.scrollLeft) - document.documentElement.clientLeft; cursor.y = e.clientY + (document.documentElement.scrollTop || document.body.scrollTop) - document.documentElement.clientTop; } return cursor; } I'd preffer not to use jQuery UI if possible, since I've always thaught of jQuery and librarys as a bit of an overkill for most JS programing.

  • Javascript check of a form, not waiting for ajax response

    - by Y.G.J
    this is a part of the check in my form function check(theform) { var re = /^\w[0-9A-Za-z]{5,19}$/; if (!re.test(theform.username.value)) { alert("not valid username"); theform.username.focus(); return false; } $.ajax({ type: "POST", url: "username.asp", data: "username="+theform.username.value, success: function(msg){ username = msg; if (!username) { alert("username already in use"); return false; } } }); var re = /^\w[0-9A-Za-z]{5,19}$/; if (!re.test(theform.password.value)) { alert("not valid password"); theform.password.focus(); return false; } } for some reason of sync... it check the username then duplicated username with the ajax and not waiting for respond and jump to the password check. i don't want to insert the rest of the code to isreadystate (or what ever it is) because i might move the username duplicate check to the end... and then the function will end before the ajax anyway what should i do?

  • Unfailing Javascript Image Preview

    - by Jason
    I have the following code that presents the user with a preview of the image they're trying to upload and works really well in FF: var img = document.createElement('img'); img.src = $('#imageUploader').get(0).files[0].getAsDataURL(); The problem is, getAsDataURL() only works in FF. Is there something similar/a workaround for this kind of functionality in Chrome (specifically)?

  • How to find modal dialog opener from javascript?

    - by yapiskan
    I have a page that opens a modal dialog. After the operations done on dialog I want to refresh the opener page. But when I open the popup by using "openDialog" I cannot access to the opener by using window.opener on popup page. It appears "undefined" when I wanted to access. (I dont want to use "popup" method in this case. I want it to be a dialog by the way. using "popup" is my second plan.) What is the best practice to get rid off this issue?

    - by Samuel
    I was wondering, is there a way to detect if a certain image / div is loaded? For example when i am loading two heavy images and showing a loading sign at the two places the images will later occupy, is there a way to already display the first image when it's loaded while still loading the second one?

  • SharePoint Client JavaScript Documentation

    - by G N
    I'm attempting to improve the usability of a client's SharePoint deployment via JQuery; and am hitting a brick wall when trying to find any sort of documentation of what's happening in core.js (aside from painfully digging through and trying to parse any sort of meaning out of it --all 250kb of it!!!!--) Anyone have any pointers, or documentation? EDIT: Sorry, to clarify my question, i'm familiar with using JQuery with SharePoint. My question involves hooking JQuery into SharePoint's own client API. My question is inspired by this post http://www.codefornuts.com/2009/09/forcing-sharepoint-into-asynchronous.html# ; where the author is overriding methods such as "SubmitFormPost" and "STSNavigate" in order to make the UI interaction more "AJAXy".

  • How to not use JavaScript with in the elements events attributes but still load via AJAX

    - by thecoshman
    I am currently loading HTMl content via AJAX. I have code for things on different elements onclick attributes (and other event attributes). It does work, but I am starting to find that the code is getting rather large, and hard to read. I have also read that it is considered bad practice to have the event code 'inline' like this and that I should really do by element.onclick = foobar and have foobar defined somewhere else. I understand how with a static page it is fairly easy to do this, just have a script tag at the bottom of the page and once the page is loaded have it executed. This can then attach any and all events as you need them. But how can I get this sort of affect when loading content via AJAX. There is also the slight case that the content loaded can very depending on what is in the database, some times certain sections of HTML, such as tables of results, will not even be displayed there will be something else entirely. I can post some samples of code if any body needs them, but I have no idea what sort of things would help people with this one. I will point out, that I am using Jquery already so if it has some helpful little functions that would be rather sweet¬

  • HTML element to use as a Javascript message display

    - by javanix
    I have a message display field on my website that I'd like to change the value of via JS. I've been using just a textfield, disabling it, and modifying the value via a JS function (after using a little CSS to make it not look like a text field): <input type="text" id="message" style="background: white; color: black" size="50" disabled> There has to be a better way (for instance, formatting is tricky whenever the message runs over the specified size), but I can't think of it off the top of my head. Can anyone point me in a better direction? Thanks! FYI: I am doing a timer function which I'd like to look something like "HH:MM:SS | 'my message here'"
