  • JavaScript Self Executing Functions - What's the Difference?

    - by modernzombie
    I am very familiar with self executing functions from working with jQuery. (function($) { /* do stuff */ })(jQuery); Today I was reading the backbone.js source and noticed that they do this: (function() { /* do stuff */ }).call(this); Is this achieving the same thing? Would the following 2 lines of code do the same thing? (function($) { /* do stuff */ })(jQuery); (function($) { /* do stuff */ }).call(jQuery);

  • Set hidden form field values with JavaScript but request still empty

    - by tigerstyle
    HI volks, I try to set some hidden form field values with an onclick event. Ok, after I did something like this: document.getElementById('hidden_field').value = 123; I can output the value with the firebug console by entering this: alert(document.getElementById('hidden_field').value); So the values are definitely set. But now when I submit the form, the hidden field values are still empty. Do you have any idea whats going wrong? Thx for your answers.

  • Create an object with javascript reflection?

    - by acidzombie24
    I am doing something wrong. At the end of this o is empty. I want to pass in a string such as a=3&zz=5 and do o.a and o.zz to retrieve 3 and 5. How do i generate this object? function MakeIntoFields_sz(sz) { var kvLs = sz.split('&'); var o = new Array(); for (var kv in kvLs) { var kvA = kvLs[kv].split('='); var k = ''; var v = ''; if (kvA.length > 0) { k = kvA[0]; if (kvA.length > 1) v = kvA[1]; o[k] = v; } } return o; };

  • Javascript Shift+Enter (Firefox)

    - by Stephen MCGinley
    Hi guys, Had a look and found some things on this, but nothing seems to work as I'd like it. Initially I had my solution working with internet explorer and chrome, but not firefox (which is unsatisfactory for me to not have working) What I'm looking for is a simple text area, which sends data on enter key, but creates a new line on Shift+Enter. The following is what I have function goReturn(e,str) { var e = (window.Event) ? e.which : e.keyCode; if (e.shiftKey && e=="13") { document.getElementById("wall").value = document.getElementById("wall").value+"\n"; } else if(e=="13"){ // ...continue to send data } } This sends the data on enter, but also sends the data on shift and enter (which is the problem I have). Thanks for any assistance

  • HTML/Javascript - Inconsistent positioning

    - by user1473358
    I'm in the process of designing this site http://www.parisgaa.org/parisgaels and have a problem. The image slider on the homepage messes up sometimes. Most of the time it works and looks fine, but other times its positioning seems to get messed up and it appears underneath the content that should be below it (i.e. with that content overlapping the image). You should be able to replicate this in Chrome - just refresh a couple of times. I'd appreciate any help at all.

  • Javascript - Function call will not enter function body

    - by Mike S
    I have a function acting as a constructor that, when called, gets as far as the function definition in the debugger, but never to the function body. Is there a common reason this may happen that I am overlooking? Example code below: myconstructor.js function MyConstructor(optionalParam) { //this breakpoint gets hit var newobj = {}; //breakpoint never hit //code to check for null parameter //other code }; main.js var myConstructor = new MyConstructor(); There must be something I have overlooked, but I can't see what that is. Neither firefox/firebug nor VS report errors or warnings. Thanks!

  • Javascript drop down menu calculation

    - by Janis Yee
    I'm having a bit of an issue with me code. I'm trying to do a calculation from a drop down menu and then it will onChange to a textbox. I've been at it for days trying to figure it out and Googling ways to code the function. Can anyone please help or give me advice on how to approach this? function numGuest() { var a = document.getElementById("guests"); if(a.options[a.selectedIndex].value == "0") { registration.banq.value = "0"; } else if(a.options[a.selectedIndex].value == "1") { registration.banq.value = "30"; } } <select id="guests" name="guests"> <option value="0">0</option> <option value="1">1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> </select> <input type="text" id="banq" name="banq" onChange="numGuest()" disabled />

  • Can't access Elements previously created by innerHTML with Javascript/Prototype

    - by Joe Hopfgartner
    I am setting the innerHTML variable of a div with contents from an ajax request: new Ajax.Request('/search/ajax/allakas/?ext_id='+extid, { method:'get', onSuccess: function(transport){ var response = transport.responseText || "no response text"; $('admincovers_content').innerHTML=response; }, onFailure: function(){ alert('Something went wrong...') } }); The response text cotains a form: <form id="akas-admin" method="post" action="/search/ajax/modifyakas/"> <input type="text" name="formfield" value="i am a form field"/> </form> Then I call a functiont that should submit that form: $('akas-admin').request({ onComplete: function(transport){ //alert('Form data saved! '+transport.responseText) $('admincovers_content').innerHTML=transport.responseText; } }); The problem is $('akas-admin) returns null , I tried to put the form with this id in the original document, which works. Question: Can I somehow "revalidate" the dom or access elements that have been inserted with innerHTML? Edit Info: document.getElementById("akas-admin").submit() works just fine, problem is i don't want to reload the whole page but post the form over ajax and get the response text in a callback function. Edit: Based on the answers provided, i replaced my function that does the request with the following observer: Event.observe(document.body, 'click', function(event) { var e = Event.element(event); if ('aka-savelink' == e.identify()) { alert('savelink clicked!'); if (el = e.findElement('#akas-admin')) { alert('found form to submit it has id: '+el.identify()); el.request({ onComplete: function(transport){ alert('Form data saved! '+transport.responseText) $('admincovers_content').innerHTML=transport.responseText; } }); } } }); problem is that i get as far as alert('savelink clicked!'); . findelement doesnt return the form. i tried to place the save link above and under the form. both doesnt work. i also think this approach is a bit clumsy and i am doing it wrong. could anyone point me in the right direction?

  • refactor this javascript code

    - by nathanvda
    I have two click-events, that are nearly similar, but not quite. I am wondering how to refactor them best: $('.remove_fields.dynamic').live('click', function(e) { var $this = $(this); var after_removal_trigger_node = $this.closest(".nested-fields").parent(); trigger_removal_callback($this); e.preventDefault(); $this.closest(".nested-fields").remove(); trigger_after_removal_callback(after_removal_trigger_node); }); $('.remove_fields.existing').live('click', function(e) { var $this = $(this); var after_removal_trigger_node = $this.closest(".nested-fields").parent(); trigger_removal_callback($this); e.preventDefault(); $this.prev("input[type=hidden]").val("1"); $this.closest(".nested-fields").hide(); trigger_after_removal_callback(after_removal_trigger_node); }); As you can tell there is a fair bit of overlap. I am wondering what the best/nicest way would be to refactor this code.
