  • Jump to an anchor link on function complete in jQuery?

    - by nick92675
    I have a simple slidetoggle function that opens onclick. What I'd like to do is jump the user down to the bottom of the page following the opened div. Basically, wait for the slidetoggle to complete - then imagine clicking my jump link to pull the viewport down. Here's my code. $('#clickme').click(function() { $('#form-area').slideToggle('slow', function() { // Animation complete // what can i put here that's like my standard jumpto? }); }); <a href="#form-bottom" id="clickme">Click here</a> <div class="main" id="form-area" > Stuff </div> <a name="form-bottom"></a>

  • Main page content populated on the fly?

    - by jcovert
    Is there any reason to NOT have a webpage retrieve it's main content on the fly? For example, I have a page that has a header and a footer, and in the middle of this page is an empty div. When you click on one of the buttons in the header, an http GET is done behind the scenes and the .innerHTML() of the empty div is replaced with the result. I can't think of any reason why this might be a bad idea, but I can't seem to find any pages out there that do it? Please advise!

  • referencing desired objects in namespaced functions

    - by RyOnLife
    I'm having trouble referencing the desired object when I've namespaced functions. No problems here: obj.test = function() { // this == obj } But I'm getting tripped up when I namespace: obj.namespace.test = function() { // this == namespace } In the latter example, I know this references namespace, but I want to reference obj. How can I do it?

  • closure not working

    - by dorelal
    var Dog = function() { var _instance = 'hello world'; return function() { console.log(this._instance); } } (); //note that it is self invoking function var l = new Dog(); //#> undefined In the above case I was expecting output of 'hello world'. Why this._instance is not accessing the the varible which should be accessible by virtue of closure. I tested this in FF and am getting undefined.

  • How to place some text over the DIV without breaking hover area of this DIV?

    - by Andr
    I'm total noob with CSS and it looks like hell =/ I have absolute positioned DIV and I handle mouse events over this DIV with JS like this: <div style='position: absolute; left: 0px; width:50px; height: 50px;' onmouseover='this.style.border="2px solid red"' onmouseout='this.style.border="1px solid black"'> </div> <div style='position: absolute;'>SOME TEXT</div> I need to place some text over this DIV and over the few same DIVs, but if I place any element over this DIV onMouseOut event is firing when mouse cursor switch to text. Tag with text can't be inside the DIV. Playing with z-index didn`t help. My browser is IE8.

  • onclick from an Object's button doesn't work

    - by 730
    I instantiate an object, with an argument which is a button. When the button of an instance is clicked, it should run a function, but it doesn't. In the full version of the code, Chrome gives this message in the console: "Uncaught TypeError: Cannot read property 'onclick' of undefined" HTML: <textarea id='txt' readonly rows='5' cols='40'></textarea> <button id='btn' type='button'>click</button> JS: var btn = document.getElementById('btn'); var txt = document.getElementById('txt'); var foo = new Foo(btn); function Foo(btn) { this.button = btn; } Foo.prototype.buy = function() { txt.value = 'Foo Bar'; }; Foo.button.onclick = function() { foo.buy(); }; Fiddle

  • scrollTop issue on constant moving div

    - by joe
    I have a FLASH object that I mouse over which in turn calls the following function to scroll a div. It works but due to the constant high speed scrolling it would throw up NULLS. This in turn caused IE to open a new page through my FLASH ActionScript 2.0 I found that by creating the SC variable and throwing in the condition "if it exists" keeps FLASH from causing IE to open a new page. However, it still creates an error behind the scenes of "Object Required". Although my application works I do not want load up memory with errors. Any thoughts? var SC; function pP(PT){ SC=document.getElementById('P'+PT).offsetTop; if(SC){document.getElementById('CBOX').scrollTop=SC;} }

  • jQuery reader() on downloaded content.

    - by David
    Hi all! jQuery.ready() allows us to wait for the construction of the webpage. Recently it has been added support to wait until CSS files are loaded. I would like to know if that feature can be used for downloaded content, because I fetch content via $.ajax() that holds CSS references and I would like to retrieve the content of the CSS before working with the retrieved content. Fetch with $.ajax() the html. -- Wait until all CSS is downloaded. Show to fetched content (already css'ed). Thank you very much for your help.

  • jquery next siblings

    - by Contra
    Hi stackoverflow! (first post!) Ive been trying to get this problem solved, but I cant seem to figure it out without some serious workarounds. if I have the following html code: <ul> <li class="parent"> headertext </li> <li> text </li> <li> text </li> <li> text </li> <li class="parent"> headertext </li> <li> text </li> <li> text </li> </ul> Now, how do I now just select the li's following the first parent (or second, for that matter)? Basically selecting an li with class=parent and the following siblings until it reaches another li with the parent class. I could restructure the list with nested lists, but I dont want to do that. Any suggestions?

  • Are function arguments stored in a closure?

    - by Nick Lowman
    I was reading this great article about closures here and the example below outputs 'item3 undefined' three times. I understand why it outputs 'item3' three times as the functions inside buildList() all use the same single closure but why can't it access the 'list' argument? Why is it undefined? Is it because the argument is passed in after the closure has been created? function buildList(list) { var result = []; for (var i = 0; i < list.length; i++) { var item = 'item' + list[i]; result.push( function() {console.log(item + ' ' + list[i])} ); } return result; } function testList() { var fnlist = buildList([1,2,3]); // using j only to help prevent confusion - could use i for (var j = 0; j < fnlist.length; j++) { fnlist[j](); } }

  • jQuery Nested Droppables

    - by John
    I have a nested set of jQuery droppables...one outer droppable that encompasses most of the page and an a set of nested inner droppables on the page. The functionality I want is: If a draggable is dropped outside of any of the inner droppables it should be accepted by the outer droppable. If a draggable is dropped onto any of the inner droppables it should NOT be accepted by the outer droppable, regardless of whether the inner droppable accepts the draggable. So that would be easy if I could guarantee 1+ inner droppables would accept the draggable, because the greedy attribute would make sure it would only get triggered once. Unfortunately the majority of the time the inner droppable will also reject the draggable, meaning the greedy option doesn't really help. Summary: The basic functionality is a set of valid/invalid inner droppables to accept the draggable, but when you toss the draggable outside any of the draggables it gets destroyed by the outer droppable. What's the best way of doing this?

  • How to match !x but not !!x in JS regex?

    - by mpeterson
    Given the following text: This is!!xa simple string!xpattern I would like to get a regexp that matches the !x that's between "string" and "pattern" but not !!xa that's between "is" and "a". This regexp is to be used inside a string split(). I have tried several combinations but I cannot get a regexp that meets my needs. Perhaps my expression is not so regular after all =) Thanks in advance!

    - by Jim
    I have a script that create a new div element. Then, I want to append the div to the body of the page using appendChild method. The script is look like this : var div = document.createElement('div'); div.id = 'newdiv'; document.body.appendChild(div); Unfortunately, the div also appended to the body of iframes. So, my question is, how to refer to the true body of the document, not including the body of the iframes? That way, the div just appended once, to the "true body" of the document. Thanks before, and sorry if my english is bad. :-D
