  • Can I void all JavaScript calls to $

    - by alex
    I need some scripts inside an existing site's scripts.js. This site has been online for ages, and I can not touch the scripts file. I am including it standardly in another page. There are numerous jQuery calls in the scripts file. The place I include it does not have jQuery. I want to void all $() type things. I tried this... $ = function() { }; before I included scripts.js and it didn't seem to work. I am still getting errors like $(document) is undefined Is there a way to void all these jQuery calls? Thanks

  • Javascript: how to tell if a node object has been inserted into a document yet

    - by thomasrutter
    I'd like to be able to identify whether a given DOM node has been inserted into a document, or part of one, yet, or whether it is fresh out of document.createElement() or similar and has not been placed anywhere. In most browsers just checking the parentNode works. if (!node.parentNode) { // this node is not part of a larger document } However, in Internet Explorer it appears that new elements, even right after they've been created with document.createElement() already have a parentNode object (of type DispHTMLDocument??). Any other nice cross-browser and reliable way?

  • JavaScript try/catch: errors or exceptions?

    - by Josh
    OK. I may be splitting hairs here, but my code isn't consistent and I'd like to make it so. But before I do, I want to make sure I'm going the right way. In practice this doesn't matter, but this has been bothering me for a while so I figured I'd ask my peers... Every time I use a try... catch statement, in the catch block I always log a message to my internal console. However my log messages are not consistent. They either look like: catch(err) { DFTools.console.log("someMethod caught an error: ",err.message); ... or: catch(ex) { DFTools.console.log("someMethod caught an exception: ",ex.message); ... Obviously the code functions properly either way but it's starting to bother me that I sometimes refer to "errors" and sometimes to "exceptions". Like I said, maybe I'm splitting hairs but which is the proper terminology? "Exception", or "Error"?

  • Pure HTML + JavaScript client side templating

    - by Dev er dev
    I want to have achieve something similar to Java Tiles framework using only client side technologies (no server side includes). I would like to have one page, eg layout.html which will contain layout definition. Content placeholder in that page would be empty #content div tag. I would like to have different content injected on that page based on url. Something like layout.html?content=main or layout.html?content=edit will display page with content replaced with main.html or edit.html. The goal is to avoid duplicating code, even for layout, and to compose pages without server-side templating. What approach would you suggest? EDIT: I don't need a full templating library, just a way to compose a pages, similar for what tiles do.

  • JavaScript Loop and wait for function

    - by Fluidbyte
    I have a simple single-dimension array, let's say: fruits = ["apples","bananas","oranges","peaches","plums"]; I can loop thru with with $.each() function: $.each(fruits, function(index, fruit) { showFruit(fruit); }); but I'm calling to another function which I need to finish before moving on to the next item. So, if I have a function like this: function showFruit(fruit){ $.getScript('some/script.js',function(){ // Do stuff }) } What's the best way to make sure the previous fruit has been appended before moving on?

  • complex web forms and javascript

    - by Casey
    I need to create a few data heavy complicated forms. Currently, the information is being entered into a spread sheet, but the users will need to enter the information into the online form where it will be saved to a database. The problem is that the business users currently using the spread sheet aren't going to want to use the online application if it isn't as easy as entering the information into the spread sheet. This is further complicated in that the information they are entering into the spread sheet is represented by three different DB tables where one "object" is composed of two of the others. I would prefer to not have them have to go through multiple forms. Some of what I have been thinking is: Use of auto complete where possible Hiding/removing form fields dynamically possible wizard style page flow?? I've been googling for other data heavy web forms but can't seem to really find any good examples. I am familiar with jQuery and prototypejs and have also tried googling for frameworks designed for data heavy applications but didn't come up with anything. Any thoughts? Thanks.

  • how to get the value from a CSS class object in javascript

    - by amit
    I have to select an <a> element from the given class of objects. when i click on the anchor tag in the showcase_URL class, i want the jquery function to get the value from <a> tag. How can this be done? I cannot make this an id as I am running a while loop to construct all the elements in php. there would be multiple objects of this class. there is no definite selector through which I can get the value of the anchor tag. Help would be much appreciated. echo '<div id="content">'; echo '<div class="showcase_data">'; echo '<div class="showcase_HEAD">'.$row->title.'</div>'; echo '<div class="showcase_TYPE">'.$row->type.'</div>'; echo '<div class="showcase_date">&nbsp;&nbsp;'.$row->date.'</div>'; echo '<div class="showcase_THUMB" style="float: left;" ></div>'; echo '<div class="showcase_TEXT">'.$row->details.'</div><br/>'; echo '<div class="showcase_URL"><a class="purl" value='.$row->num.'href="'.$row->url.'">PROJECT URL</a></div>'; echo '</div>'; echo '</div>';

  • Is the javaScript not part of the DOM?

    - by DKinzer
    Why is it that scripts can still function even after the code used to create them is removed from the DOM? I ran into a situation where I wanted to prevent a broken script from running (@see my post). In my attempt to come up with a solution I wrote an extension with the following line (just to see what would happen). //doc is passed here because this script is running as a firefox extension outside //of the document context. $('script', doc).remove(); I assumed that this would remove all the scripts from the DOM, which it did, and that therefore no scripts would run on the page, which is not the case. I would love to know more about what's behind this behavior.

So i want to have a timer that is started on key up, if the timer reaches 800ms then the ajax is called, if a new keyup event occurs the timer is restarted how would i do this?

  • Find consecutive "//" in regex in JavaScript

    - by iOnline247
    I gave it a college try, but I'm stumped. I'm trying to find consecutive slashes within a string. The rest of the regex works great, but the last part I can't quite get. Here's what I have: val.match( /^[\/]|[~"#%&*:<>?\\{|}]|[\/|.]$/ ) and finding this thread, I decided to update my code to no avail: RegEx to find two or more consecutive chars val.match( /^[\/]|[\/]{2,}|[~"#%&*:<>?\\{|}]|[\/|.]$/ ) What do I need to get this thing going?

  • Javascript onclick stops working, multiple dynamically created divs.

    - by Patrick
    I have run into a strange problem, i am creating a lot of dynamically divs. And i recently found out that some of my divs doesn't fire the onclick event? All the divs are created using the same template, so why are some not working? Most of the time, its the 4-5 from the bottom. If you click on one of the others and then try again, you might get one of those to trigger. But only sporadically. Code to create the divs: GameField.prototype.InitField = function(fieldNumber) { var newField = document.createElement("div"); if (fieldNumber == 0 || fieldNumber == 6 || fieldNumber == 8 || fieldNumber == 17) newField.className = 'gameCellSmall borderFull gameText gameTextAlign'; else newField.className = 'gameCellSmall borderWithoutTop gameText gameTextAlign'; var instance = this; if (fieldNumber == 6 || fieldNumber == 7 || fieldNumber == 17) { } else newField.onclick = function() { instance.DivClick(fieldNumber); return false; } this.fields[fieldNumber] = newField; this.score[fieldNumber] = 0; return newField; } I added the return false to the click function, but it still behaves strangely. Why are some not triggering? I create around 18 divs / player. But it happens even if i just create one player. Do i perhaps need to cancel the event once i am done with it? (Like the return false; is trying to do)

  • Selecting pictures with Jquery and Javascript

    - by Axschech
    I'm testing out a layout on a website using 3 pictures here: Schechterbusiness.info the left button works, making it go through the pictures. But I can't figure out how to get the right button to work, which is supposed to scroll through the other way. I know there's probably a way to do it with arrays but I can't wrap my brain around it. Halp! Code to scroll through pictures: $('#fryLink').click(function() { $('#hide').hide(); $('#img').hide(); count++; if(count == 1) { $('#img').attr("src","images/fry.png"); } else if(count == 2) { $('#img').attr("src","images/bender.png"); } else if(count == 3) { $('#img').attr("src","images/zoidberg.png"); } $('#img').show("fade"); if(count > 2) { count = 0; }

  • Loading html dynamically using Javascript and PHP

    - by Vafello
    I have the following code: <?php if ($x == 1){ ?> <b>Some html...</b> <?php } else if ($x==2){ ?> <b> Other html...</b> <?php } ?> Now I would like to have two links below (a href) and somehow pass the variable $x (so Link1 passes x=1 and Link2 passes x=2) in order to load the relevant bit of code from if statement. I know I can pass $x using form and then test its value and load required bit of code, but I would like to do it smoothly, without reloading the page. I think that JQuery could help it, but I have no idea how to do it. Any ideas greatly appreciated.

    - by Michael Robinson
    I got a problem. I have a image upload script that runs on a popup up when you select "upload button", after it is complete instead of closing it stays in the uploader.html window. I need it to close and go to a new page. Here is some of the xml that the script uses, can I change the "urlOnUploadSucess" line to close the popup and load a new page on the original page I came from? .....<upload preload="Preloading images:" upload="Uploading images to server:" prepare="Processing and image compression:" of="of" cancel="Cancel" start="Start" warning_empty_required_field="Warning! One of the required fields is empty!" confirm="Will be uploaded:"/> <urls urlToUpload="upload.php?" urlOnUploadSuccess="http://www.baublet.com/purchase.html" urlOnUploadFail="http://www.baublet.com/tryagain.html" urlUpdateFlashPlayer="http://www.baublet.com/flashalternative.html" useMessageBoxesAfterUpload="false" messageOnUploadSuccess="Images were successfully uploaded!" messageOnUploadFail="Error!
