Image Complete Property Prematurely True?

Apr 2, 2007

I've been playing around with some means of testing image loading, and noticing that the "complete" property seems to default to true. Trying the following in the squarefree javascript shell:

I = new Image();
I.complete

yields "true".

Seems a bit odd -- obviously there's no src given yet, so is it really complete? Is this behavior defined that way on purpose? If so, what's the justification?

What To Use Instead - Complete Property In FF - Gallery With Image Loader

Apr 27, 2010

I want to make a gallery with image loader. When image placed in JavaScript Image object finishes loading, the script includes it into HTML code and performs jQuery fadeIn effect on it.

The '.complete' property of the Java Script 'Image' object is perfect for this purpose(recognizing when image has finished loading) but the only problem is that Mozilla Firefox doesn't recognize this property and in this browser it's always true(always loaded) even if it's not. The script works perfectly in other browsers.

Does someone of you know what is the other way of recognizing whether the image finished loading or not?

JQuery :: IE9 Does Not Properly Support The Complete Property Of An Image?

Mar 16, 2011

Don't really think this is related to jQuery but I thought I would post it here in case someone else was having a problem. I have a plug-in I made that uses an image preloader involving the jquery .load() function. Once all images are preloaded, a function is fired to initiate the plugin.bIf the image is already loaded in the cache, the script checks the .complete property of the image to see if it is true, then manually fires the callback function for the load script. Here is the code:

JQuery :: Loop Ends Prematurely With Each()?

Oct 14, 2011

I think there is something simple I'm missing, but I'm unsure how to fix at this point. I have a sidebar with a bunch of unordered lists. Each sidebar li item may or may not have a class assigned to it. I need to scan every list item for any with a special class, say: listClass1, listClass2, listClass3. Ignore all others.

Change Image On .gif Complete?

Feb 12, 2010

i'm trying to get to grips with Javascript for a Uni project, on this one i'm trying to show an image then replace that image with a .gif animation. Once the .gif has finished its animation once i want to replace it with a different image to the first.

the code I've come up with is running on a simple timer and loops endlessly, if anyone has any pointers that could help me or just tell me how to get my desired effect in a way i can understand then hopefully i can base my learning Javascript around that.

here is my code so far!

<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script language="Javascript">

Hide / Show Table - For Loop Ends Prematurely

May 18, 2011

The functions hide/show tables within a page, and update a button by the table title accordingly. The number of tables on the page is dynamic (php generated based on an SQL query), so the Expand/Collapse all buttons are generated last, and pass the table count to the functions in variable x. I have confirmed that the number passed in x is correct for the number of tables, and that all of the tables' IDs are correct in the generated HTML. The problem is that no matter what is passed in x (currently over 300), the loop ends at 27.

function expand_all(x){
var i=1
for(i = 1; i <= x; i++){
document.getElementById('tbl' + i).style.display = "block";
document.getElementById('lnk' + i).value = "[ - ]";
}}// end expand_all
function shrink_all(x){
var i=1
for(i = 1; i <= x; i++){
document.getElementById('tbl' + i).style.display = "none";
document.getElementById('lnk' + i).value = "[ + ]";
}}// end shrink_all

To confirm the values, I changed
document.getElementById('lnk' + i).value = "[ - ]";
to
document.getElementById('lnk' + i).value = "[ - ] " + i + " of " + x;
In both functions, I got incrementing values for i from 1 to 27. X consistently was 343.

JQuery :: Delay Code Execution Until Image Preloader Is Complete?

Sep 4, 2011

I'm trying to build an image gallery and I want to shrink all the images a bit to allow for enlarging them on mouseover. I have it working fine locally, but when deployed to my server it doesn't work because the image files are still loading as the javascript executes. What I wind up with is the js using the image's alt tag's text size as the image size, which then gets resized to create a squashed image. What I want to do is preload all the thumbnail images before the the function to resize them gets called so the resize function has the proper dimensions of the images to do the transformation on. I'm using the jQuery.Preload plugin for my preloading functionality.

$(document).ready(function(){

[Code]...

My expectation of this code is that the enable_anim_resize() function will not be called until all the images are loaded, but I don't see any difference in this execution than if I just sequentially put in my resize code after the preload line and didn't use the onFinished callback for the preload method (example below:) $(document).ready(function(){ From my understanding of the documentation and examples of the preload plugin, the enable_anim_resize() function shouldn't be called until all images on the page are loaded, at which point the proper dimensions of these images should be available for correct resizing. Can anyone clue me in on what I'm missing here?

Image Rollover Fails Complete Unless First Function And Loop Are Exited

Apr 11, 2011

Code:

If I use the return keyword to exit the function/loop after they set up the first image rollover, it works perfectly on the first image. However, if I comment out the keyword, theId, which is the variable that contains the id of each respective image (which is the same id of the containing link with "1" added to the end) becomes "undefined" (as my JavaScript console says), and thus none of the images work as they're supposed to work. Not even the first one.

One Grid Displays Numbers, True Or False And Yes Or No, And The Other Grid Displays Letters, True, False, Yes And No?

Feb 15, 2012

I have two grids, they both display buttons. One grid displays numbers, true or false and yes or no, and the other grid displays letters, true, false, yes and no.

The second grid is not displayed in the code (used css to not display second grid buttons (.answerBtns)) Now using the getButtons() function, if the user selects button "1" in first grid (the grid which you have to open using (Open Grid) link, then it should display button "A" in second grid, if user selects button "2" in first grid, then it should displays buttons "A" and "B" in second grid, if "3" then display "A", "B" and "C" and so on.

Now except using if statements and stating which buttons should be displayed and not displayed depending on the button chosen in first grid, is there a more efficent way of coding this so that the display of buttons in second grid depends on what is selected in the first grid?

If it is using an array can somebody show a sample of this in their answer. You can just do it for one example and then I should be able to use that to fill it for the other buttons.

Disable=true

Feb 27, 2007

I have a perl cgi form that has a popup_list. Based on a value that
is coming in from a database query, I want to either
1) display the value (from the databse) and let the user change it;
OR
2) display the value (from the database), but NOT let the user change
it.
I tried using javascript to disable the popup list, and that works,
except the form "loses" the value of the entry in the popup list.

Maybe "disable" is not the correct property I want to use. If that is
the case, what is it?

Not Submitting When Validation Is True

Jul 21, 2009

I've setup a form on my website and added a simple validation script to check a few of the fields. After all the validations are done I want the submit button to process two other functions that will handle the submission of the form.

The problem is that if the validation returns true the script just stops and doesn't run the other two functions.

Here is my validation script:

Then on my submit button I have:

Return True And SetTimeout?

Got a timing issue with sending a URI string out to a server side script right before a client side form validation process returns true..The problem is that the return true gets called to quickly for the submission of the URI string to be completed.So my question is, might there be a way to mix a return and a setTimeout?

Creating True Copies (of Objects) In JS (possible?)

Jul 20, 2005

Lets say I have this array:

a1 = [1,"2",new Array(2.5,3,3.5),4];

And I apply slice(0) on it, to create a copy:

a2 = a1.slice(0);

But this isn't a true copy. If I go a1[2][1] = 42, and then
alert(a2[2][1]) I will see 42 there too. I'm doubting, but I was
wondering if there is a general solution to this problem?

JQuery :: Contains('text') Return Is Always True?

Feb 12, 2011

I have a question concerning :contains(). I use it in the following manner:

if($("div:contains('Built From')", $(itemProps)))
{
//Do stuff.
}

itemProps is DOM Element. It has a a div inside it which class is always something else however that div has either "Built From" or "Builds Into" as a text. Inside itemProps there is no other div with those words. I want to know which of those texts the div within itemProps contains. However this bit of code seems to always return true. Some goes for when I use the text "Builds Into". Even when the text is not in the div.

JQuery :: How To Access True (This) Of Object

Jul 14, 2009

If "this" inside of a sortable "receive" function refers to the receiving object, How do I access the object to which the receive function belongs?

Example:
// Function that takes a JQ object and makes it sortable.
// We assign the "SortableRecieve" method to the receive event
MyObject.prototype.MakeSortable = function(JQOBJ){
JQOBJ.sortable({
receive: this.SortableRecieve
});}

MyObject.prototype.DoSomething = function(){
// Does something important
}
// The actual function that gets called when the receive event occurs
MyObject.prototype.SortableRecieve = function(event, ui){
// This function call won't work, because "this"
// doesn't point to the right thing!
this.DoSomething();
}
So how can I access the "True" this that refers to the object?
