function changeYear(today)(holiday){
b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.
first line
c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.
second line
d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.
third line
e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.
I'm currently facing a weird issue with the onchange event. I have a web application where each blur event makes a call the webserver to store the value of the textfield. I only want to trigger that ajax call when something has changed, so i track the onchange event on each textfield to set a flag if something has changed.
The onchange event always fires to first time when i click outside of a textfield even if i didn't change anything in the field.
I narrowed it down to the following: A prefilled textfield always fires the onchange-event the first time you leave the textfield. An initially empty textfield does not fire the onchange event.
Sample code (IE 8 on Windows 7 computer):
script:
HTML:
I want to capture the event when the <ctrl> key is pressed.
View 3 Replies View RelatedI want an event to be triggered when I use left and right arrow buttons like this:
Code:
$(document).keypress(function(e){
if (e.keyCode == 39 && key_pressOK) {
e.preventDefault();
$("#next").trigger('click');
key_pressOK = 0;
}});
This works on firefox, but not chrome, haven't even bothered checking the other browsers since it didn't even work on chrome.
I have a code for the keydown event:
-when you press the UpArrow key the image moves up
-when you press the DownArrow key the image moves down.....and so on
But don't forget that this is under the keydown event...so when I keep pressing the UpArrow key the image moves up but when I release the key the image still moves up. I already put the code $('myImage').stop(); on my image on keyup event but this doesn't do anything. There is a code to clear my memory from pressed keys or something?

View 5 Replies View RelatedIve never heard of this being done, but currently ive got a div which sits in the center of my screen. The div is about 80% wdith so there is a 10% gap on the left and 10% gap on the right. However, I want the gap on the top and bottom of my div to be the same as my gap on the left and right.
I need to somehow capture the pixel value for the gap on the left and right, store it in a variable and then use this number in my css for the top and bottom gap.

So I was wondering instead of calling document.getElementById('theTest').innerHTML; multiple times is it possible to store this as a variable and then access this later? If I want to change it though Have to go document.getElementById('theTest').innerHTML = something: right?
Is it even worth it to do something like this or is document.getElementById('theTest').innerHTML fast enough?

I have been struggling with an AJAX issue for 2 days now and have finally started looking for some help. This is my first post on this forum but by the looks of it , it seems to be full of people who know what they are doing so I humbly ask your advice on this issue. I want to build a javascript function which can retrieve data from an SQL database by calling a php script. For this I use the script underneath. There is off course a php-part to this but the problem is not situated there since the script runs smoothly if I put the returned value (ajaxRequest.responseText) into an html-element like a <div> for instance.
If I don't do this however and just want to assign it to a javascript variable (like shown below : window.out_text = ajaxRequest.responseText) it will not show when I call document.write(window.out_text); EXCEPT WHEN THERE IS A DELAY. So If I put alerters in there to slow down the generation of the final html, it seems to be able to write the javascript variable to the screen. Is this a bug in the ajaxRequest.readyState? Or am I doing this wrong? And especially: How can I solve this. Someone else on this forum must surely have already ran into this problem?

View 4 Replies View RelatedI'm using this bit of jQ to add a class to two different elements based on the class of another (parent/grandparent, etc) element.
First, when there's no class at all in <div id="main-content">, the 'active' class is added to *all* the #nav-primary LIs, and also to *all* the #aux-left DIVs; how can I modify this so that in the absence of any class on #main-content, do nothing?
Second, how can I target only the first or second of multiple classes to store in the 'containerClass' variable, e.g., <div id="main-content" class="apples bananas">?

I tried creating a global function to calculate the distance between 2 points.
jQuery.distance(p1, p2){
var dx = p2.x - p1.x;
var dy = p2.y - p1.y;
return Math.sqrt(dx^2 + dy^2);
};
Somewhere else within my code, I declare a new variable in order to store the value returned by the distance function.
var distance = $.distance(particle1, particle2);
However this is not working.
I would like a function to be run whenever a variable is updated. I
have tried binding the onchange event to it, and it doesn't work. I
think I understand why, however, I would like to know if there is
anything that I can bind to my variable that will fire the specified
function whenever the value changes.
Is it possible to do this, or would I have to make a class for it?
