## JQuery :: Create A Global Function And Store The Return Value In A Variable?

May 15, 2011

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.

## ChangeYear - GetFullYear - SetFullYear Functions - Extract The 4-digit Value From The Today Variable And Store The Value In A Variable Named Year

Oct 13, 2009

a.) specify two parameters for the changeYear function: today and holiday.

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.

## AJAX :: Store Retrieved Value In Variable?

Jul 30, 2011

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?

## JQuery :: Store In Variable Only First / Only Second Of Element's Multiple Classes

Apr 22, 2010

I'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?
