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 am trying to create a new global variable in a function with a custom name. I need something like this:
function newVariable(name){
createVariableWithName(name);
}
I have a function that returns an array object
like -
IsWithinGeofence(point)
{
....
...
if(some condition == true)
{
return PointsOfInterest[i];
}}
Here PointsOfInterest[i].lat = 56.45556, PointsOfInterest[i].lng = -2.5413 and i = 2;

I am calling a PHP script and trying to store the results to a Global Variable for use in later functions. But It doesn't seem to be saving the results to the variable. I have found, that within the ajax success call it will display the proper information. Outside of the AJAX success (whether in the function or outside of it) the variable is listed as undeclared.

I have a .js file that receives a value from an html page. I'd like this
value to be a global variable that all functions in the .js file can use. I
have tried just declaring a var at the top of my .js file, but when the
value comes into the function and gets assigned to that variable, it is not
global.
I would like to store a variable then call it back later. I have a variable on line 198
www = ''+this._ad.clickUrl+'';
And on line 321 I try
document.write(www);
I've tried so many different options, just won't work. I have even tried to call document.write(window.www);

The purpose behind this is creating a form that will work with an existing database that would normally have a text area with lots of information. I am trying to turn it into a checklist that I can run from a mobile device. The global variables woudl be used to fill in a hidden text area that would then be passed on to the database upon submission. I am trying to keep the code as compact as possible.

I am using jQuery 1.4.2 and I am trying to carry over the global variable totaltabs into my JSON callback function. The code seems to work properly, however, in my loadJSON function after the callback function loads the data, my totaltabs variable will not increment.

I am simply trying to use a global variable in javascript, but can only access the variable on the second call. I can't find anything that relates to this through my searches.

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.

Unfortunately, isValid never changes from the initial "true". I know that $.post is working correctly because #msg_code reflects the corresponding message.
