## JQuery :: Calculate Number Of Months Between Date Ranges?

Aug 3, 2010

For a project that would be too hard to explain, I am working with date ranges. There is a begin date and an end date. With those two variables, I need a function to calculate the number of months between both dates. To be more precise, I need a count of all unique month names in the dates (or month numbers if that is easier) where the range includes the beginning date, the end date, and all dates in between. So I am not looking for full months or an approximation. If only, say, one day of a given month is included in the date range, that adds a month. Also the range can span several years, january 2010 and january 2011 need to count for two different months.

## How To Find / Calculate Average Number

Feb 1, 2010

I need to find the average number in javascript. It is the only bit of javascript that I have to do in the course but it carries a high mark of which I cannot afford to lose. Any way the question is : "Write code to calculate the average height and write it out in the browser window"

<SCRIPT LANGUAGE = "JavaScript">
//Experimental results of Table 1 stored in arrays.
var Height = [15,16,17,18,19];
var Number = [2,1,6,4,2];

//Part (ii).
//Write code to declare and initialise new array to represent the third row of the table.
var avg = new Array(5)
var avg = ["60","80","187","180","114"] ;
avg = "60";
avg = "80";
avg = "187";
avg = "180";
avg = "114";
//Part (iv).
//Write code to calculate the average height and write it out in the browser window.
avg = 0;
for (var count = 1; count <= 5; count = count + 1)
Array.average = function(){
var avg = 0;
for(var a = 0; a < this.length; a++){
avg += this[a];
} return avg / this.length;
};

document.write('average height is ' +avg + '<br>');

## Getting Dynamic Rows Inputs To Multiply 'onchange' Of The Value In The Input In Each Row?

Feb 4, 2010

getting dynamic rows inputs to multiply 'onchange' of the value in the input in each row. It works in the first row inserted no matter what rowindex that row is moved to. All following rows only accept the initial input value and never change the 'cost' innerHTML of the colRow[i]. I figure I need a parentNode.parentNode syntax to make this function work in all rows.

Every thing is Client-side javascript and all rows are inserted to 'cartbody.insertRow'. 'qtymultiply()' Function As is:

Code:

function qtymultiply(){
var cartitems=document.getElementsByClassName('itemrow');
var colRows=cartitems;

## JQuery :: Prevent Action To Be Executed Before It Starts?

Apr 27, 2010

I am building a navigation which animates width on mouseover and revert it on mouseleave. That navigation also supports keypress/keydown actions, so it behaves like you hover with the mouse and additionally opens the submenu too. My problem is, when using the keydown (C) function, the menu opens up perfectly but when I mouseover then, it fires the 1. function and behaves like it should, it closes. I tried to stop that when just using keydown, but somehow I am stuck with it. Here comes the code:
