# Calculating Possible Routes Between Two Points

Oct 18, 2011

I am not a developer so not so familiar with javascript. Suppose I have a map with ten junctions and based on that map. I need to calculate all the possible routes between one junction to another. How do I represent the map in javascript and how do I code the function to calculate all the possible routes?

## Input That Points To Some Other Function?

Aug 16, 2009

Is it possible to have an input that points to some other function?
For example:
function someFunction() {
}function doAnotherFunction(doIt, otherFunction) {
if (doIt == true) {
otherFunction();
}}
<input type="button" value="test" onClick="doAnotherFunction(true, someFunction());">
Or would I need a switch statement and have all the various functions hardcoded?

## Google Maps + 5000 Points Too Much For JS?

Dec 22, 2009

I have a boss who wants to show 5000 points on a Google map. So far, only a fraction of this being displayed freezes the browser. I've been challenged to make this possible while still in the realm of the browser. Would the flash version of Google maps api be a better bet? Does flash provide a better framework for this kind of heavy usage?

## Get Actual Screen Size In Points Or Cm?

Nov 13, 2010

## Rounding Figure And Have Only 3 Digits After Decimal Points

Nov 8, 2009

Suppose I do (5 * 0.039) + 0.59, then the result is 0.7849999999999999 - but I want to round it upwards and should have only 3 digits after decimal point. I found out that using toFixed(3) will get it to be 0.785, but the problem is that it add x.x00 for some numbers where there aren't much decimal numbers. Is there a way I can remove the 0's?

## Vector And Magnitude - Two Points P1(30, 20) And P2(30, 221) And The Parametric Equation

Nov 22, 2011

I can't figure out this math problem. I have two points p1(30, 20) and p2(30, 221) and the parametric equation of the vector is (x-30)/(30-30)=(y-20)/(20-221)=t x=30, y=20-201*t

I'm thinking t is the magnitude or the distance. For a point P which is 10 pixels away from p1 on the vector, x=30, y=20-201*-10 (should be around -0.85) which is not the right P i'm looking for. Where am i doing wrong?

## Estimate To Viewers Based On Their Input - Decimal Points

Jan 22, 2010

I am trying to develop a form that can give an estimate to viewers based on their input and I'm having a problem with decimal points.

## Split On Decimal Code Points Or Equivalent Format?

May 10, 2010

I am in the process of using the split function for splitting strings into an array. The problem I am dealing with is how to do this with local language. Not all languages us the space " " delimiter between words to write a phrase or sentence.

I have a list of all of delimiters for english, japanese, chinese, korean in Decimal Code Point format. For example, the decimal code point equivalent for " " is 32. Is it possible to use the javascript split function with decimal code points? If not, how can I reformat them into a format that js would understand?

## Calculating Shipping With If/else And Function?

Sep 21, 2009

I am having difficulty getting the following assignment to run properly:Many companies charge a shipping and handling charge for purchases. Create a Web page that allows a user to enter a purchase price into a text box and includes a JavaScript function that calculates shipping and handling. Add functionality to the script that adds a minimum shipping and handling charge of \$1.50 for any purchase that is less than or equal to \$25.00.For any orders over \$25.00, add 10% to the total purchase price for shipping and handling,but do not include the \$1.50 minmum shipping and handling charge. The formula for calculating a percentage is price * percent / 100. For example, the formula for calculating 10% of a \$50.00 purchase price is 50 * 10 / 100, which results in a shipping and handling charge of \$5.00. After you determine the total cost of the order (purchase plus shipping and handling), display it in an alert dialog box. Save the document as CalcShipping.html.This is what I have after working on it round and round for 4 hours yesterday:
