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?

View 1 Replies View RelatedIs it possible to have an input that points to some other function?
For example:
function someFunction() {
alert('It worked.');
}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?
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?

I am trying to wrap a text selection with BBCode. I have it working, but there is one final part I need help with.[code]...
So, the last thing I need to do (the whole point of this post)... how do I MOVE the range start and end points so that only the selection is selected and NOT the whole thing?
I have an input in the form, where i have to do the following validations.
1) see if it is a number
2) allow digit grouping wither like 00,00,000(Asia format) or 000,000,000 (us format)
3) allow 2 decimal points 000,000.00
4) if the money does not conform to this format return false
I need to know how to get the actual screen size in points or cms, not in pixels. The javascript functions give me the pixels, but I need to know how many points or centimeters that is regardless if it comes from a browser or a device like an ipad or iphone. Does anyone know the code to calculate this?
View 8 Replies View RelatedSuppose 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?
View 9 Replies View RelatedI 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?

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. I couldn't find a very good free script online so I've done some work with this one [URL] When you enter 10 in the input box, it calculate 10*19.99, giving 199.9, but I want it to show 199.90. I've tried adding toFixed(2) in there, but I'm not able to get that to work.
View 6 Replies View RelatedI 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?

In PS you press CTRL+T on new layer. 9 handles appears an then you can stretch/rotate/move that layer. Looking just for that stretch & rotate functionality with dotted/dashed retangle outline. That is, there should be 8 handles on rectangle boundarys and then rectangle should be rotated & stretched via those points. & moved via nineth center point.
View 5 Replies View RelatedI want to add onto my ebay auction a calculation which would show the unit price of a box of 5 electrical sockets.
So say it is currently on auction at £5.62 and I charge £1.99 Postage & packing thats a total of £7.61 with a unit price of £1.52. Then £1.52 is the figure I want to output and show on screen.
I'm just starting out in JS and would like to know how to solve this.
I have an HTML form with 3 checkboxes, like a would-be order form. For example, on checkbox 1, the product is a toy car that costs $5.00, second box is a cigar cutter for $50, etc. I to have a button that when clicked, enters the total price (no taxes or subtotals) into a textbox field below in the same page.
I believe that this has been answered somewhere but I cannot find it. I have 51 textboxes on page. In 50 I can enter value. 51st should tell me what is average of entered numbers.
As user types I want script to iterate trough form count and sum non-empty fields and than divides this two numbers.I need to sum values from fields that have value (not emty fields) and to divide this number by number of non empty fields. This should occur on every change in any of those 50 textboxes so to have live preview of average.
I'm really new to JS and I don't know even how to sum these numbers.
I have some data thats in a number, lets say 5455

I'm working on creating a custom calculator to determine the amount of money / credits users may earn from referrals. I've tested onChange, and it will work only when I have changed to a new field or clicked off that field. How do I make this calculate live?
So if the current value is 5 and I change it to 6, it will automatically recalculate the new value.
You can see what I'm working on here:

Note: The one I'm testing is the 1st Level field. For now i'm just having it display the date.
