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?

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?

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?

Calculate While I Type

Jun 29, 2006

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.

Calculate Once New Value Is Typed In?

Apr 8, 2011

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.
