thanks !and one simple thing to ask tan 90(degree)is undefined but my clac shows a number which is quite big.16331778728383844 .i coverted it to degree.but its not showing undefined
function trig(el,oprtr){ var m=document.getElementById(el); var p=(m.value)*( Math.PI/180); var v=Math.ceil(oprtr(p)); m.value=v;} -
@
Hadienactually some trig function values are undefined.i need my calculator to show that.some trig function is not working properly in javascript.say tan 45 supposed to be "1". its showing 1.6..... somehow .confiused!!!! :|

why had to use an extra parenthesis and +0 with it?

i have made a calculator.where i want to put sin, cos and tan button .and thats not the problem.i want a single function to emplement sin ,tan ,cos without creating three different function.
whole code is here...

the "+" sign is not adding in the div with others.why this happens.other numbers works fine but symbols don't acting like them

thanks
-
can a setTimeout function be looped???
-
its clear to me now .thanks a lot!!!
-
actually how i see the function is
1)onCLick show will start
2)s=its_prop() will be called;
3)as i set setTimeout() in a way that it will re-execute its_prop() until 1==10 ;
4)it will then return true after its_prop() executed 10 times.
it should be like that,isn't it?still confused
-
will you please explain it again?? it is not perfectly clear to me.i don't see any wrong in my code.but can't catch the problem

i want to show a div onClick over a button.and stay there a for a little moment then disappear again.codes seems fine but not working...

what does this gives us?
parent_form.elements.length
will it work for any html element
lyk if i have a div and it has other elements in it lyk <a>,<img>etc ,will it gives me no.of elements inside that particular div?
-
thanks!!!
-
you probablly didn't understand my question.i wanted to know in an if condition can i use a function is executed before or not as a condition and i want it to check inside the paranthesis
like
if(----in here----)

i have made two radio buttons.which will show a perticular text in box when clicked.problem is once it's been checked i want to uncheck it if clicked again and when clicked another radio button as well.how can i do that stuff
<!doctype html><html><head><meta charset="utf-8"><title>Untitled Document</title><style>#forms{ width:30px; height:20px; border:1px solid black;}</style></head><body><div id="forms"></div><input type="radio" value="player1" onClick="show('forms',1);"><input type="radio" value="player2" onClick="show('forms',2);"><script>function show(el,n){ var m=document.getElementById(el); m.innerHTML="player"+n;}</script></body></html> -
i think a function can contain another function which will be called during execution
so, i think it's possible .or can't ? feeling confused
function show(){[...]whatever();}i have not encountered this type of code yet
onClick="show(); whatever();"
it would be helpful if you describe the topics to make it clear to me
-
title will be "check a fucntion executed or not!"
say i have a html element...
<a onClick="show();" >some text</a>
after i clecked on the link the function show( ) will be executed.
function show(){---------------------------;_________________;}in my script tag i have a if condition which i want to execute depending on show() is executed or not.if show() is executed if statement will execute and if not if will not be executed.how can i test that
is it correct???i think not!!!
<script>if(show()){ ---------------------------;------------------------------;} -
yes of course..got the idea of using array to store values from your post...thanks again
-

still slow.now i understand its my pc/browser's problem
.i have a question thouge.why you used false as argument instead of true in cloneNode???
-
i have tried that one too.not worked either..
.
how can i increase by poing
in JavaScript
Posted
in my previous post i posted a problem about my javascript calculator .in my calculator in made a log button which base is 10;it shows a perfect integer result.say it gives accurately 2 if i want to find the log of 100.but if i want log of 104 it doesn't work;how can i solve that
function log10(el){ var m=document.getElementById(el); for(;{ var d=Math.pow(10,i); if(d==m.value){ m.value=i; i=0; break; } i++; }}
