JavaScript - Onclick With 2 Functions

Hi,

I have written a number of functions designed to return frequency data on 1000 randomly chosen numbers using different math functions for the rounding. I would like to include all of these functions within the wrapper of another function so that only one call is needed to get returns from all of the 'inner' functions. However, while each of the functions works in isolation, the moment I wrap them in another function they stop working.

The following code is one of the functions 'frequencyWrapperOne' that has been wrapped in the function 'testWrapper'. A call to testWrapper does nothing. Can anyone see what I'm doing wrong?

Code:

function testWrapper()
{

function frequencyWrapperOne()
{
	var numberArrayOne = new Array(0,0,0);
	for (var i = 0; i < 1000; i = i + 1)
	{
		var chosenNumber = Math.floor(Math.random() * 3); 
		if (chosenNumber == 0)
		{
			numberArrayOne[0] = numberArrayOne[0] + 1;
		}
			if (chosenNumber == 1)
			{
				numberArrayOne[1] = numberArrayOne[1] + 1;
			}
				if (chosenNumber == 2)
				{
					numberArrayOne[2] = numberArrayOne[2] + 1;
				}
					
	}		
	return window.alert(numberArrayOne.join(','));
	
}
}	
testWrapper();

Thanks.

I'm currently working on a project and I am doing a bunch of image switching.

I'm having a problem with the following...

I have seven medium image objects and one small one. One is at the top and the other 7 are below. When one of the 7 is clicked, it then becomes the one up top and the one up top then takes the place of the image clicked. This needs to be able to happen no matter which of the seven i click.

Also when you click one of the seven it runs a script to change 9 other images in the center of the page. this isnt too important because i have it working already.

What i have is, each of the seven images run their function that changes the 9 center images and then it runs another function.

What i need is for that function to determine which company for example(shaws, lowes, target) the top image belongs to and replace the image that was clicked with the top one. But i also need to replace the NAME="" and ONCLICK="function()" with the proper ones for the original company up top.

Please if you can understand what im trying to do let me know, if you need further clarification i can do so. i can draw a picture of what im trying to do or the layout if needed but i cant necessarily show anyone the project due to a non-disclosure.

Is there a way to activate a function from another function? It has to be in the script tag, it can't be in the HTML section. Can I use something similar to this following code? If not, can anyone give me some help? I have tried to do it various ways, and have looked it up a few times, but to no avail. Can I use something similar to this following code? If not, can anyone give me some help?

if (condition)
{activate functionname();}

Any help I can get would be appreciated. Thanks a lot to anyone who can help.

Ok here is what I have so far, my ending part of my Call Function I think is ok.

for my main function. I think I misplaced the { and }

I will show you all the codes I have

for my main function

this is what I have


I think I did misplace something but I can not pin point where that one small things should be


Code:

unction showResults(race,name,party,votes)
	{ 					// script element to display the results of a particular race
var totalV = totalVotes(votes);
document.write("<h2>" + race + "</h2>");
document.write("<table cellspacing='0'>");
document.write("<tr>");
document.write("<th>Candidate</th>");
document.write("<th class ='num'>Votes</th>");
document.write("<th class='num'>%</th>");
document.write("</tr>");
	}
	
	
for (var i=0; i < name.length; i++)
{
document.write("<tr>");
document.write("<td>" name[i] + "(" + party[i] + ")</td>");
document.write("td class='num'>" + votes[i] + "</td>");
 
var percent=calcPercent(votes[i], totalV)
 
document.write("<td class='num'>(" + percent +"%)</td>");
 
createBar(party[i],percent)
document.write("</tr>");
}
document.write("</table>");
}
</script>

Just wondering if i misplaced any ; or { or } anywhere suggestions?


Here is my call function
Code:

<script type="text/javascript">
	
showResults(race[0],name1,party1,votes1);
showResults(race[1],name2,party2,votes2);
showResults(race[2],name3,party3,votes3);
showResults(race[3],name4,party4,votes4);
showResults(race[4],name5,party5,votes5);
  
</script>

I been going over this, I can not seem to figure out what { i might be missing?
Thanks

Is it possible disable an onclick after clicking it and then enable it from another onclick by id

Code:

<img id="one" href="images/homepage/sliders/bonus_button.jpg" style="position:relative; top:30px; left:50px; height:30px; width:70px; float:left;">

This code runs when it is clicked:

Code:

$("#one").click(function() {
			
				runEffectB();
			
			
			
			return false;
		});

What I would like to happen is for either runEffectB() to not run if it was just run or to disable the #one.click once it has run.
I am assuming I will be able to re-enable it from another onclick running a similar function.
This is jquery and jquery ui if that helps.
Any ideas much appreciated.

I would really like to thank the guys that have been helping me. I think my brain would have exploded otherwize. Some of the problems have been simple misspellings, but when you have been staring at the same thing for hours it can sorta slip by.

HOPEFULLY this will be the last thing that I need some help with.

Bascially Im not sure if Im using the function command properly. When Submit Details is click it should validate the form and then when Calculate is pressed calculate the form (obviously).

I think maybe my var Array table is wrong? And the way the functions are set out doesnt seem it sit right.

Code:

 <script type="text/javascript">
				
				var element;
				var itemArray = new Array();
				itemArray [0] = "Bike"		//not sure if these are properly writen?//
				itemArray [1] = "TV"
				itemArray [2] = "iPod"
				itemArray [3] = "Car"
				var flag="OK";
				var count = 0
				
				document.write ("<form name='myform'><br><table>");
				while (count <= 3)
					{
					if (count < 3)
						{
						document.write ("<tr><td><value>Enter money from " + itemArray [count] + " sale.</td><td><input type='text' name=" + itemArray [count] + "></td></tr>");
						count++
						}
					else
						{
						document.write ("<tr><td><value>Enter the price of " + itemArray [count] + ".</td><td><input type='text' name=" + itemArray [count] + "></td></tr>");
						document.write ("<tr><td><input type='submit' value='Submit Details' onClick='validateform'</td></tr>");
						document.write ("<tr><td><input type='submit' value='Calculate Details' onClick='calculateform'</td></tr></table></form>");
						count++
						}
					}

function validateform()		//<=== doesnt run
{				
				element=document.getElementsByTagName ('input');
				for (counter=0; counter<element.length; counter++)
				{
					
					switch (element[counter].type)
						{
							case "submit":
							break;
							default:
							if (isNaN(element[counter].value) || (element[counter].value == "") )
								{
									alert("You need to enter a number into " + element[counter].name);
									flag="NotOK"
								}
							else
								{
									Bike=element[0].value;
									TV=element[1].value;
									iPod=element[2].value;
									Car=element[3].value;
								}
							break;	
						}
				}
}

function calculateform()	//<=== Doesnt run either
{
			if (flag=="OK")
				{
					if	(	(Number(element[Bike])) && (Number(element[TV])) && (Number(element[iPod])) && (Number(element[Car]))	)   //<========= Gets Bike is not defined error easy//
						{
						
						TotalMoney= parseFloat (Bike) + parseFloat (TV) + parseFloat (iPod)
						if 	(TotalMoney >= Car)
							{
							alert ("The total money is " + TotalMoney + " and the car price is " + Car + " and you can afford the car")
							}
						else
							{
							alert ("The total money is " + TotalMoney + " and the car price is " + Car + " and you cannot afford the car")
							}
						}
				}
}
		</script>

Code:

<html>
<head>


<script>
//declare variable
//var temp = 0;
var Num = parseInt(prompt('Enter an Intger'));


// starts the function factorial
factorial(Num);

//The function is declared
function factorial(currentNumber) {

  if(currentNumber > 1) {
      //temp = temp + (currentNumber);
      factorial(currentNumber - 1);
      alert(currentNumber);
  }
  else {
      alert("here");
  }
}
</script>

</head>

<body>
</body>

</html>

This code is suppose to take the prompt number and keep subtracting one if > 1 but it seems to be not doing that at all and doing the else statement first then + till it gets to the prompt number. I have been staring at it for a while now and cant work it out.

Thanks

Hi,
I am creating a mashUp with google maps and have a function that creates the map, marker, infowindow and all works great.
I want to add more functions to that functions file.
Do I start with another function Name() put my function in the {} and then I am going to use the onclick event when I want the function to run.
I also am going to add more functions to this file

Is that the correct way to keep adding functions?

And what is the best way of calling them in my html file?

Answers and examples would be great

thank you

im no jQuery rookie

but for the first time ...instead of simply writing out the animation

jQuery('element').hide()

in that way.... i instead needed to keep track of the functions so i wrote it like

function hidetheElement() {
jQuery('element').hide()
}

but now i need to run 2 of those functions together after a click ...for example

jQuery('ClickedElement').click(
movethelement,hidethelement
)

see what i mean?....i dont know how to properly run two defined functions
whats the proper syntax....


and here is my actual code for reference
(its basically a menu link being clicked...hiding one page...and showing another....i needed to define the functions so if a menu link is clicked it could hide every other page first...by function....and then call a function to show the page


Code:

jQuery(document).ready( function() {
jQuery('#ladiesmenu').click(
previewoff,ladieson
);

function previewoff() {
	jQuery('#preview').fadeOut(500);
}

function ladieson() {
	jQuery('#ladies').fadeIn(500);
}

.


Why do we have functions without parentheses at times?

Ex 1)
http://www.youtube.com/watch?v=OHYFNDzlDTE (On 2:18)


Ex 2)

At the bottom:
Code:

var panel, flag;

function mousemoveResponse(e)
{ 
 var x, y;

  if( window.event )
  { 
    x= event.x; y=event.y; 
  }
  else if(e)
  { 
    x=e.pageX; y=e.pageY; 
  }

  if(flag)
  {
    panel.innerHTML = "Mouse is at X: " + x + ", Y: " + y ; 
  } 
}

function mouseoverResponse()
{  
  flag = false; 
  panel.innerHTML = "Mouse is Over"; 
}

function mouseoutResponse()
{ 
  flag = true ;
}

function init()
{
 panel=document.getElementById("panel");
 flag = true;
 panel.innerHTML="Move the mouse..." ;
 
 document.onmousemove=mousemoveResponse;
 panel.onmouseover=mouseoverResponse; 
 panel.onmouseout=mouseoutResponse; 

}
 onload=init; 

I need to input the functions for the buttons ( Push, Pop,Peek, Enqueue, and Dequeue) nothing I try works. Can anyone possible help me with one of the push, pop or peek, and then one of the Enqueue or Dequeue (any information I see online always has to do with wordpress which im not using) . Im really not asking for someone to do all the work for me, I just need a start. ok here is my code with the buttons just no functions

I'm a newbie student coder for now, hoping to enter the wonderful world of software engineering in another year.

I put together a very simple site for a class and all is well, but my "Contact SRS" form doesn't seem to want to run my JavaScript code even though I've used a JS debugger which returned no errors.

When I click the Submit button it's supposed to validate the form. But I keep getting "Error on page" in the bottom IE 7 message bar (where it usually says "Done" when you load a page). There is another function that also does not work - it's in the Telephone number fields - it' supposed to check that the values entered are numbers.

Would anyone be kind enough to try to run this page in your browser and see if the validation functions runs for you? If they don't, could you offer any suggestions as to code errors or possible browser settings that might be causing the problem?

Thanks in advance to anyone offering their time!!!

Hi, I'm very new to Javascript and I need some help on calling some existing functions.

What i want to do is create a new function to call the first test1 and then call test2 to turn on the checkbox. i hope this isn't confusing.

Code:

function test1(inStore,onSale,newItem)
{
var daURL;
if (inStore==true)
{
BSSetStoreOnly(true);
daURL="s-2-Online-Store.aspx?ms=bsm1";
if (onSale==true){
daURL+='&SaleOnly=1';
} 

} else {
BSSetStoreOnly(false);
daURL="s-1-Our-Products.aspx?ms=bsm1"; 

if(newItem==true)
{
daURL+='&NewOnly=1';
}
}

location=daURL;
}

function test2()
{
var pInc;

chk=document.getElementById("chkAll");
pInc=readCookie("overrideURL");

if (pInc==null)
{
pInc=0;
}
if (pInc==0) {
chk.checked=false;
} else {
chk.checked=true;
}


} 

function callingTest1Test2 {

Okay, here is my assignment:

reate an HTML document with 2 JavaScript functions as described below. Call the document useparameters.html

The first function will use a parameter for the Width of a horizontal rule. When called, the function will draw a horizontal rule of a width specified by the Functions argument. Prompt the user for the pixel width information.
The second function will use parameters for two heading sizes. The parameters will be used for the size of the text that will be displayed on the first line and the size of the text that will be displayed on the second line. The heading size will be different on the first and second lines. Prompt the user for these two headings as well (one prompt for each).
The body of the HTML document will contain a page heading and call the two functions you created, displaying a horizontal rule and two lines of text which will be formated based upon the parameters the user entered into the prompts.

Here is my code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Use Parameters</title>

<script type="text/javascript">


<!--
var hrsize

var htwosize

var psize

function bar()

{
hrsize = window.prompt( "Please enter the size you want your horizontal rule to be (in pixels)", 50 )
hsize = hrsize
document.write("<HR ALIGN='left' width=" + hrsize + ">");
}

function output()

{
htwosize = window.prompt( "Please enter the size you want your heading to be (in pixels)", 18 )
htwosize = htwosize
document.write("<h2" + htwosize + "/h2>")
}

function output()

{
psize = window.prompt( "Please enter the size you want your paragraphcs to be (in pixels)", 12 )
psize = psize
document.write("<p" + psize + "/p>")
}
-->
</script>

</head><body>
<script type="text/javascript">
<!--
bar(hrsize)
output(htwosize)
output (psize)
-->
</script>

<h2>JavaScript Rules!</h2><p>Using JavaScript is fun! </p>

<p> This is some standard HTML, unlike the above which was generated with javaScript.</p>


</body>
</html>



What am I doing wrong?
