JavaScript - Public And Private Js Functions

From：tibettravel.org

According to source from Lhasa's transportation management office, local vehicles in public transportation, farming and forestry sectors will enjoy a direct financial subsidy from the municipal government of Lhasa, capital city of southwest China's Tibet Autonomous Region.
Urban cabs will get 110 yuan and urban buses will get 100 yuan per month for each while buses of rural routes will ge 120 yuan per month for each.
Transportation service companies should collect the monthly operation information of all vehicles and then report to the municipal transportation management office.
Subsidies will be delivered directly to the companies and then transferred to vehicle owners or drivers after financial verification.

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.

Hey all,

I am having issues with below script. Firebug returns:
form[0] is undefined
[Break on this error] $(form[0].elements).each(function() {

I have this under my form:
<script>
var thisForm = $('#validateForm');
thisForm.validation();
</script>

Hello all,

I want to sell online private lessons using Skype.
I'd like to display on my front page a schedule with my available time-slots so that the customer may click a time-slot and be sent to the product/lesson detail view to complete the purchase.

1. Would it be possible for a JQuery calendar/schedule plugin to know that the customer has completed the purchase and therefore make it impossible for another user to purchase the same time-slot (by changing it's appearance and making it unclickable for example)?
2. Can a JQuery plugin be adapted to that use?
3. Would it be very complex to do for a developer?

Thanks for your advice

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 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.

All,
So I have the following code. It works great. When I add this:
Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

It doesn't work. I need it for some aspects of my CSS to work. The code that works without that is:
Code:

<html>
 <script>
function resizeAll( )
{
    var divs = document.getElementsByTagName("div");
    for ( var d = 0; d < divs.length; ++d )
    {
        var div = divs[d];
        if ( div.className == "fn-area" )
        {
			divid = divs[d].getAttribute("id");
			imgid = "Img" + divid;
			var Div1Width, Div1Height;
    		Div1Width = document.getElementById(divid).offsetWidth;
            Div1Height = document.getElementById(divid).offsetHeight;
            document.getElementById(imgid).style.width = Div1Width;
            document.getElementById(imgid).style.height = Div1Height;
        }
    }
}
 </script>
<head>

</head>
<body onLoad="resizeAll()">
<div id="Div1" class="fn-area" style="width:100px;height:100px; border:1px solid black;" onmouseover="document.getElementById('ImgDiv1').style.display='block';" onmouseout="document.getElementById('ImgDiv1').style.display='none';">
<img id="ImgDiv1" src="fnclientlib/styles/artwork/creep_stamp5.gif" style="display:none"/>
 </div>
 
<div id="Div2" class="fn-area" style="width:300px;height:300px; border:1px solid black;" onmouseover="document.getElementById('ImgDiv2').style.display='block';" onmouseout="document.getElementById('ImgDiv2').style.display='none';">
<img id="ImgDiv2" src="fnclientlib/styles/artwork/creep_stamp5.gif" style="display:none"/>
</div>
</body
</html>

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")
							}
						}
				}
}

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!!!

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);
}

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

.


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; 

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
