Nested Javascript	View Content

Hello. I was wondering if there is a way to call a second Javascript function from within the first. For example:
<script>...call first function...</script> Inside first function:
If (a==1) <script>...call second function...</script> else (a==2) <script>...call third function...</script> My thinking as to why I would need this is because I need to access two different Google Maps API codes.

If that isn't possible, does anyone have any other suggestions?

Nested Javascript Array

Sorry folks, Im not sure that I am using the correct terminology here.

What i would like to do is sort an array based on the [SortBy] value, however this array is nested. For instance:

ar.[SortBy]"PartNumber"
ar.[0].[PartNumber]"123"
ar.[0].[PartName]"Widget1"
ar.[1].[PartNumber]"345"
ar.[1].[PartName]"Widget2"
ar.[2].[PartNumber]"456"
ar.[2].[PartName]"Widget3"
ar.[3].[PartNumber]"567"
ar.[3].[PartName]"Widget4"

Thanks!

Calling Nested Javascript Functions

Similar Tutorials

View Content

Hi, i was wondering if there was a way to call a nested javascript function directly, from outside of the function its nested in?

for example, if i have the following functions:
Code:

<script type="text/javascript">
var test = function(){
	var testInner = function(){
		alert('testInner');
	}
}
</script>

can i then call the 'testInner' function directly from an onclick action something like this:

Code:

<a href="#" onclick="test.testInner()">TEST JS</a><br /><br />

That code is obviously not working for me, but is there something similar to what ive shown here that will work?

Thanks in advanced

Nested Methods And Properties In Javascript

Hi all! I'm pretty new to JavaScript and completely new to this forum. I'm James.

Well uh, I'm not sure how to...

I wanted to make something like this using javascript...

Code:

myObject.someMethod('something').anotherProperty

much like the

Code:

document.getElementById('someId').style.morestuff

But the thing is, I've been around every DOM whatnot I can find, I just can't seem to make it work.

I kinda need it to make my own DOM for some API i'm writing. So I can write like...

Code:

function someGreatAPI(){
     this.property1='';
     this.property2='';
     //...
     this.method1 = function(var1){            //this should make my firstMethod
           this.nestedProperty = 0;
           this.nestedMethod = someFunction;  //firstMethods nested method

     }
}

//so I can use it like...

var obj = new someGreatAPI();
obj.method1(10).nestedMethod();

It has to be possible, it's possible with document.getelementbyid, right? it has to be.

Thanks in advance.

Hi

I need help to finish this code with using nested if statements

A price of a ticket to a passenger will be:
First Class 500
Economy Class (with meal) 400
Economy Class (without meal) 200
How I can write a JavaScript code according to the following specifications:
a. Read the class that the passenger wants to travel on.
b. If the class is the first class, print the price of ticket.
c. If the class is the economy class, ask the user if he/she wants a meal on
the flight. Then print the price of the ticket according to the response of
the passenger.
The program should simply accept one possible strings the user enters; it is not
required to work for all possible inputs such as First, first, FIRST or Yes , yes, YES.
This is the code which I have been trying
{
var inputNum = prompt("Enter the class you want\n first class?\neconomy? :");
if (isNaN(inputNum)) {
if (inputNum.match(/first class/)) {
document.write("<h1><center>your Ticket is 500<\center><\h1>");
}
else
{
prompt("<h1>if you want a meal on the flight press OK <\h1>");
document.write("<h1>your ticket is 400<h1>,");
}
}

Hello codingforums.com!

Right, this is probably going but such a stupid newbie thread but here goes..

I've finally got myself into gear to start learning javascript. I've been watching video tutorials, learning from websites and simply learning by error.

I understand the concept of for loops, but the whole nested thing doesn't seem to click for some reason. I thought i understood and managed to write a piece of code that constantly writes '*' across the screen.

Could someone with some pretty damn good knowledge of javascript be able to walk me through step by step of my script to explain what actually is happening? It would help loads.

here is the script, many thanks!!

<script type="text/javascript">
var counter = 0;

function writeStars(){
for(i=0;i<1;i++){

for(a=0;a<=counter;a++){

document.write("*");

}
counter++
document.write("<br />");
}
}

setInterval("writeStars()", 200);

Nested Objects

I'm trying to reuse some code in a different context to do a different job.

The code to be reused contains hundreds of lines similar to a = new b.c.d(e,f) with different value for e and f.

I need to create a new user defined object with the structure b.c.d. I've made numerous attempts along the lines of:

Code:

function d (e, f) {
   this.e = e;
   this.f = f;
}

function c () {
   this.d =  d (e, f);
}

function b () {
   this.c = c;
}

var a = new b.c.d("test", "message");

with various permuations of functional declarations.

However I get error message "Object expected" or "b.c.d is null or not an object" at the final line of the example.

It works with the test line var a = new d("test", "message") but not when I start to build up the expression.

How should I define of b.c.d?

Nested Loops

Hey Guys,

I'm currently a seasoned programmer who is in a programming class at my school. We're currently learning advanced JavaScript, and we're on the topic of nested loops.

After teaching us about for and while loops, my teacher gave us a little puzzle to solve. It's kind of difficult to explain, but I'll give you guys my current code and what it outputs.

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>Word Reversal</title>

<script type="text/javascript">

var ask = prompt("How many words do you want?","");

while (ask < "1")

{

	alert("You have to have at least one word!");

	var ask = prompt("How many words do you want?","");

}

var num = parseInt(ask) + 1;

var final = "";

for (var i=1; i < num; i++)

{

	var word = prompt("What's word " + i + "?");

	final = final + "Word " + i +": " + word + "<br/>";

}

</script>

</head>

<body>

<script type="text/javascript">

document.writeln(final);

</script>

</body>

</html>

The current output, when the user wants two words, and word 1 is one and word 2 is two, comes out to be:
Code:

Word 1: one
Word 2: two

Which is great, but the only problem is, this is what the output's supposed to be:
Code:

Word 2: two
Word 1: one

I'm stumped. I've had numerous programming challenges in my life which I've solved, but I'm not sure where to go next on this one. The script is supposed to use a nested loop, but what goes in what loop to reverse the order of the user's input?

I asked my teacher for help, but he told me "Ask someone else." I asked another seasoned programmer in my class, who was just about as stumped as I was, so I went back to my teacher. "Well, ask another person" he replied. And can you believe this guy has a Master's Degree of Computer Science? So I'm asking you guys: the community. I hope someone will be able to help me.

On top of that, I have to help and tutor two special education students in my class on this kind of stuff during class, and they can't get the project done until I get it done, as they learn from analyzing and copying my work (which my teacher told me to do). They get upset when they have nothing to code, and they end up goofing off the entire period, or using it as a study hall. I need to get them back on track, so we can move on to the next project.

Please help me with this code - it would be greatly appreciated.

Thank you!

Need Help With Nested Else-if Statements

This may be a basic programing problem but I am writing a function to validate a form using a bunch of else-if statements and encounters a problem when I use nested if/else-if statements. It will not continue on to the next else-if, after it returns false.
Code:

// to check each entry on the form and alert user if entry is invalid.
function checkform(){
  var checkssn = /(\d{3})-(\d{2})-(\d{4})/;
  var checkphone = /(\d{3})-(\d{4})/;	
  var checkname = /[a-zA-Z]+(\.|,|\s)*/;
  var checkzip = /(^967|^968)\d{2}(-\d{4})?$/;
				
  // check to see if user have selected an Election
  if (!document.f1.elections[0].checked && !document.f1.elections[1].checked && !document.f1.elections[2].checked && !document.f1.elections[3].checked) {
	window.alert("Please select an Election!")
	return false;
// check to see if user entered a valid SSN
  } else if ( checkssn.test(document.f1.ssn.value) == false){		
	window.alert("[1]. Please enter a valid social security number in the format ddd-dd-ddd");
	return false;
				
// check to see if user entered a valid home telephone number or business telephone number
  }else if ( document.f1.home_phone.value == '' && document.f1.business_phone.value == '') {
	window.alert("[4]. Please enter a Home or Business telephone number!")	
	return false;
  } else if ( document.f1.home_phone.value != ''){ 
	if (checkphone.test(document.f1.home_phone.value) == false){		
                window.alert("[4]. Please enter a valid home phone number in the format ddd-ddd");
	        return false;
        }
  } else if ( document.f1.business_phone.value != ''){	
		if ( checkphone.test(document.f1.business_phone.value) == false){		
			window.alert("[4]. Please enter a valid business phone number in the format ddd-ddd");
			return false;						
		}	
 // check to see if user entered a valid Name
  }else if ( checkname.test(document.f1.lastname.value) == false){		
		window.alert("[5]. Last Name can only consist of letters, periods(.), commas(,) and spaces");
		return false;
}else if ( checkname.test(document.f1.firstname.value) == false){		
		window.alert("[5]. First Name can only consist of letters, periods(.), commas(,) and spaces");
		return false;

The problem occurs when it validates the phone numbers. When a valid number is entered, it will not move to the next else-if statement to validate the name. It's been years since I program in Java/C, so I'm a bit rusty.
Any help is appreciated.

Ie Issue With Nested Loops

Okay, I have another problem. I really can't figure out why it's not working in IE. The only problem I can think of would be using nested loops. Here's the part of the code that isn't working. It's not generating an error, it's just not returning anything. I know you guys hate when I post entire code, so I trimmed it down as much as I can. It's referring to an already stated xml document with xmlDoc. And it's goal is to return a table of rows that meet certain criteria. If you can see any syntax errors that explorer would not like, that's really what I'm asking for. Thanks in advance,

Julian

Code:

	var entries = Array.prototype.slice.call(arguments, 1);
	var headers = 0;
	for (var i=0;i<xmlDoc.getElementsByTagName('entry').length;i++) {
	  var x = headers;
	  headers += xmlDoc.getElementsByTagName('header').length;
	  var id = xmlDoc.getElementsByTagName('entry')[i].getAttribute("id");
	  if (entries.indexOf(id) >= 0) {
		content += '<tr>';
		for (x;x<headers;x++) {
		  content += '<td>' + xmlDoc.getElementsByTagName('item')[x].firstChild.nodeValue + '<\/td>';
		}
	  }
	  content += '<\/tr>';

Nested If Statement Nightmare.

I have a nested if that is not working, well I have two which are pretty much the same code apart from one has more conditions. The one with the least does not work.

It is basically a quick password checker to see if the typed password matches the previously typed and then display an image according.

Code:

function checkPass(id){
	
	var pass = document.getElementById(id).value;
	
	if(pass == "")
		{
			notValid(id);
		}
	else if(id == "pwd2" && pass !== document.getElementById("pass").value || document.getElementById("pass").value == "")
		{
			notValid(id);
		}
	else
		{
			isValid(id);
		};
};

If it is blank it calls notvalid and if the second if flags it calls notvalid however if it is ok then it does not do the else.

Any ideas??

Thanks.

    document.writeln(uniqueNo()); // 1st time call

the result is 1 2 3

why after the 2nd call, the declaration 'var no=0' is useless -- seems 'no' is updated and stored each time it is called?

Nested Timeouts - How To Implement?

Similar Tutorials

View Content

I'm running into issues while trying to make some simple code to loop through and display different combinations of 3 colours.
I want to show 3 boxes on screen and then loop through/increment each possible combination of colours.

For simplicity's sake I'm trying to go from black to white in each box like this:

(box1rgb/box2rgb/box3rgb)

step 1: 000 000 000
step 2: 000 000 111
step 3: 000 000 222
.
.
.
step 256: 000 000 255255255
step 257: 000 111 000
step 258: 000 111 111
step 259: 000 111 222
.
.
.
step 512: 000 111 255255255
step 513: 000 222 000
step 514: 000 222 111
.
etc.

Yes, I know the thing will take a long time to complete!

The colour is being set by the statement
document.getElementById("box#").style.backgroundColor = "rgb(" + p1 + "," + p1 + "," + p1 + ")"; where p1 is the incrementing variable.

Firstly I tried to do it using nested "for" loops.
Code:

  for (p3=0;p3<=255;p3++) {

    document.getElementById("box03").style.backgroundColor  = "rgb(" + p3 + "," + p3 + "," + p3 + ")";
  
    for (p2=0;p2<=255;p2++) {

      document.getElementById("box02").style.backgroundColor  = "rgb(" + p2 + "," + p2 + "," + p2 + ")";
    
      for (p1=0;p1<=255;p1++) {
      
        document.getElementById("box01").style.backgroundColor  = "rgb(" + p1 + "," + p1 + "," + p1 + ")";
		
      }
    }
  }

But of course the code executes far too rapidly for each combination to be seen. It all chewed up lots of CPU and nothing was smooth.

To slow the process, I tried a single recursive loop using a timeout statement:
Code:

function loopandshow() {
  document.getElementById("box01").style.backgroundColor  = "rgb(" + currentcolour + "," + currentcolour + "," + currentcolour + ")";
  currentcolour += 1;
  if (currentcolour <= 255) window.setTimeout("loopandshow();", 20);
}

This worked smoothly for a single box but I couldn't work out how to nest this format 3 levels deep and have each level increment only when the deeper level had completed the cycle.

Any advice would be gratefully appreciated.

Thanks in advance.
