JavaScript - Log Global Namespace

Here's my code:

Code:

//document.write("Test");
		
		//Declare arrays
		stats = new Array(6);
		statMods = new Array(6);
		/*
		//Populate stat and statMod arrays
		stats[0] = document.Stats.str;
		stats[1] = document.Stats.dex;
		stats[2] = document.Stats.con;
		stats[3] = document.Stats.int;
		stats[4] = document.Stats.wis;
		stats[5] = document.Stats.cha;
		statMods[0] = document.Stats.strMod;
		statMods[1] = document.Stats.dexMod;
		statMods[2] = document.Stats.conMod;
		statMods[3] = document.Stats.intMod;
		statMods[4] = document.Stats.wisMod;
		statMods[5] = document.Stats.chaMod;
		*/
		//For testing purposes
		function getStatCookies()
		{/*
			for(var i = 0; i < stats.length; i++)
			{
				document.cookie(stats[i], statMods[i]);
			}*/
			
			var testString = "18";
			//document.cookie = cookieString;
			document.Stats.strMod.value = document.cookie;
		}
		
		function getModifiers()
		{
			var strength = document.Stats.str.value;
			var strengthMod = (strength - 10);
			
			//Populate stat and statMod arrays
			stats[0] = document.Stats.str;
			stats[1] = document.Stats.dex;
			stats[2] = document.Stats.con;
			stats[3] = document.Stats.int;
			stats[4] = document.Stats.wis;
			stats[5] = document.Stats.cha;
			statMods[0] = document.Stats.strMod;
			statMods[1] = document.Stats.dexMod;
			statMods[2] = document.Stats.conMod;
			statMods[3] = document.Stats.intMod;
			statMods[4] = document.Stats.wisMod;
			statMods[5] = document.Stats.chaMod;
			
			for(var i = 0; i < stats.length; i++)
			{
				getModifier(stats[i], statMods[i]);
			}
		}

As it is, the array variables are declared globally, and each part is issued a value inside of the function "getModifiers()". When I comment the declarations inside of the function, and uncomment the external declarations, the whole thing falls apart (including the following function). But, if I call this function:

Code:

function saveStats()
		{
			for(var i = 0; i < stats.length; i++)
			{
				var testString = stats[i].value;
				document.cookie = 'stat' + i.toString() + '=' + testString + '; expires=Thu, 31 Dec 2099 23:59:59 UTC; path=/';
				//document.write("Test");
			}
		}

without first calling the other function that actually assigns values, it still works. As I said, though, if I assign values outside that function, then it all falls apart.

Hello.
This is my first post here...
I'm a bit baffled by IE7 javascript engine. I created a very simple game called the "Word Smith"...basically the user has to guess words by clicking a letter or guessing the entire word. Points are assigned accordingly.

After the user clicks "NEW GAME" and then clicks an imagemap of some "dice" to invoke my random number generator, javascript increments the Round number to 2!
Here's the rub...
If I uncomment that "alert" statement just after I increment my currentRound variable, the code works perfectly! WTH? See code below.

Here is a snippet of the code where I am incrementing that variable:
Code:

function generateNumber() {
   //display the current Round
   currentRound++;

//debug
//alert("currentRound = " + currentRound);
//debug

   if(currentRound <= 10) {
      //display the Round Number on the page
      var roundNumberString = 'Round ' + currentRound;
      document.getElementById('RoundNumber').value = roundNumberString;
   }//end if
       .
       .
       .

I declare currentRound as a global var.
This is the only place I increment the variable.

It is also important to mention that this code works great in Firefox, Chrome and Safari -meaning the currentRound variable is incremented once on each iteration.
To reiterate - if you play the game in IE, you will first play not Round 1 but Round 2, followed by Round 4, then Round 6, etc...

Any thoughts? And yes, I am using "onmouseup" not "onclick" in my XHTML.

Thanks for any suggestions.

Cheers.

I am working with the google blogger API, and I am having an issue updating my global variable Response. I thought I understood how global variables worked, so I don't know if there is something different about the blogger API or if I'm making a dumb mistake.

Code:

<SCRIPT TYPE="text/javascript" src="http://www.google.com/jsapi"></ 
script> 
<script> 
google.load("gdata","1.x", {packages: ["blogger"]}); 
google.setOnLoadCallback(getMyBlogFeed); 
blogID = "1601946089552390859"; 
var feedUri = "http://www.blogger.com/feeds/"+blogID+"/posts/full?alt=json"; 
var Response = ""; 
function getMyBlogFeed(){ 
        var myBlog = new google.gdata.blogger.BloggerService('GoogleInc-jsguide-1.0'); 
        myBlog.getBlogPostFeed(feedUri, handleBlogFeed, handleError); 
} 

function handleBlogFeed(myResultsFeedRoot) { 
        Response = myResultsFeedRoot.feed.entry[0].content.$t; 
} 

function handleError(e) { 
        alert("There was an error in getBlogPostFeed"); 
        alert(e.caue ? e.cause.statusText : e.message); 
} 

alert(Response); 
</SCRIPT>

Here's what I think SHOULD happen: Response is initialized as a global variable with a value of "" setOnLoadCallback calls getMyBlogFeed which creates a blog object, then calls getBlogPostFeed which calls handleBlogFeed. handleBlogFeed stores a new string to global variable Response an alert pops up with the value of Response (as given by handleBlogFeed)
What actually happens is that the alert pops up with the original value of Response. I know that I can issue the alert inside handleBlogFeed, but that isn't the issue. My issue is that I'd like to use Response in other functions, but it isn't being updated as a global variable. What am I doing wrong that Response isn't updating?

On a related note, is there a way to return a variable from my handleBlogFeed function? How would I do that? -- I can't seem to figure it out.

Thanks!

P.S. I recognize that the best place to ask this is the blogger developer group. I've already posted this there, and no one has responded yet.

I want to configure ctrl+shift+z as a shortcut for an action in my page. But the key combination is already a global shortcut for my music player.
Can i override the global shortcut or prevent the global shortcut action or just intimate the user that a global shortcut already exists for the key combination

I've read through the past threads and did not find anything that quite
matched my problem, which surprises me because I thought it would be
fairly common.

Anyway, I have a script where I define an array and populate the array.
In the same script is a function that tries to scan the table looking for
a match with the value in a global primitive.

In the HTML, a button click invokes the function. But while the function
can correctly access the global primitive, it simply stops running when
it encounters the reference to the global array.

Here's a shortened, simplified snippet of the code:

[code]

<script type="text/javascript">

var len = 2;
var course_code = new Array();
course_code[0] = "A010";
course_code[1] = "A500";

function runcodes()
{ alert('In runcodes');
alert('len = '+len);
alert('course_code.length = '+course_code.length);
for (i = 0 ; i < course_code.length ; i++)
{alert(course_code '+i+' = '+course_code[i]);}
}

</script>

<body>
<button type="button" name="runc" id="runc" onclick="runcodes()"; >
Click to display course codes table.
</button>

</body>
[ICODE]


When I bring this up in a browser and click the button, I get the
following alerts:

In runcodes
len = 2

and then the script simply stops. So it stops on the first reference
to the array. Clearly I am getting to function, and the function is
able to handle the global primitive 'len', but it stops on encountering
the global array.

I've tried a lot of variations on the the theme, but nothing gets past
this restriction. How do I access elements in a global array from inside
a function?

I'm doing a little project with Java but I've run into some trouble. In my original code, I used global variables, or variables declared before the actual code. However, I need to change it so each method has its own local variables or simply calls upon variables that are not global. Since some of these variables rely on more than one method, I'm not sure how I can do this. I'm trying to use a boolean function, but I'm not getting anywhere. Can any one help?

Hi,

Here's a sample form:

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Sample form</title>
<script type="text/javascript">
function displayResult() {
alert(document.myForm.myInput.value);
}
function getFocus() {
  if (document.myForm.myInput.value == document.myForm.myInput.defaultValue) {
    document.myForm.myInput.value = "";
  }
}
function loseFocus() {
  if (document.myForm.myInput.value == "") {
    document.myForm.myInput.value = document.myForm.myInput.defaultValue;
  }
}
</script>
</head>
<body>
<form name="myForm" method="get" onsubmit="return false;" action="">
<input name="myInput" value="Hello world!" onfocus="getFocus();" onblur="loseFocus();"><br>
<input type="button" onclick="displayResult();" value="Display input value">
</form>
</body>
</html>

It works with no problem, but the following doesn't:

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Sample form</title>
<script type="text/javascript">
var x = document.myForm.myInput;
function displayResult() {
alert(x.value);
}
function getFocus() {
  if (x.value == x.defaultValue) {
    x.value = "";
  }
}
function loseFocus() {
  if (x.value == "") {
    x.value = x.defaultValue;
  }
}
</script>
</head>
<body>
<form name="myForm" method="get" onsubmit="return false;" action="">
<input name="myInput" value="Hello world!" onfocus="getFocus();" onblur="loseFocus();"><br>
<input type="button" onclick="displayResult();" value="Display input value">
</form>
</body>
</html>

What's wrong with it and how can I define a global variable to be used by all the functions?

Many thanks in advance!
Mike

I am trying to figure out how to assign a value to a global variable within a function and can't seem to figure it out. Here's my thought,

Code:

<script type="text/javascript">
var global1=""; var global2="";

function assign(vari,strng){
    vari = strng;
}
</script>...

<input name="box1" onblur="assign('global1',this.value)"/>
<input name="box2" onblur="assign('global2',this.value)"/>
...

The purpose behind this is creating a form that will work with an existing database that would normally have a text area with lots of information. I am trying to turn it into a checklist that I can run from a mobile device. The global variables woudl be used to fill in a hidden text area that would then be passed on to the database upon submission. I am trying to keep the code as compact as possible. Any ideas?

Forgive but I'm quite a beginner at JS . . .


Anyway, on my website I've got a form, and then a script that validates the form. The script for validation is inside a function. The problem is that I have another script outside of the function that generates random numbers to make sure there's not a spambot submitting the form. I set a variable called 'answer' as the correct answer, but for some reason, the variable won't be read when I put it inside the original function to make sure the user got it right.

How should I go about doing this?

Thanks,
Raybob

Hi,

Is is possible to access a global variable for use inside a function?

Thanks for help in advance

Mike

Heres a link to the code in question http://www.scccs.ca/~W0049698/JavaTe...erlocktxt.htm#

when the leftPos variable is used in the moveSlide() it somehow turns into Nan. Cant figure out why and have been racking my brain over this for a long time now.. Any help would be greatly appreciated




the problem is at the end of the code(scroll to the bottom)

=======================================================
Code:

window.onload = makeMenus;

var currentSlide = null;
var timeID = null;


function makeMenus(){
var slideMenus = new Array();
var allElems = document.getElementsByTagName("*");


for(var i=0 ; i < allElems.length ; i++){
if(allElems[i].className == "slideMenu") slideMenus.push(allElems[i])
}



for(var i=0 ; i < slideMenus.length ; i++){
	// alert(slideMenus.length)
	slideMenus[i].onclick = showSlide;
	slideMenus[i].getElementsByTagName("ul")[0].style.left = "0px";
}
document.getElementById("head").onClick = closeSlide;
document.getElementById("main").onClick = closeSlide;
}

function showSlide(){
	slideList = this.getElementsByTagName("ul")[0];
	if(currentSlide && currentSlide.id == slideList.id)
		{closeSlide()}
		
	else{
		closeSlide();
		currentSlide = slideList;
		currentSlide.style.display = "block";
		timeID = setInterval("moveSlide()", 1);
		}
}


function closeSlide(){
if(currentSlide){
	clearInterval(timeID);
	currentSlide.style.left="0px";
	currentSlide.style.display="none";
	currenSlide = null;
}
}

 
	 Code:

	
var leftPos = 0; //reads as a number

function moveSlide(){
	
	leftPos = leftPos + 5; //reads as Nan 
        //have used leftPos += 5 as well if that make as difference
	//alert(leftPos)
	if(parseInt(currentSlide.style.left) <= 220)	
		{currentSlide.style.left = leftPos + "px";}
	else{
		clearInterval(timeID);
		var leftPos = 0;
		}
}

Hey all!

Got a question I can't seem to find an answer to.

I have a little JS app that is a glorified calculator which I posted the code for below. My code uses the document object to replace the html in the "content" <div> and works great.
However, I want to add an inline style in order to change the background of the input (readonly field with an id of "coutput") based on either of the global variables named "MJPD" or "IJPD", (depending on the switch case selected in the user prompt at the beginning of the script.)

Simplified....if the value of MJPD is less than 4.6, I want the "coutput" field's background to be red, else be green.
The same goes for IJPD, except the threshold for red will be <3.83.

Code and what I have tried is below. After reading the code, look below it to see what I have tried and maybe tell me what I'm doing wrong! =)

Any help is greatly appreciated.......I have spent a week searching for this little answer and I can't seem to find it!

Code:

  
<script language="JavaScript">
var MJPD = 1;
var IJPD = 1;
function sayhello(){ //   *** live test for inline JS code placement
alert("IT WORKS!!! Now change me  =)");
}

<script type="text/javascript"> <!-- trying script to ensure function and dynamic update of this value - doesnt work 2/3/2010 -->
document.write(mjpdcolor());
</script>

</div>
</body>

OK, so on the last line of each case statement where it injects html code into the content div, in this code style=" background: ** ** " and in between the ** ** marks, I have added such things as <script type="text/javascript">document.write(mjpdcolor())</script> (or ijpdcolor, depending on which case I am working with).

Theoretically, this should pull the value of MJPD (or IJPD), evaluate it for the if statement, then return the value of red or green and set the value of the background dynamically - but of course it doesnt. I have also tried different inline styles and even adding the css id and trying to link it to the mjpdcolor() function, but all to no avail.

Can someone help me please??

Thanks everyone, your awesome!

I've been fooling around with developing an IETMs interface (Interactive Electronic Technical Manual - like an interactive parts catalogue) to display the data live from an existing Access database. The idea is to be able to run this interface on a network hosted intranet with straight HTML, plain Javascript, VBScript & ActiveX objects, so that it doesn't require IIS etc to run ASP or PHP etc (I don't want to involve corporate IT for the IIS).

All is going pretty well, & I'm impressed with the setup except for a few minor things - checking if a frame is loaded, & global variables.

My setup is a HTML page hosting 5 frames with each containing an empty <DIV> (which gets the page written to it dynamically), but I need to ensure all frames are loaded before getting into the heavy stuff (which Javascript is handling brilliantly!). But I'm finding that Javascript sux at truly detecting if a frame is loaded (someone please prove me wrong!). I have all 5 frames call a function fnInitialiseIfReady(), then if I could either successfully test if all frames are loaded, or if I could globally count if this function has been called 5 times, I can proceed with confidence & call my function fnInitialise(). But unfortunately neither is working for me.

From tireless internet searches, I've tried the 'frames always load in order' theory, & that is simply not correct. I have set up a test with the frames calling a function passing their name as a parameter, & each time the frames load in a different order every time. It is totally random. Note: I proved this by having the first 4 frames call a certain function(which contains an alert() line showing the frame name parameter passed), & having the last frame call a different function (which contains an alert("all are loaded!") line). The "all are loaded!" does not always appear last.

I've also tried the '.frames["FrameName"].document.loaded' approach, & it ALWAYS returns 'undefined' for every frame. Am I doing something wrong here?

I've also tried the '.frames["FrameName"].window.location.href' approach & it ALWAYS returns the html filename regardless of whether that page has loaded or not, so it is not an indicator of loading completion.

I've also tried the '.frames["FrameName"].document.location' approach & it's ALWAYS the same as the '.window.location.href' approach.

Also, I'm finding Javascript will not hold global variables for me at all. I don't know if it's a combination of multiple frames & using Javascript & VBScript together, but global variables just do not hold a value at all. Local variables (within functions) are fine. Any ideas? I don't have many globals, so I'm thinking of using a cookie. A valid Solution?

BTW, the reason for also using VBScript is that it accesses the ActiveX controls by default, & being a corporate intranet app I can guarantee MSIE usage.

It's frustrating because if I can solve these 2 relatively minor issues, then I'm super impressed with the robustness of this Javascript/VBScript approach. By leveraging each of their strengths, it's crunching the data just as quickly as the VB, C#, & C++ programs I've written for this particular dataset. I'm impressed!

Thanks in advance,

Dave Lock.
