JavaScript - Variables Inside A Function Aren't Global?

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.

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?

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:

var IJPD = 1;

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.

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?

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?

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++){

	// 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];

}

 
	 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 everyone,

I wanted to write my own script for a fade-in animation, since the ones I have found have got too many options or need some framework, which makes them unnecessarily big. I wanted to learn too.

Unfortunately, the code didn't work as I wanted, and I commented some things so as to find out what's happening.

The only function called from outside is fadeIn with a string as argument (in the example, this string is: d1296668690535). This is the code:

Code:

var fadems = 500;	// Anim. duration in milliseconds
var fps = 20;		// Frames per second

function fadeIn(elemId){
	var frames = fadems/1000 * fps;
	var delay = 1000 / fps;
	var incrOp = 1 / frames;
	
	//document.getElementById(elemId).style.zoom = '1';
	
	setOp(elemId, 0);
	
	for(i=1; i<=frames; i++){
		debugOutLn("(fadeIn for) elemId = " + elemId);
		setTimeout("setOp(" + elemId + "," + incrOp*i + ")", delay*i);
	}
}

function setOp(elemId, val){
	debugOutLn("(setOp) elemId = " + elemId + "; val = " + val);
	// document.getElementById(elemId).style.opacity = val;
	// document.getElementById(elemId).style.filter = 'alpha(opacity = ' + val * 100 + ')';
}

Code:

function debugOutLn(str){
	document.getElementById("debug").innerHTML += str + "<br />";
}

And this is the text it outputs (on Opera 11.01):

Code:

(setOp) elemId = d1296668690535; val = 0
(fadeIn for) elemId = d1296668690535
(fadeIn for) elemId = d1296668690535
(fadeIn for) elemId = d1296668690535
(fadeIn for) elemId = d1296668690535
(fadeIn for) elemId = d1296668690535
(fadeIn for) elemId = d1296668690535
(fadeIn for) elemId = d1296668690535
(fadeIn for) elemId = d1296668690535
(fadeIn for) elemId = d1296668690535
(fadeIn for) elemId = d1296668690535
(setOp) elemId =  [object HTMLDivElement] ; val = 0.1
(setOp) elemId =  [object HTMLDivElement] ; val = 0.2
(setOp) elemId =  [object HTMLDivElement] ; val = 0.30000000000000004
(setOp) elemId =  [object HTMLDivElement] ; val = 0.4
(setOp) elemId =  [object HTMLDivElement] ; val = 0.5
(setOp) elemId =  [object HTMLDivElement] ; val = 0.6000000000000001
(setOp) elemId =  [object HTMLDivElement] ; val = 0.7
(setOp) elemId =  [object HTMLDivElement] ; val = 0.8
(setOp) elemId =  [object HTMLDivElement] ; val = 0.9
(setOp) elemId =  [object HTMLDivElement] ; val = 1

Why is an object reference assigned to what was previously a string?


Thanks for the help!

Hi,

Any one help me

In one variable i have some data ex: var data = document.getElementById("imageId").value;

I want to pass this data to another function inside another function ex:

this is very urgent to solve this problem plz any one help me

How can I call a PHP Function inside a Javascript Function? This is what I have so far, but I don't think I'm doing it the right way.
Any suggestions?

        var clickFunc = function(){ activityList.showForm( -1, {blockType:[""+BS_crm['activityTypes'][i]['id'], "0"]} ); };
        var type = {
                value: BS_crm['activityTypes'][i]['id'],
                label: "Add New "+BS_crm['activityTypes'][i]['label'],
                css: BS_crm['activityTypes'][i]['css']+"_16",
                onClick: clickFunc
        };
        previewLinks.items.push( type );

}

Now, basically what I am doing here is running through one array to
create an array of objects, that will be used to create links that
will use whatever onClick function I pass it. The problem is that on
the second line I need the BS_crm['activityTypes'][i]['id'] to be a
value, not a reference. If that line was simply changed to:

Code:

var clickFunc = function(){ activityList.showForm( -1, {blockType:["3", "0"]} ); };

then everything would work as I need.

How can I make this happen? I would really appreciate any help.

Thank you again in advance.

I have the following code:

...
var numberoffiles = array();

for (i = 1; $i <= totalNumberOfFiles; i++)
{
numberoffiles[i] = i;
}
...

I get an error saying that numberoffiles is undeclared or something
What am I doing wrong?
Do I need to declare it a global variable or something??

ALSO, why can't I do this:

numberoffiles[] = i;

I've seen code snippets that assign to the end of an array like this
(Or maybe my problem is the scope of the variable??)

Thanks

Hi,

I am working on a google map where you can show lines on the map by checking checkboxes. Lines are displayed according to their category attribute in the xml file. The function that picks up the checkbox click is like this:
Code:

 function boxclick(box,category) {
        if (box.checked) {
          show(category);
        } else {
          hide(category);
        }

Another part of the code assigns that category attribute to arrows, so that when a line of "x" category is displayed, the relevant arrows are displayed along with it, to indicate directionality.

I also have a select list which displays the lines by looping through their array and using selectedIndex in a function called handleSelected2. But I can't get the arrows to display along with the lines from the select box. After trying many, many things, I figure that all I need to do is to call the show(category) function from inside the handleSelected2 function and it should all come together. So I came up with this:

Code:

function handleSelected2(opt,category) {     
  for (var h = 0; h <gpolylines.length; h++) {
		  gpolylines[h].hide();
        }
         h = opt.selectedIndex - 1; 
        if (h > -1) {
          gpolylines[h].show();
		 }
		 for (var v=0; v<pts.length; v++) { 
		 show(category); 
		   }
}

which gets me lines, but no arrows. You can see it sort of working he

I figure I've got to be close, because if I just tell it to show all the arrows (without going through the category filter) like this:

Code:

function handleSelected2(opt,category) {     
  for (var h = 0; h <gpolylines.length; h++) {
		  gpolylines[h].hide();
        }
        var h = opt.selectedIndex - 1; 
        if (h > -1) {
          gpolylines[h].show();
		  }
       for (var i=0; i<pts.length; i++) {
		 pts[i].show();
        }
    }

then all the arrows show up, as you can see he http://www.xelawho.com/map/zonesarrowstest2.htm

I'm not getting any error messages and I've tried pretty much everything I can think of... I've been tweaking this for days and it's driving me crazy. Does anybody else have any ideas?

Thanks in advance.

I would like to know (maybe I know the answer already), but can a function be paused, like halfway the function pause the function for lets say for 5 seconds, then continue.

Thanks
