JavaScript - Calling Javascript Function

I have a page that loads various "applications" into an iframe inside the main page. One of the applications loaded calls a javascript function that is loaded with the "application" page. It works great in Safari, Chrome & Firefox but error's out in IE8 - "Object doesn't support this action". Anyone know why ?
Have other calls that work but this one is the only one that uses href

Thanks,

[CODE]
<div id = 'trainingsubmitbutton' style='display:none;'><a href='javascript: submitdata(0)'>Submit This Record</a></div>
[CODE]

Is it possible to set onmouseover only in js file without running the function on html code?

P.S. I found a coding thread here but I don't understand it and it's too old (2005 archive).

Thank you very much

I have a function which I placed in the header of my html file:
Code:

<script language="javascript" type="text/javascript">

		function UngreyInstallButtons() {
		document.form1.viewbutton1.disabled = false;
		document.form2.viewbutton2.disabled = false;
		document.form3.viewbutton3.disabled = false;
 } 
</script>

I want to call this from within the body of my html page:
Code:

<SCRIPT TYPE="text/javascript" LANGUAGE="JavaScript">
<!--
    var name = GetCookie('COOKIENAME');

	if (name != null) {
	   alert("I GET HERE" + name + "!");
	   UngreyInstallButtons();
	   alert("I DONT MAKE IT HERE");
   	}  
//-->
</SCRIPT>

The GetCookie func works and returns name correctly. The first alert() box is displayed, - the second one isn't!
It does not come back from the call to UngreyInstallButtons()

Why?
I also tried this:
Code:

	if (name != null) {
	        alert("I GET HERE" + name + "!");
		document.form1.viewbutton1.disabled = false;
		document.form2.viewbutton2.disabled = false;
		document.form3.viewbutton3.disabled = false;
	        alert("I DONT MAKE IT HERE");
   	}

Again, it does not execute the = false lines at all.

Perhaps I'm missing something obvious? (I am new to js)

First of all, I must say that I am recently introduced to JavaScript and I am not fully aware of its complete functionality.
So I have an HTML document which has defined within a its body a JavaScript function and I have also a JApplet class which is also loaded in the HTML and can call the JavaScript function. But I have also another Java class which is not an applet and I would like to find a way for this class to be able to call the JavaScript function (but it is essential for this class not to be an applet). I am aware that this would raise some security concerns but it is for local usage and I am interested to hear some ways if possible for this to be done. Thank You beforehand to all of you!

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
http://www.xelawho.com/map/zonesarrowstest.htm

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 am in a class that is right now creating an online quiz that is also displays time. The part I am running into a wall right now is

"Call the runClock() function every second, storing the ID of this timed-interval command in the clockId variable."

I am unsure how to call it every second. Also, how would I call a function within a function? Here is my code so far:

<link href="quiz.css" rel="stylesheet" type="text/css" />
<script src="functions.js" type="text/javascript"></script>
<script type="text/javascript">
var seconds = 0
var clockID =
function runClock() {
clockID = seconds++;
document.getElementById("quizclock").value = seconds;
}
function startClock() {
return showQuiz;
}
</script>
</head>

New here. The issue is this:

I am trying to display two clocks. I used the javascript clock generator (http://rainbow.arch.scriptmania.com/...generator.html) to create both clocks. However, the same code to place in the html was given to call each clock;

<script language="JavaScript">displayTime();</script>.

Below is the code for both clocks. What can be changed so that each clock displays on my website?

Clock 1:


function timeSource(){
x=new Date(timeNow().getUTCFullYear(),timeNow().getUTCMonth(),timeNow().getUTCDate(),timeNow().getUTCHours (),timeNow().getUTCMinutes(),timeNow().getUTCSeconds());
x.setTime(x.getTime()+10800000);
return x;
}
function timeNow(){
return new Date();
}
function leadingZero(x){
return (x>9)?x:'0'+x;
}
function twelveHour(x){
if(x==0){
x=12;
}
return (x>12)?x-=12:x;
}
function displayOnTime(){
if(fr==0){
fr=1;
document.write('<font size=1 face=verdana><b><span id="tP">'+eval(outputTime)+'</span></b></font>');
}
document.getElementById('tP').innerHTML=eval(outputTime);
setTimeout('displayOnTime()',1000);
}
function amPMsymbol(x){
return (x>11)?'pm':'am';
}
function fixYear4(x){
return (x<500)?x+1900:x;
}
var dayNames=new Array('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');
var monthNames=new Array('January','February','March','April','May','June','July','August','September','October','Novem ber','December');
var fr=0;
var outputTime1="dayNames[timeSource().getDay()]+' '+timeSource().getDate()+' '+monthNames[timeSource().getMonth()]+' '+fixYear4(timeSource().getYear())+' '+':'+':'+' '+twelveHour(timeSource().getHours())+':'+leadingZero(timeSource().getMinutes())+':'+leadingZero(tim eSource().getSeconds())+' '+amPMsymbol(timeSource().getHours())";


Clock 2:


function timeSource(){
x=new Date(timeNow().getUTCFullYear(),timeNow().getUTCMonth(),timeNow().getUTCDate(),timeNow().getUTCHours (),timeNow().getUTCMinutes(),timeNow().getUTCSeconds());
x.setTime(x.getTime()+daylightSaving()-18000000);
return x;
}
function timeNow(){
return new Date();
}
function daylightSaving(){
return ((timeNow().getTime()>findDay(0,2,3,2).getTime())&&(timeNow().getTime()<findDay(0,10,3,1).getTime()) )?3600000:0;
}
function findDay(d,m,h,p){
var week=(p<0)?7*(p+1):7*(p-1),nm=(p<0)?m+1:m,x=new Date(timeNow().getUTCFullYear(),nm,1,h,0,0),dOff=0;
if(p<0){
x.setTime(x.getTime()-86400000);
}
if(x.getDay()!=d){
dOff=(x.getDay()<d)?(d-x.getDay()):0-(x.getDay()-d);
if(p<0&&dOff>0){
week-=7;
}
if(p>0&&dOff<0){
week+=7;
}
x.setTime(x.getTime()+((dOff+week)*86400000));
}
return x;
}
function leadingZero(x){
return (x>9)?x:'0'+x;
}
function twelveHour(x){
if(x==0){
x=12;
}
return (x>12)?x-=12:x;
}
function displayTime(){
if(fr==0){
fr=1;
document.write('<font size=2 face=Arial><b><span id="tP">'+eval(outputTime)+'</span></b></font>');
}
document.getElementById('tP').innerHTML=eval(outputTime);
setTimeout('displayTime()',1000);
}
function amPMsymbol(x){
return (x>11)?'pm':'am';
}
function fixYear4(x){
return (x<500)?x+1900:x;
}
var dayNames=new Array('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');
var monthNames=new Array('January','February','March','April','May','June','July','August','September','October','Novem ber','December');
var fr=0;
var outputTime="dayNames[timeSource().getDay()]+' '+timeSource().getDate()+' '+monthNames[timeSource().getMonth()]+' '+fixYear4(timeSource().getYear())+' '+':'+':'+' '+twelveHour(timeSource().getHours())+':'+leadingZero(timeSource().getMinutes())+':'+leadingZero(tim eSource().getSeconds())+' '+amPMsymbol(timeSource().getHours())";

I would like to call a function within a function. Is this even possible??
When I do this I get "undefined"

Here's my code:
Code:

<html>
<head>
<script type="text/javascript">
function product(a,b){
   total = a*b;
   display(total);
}

function display(num){
   return num;
}
</script>
</head>

<body>
<h1>This text I do NOT want to be erased.</h1>

<a href="http://google.com" target="_blank">Total: </a>
<script type="text/javascript">
product(3,4);
document.write(display());
</script>

</body>
</html>

I know you can just return in the first function, "product()" but I would like to do something else in my second function "display()" then return a value.

thanks

I need to create a form button named Create Resume. When clicked this button should call a function that generates a new Web page displaying a resume based on the user input. I am supposed to use the document.write() method to populate a newly generated Web page with all of the XHTML elements, formatting and variable values needed to produce the desired output in Web (.htm) format.

I was hoping to get some guidance on how to accomplish this final step on my project. Any help would be greatly appreciated!

what exactly is this asking me to do? would you provide examples please? thanks in advance!@

Hi Everyone,

I am not able to figure out why the function "changeDiv(the_div,the_change)" is not called from the for loop in the function displayUsers(keeper)that I generated. The displayUsers is written to get rid of excess code in the function display(keeper).

Can someone, please point out what the mistake is?


Code:

function changeDiv(the_div,the_change)
{
  var the_style = getStyleObject(the_div);
  if (the_style != false)
  {
    the_style.display = the_change;
  }
}



function getStyleObject(objectId)
{
  if (document.getElementById && document.getElementById(objectId)) {
    return document.getElementById(objectId).style;
  } else if (document.all && document.all(objectId)) {
    return document.all(objectId).style;
  } else {
    return false;
  }
}



//Shows input information for # of users selected 

function displayUsers(keeper)
{
  var display=keeper;
  var i,user;
  for(i=1;i<= display;i++)
   {
      user="user"+i;
      changeDiv('user','block');
    }
} 


/*function display(keeper)
{
  if (keeper == 1)
  {
    changeDiv('user1', 'block');
    changeDiv('user2', 'none');
    changeDiv('user3', 'none');
    changeDiv('user4', 'none');
    changeDiv('user5', 'none');
    changeDiv('user6', 'none');
    changeDiv('user7', 'none');
    changeDiv('user8', 'none');
    changeDiv('user9', 'none');
    changeDiv('user10','none');


  }
  else  if (keeper == 2)
  ...
  ...
  ...
else
  {
    changeDiv('user1', 'none');
    changeDiv('user2', 'none');
    changeDiv('user3', 'none');
    changeDiv('user4', 'none');
    changeDiv('user5', 'none'); 
    changeDiv('user6', 'none');

Hi,

I would like to do something like this:
Code:

function searchLocations(count) {
    var found = false;
    var input = document.getElementById('autocomplete').value;
	var inp = input.toLowerCase();
	var count = 0;
    for (var j = 0; j < gmarkers.length; j++) {
	gmarkers[j].hide();
	var str=gmarkers[j].myname.toLowerCase();
	var patt1=inp;
        if (str.match(patt1)) 
        {
            found = true;
            gmarkers[j].show();
			count++;
        }
    }
	if (count==1)
	myclick(j);
	if (count>1)
	centerZoom();
    if ( ! found ) alert("No matches found. Please check your spelling or refine your search.");
}

on this page here, but the functions - myclick(j); and centerZoom(); aren't getting called. I tried it with switches here, but that only made things worse.

I know the functions work because if I put them two } up, they get called, but that takes them out of the if statements. Those if (count...) statements have to be where they are so that "count" will get the right value. Any ideas?

In here is an example of a frameset im currently working. i have this frameset: http://www.mediafire.com/?75dvswgvelw19a9

what i want is when i select radio button "YES" and click on the "create" button in form1 http://www.mediafire.com/?eld7a1rb21h799e it will pass the value to radio button "ON" in form 2 http://www.mediafire.com/?f0o060cdpyf06ya and will call the function of the radio button "ON" -shows the hidden textarea. And if i select radio button "NO" in form1 and click on "create" button, it will select radio button "OFF" in form 2. help plsssssssss

Code:

<form>
<input type="button" value="Click!" id="001" />
</form>

function one() {
window.alert('Hello');
window.alert('World!');
}

var varname=document.getElementById("001");
varname.onclick=one;

I am not sure if the last line is this example is correct. Should it not be:

varname.onclick=one();

Or is it ok to write it either way?
Thanks.
