JavaScript - My Function Only Fires Once, Why?

Hi!

I'm trying to toggle a class and one works and the other does not and I don't know why. I'm just getting my feet wet with jquery and javascript and I figured this was a pretty easy task to take on! Maybe.

Link to the page:
Franklin Township Soccer Club - Change Field Status

My sad, sorry attempt =|

Code:

	$( "li.open" ).click(function() {
	$( this ).toggleClass( "closed" );
	});
	
	$( "li.closed" ).click(function() {
	$( this ).toggleClass( "open" );
	});

The first function works with open, so I figured I'd just use opposite on closed! Ha! I don't think so!

In the end within those function there is an element in a form on that page it's hidden. I'd like to change the value from a 0 to 1 for vice versa. That' will be my next step. If you could give me a little nudge in the right direction I'd appreciate it! But first understanding why one works and the other does not, that is the primary mission!

I do appreciate any help given!

Hi All, I'm trying to convert an anonymous function to a real function (nesting is getting out of hand), however the msg object becomes undefined after conversion. Here is the converted anonymous function which fails: https://gist.github.com/2587613 and here is the original anonymous function which works: https://gist.github.com/2587667

Any help would be greatly appriciated

i keep getting error Call to undefined function codeandurl()

below is my code
PHP Code:
<?php

$value= strip_tags(get_field('link',$post));
$resultid=get_field('resultid',$post);
codeandurl($resultid,$value);

<script type="text/javascript">
function codeandurl(resultid,url){
$( "#result" ).text(resultid);        
      $( "#result" ).dialog({

I found this script, and it works great:
Code:

<script type="text/javascript">
  function disable(element)
  {
    var input = document.getElementById(element).getElementsByTagName("input");
    for(var i = 0; i < input.length; i++)
    {
      input[i].setAttribute("disabled","true");
    }
  }
</script>

I tried to make the inverse by simply reversing the setAttribute() like so:
Code:

<script type="text/javascript">
  function enable(element)
  {
    var input = document.getElementById(element).getElementsByTagName("input");
    for(var i = 0; i < input.length; i++)
    {
      input[i].setAttribute("disabled","false");
    }
  }
</script>

But that didn't do it.
Can someone show me why, and how to fix it?

Here's the sample form which I'm trying to test it on:
Code:

<form>
  <input type="radio" name="test" onclick="disable('D1')" /> disable<br/>
  <input type="radio" name="test" onclick="enable('D1')" /> enable<br/>
  <fieldset id="D1">
    <input class="" type="text" value="test value1" /><input class="" type="text" value="test value2" /><br/>
    <input class="" type="text" value="test value3" /><input class="" type="text" value="test value4" /><br/>
    <input class="" type="text" value="test value5" /><input class="" type="text" value="test value6" /><br/>
  </fieldset>
</form>

Edit:
The ultimate goal which I'm working toward now (step by step =) is to have a form more like:
Code:

<form>
  <input type="radio" name="test" onclick="disable('D1')" />
  <fieldset id="D1">
    <input class="" type="text" value="test value1" /><input class="" type="text" value="test value2" />
  </fieldset>
  <input type="radio" name="test" onclick="disable('D2')" />
  <fieldset id="D2">
    <input class="" type="text" value="test value3" /><input class="" type="text" value="test value4" />
  </fieldset>
  <input type="radio" name="test" onclick="disable('D3')" />
  <fieldset id="D3">
    <input class="" type="text" value="test value5" /><input class="" type="text" value="test value6" />
  </fieldset>
</form>

And have the fieldsets enable and disable according the selection of the radio buttons.

Also, the fieldsets (and their ID's) will be dynamically generated via PHP



Thanks-a-bunch,

Thank you in advance if someone can help. I have been banging my head against the wall for hours now.

Here is the code:

Code:

for (var i = 0; i < BS_crm['activityTypes'].length; i++) {
        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 made a mouseover event of a caption on a picture, when I hover the opacity of the background color of the hover and the text goes down. What I want is that when I hover over the image which the caption is floating on, the onmouseover event gets activite. For an imaginary example:
Code:

function unhighlight(x) {
x.style.backgroundColor="transparent"
}

Function ActivationFuction()
{
activate.function="unhighlight"
}

thanks

I'm trying to "progressively enhance" one of my surveys using javascript. Basically, I have rating scales that make use of radio buttons as each point on the scale. Each radio button occupies its own cell in a table. I wrote some functions that will highlight cells on mouseover in a color corresponding to its position on the scale (e.g. the lowest point is red, the midpoint is yellow, the highest point is green). When a radio button is clicked, the background of the button's cell and preceding cells in the same row will be colored accordingly. The functions are working well in FireFox and Chrome (I just have to add a few lines using the addEvent function to make it compatible with IE).

The effect looks a lot nicer when I add a function that makes the visibility of the radio buttons hidden.

However, I want to make sure that there is a fallback option in case the functions that color the cells don't work for whatever reason. I would not want the radio buttons hidden in this case.

Is there a method whereby I can call the "hideRadiobuttons" function only if the other functions are successfully executed?

Code:

<html>
<head>
	<title>TESTING</title>
	<script type="text/javascript">
	<!--
	document.write("<input type='submit' value='submit' onclick='func()'>");
	function func()
	{
		document.write("<input type='submit' value='New Button' onclick='func()'>");
		window.alert("THIS");
	}
	-->
	</script>
</head>
<body>
<!--input type="button" value="Read" onclick="ReadFiles()"-->
</body>
</html>

This is a very basic version of what I am trying to do. I have a dynamic list which is set in a table. When clicked, a function is run to set up a new list.. The reason I explain that, is that I need to keep it dynamic.
Now for the problem:
When I run this page, I have the button made right away, then when clicked it creates the new button. The new button should also run the function to create the new button again, but when I click it, I only receive "error on page".

I don't know if there is a better way to go about this, but as for this route, I am stuck.

Any help is greatly appreciated!

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?

PHP Code:
<?php
function phpQuery(){

     $query = mysql_query("INSERT INTO mytable VALUES('','name','email')");

}
?>
<script type="text/javascript">
function delayQueries()
{
  timeoutID = window.setTimeout(doQueries, 2000);
}

function doQueries()
{
  var runQuery = "<?php phpQuery(); ?>";    
}
</script>

Hi,

while running the application i am getting an error incase if the data is string ex:if data is 'image1' i am getting an error, but with number there is no problem ex: if data is '1122'.

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

Hello again!

Is there any way to pass a function(with its parameters) to another function using a parameter?

Examples:
Here is how I do it now:
PHP Code:
function output(text){
    alert(text);
}

function bla(text, func){
    output(text);
}
bla("Text is here", output) //Outputs "Text is here" 


I only want to pass the function to bla() as a parameter.
I need something like this:
PHP Code:
function output(text){
    alert(text);
}

function bla(func){
    output();
}
bla(output("Text is here")) //Outputs "Text is here" 


Is this possible in some way?

Thanks in advance.

i have an image with an onclick function and parameters 0,1

i want to change the parameters of the onclick function through the same function?

Code:

<img id="down0" onclick=swap(0,1) />

<javascript>
function swap(a,b){
var imgda=document.getElementById('down'+a);
imgda.onclick = swap(b,b+1);
}
</javascript>

normally it should change the onclick to swap(1,2)

but it remains 0,1

whats happening??

p.s. plz dont tell me about the javascript tag, its just for quick explaining...

Hi everyone,

I am pretty new at javascript OOP.

I have a javascript file that has plenty of javascript functions, variables, arrays, etc.

I need to convert this into an object.

Here is an example:

Code:

var myvar1 = '';
var myvar2 = new array();
var myvar3 = new array();
var myvar4;
var myvar5 = 60;
var myvar6 = '';

function myfunc1(){
 myvar1 = 'hello';
 return myvar1;
}

function myfunc2(somenum=0){
 myvar5 = somenum;
 //calling myfunc1() from within this function.
 //do something in here
}

function myfunc3(){
 //calling myfunc1() from within this function.
 for(i=0;i<somelength;i++){
   myvar2 = myvar3[i]; (something to put into the array)
 }
}

1. I need to create an object and put ALL the varibles (myvar1 - myvar5) in that object.
2. Then the first two functions "myfunc1 and myfunc2" inside the same object.
2. And the function myfunc3 needs to sit OUTSIDE my object as a regular javascript function. It calls on myfunc1 (which is inside the object) and also inserts data into myvar2 (which is classified inside the object) and myvar3 (which is classified inside the object as well).

This is what i came up with, but it's not going well:
Code:

var myobj1 = function(){
 this.myvar1 = '';
 this.myvar2 = new array();
 this.myvar3 = new array();
 this.myvar4;
 this.myvar5 = 60;
 this.myvar6 = '';

 var myfunc1 = function(){
  this.myvar1 = 'hello';
  return this.myvar1;
 }

 var myfunc2 = function(somenum=0;){
  this.myvar5 = somenum;
  //calling this.myfunc1() from within this function.
  //do something in here
 }
}

function myfunc3(){
 //calling mynewobj.myfunc1() from within this function.
 for(i=0;i<somelength;i++){
   mynewobj.myvar2 = mynewobj.myvar3[i]; (something to put into the array)
 }
}

var mynewobj = myobj1;

HELP.....!!!!
i really want to get into object oriented world, so thanks in advance.

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.
