JavaScript - Correctly Passing A Radio Button Value

fixed it. my bad. Please delete this thread.

All:

I need some help with a radio button code. It seems simple but I am really new at JavaScript so I need help. I have created a JavaScript code that has three radio buttons (High, Medium, and Low). When you click on high two text boxes appear so that an email address can be added.

What I need help with is making the text boxes disappear if someone accidentally click high and then went back to low or medium. Currently the High button stays clicked and the text boxes still show. Any help would be great.

Thanks,

Stephen



Code:

 <script type="text/javascript"> 
function showHide(el){ 
obj = document.getElementById(el).style; 
   (obj.display == 'none')? obj.display = 'block' : obj.display = 'none'; 
} 
</script> 
<form id="form1" name="form1" method="post" action=""> 
 <label> 
  <input type="Checkbox" name="High" value="High" onclick="showHide('group1')" /> High
  
 </label>

  

    <label> 
  <input type="Checkbox" name="Medium" value="Button" /> Mediun
  </label> 

  <label> 
  <input type="Checkbox" name="Medium" value="Button" /> Low
  </label> 
<p id="group1" style="display: none;"> 
    <label> 
    <b>friend1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp</b><input type="Text" name="textGroup1" value="@gmail.com" /> <br/>
</label> 
    <br /> 
    <label> 
<b>friend2&nbsp;&nbsp;&nbsp</b><input type="text" name="textGroup1" value="@gmail.com" /> 
</label> 
    
  </p> 
  
</form>

I don't exactly know how to word my issue.

Basically, I need it so that if a user selects 'option1' in the group 'group1' when they go to 'group2' is only gives them a certain selection to choose from. If they choose 'option2' in 'group1' they will get a different set to choose from.

My main dilemma is it must do this without them having to submit.

All,
I have the following code:
Code:

<form action="" name="myform" method="post">
<input type="hidden" id="picimages" name="picimages" value="<?php echo $resultsetstory['bigger_id']; ?>" />
  <p>
    <label>
      <input type="radio" id="picimages" name="picimages" value="<?php echo $resultsetstory['picture_id']; ?>" />
      <?php
	  if($resultsetstory['title']<>""){
echo $resultsetstory['title'];
}else{
echo "Image 1";
}
?>
	  </label>
    <br />
    <label>
      <input type="radio" id="picimages" name="picimages" value="<?php echo $resultsetpic2['picture_id']; ?>" />
      <?php
	  if($resultsetpic2['title']<>""){
echo $resultsetpic2['title'];
}else{
echo "Image 2";
}
?>
	  </label>
    <br />
	<input name="submit" type="button" value="Vote!" onclick="javascript:voteupdate(this.myform);"/>
  </p>
</form>

When I submit this, it goes to this function:
Code:

function voteupdate(obj) {
var poststr = "picimage=" + document.getElementById("picimage").value +
"&bigger_id=" + encodeURI( document.getElementById("bigger_id").value );
alert(poststr);
makePOSTRequest('voteresults.php', poststr);
   }

However I can't get the value of the radio group for the one that is selected. Can someone see what is wrong?

Thanks.

I'm trying to make radiobuttons with a javascript function that gets called when a button is selected to make an image appear depending on what they click. However, after looking it up for a while I have nothing since some tell me to do document.formName.name.value; some tell me to use an id with my buttons and just use a document.getElementByID(""); etc.

This is for a project and we havent used parameters yet and I dont know how to implement them in the HTML as well

This is my code:

function classchoice()
{
if(document.getElementById('mage') == true)
{
classtype = "<img class='display' src='mage.jpg'>";
document.getElementById("picture").innerHTML=classtype;
}
if(document.classes.classes.paladin == true)
{
classtype = "<img class='display' src='paladin.jpg'>";
document.getElementById("picture").innerHTML=classtype;
}
if(document.classes.classes.hunter == true)
{
classtype = "<img class='display' src='hunter.jpg'>";
document.getElementById("picture").innerHTML=classtype;
}
if(document.classes.classes.rogue == true)
{
classtype = "<img class='display' src='rogue.jpg'>";
document.getElementById("picture").innerHTML=classtype;
}
}

This is the HTML:

<form name="classes">
<input type="radio" name = "classes" id="mage" onmousedown="classChoice();"> <img src = "mage.jpg" />
<input type="radio" name = "classes" id = "Paladin" onmousedown="classChoice();"> <img src = "Paladin.png" />
<input type="radio" name = "classes" id = "hunter" onmousedown="classChoice();"> <img src = "hunter.PNG" />
<input type="radio" name = "classes" id = "rogue" onmousedown="classChoice();"> <img src = "rogue.jpg" />
</form>


I hope it's readable because I copy and pasted my code and the indentations are a bit messed up

Hello,

I have a form which can be saved (using a database) and later edited.

When restoring data to the form , text fields are easy.

There is a simple (existing) JavaScript which restores an option that was selected from a pull-down (select one) menu:

Code:

  for (var q=0;q<document.Simple.Color.options.length;q++) {
  if (document.Simple.Color.options[q].value == document.Restored.Color.value)
   { document.Simple.Color.options[q]. selected  = true; break; }

I'm trying to make it work to restore a value to a radio button as well... but no luck:

Code:

  for (var q=0;q<document.Simple.Color.options.length;q++) {
  if (document.Simple.Color.options[q].value == document.Restored.Color.value) 
   { document.Simple.Color.options[q]. checked  = true; break; }

Any ideas?

Thanks in advance.

I'm trying to implement a visibility on or off function for extra inputs when a radio button that is "yes" inside a table...

it's so "Are you married?" "Yes" "No" (no is default checked)
when you hit yes I want 3 more rows like a collapse or extend feature...within the same table.

So basically what I want is the table to grow.. If you select "yes" then 3 more rows will be displayed that have other inputs available...

do I need to construct these extra rows in javascript? or can I referance some html to do something? ..I'm just kinda lost and brain farted out today I think...
any help much appreciated.

Thanks!

how would i check to see if my radio button is not checked. I know in javascript the term "checked" works. Is there a way to us unchecked?

here is what i am trying to figure out.


Code:

	with (thisform)
  {
  if(document.getElementById('m21').unchecked) 
  {
  window.alert('Please Verify Your Age')
  m21.focus();
   return false;}
  }

I using the following to read the content of a text field but how do I read the content of a radio button ?

Code:

String.prototype.trim = function () {    //return this.replace(/^\s*/, "").replace(/\s*$/, "");
    return this.replace(/^\s+|\s+$/g, '').replace(/\s+/g,' ');
}

		var fID = document.getElementById('customerName'); fID.value = fID.value.trim();
		if (fID.value.trim().split(' ').length < 2) {
		document.getElementById('customerNameImg').innerHTML = redX;//
		} else {
		document.getElementById('customerNameImg').innerHTML = greenTick;//
		}

this is the part of my form code that i am having problems with
Code:

 <ul>
          <li class="<? if ($empty_Field == "previousClient") {?>emptyfield<? } else { ?>field<? } ?>"> Are you a Previous Client * </li>
          <li class="value">
            <div style="float: left;"><input type="radio" name="previousClient" id="previousClientY" value="Yes" <? if($previousClient == 'Yes') { echo 'checked'; } ?> onChange="checkValidFormInput();"> Yes 
			</div>
			<div style="float: left; padding-left: 20px;">
            <input type="radio" name="previousClient" id="previousClientN" value="No"  <? if($previousClient == 'No') { echo 'checked'; } ?> onChange="checkValidFormInput();"> No 
			</div>
 <div style="float: left; padding-left: 10px;" id="previousClientImg"></div><br style="clear:both"> 
          </li>
        </ul>

Hi all,

This code works to place a mark in a radio button (check one) in a "restored" form:

Code:

for (var q=0;q<document.Simple.Colors.length;q++) {
  if (document.Simple.Colors[q].value == document.Restored.Colors.value) 
    { document.Simple.Colors[q].checked =  true ; break; }

I'm curious why it won't work for a check box (check more than one):

I figured it would be the same... no?

Thanks,

i need to add an alert if the male is not selected in following after clicking on submit button
Code:

<html><head>
</HEAD><BODY>
<br><form name="feedback" method=post>
Your Gender: <input type="radio" name="gender" value="male" id="male" /> Male <input type="radio" name="gender" value="female" id="female"CHECKED> Female</td>
<input type='button' value='Submit' />
</form></BODY></HTML>

Hi everyone. I'm getting into javascript coding and i'm stumped with some problem about radio buttons. What I would like is to have a general function where I can pass in any group of radio buttons and have it return the textual value of the radio button selected. First, here is my code so far.

Code:

function Get_Radio_Selection(options)
{
   var choice = "";

   for (var index = 0; index <= options.length; index++)
      if (options[index].checked == true)
         choice = options[index].value;

   return choice;
}

Now here's a sample form:

Code:

<form name="form1">
   <input type="radio" name="food" value="Banana">Banana
   <input type="radio" name="food" value="Mango">Mango
   <input type="radio" name="food" value="Orange">Orange
   <input type="radio" name="food" value="Oatmeal">Oatmeal

   <input type="button" name="blah" value="Get Selection"
          onclick="Get_Radio_Selection(document.form1.food);">
</form>

My question is, when i run this function and pass it in the group of radio buttons by means of the onclick event handler, firefox 3.6.22 reports in the error console on line 22 that "options[index] is undefined". It seems that if i use the variable "index" more than one time it reports this error but if I take out the assignment to variable "choice" that it works just fine. I rewrote the function using a separate variable and this time it works perfectly:

Code:

function Get_Radio_Selection(options)
{
   var choice = "";
   var index;

   for (var i = 0; i < options.length; i++)
    {
      if (options[i].checked == true)
       {
         index = i;

         choice = options[index].value;
       }
    }

   return choice;
}

Notice the indexing variables in the "if" statement and the assignment to "choice" are different. Does anyone have any suggestions on why this happens? Thanks.

Hi,


Hit a snag creating code for toggling with radio buttons, alert debugs
return undefined for the radio button values. Would someone assist?

	newArtist.style.display = "none";
	
	 if(this.value == existing){

               existing.style.display = "block";
       }else{


             newArtist.style.display = "block";

   		 }
 }


addLoadEvent(toggleForm);

Code:

function addLoadEvent(func) {
  var oldonload = window.onload;
  if (typeof window.onload != 'function') {
    window.onload = func;
  } else {
    window.onload = function() {
      oldonload();
      func();
    }
  }
}



addLoadEvent();

I have the following code which I want to make a selection and the value should reflect in the text box and the text box should take on that value for future calculations.

Code:

<!-- Row 13, Col 1 Order Value -->
<tr><td colspan="2" align="right">Delivery Options: 
<input type="radio" name="sapo" value="35" onclick="deliveryCost('35')" /> R35 - SA Post Office 
<input type="radio" name="sapo" value="80" onclick="deliveryCost('80')" /> R80 - Speed Services 
<input type="radio" name="sapo" value="150" onclick="deliveryCost('150')" /> R150 - Courier Services 
</td>

<!-- Row 13, Col 2 Order Value Box-->
<td colspan="1" align="left"><input style="margin-left: 60px" type="text" name="delivery" size="10" readonly="readonly" />
</td></tr>

As the code example below shows, I have three radio buttons that perform an javascript action when selected.

Code:

<script language="javascript"> 
function OnProductClick(product) 
{	
	if (product.value == "Car")
	{			
		// do something
	}
	else if (product.value == "Boat")
	{
		// do something else..
	}
	else if (product.value == "Train")
	{
		// do else
	}
}
</script> 

<p>Select option
	<input type="radio" name="product" onclick="OnProductClick(this)" value="Car">Car</input>
	<input type="radio" name="product" onclick="OnProductClick(this)" value="Boat"> Boat</input>
	<input type="radio" name="product" onclick="OnProductClick(this)" value="Train">Train</input>
</p>

This setup is triggerred by a click, clicking multiple times on the same radio button will yield multiple calls to the OnProductClick function. This last part is what I would like to prevent. Say a user selects the option 'car' and then for some reason clicks on the same option again, this will lead to the OnProductClick function being executed twice. How can I prevent the second execution?
