JavaScript - How To Add A Radio Button With Numeric Value To Javascipt Cost Calculator

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>

Hello I am very new to Java Script. I am working on a website which requires me to use it. The site is selling items that are priced depending on the size. There are 6 fixed sizes for the width and the length can come in any size 1 through 200. So that will be user input on the length and radio buttons on the width. I am trying to have the user put in the length and click a radio button for width and then calculate the price by multiplying them. I am trying to get 1 price to display right now just to test it but I can't figure out why it isn't working. Again I am fairly new at this so there might be multiple problems with my code. Thanks in advance for the help.
Code:

<script type = "text/javascript">
function buttoncheck(){
	var selection1 = document.menu.selection;
	if (selection1 == 60) {choice1()}
	if (selection1 == 50) {choice2()}
	if (selection1 == 25) {choice3()}
	if (selection1 == 10) {choice4()}
	if (selection1 == 4) {choice5()}
	if (selection1 == 2) {choice6()}
	
function choice1(){
	var len = Number(document.getElementById("length").value) || 0;
	var area1 = selection1 * len;
	var cost = 0;
	if (area1 == 60) { cost = 60}
	return cost;
	document.getElementById("TotalCost").innerHTML = "$" + cost.toFixed(2); 
}

Code:

<h4 class="auto-style3">Pricing Calculator:</h4>
<p>
<form method="post">
	<div class="auto-style1">
		<span class="auto-style2">LENGTH:</span>
		<input name="length" type="text" id="length" /><br />
</form>
	<div class="auto-style1">
	
<form name="menu">
<input type="radio" value="60" name="selection">60 inch</input>
<input type="radio" value="50" name="selection">50 inch</input>
<input type="radio" value="25" name="selection">25 inch</input>
<input type="radio" value="10" name="selection">10 inch</input>
<input type="radio" value="4" name="selection">4 inch label</input>
<input type="radio" value="2" name="selection">2 inch label</input>
</form>


&nbsp;</div>
	<p class="auto-style1">

			<input type="button" value="Calculate" onClick="buttoncheck()" </p>
</p>
<p>&nbsp;</p>
			&nbsp;<span id="TotalCost"></span><script type = "text/javascript">
		document.getElementById("TotalCost").innerHTML = "Total cost is $" + cost.toFixed(2);

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 = "block";

   		 }
 }


addLoadEvent(toggleForm);

Code:

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

      oldonload();

    }
  }
}



addLoadEvent();

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?

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,

~Wayne

I'm trying to get the value of a radio button when clicked.

I'm dynamically creating these radio buttons while populating a table like this:


Code:

var rad
for(blah blah blah){
insert array data into table...
insert array data into table...
insert array data into table...
rad = document.createElement('input');
		rad.setAttribute('type', 'radio');
		rad.setAttribute('name', 'options');
		rad.setAttribute('value', id);
		rad.onclick = function() { doSomething() }; 
		cell.appendChild(rad);
}

If I'm in the doSomething function, how do I access the value or ID of the radio button?

Thanks!

Wondering how come this doesn't work any ideas? its validating that the radio buttons have been selected.

Code:

if ( ( form.q1[0].checked == false ) && ( form.q2[1].checked == false) && ( form.q3[2].checked == false )) { alert ( "Please Choose a " ); return false; }

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;}
  }

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.

Hi,

I am trying to use the radio button to display the information for the users. For example, when I click radio button "1", the form should display 1 text box each for first name, last name and so on. When the user clicks on radio button 2, there should be text boxes displayed for user 1 and user 2 to enter their info(first name, last name and so on).

I looked at the forum, but couldn't find something similiar.Please advise.



Something like
================================
Number of Users 1 2 3

# if radio button 2 is selected then

User 1
First Name
Last Name

User 2
First Name
Last Name

================================

The code is as below:

<html>
<head>
<script type="text/javascript">

function showUser()
{

for(i=0;i<document.form.users.length;i++)
{
if (document.form.users[i].checked)
val=parseInt(document.form.users[i].value);
for(j=0;j<=val;j++)
{
document.form.write("<table cellSpacing=1 cellPadding=0 width=600 border=0>");
document.form.write("<tr>
<td width='20%' align='right'><font color="#660000"><b>First Name:&nbsp;</b></font></td>");
document.form.write("<td><input type='text' name='fname1' size='25' maxlength='25'></td></tr>");
document.form.write("<tr><td width='20%' align='right'><font color="#660000"><b>Last Name:&nbsp;</b></font></td>");
document.form.write("<td><input type='text' name='lname1' size='25'maxlength='25'></td></tr>");
document.form.write("</table>");

}
}

}

</script>
</head>
<form>
Check the number of users to display additional input fields.<br><br>

<input type="radio" name="users" value="1" onclick = "showUser()"/> 1<br/>
<input type="radio" name="users" value="2" onclick = "showUser()"/>2 <br/>
<input type="radio" name="users" value="3" onclick = "showUser()"/>3 <br/>

</form>

</html>

========================================================
Thanks in advance.
