JavaScript - Radio Button Selections Appear In Second Window
Hi,
I'm learning javascript and not sure what the script language is capable of. Is there a way to make radio button selections appear in a second popup window? Example: user selects various options from a page then clicks button to open a second window with select options showing up in list. Thanks for reading this. Similar TutorialsHello, I need some help! I have some code that has a comments box and 2 radio buttons that ask if you want to be contacted about your comments. If you select "Yes", you get another set of radio buttons that ask you to choose a method of contact. When you choose a method, that selected methods value is parsed to the top of the textarea field, placing the comment below. I pretty much have it working, however, if I enter a comment in the "Comments" field, select "Yes", then select "email" and change to "Phone Morning", it concatnates the values in the textarea box instead of replacing the contact method value while still retaining the comment entered below. Also, if at all possible, I wanted to clear only the contact method value out of the textarea field and leave only the comment when you go back and click the "No" radio button. Can anyone please help? Thanks in advance! Code: <html>

I have 4 rows in a table. Each row consist of 4 radio buttons. Each radio button per row has different values in it but has the same name (group) ex: <input type="radio" name="a" value="1"> <input type="radio" name="a" value="2"> <input type="radio" name="a" value="3"> <input type="radio" name="a" value="4"> <input type="radio" name="b" value="1"> <input type="radio" name="b" value="2"> <input type="radio" name="b" value="3"> <input type="radio" name="b" value="4"> and so on.. If I click radio button A with value 2, I want to output the total at the bottom as "2".. Also, if I click radio button B with value 3, I want to output the total of A and B as 5 and so on.. How can I automatically calculate the answer based on which radio button was click? update: I got my answer from this site: http://stackoverflow.com/questions/1...s-using-jquery 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 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 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  </b><input type="Text" name="textGroup1" value="@gmail.com" /> <br/>
</label>
<br />
<label>
<b>friend2  </b><input type="text" name="textGroup1" value="@gmail.com" />
</label>
</p>

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>

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;}
}

Code: <!-- Row 13, Col 1 Order Value -->

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 Hi guys...I am new to javascript.....I need help with my code below.I need to change it to " the font size of a paragraph should only be changed if the "Magnified" button is selected AND the mouse cursor is over a paragraph. When the mouse moves over a paragraph, increase the font size by a factor of 3. When it is no longer over the paragraph, reduce the font back to its original size" HELP and thanks.... <html> <head> <title>Assignment 4</title> </head> <body> <p> <script launguage="javascript"> var fontSize = 1; function zoomIn() { fontSize += 0.1; document.body.style.fontSize = fontSize + "em"; } function zoomOut() { fontSize -= 0.1; document.body.style.fontSize = fontSize + "em"; } </script> </p> <h2>Joseph’s text zoom and radio buttons</h2> <p>Click on below buttons and see the text getting zoomed in and out..!!</p> <input type="radio" name="radio" value="fontSize -" onclick = "zoomOut()"/> <label for="original">Standard</label> <br><br> <input type="radio" name="radio" value="fontSize -" onclick = "zoomIn()"/> <label for="zoomed">Magnified</label> </body> </html> I am ignorant in java scripting.

Thanks in advance 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. ~Wayne I am looking for some help similar to this old post: http://www.codingforums.com/showthread.php?t=19588 I want my radio buttons to become submit buttons as well. So when a user clicks on a radio button it submits the action and refreshes the page accordingly. As of now using only using onclick="this.form.submit()" the page only refreshes with no change. Here is a copy of the entire form. It is a custom shipping options form (I did not create it). Any help would be appreciated. Code: <!-- Custom shipping 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 == 2) {choice6()}

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. How can I style the background of a radio button? I have a form where it validates the users has selected one of the radio group values. If they don't the group gets focus and I would like to highlight the radio group. I tried the below it it seems focus goes to the correct group but no background changes. Now I know you can change the background of radios and apply a border of you would like. What am I doing wrong woth this. Code: <script type="text/javascript">
function validate(){
document.forms[0].myradio[0].checked = true
document.forms[0].myradio[0].style.border='2px dotted #00f';
document.forms[0].myradio[0].style.backgroundColor='#ffff99';
}
</script>
<form name="test" name="theForm" onsubmit="validate()">
<input type="radio" name="myradio" />
<input type="radio" name="myradio" />
<input type="radio" name="myradio" />
