JavaScript - Help With Dynamic Radio Button Input...
MY PROBLEM:
The problem is with 3 radio buttons - each of which changes the view of the current page by passing parameters to the end of the page url. Code: <td>
<input id="vall" tabindex="0" type="radio" name="sortview" value="all" onClick=" changeView(''); "></input>
</td>
function changeView(viewNumber) {
// First, we break the current URL into variables
var hurl = window.location.hostname;
var purl = window.location.pathname;
var surl = window.location.search;
// Then we reconstruct them
var url = hurl+purl;
// If there are parameters on the end of the URL
if (surl.indexOf("?") != -1) {
// And we are requesting a specific view of the "Opt In" field
if (viewNumber) {
// Strip the ? from the front of the parameters
var oldParam = surl.split("?");
// If any of the parameters are "opt"
if (surl.indexOf("opt") != -1){
// Then reconstruct the parameters with the requested view (how??)
}
url = "http://" + url + "?opt=" + viewNumber + oldParam[1];
}
else {
url = "http://" + url;
}
alert("opt found in url: " + surl);
window.location.href = url;
}
else{
if (viewNumber) {
url = "http://" + url + "?&opt=" + viewNumber;
}
else {
url = "http://" + url;
}
alert("opt not found: " + url);
window.location.href = url;
}
}
Is this even the most efficient way of doing this? I feel like there must be a better way. Similar TutorialsI'm trying to use an onclick function in a radio button to change the value of a hidden input in another form. What I want to happen is, when the user changes the value of the radio button (0 or 1), the value of the input named 'repeat' is set to 0 or 1 accordingly. The goal being that when I submit the form with input name='repeat' it will send the number indicated by the radio button. (Due to the structure of my page the radio button and the hidden input need to be two separate forms, but I don't think that should be a problem.) The code below isn't working -- the alert("changerepeat called") never even appears. It seems like the problem is that the onclick isn't even activating at all. Any ideas? Code: <script type="text/javascript">
function changerepeat(theval) {
alert("changerepeat called");
document.forms[0].elements[0].value = theval;
}
function tellme() {
alert("repeat = "+document.forms[0].elements[0].value);
}
</script>
<form>
<input type='hidden' name='repeat' value=''>
<input type='button' value='tellme' onclick='tellme()'>
</form>
<form>
<input type='radio' name='changerepeat' onclick='changerepeat(\'0\')'> 0
<input type='radio' name='changerepeat' onclick='changerepeat(\'1\')'> 1
</form>
Thanks very much for reading! Hey I'm trying to create a function which when my "other address" radio button is checked, the "address2", "suburb2" and "postcode2" fields MUST be filled out by the user. I think I need to be using a for loop to determine which button is checked , but I don't know how to apply this checked button to prompt my client that the remaining fields must be completed (as seen in red)? Here is what I have come up with so far...

I've had a search on Google and found a couple of potential solutions but nothing seems to work quite right for what I need. Basically I have a form with several questions followed by Yes/No radio buttons. Dependent on which answer is given, I want to display a different message above the text box. For example, if you answered 'no' to a certain question then the message above the text box would change to say "Please fill in additional information" or something along those lines. Below is the HTML to give you an idea of what I mean. Code: <table> <tr> <td> </td> <td><label class="bold">Yes</label></td> <td><label class="bold">No</label></td> </tr> <tr> <td><label for="property_q1"> - Is this your house?</label></td> <td><input name="property_q1" id="property_q1" type="radio" value="Yes" /></td> <td><input name="property_q1" id="property_q1" type="radio" value="No" /></td> </tr> </table> <br /> <div id="fine">It's fine, don't worry about filling it in.</div> <div id="fill" style="display:none">Please fill in the form below.</div> <table> <tr> <td> </td> </tr> <tr> <td><textarea name="info" id="info" cols="60" rows="5"></textarea></td> </tr> </table> <input type="submit" /> Hello everyone. I'm new to programming, although I've learned HTML and CSS pretty thoroughly. I think I have most of the Javascript basics down as far as definitions, but I'm getting hung up on the actual coding. I'm working on an information request form for my fiancee's business site. In it, I want to have options that users select via radio buttons. Rather than having additional input fields static on the page, I would like to program some of the radios, when clicked, to open a previously unseen option where users will then be able to type in the necessary information. More specifically, since she only works in two states, I want a third option of "other," which, when opened, will allow the user to input any other state. Then, should the radio be deselected or reset, the field would disappear again. If my understanding is correct, I think I will need to use a javascript function in the header, an HTML "div" section with ID, "onclick" and "offclick" events in the button mark-up, and the specific javascript code to call the function (getElementById?). Or maybe I'm way off. Please help. Thanks 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 I have a problem with adding new inputs to a form (if and when required), Internet Explorer is fine but in Firefox if any previous input fields are filled when the more button is clicked they get reset to blank. JS: Code: fields = 0;
function addInput() {
if (fields != 100) {
document.getElementById('input').innerHTML += "<input type='text' name='input[]' size='30' />";
fields += 1;
} else {
document.getElementById('input').innerHTML += "<br />Maximum 100 fields allowed.";
document.form.add.disabled=true;}
}
form: Code: <form action="index.php" method="post"> <div id="input"> <input type="text" name="input[]" size="30" maxlength="15" /> </div> <!-- button --> <div id="more"> <input type="button" onclick="addInput()" name="add" value="More" /> </div> <!-- // button --> <input type="submit" name="submit" value="Submit" /> </form> as usual any help is appretiated .. Hi, I have an HTML table dynamically populated with data from a coldfusion query and having radio buttons - see code following below. I need javascript to see the radio buttons and the user's selection - "approved"; "denied"; or, "N/A". If the user selects "approved" for multiple rows and then Submit the information will update the database table and remove those rows. However, if the user selects "approved" and "denied" then I need to update the "approved" rows and stop the update at the "denied" row and show a dialog box which informs the user that the "Reason for Denial" text box must be entered. Then the Submit button can be engaged and the "denied" selection processed. Only one "denied" at a time will be updated - but all "approved" entries can be denied similtaneously - unless a "denied" intervenes. I do have javascript code for the "denied" selection with empty "Reason for Denial" text box - see below: Code: <script type="text/javascript">
function rationale() {
var denInfo = document.getElementById("denialReason");
if(denInfo.value == ""){
alert("Please enter reason for denial in Rationale for Request Denial");
return false;
denInfo.focus();
}
}
</script>
The overall action seems like it would need some extensive javascript coding and I haven't a clue how to do it. Any help is GREATLY APPRECIATED. Code: <table border="1" cellspacing="1" cellpadding="2" style="position:relative; left:50px;" width="1000">

Thank you, John 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. 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>
</form>
hi guys im trying to check whether a radio button is checked when i click it, but the javascript onlick event is not acting cool! when i click an unselected radio button i am informed that the unselected radio button i just clicked is in fact checked, when i should be getting the information the no, the radio button was not checked when i clicked it. any idea how to get the previous state of a radio button onclick? Hello, I am trying to implement a radio button option so that users can search specific sites such as google, yahoo, or bing from input box. Here's my code. Please help. <script type="text/javascript"> <!-- function goSearch(){ //search according to checked radio button } --> </script> <h1>Search Option</h1><br /> <input type="radio" name="search" id="google"/><a href="http://www.google.com" rel="nofollow" target="_blank"><img src="images/google.jpg" /></a> <input type="radio" name="search" id="yahoo"/><a href="http://www.yahoo.com" rel="nofollow" target="_blank"><img src="images/yahoo.jpg" /> </a> <input type="radio" name="search" id="bing" /><a href="http://www.bing.com" rel="nofollow" target="_blank"><img src="images/bing.jpg" /> </a> <br /><br /> <form method="get" action="goSearch()" rel="nofollow" target="_blank"> <div style="border:1px solid black;padding:4px;width:20em;"> <table border="0" cellpadding="0"> <tr> <td> <input type="text" name="q" size="25" maxlength="255" value="" /> <input type="submit" value="Search" /> </td> </tr> </table> </div> </form> 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. 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 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'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! 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 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>
hi, how I can execute this operation : for example x=a+b where "a" it can have value 0 or 1 based on the selection of the radio button. when a user select 1 on the radio button x=1+b when user select 0 x=0+b . please help me. 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! |
