JavaScript - Multiple Radio Button Validation
Hi, i'm new here and I need help.
I need a script that can alert in 2 ways for multiple radio button groups of "yes" and "no." I got the first question to alert the way I need (with alert #1 for yes and alert#2 for no.) However, starting from the 2nd question it alerts #1 for both yes and no. This is the script I'm working with: Code: <script type="text/javascript">
function valbutton(form) {
myOption = -1;
for (i=form.buttonset1.length-1; i > 0; i--) {
if (form.buttonset1[i].checked) {
myOption = i; i = -1;
}
}
if (myOption == -1) {
alert("Please select Yes or No");
return false;
}
if (myOption == 1) {
alert("Yes, it works!");
return false;
}
if (myOption == 2) {
alert("No, it won't work.");
return false;
}
}
</script>
The following are the 1st two sets of radio buttons: Code: <form name="myform" action="formstest.html"> <tr> <td> <input type="reset" value="Click to Reset"> <br><input type="radio" name="buttonset1" value="1" rel="none" id="r1" /><label for="r1">Click to Start Over</label><br /></td> </tr> <tr><td class="question">Question #1</td> <td><input type="radio" name="buttonset1" value="2" rel="flat" id="r2" /> <label for="r2">Yes</label><br /> <input type="radio" name="buttonset1" value="3" rel="none" id="r3" /> <label for="r3">No</label><br /> </td> </tr> <tr rel="flat"> <td class="question"><label for="flat"><span class="accessibility">If metal:</span>Question #2</label></td> <td><input type="radio" name="buttonset2" value="4" rel="uneven" id="r4" /> <label for="r4">Yes</label><br /> <input type="radio" name="buttonset2" value="5" rel="none" id="r5" /> <label for="r5">No</label><br /> </td> </tr> Is it possible to switch out the alerts for yes and no for next 4 questions? And finally, the following is the lengthy, thorough version of my question if it clarifies what I'm trying to do. I would really appreciate someone to point me the right direction. I've tried all kinds of variation to the script and I just can't seem to make it work. Thanks in advance! (Lengthy Version) I also need questions to appear (or not show) below as select radio buttons are clicked. I have 6 groups of yes and no radio buttons. I would like the first two groups to have "alert 1" when yes is clicked (and "alert 2" for no.) I would like the rest to show "alert 2" when yes is clicked (and "alert 1" for no.) (I also have all the questions hidden below question 1. Each subsequent questions appear upon clicking yes for questions 1&2, and no for the rest. I would like to keep this intact - I put that js code I downloaded at the end of this post.) Here's what I have so far... I got most of it working except after the first question, "alert 1" appears for all the clicks submitted. I've been at it for a few weeks and I can't seem to figure it out. Thanks in advance!

Thanks in advance 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;}
}
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; }
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 All. What my script does is if you do not select a radio button and you hit submit an error will pop up saying please select game1. this is taken from the name of the radio button.. How can i make it so it prints out the VALUES of the 2 radio buttons. end result should print please select Baltimore Ravens vs. Cincinnati Bengals rather than please select game1. Code: function isChecked(radgrp)
{
var i = radgrp.length;
do
if (radgrp[--i].checked)
return true;
while (i);
return false;
}
function validateTest(els)
{
var focus_me = null, msg = "";
if (!isChecked(els.game1))
{
msg += " Game #1\n";
focus_me = focus_me || els.game1[0];
}
if (!isChecked(els.game2))
{
msg += " Game #2\n";
focus_me = focus_me || els.game2[0];
}
if (!isChecked(els.game16))
{
msg += " Game #16\n";
focus_me = focus_me || els.game16[0];
}
if (msg != "")
{
var prefix = "\n WARNING: The following Games(s) were not selected:\n\n";
var suffix = "\nClick OK to submit your picks anyway.\n\n";
var suffix = suffix + "\n Click CANCEL to correct your picks."
var ask = confirm(prefix + msg + suffix);
if (ask) {
if (focus_me)
focus_me.focus();
return true;
}
else{
return false;
}
}
}
Here is the radio button. If you dont select the radio button i want the javascript validation pop but to say "please select Baltimore Ravens vs. Cincinnati Bengals rather than game1 like it does now. Code: <INPUT TYPE=RADIO NAME="game1" VALUE="Baltimore Ravens">Baltimore Ravens<BR> <INPUT TYPE=RADIO NAME="game1" VALUE="Cincinnati Bengals">Cincinnati Bengals<BR> Thanks I am using ASP validators and I have a contact form. I want to be able to have a phone and email radio button group. The email textbox also has a RegularExpressionValidator If the phone item is selected then I want the validation to be enabled on the phone text box making it mandatory while the email text box isn't, and if they choose the email as the contact it will be reversed. I want to be able to do this without having to do a postback. I already have the logic on the code behind and the enquiry object. also I am fairly new to javascript so I have been using mostly jQuery as easier to implement here is the html code that i have PHP Code: <td valign="middle" valign="middle"> <input type="radio" name="gender" id="genderM" value="Male" /> Male <input type="radio" name="gender" id="genderFM" value="Female" /> Female </td> and here is the js funtion PHP Code: var $j = jQuery.noConflict(); function isValidEmail(str) { return (str.indexOf(".") > 2) && (str.indexOf("@") > 0); } function validateForm(){ var firstName; var lastName; var email; var mobile; var comment; var error; firstName = $j('#firstName').val(); lastName = $j('#lastName').val(); email = $j('#email').val(); mobile = $j('#mobile').val(); comment = $j('#comment').val(); if(firstName=='' || firstName.length < 3){ error = 'Please Enter Your First Name'; $j('#errormsg').html('<p class="errors">'+ error +'</p>'); return false; } if(lastName=='' || lastName.length < 3){ error = 'Please Enter Your Second Name'; $j('#errormsg').html('<p class="errors">'+ error +'</p>'); return false; } //mob //$jmob_pattern = '^\d{10}$j'; if(mobile.length != 10 || isNaN(mobile)){ error = 'Please Enter Your Mobile Number'; $j('#errormsg').html('<p class="errors">'+ error +'</p>'); return false; } if(email=='' || !isValidEmail(email)){ error = 'Please Enter Your Email Address'; $j('#errormsg').html('<p class="errors">'+ error +'</p>'); return false; } if(comment.length < 5){ error = 'Please Enter A Comment'; $j('#errormsg').html('<p class="errors">'+ error +'</p>'); return false; } return true; } Does anybody know how i check to see if the radio button is select and also can anybody tell me how i can check for an email in the correct format the function isValidEmail in the above alows emails to pass through if they are in this format aaa@aaa. i only want them to go through if they are aaa@aaa.com Thanks for your help if you give it I have three radio button groups with different values. My script only works for one group. Please help! <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script> function emailTo(){ var emails = document.getElementsByName("email1"); var emailAdress = null; for(var i = 0; i < emails.length; i++){ if(emails[i].checked){ emailAdress = emails[i].value; } } if(emailAdress == null){ alert("select the email address"); return; } var mailto_link = 'mailto:'+emailAdress; var win = window.open(mailto_link,'emailWindow'); if (win && win.open &&!win.closed) win.close(); } </script> </head> <body> <p> <input type = "radio" name = "email1" value = "email1.com"/> recipient 1a <input type = "radio" name = "email1" value = "email1.com"> recipient 1b </p> <p> <input type = "radio" name = "email2" value = "email2.com"/> recipient 2a <input type = "radio" name = "email2" value = "email2.com"> recipient 2b</p> <p> <input type = "radio" name = "email3" value = "email3.com"/> recipient 3a <input type = "radio" name = "email3" value = "email3.com"> recipient 3b</p> <p> </p> <p> <input type = "button" onClick = "emailTo()" value = "Email"/> </p> </body> </html> I need a script that will allow a user to select a vertical selection and Horizontal selection that displays a corresponding image. There are only 8 combinations (4 vertical choices and 2 horizontal choices) I just need to display the correct image and a description. There has to be only one of each selected and only display one image. I have tried several and have had no luck. Any ideas? Here is how the layout will look 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 wrote a function to to validate some elements in my form and for some reason I can't seem to figure out why my radio validation is not working. There are about 3 to 4 radio buttons. all with the same name, but i need to make sure that at least one out of this group is selected. Below is my code. Any help would be very useful. Thanks!

everything works up until the if(uscan == "n") so idk why it cant find what the value of the field is, because ive tested it and it seems to know even know what the value is. anything im doing wrong? Hi, I am using a script called osDate and I am trying to modify the sign up form to suit my setup.

I have attached an image showing sample scenario with this post. If someone has an Idea how to to do please sail me thru. Hi guys, I am working on my first validation form and although the Submit button works fine and puts me to the landing page, I don't get the alert, when nothing is checked. Please look at my code and help if you can.

I really need it asap... thanks guys, you're awesome 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>
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. |
