JavaScript - Displaying Results Based On Radio Button Selection Without A Browser Refresh
I am very inexperienced with javasciprt. I am designing a form in coldfusion, and want some dynamic action to take place.
My users will be offered 2 selections via radio buttons. Depending on which radio button they select, they will get a few more radio buttons to choose from. I have been told that this can be handled in javascript. So I am appealing to the javascript programmer nation for some assistance in this endeavor. Any help would be greatly appreciated, Thanks. Similar Tutorialsform is .asp scenario: I have 3 radio buttons above number of boxes (dropdown). I want the dropdown selection box greyed out on selecting Electronic (radio button) Physical (radio button) Image (radio button) Electronic (radio button) Number of Boxes [dropdown box] Thanks for your help I am new to coding. 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 Codes for Dropdown menu based on radio buttons selection needed!? I need urgent help with this: I need codes for a dropdown menu that is altered by radio buttons. I want to insert the value selected from the dropdown menu into a table. 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: </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: </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. I've got a function that returns the value of a radio button group. However the application allows to "hide" some groups on others responses and that effectively make the radio groups not exist. This causes issues with calculations using the total value of the groups combined. I need a way to return a value of '0.00' IF the function does not find the group/returns an error.This is what I currently got to but doesnt work. The function does not work at all. Code: function funcRadioCalc(RadioName)
{
var chkList1= document.getElementById (RadioName);
var arrayOfCheckBoxes= chkList1.getElementsByTagName("input");
var bob;
try {
for( var i=0;i<arrayOfCheckBoxes.length;i++){
if (arrayOfCheckBoxes[i].checked) {
bob= arrayOfCheckBoxes[i].value;
if (bob!=undefined||bob!=""){
throw "yep";
}else{
throw "nope";
}
}
}
catch (er){
if(er=="nope")
{
return "0.00";
}
if(er=="yep")
{
return bob;
}
}
}
Dear Javascript programmers, Do you have an example of a Javascript something like this: A dropdownlist with values "one" and "two". The radio button is not visible (as a start). - If you have selected "one" from the dropdown list, then a radio button will appear. - If you have selected "two" from the dropdown list, then a radio button will NOT appear. Thanks, Cornelis Gouda - The Netherlands How can I hide/disable the submit button if the name Todd is selected? Code: <html> <head> </head> <body> <form name="people"> <select name="group"> <option value="Pick Your Name">Choose</option> <option value="Tom">Tom</option> <option value="Freddy">Freddy</option> <option value="Todd">Todd</option> <option value="Fred">Fred</option> <option value="William">William</option> <option value="Johnson">Johnson</option> </select> <INPUT TYPE=submit VALUE="submit"> </form> </body> </html> I would like to display one of two different <div> tags based on a radio button. In essence, this would be the "basic" and "advanced" options as the user end. Can this be done easily or will it be complex? Hi i have 2 radios : what i need is once i choose the 1st radio i will get 1st DDL with folollwing element : Orange Apple Kiwi if i chose the 2nd radio i should have the 2nd DDL with : Potato Tomato legume ? thanks I am a complete JS noob. I have been googling for hours trying to find a way to implement what I think is a simple thing - but alas my deadline is here, and I need to solve this and seek guidance from courteous experts! In a nutshell I have a simple form that has radio buttons: Code: <p><input id="amount" name="amount" type="radio" value="125" />$125</p> <p><input id="amount" name="amount" type="radio" value="75" />$75</p> <p><input id="amount" name="amount" type="radio" value="50" />$50</p> <p><input id="amount" name="amount" type="radio" value="25" />$25</p> <p><input id="amount" name="amount" type="radio" value="other" /><input id="other_amount" name="other_amount" type="text" maxlength="7" style="width:100px;" /> Other ($10 minimum donation)</p> The point of the form is to assign the value to "amount" for sending on to a paypal form. The problem is, I need the value of "amount" to change (be assigned) if they chose "other". To take the value from the text input box "other_amount" and assign it to "amount" but only if they chose the 5th radio button. I have some JS that I hacked together that checks to see if they chose the 5th radio button. attempts to assign the "other amount" to "amount" and then pops up an alert (only so I know the script is pushing the right value - wont be needed when complete.) However, Even though the alert pops up with the proper "other_amount" as if it has been assigned properly, the data is not sent on properly I presume, as it is the only aspect of the paypal donation amount form that is not working or providing the next page with the right "amount" pre-determined. Code: <script type="text/javascript">
<!--
function get_radio_value()
{
if (document.donation.amount[4].checked)
{
document.getElementById('amount').value = document.donation.other_amount.value;
alert(document.getElementById('amount').value);
}
}
//-->
</script>
Help please! Many thanks in advance! Deadline agh! Hello, I need some script to force the browser to reload/refresh when a page is reached from the back button. EG You're on page A -> You click a link onto page B -> You Press Browser back to go onto Page A, it has old content that requires a reload. Now, my page is currently php so I won't bother with my code here as I am looking for any solution (I have also posted in php forum). Any JS solution that will trigger a reload on browser back is appreciated. I have tried a few ideas, most work in Chrome, IE always works, Firefox 4 and Opera 11 wont reload, simply fetching from cache I believe. Thanks. Hi Everyone, I want to create some web pages in asp.net on which I want to avoid the user to refresh the page. I have disabled the refresh options using key board event which are as follows: 1) F5 2) Ctrl + F5 3) Ctrl + R But I want to avoid user clicking on the Refresh Button of the browser. So please help me how can we disable the Browser Refresh button/menu using Javascript ? Thanks & regards, Anthony D'souza. Hi Guys, I'm fairly new to Javascript and would be grateful for any help you can give me. 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" /> I have a radio button that asks Does your URL exist or need to be purchased? and a drop down menu that lists different types of web projects (i.e. new website and website redesign). What I'm trying to achieve is, if the user selects that the URL exists, I would like the drop down menu option new website to be removed from the list. Form: Code: <form> <input type="radio" name="website_status" value="exists"/> Exists <input type="radio" name="website_status" value="purchase_required"/> Needs to be purchased <select name="projects"> <option></option> <option value="new_website">New Website</option> <option value="website_redesign">Website Redesign</option> </select> </form> JavaScript: [CODE] <script> window.onload = initForms; function initForms() { for (var i=0; i<document.forms.length; i++) { document.forms[i].onsubmit = function() {return validForm();} } } function validForm() { var inputarray = document.getElementsByTagName("input"); var selectarray = document.getElementsByTagName("select"); var textarea = document.getElementsByTagName("textarea"); if (inputarray[0].checked == true) { selectarray[0].remove(options[1]); return false; } </script> I've been experimenting with this for the last couple hours and am getting nothing! Could someone please point me in the right direction? I have been searching for a way to display facebook api friends.getAppUsers in set of 5. I am able to do this if i hard code it but I cant seem to find and comprehend a method to do this dynamically. What i want to achieve is, if i have 43 friends using the application, the code should allow users to view this result in set of 5. -prevBtn- friend1 friend2 friend3 friend4 friend5 -nextBtn- upon clicking on the nextBtn, -prevBtn- friend6 friend7 friend8 friend9 friend10 -nextBtn- etc i am actually relatively new to Javascript and Facebook Codings.. so any help would really be great!

hello im attempting to display the output of the radio selection into the textbox. For example, if the user selects 0-15 then display "Your age group is 0-15 years" in the text area. i get the basic logic. i just dont understand how to display the value in the textbox. heres what i have so far if it will clarify my issue. Code: <html>
<head>
<title>lab 8</title>
<script language="javascript">
function textbox()
{
var i;
for(i = 0; i < form1.agegroup.length; i++)
{
if (form1.agegroup[i].checked)
alert("you picked " + form1.agegroup[i].value);
}
}
</script>
</head>
<body>
What is your age group?<br>
<form name="form1">
<input type="radio" name="agegroup" value="0-15" checked>0-15<br>
<input type="radio" name="agegroup" value="16 to 20">16 to 20<br>
<input type="radio" name="agegroup" value="21 to 25">21 to 25<br>
<input type="radio" name="agegroup" value="26 to 35">26 to 3<br>
<input type="radio" name="agegroup" value="36 and up">36 and up<br>
<input type="button" value="submit" onclick="textbox();">
<form name="form2"><textarea rows ="2">
</textarea>
</body>
</html>
btw i know the alert part is wrong. its there because im taking the code i previously had and changing it to display in a textbox instead of an alert. thanks I want to insert text to a textarea based on the selected text. It should insert tags like the buttons for posting on this form work. Ie: If 'bar' is selected, and I click 'b', then I get: Code: Foo bar frog becomes: Code: Foo <b>bar</b> frog I found some code that works for firefox, but I need it to work in explorer as well. Do you have any ideas or examples how to do this? Here's the code I'm currently using. ( Works right in ff3. In IE7 it appends the tags at the end of the text. I want it to insert based on my selection. ) Usage: Code: <a onclick="insertTags('<b>', '</b>', document.forms.formpost.text);return false;" href="javascript:void(0);">[ Bold ]</a>
insert function: Code: <script type="text/javascript">
// Surrounds the selected text with text1 and text2.
function insertTags(text1, text2, textarea)
{
// Can a text range be created?
if (typeof(textarea.caretPos) != "undefined" && textarea.createTextRange)
{
var caretPos = textarea.caretPos, temp_length = caretPos.text.length;
caretPos.text = caretPos.text.charAt(caretPos.text.length - 1) == ' ' ? text1 + caretPos.text + text2 + ' ' : text1 + caretPos.text + text2;
if (temp_length == 0)
{
caretPos.moveStart("character", -text2.length);
caretPos.moveEnd("character", -text2.length);
caretPos.select();
}
else
textarea.focus(caretPos);
}
// Mozilla text range wrap.
else if (typeof(textarea.selectionStart) != "undefined")
{
var begin = textarea.value.substr(0, textarea.selectionStart);
var selection = textarea.value.substr(textarea.selectionStart, textarea.selectionEnd - textarea.selectionStart);
var end = textarea.value.substr(textarea.selectionEnd);
var newCursorPos = textarea.selectionStart;
var scrollPos = textarea.scrollTop;
textarea.value = begin + text1 + selection + text2 + end;
if (textarea.setSelectionRange)
{
if (selection.length == 0)
textarea.setSelectionRange(newCursorPos + text1.length, newCursorPos + text1.length);
else
textarea.setSelectionRange(newCursorPos, newCursorPos + text1.length + selection.length + text2.length);
textarea.focus();
}
textarea.scrollTop = scrollPos;
}
// Just put them on the end, then.
else
{
textarea.value += text1 + text2;
textarea.focus(textarea.value.length - 1);
}
}

Hey everyone, I have a simple html form that asks a user to select a state from a drop down list. Later, in the same form, there's a question that needs to display an image of the state they previously selected from the drop down menu. How can I accomplish this using javaScript?
Hi Guys, I'm a new member, so hello all! I'm ok at html/xhtml, but i know nothing about javascript, so hoping someone here can help! Basically, I have a contact form on my website that offers 2 different types of contact: RSVP and Other. these two types are available in a selection box. What I want to happen is when the "RSVP" option is selected, the following options are displayed: "Yes/No" radio buttons "additional info" textarea And when the "Other" option is selected, the following option is displayed: "Message" text area How can i make this happen?! i've tried searching the internet but I can't get anything i find to work. I can't even get the elements to hide! At the moment, my form looks like this: - Code: <form method="POST" action="contact.php"> <table class="contact"> <tr> <td>Name:</td> <td><input type="text" name="name" size="20"></td> </tr> <tr> <td>Email:</td> <td><input type="text" name="email" size="20"></td> </tr> <tr> <td>Contact Type:</td> <td><select size="1" name="type"> <option value="rsvp" >RSVP</option> <option value="other">Other</option></td> </tr> <tr> <td colspan=2> </td> </tr> <div id="rsvp" style="display:none;"> <tr> <td colspan=2><input type="radio" name="response" value="y"> Yes Please!</td> </tr> <tr> <td colspan=2><input type="radio" name="response" value="n"> Sorry, but No. </td> </tr> <tr> <td colspan=2>Additional Comments (Please include any special dietary requirements): </td> </tr> <tr> <td colspan=2><textarea rows="5" name="rsvpmsg" cols="30"></textarea></td> </tr> </div> <div id="other" style="display:none;"> <tr> <td colspan=2>Message:</td> </tr> <tr> <td colspan=2><textarea rows="9" name="othermsg" cols="30"></textarea></td> </tr> </div> <tr> <td> </td> <td><input type="submit" value="Submit" name="submit"> <input type="reset" value="Reset" name="reset"></td> </tr> </table> </form> Please note, the style="display:none;" parts aren't even working I appreciate any help you can give! thanks! I'm trying to write a progressively enhanced web application. I have an index page and a form with some select boxes and some radio buttons on a different php page. Before enhancement occurs, the form is accessible via regular links and everything works as expected. No issues. In the enhanced version of the application, the form is AJAXed into the index page. When this occurs, the select boxes in the form work perfectly. The radio buttons are initially unchecked and I can check one option as usual. However, once one is checked, clicking the other radio options does nothing. I am unable to check a different option. Anybody got a clue what the problem is? Using Chrome by the way. Firefox is the same as Chrome. In IE I can't even check a radio button the first time. Here's the code that's ajaxed in: Code: <label>First Time Buyer Status <!--These values can't be 1/0 because 0 stands for not set--> <input type="radio" name="FTB" id="FTBYes" value="1" <?php $M->checkFTBValue(1); ?> title=""/>First Time Buyer <input type="radio" name="FTB" id="FTBNo" value="2" <?php $M->checkFTBValue(2); ?> title=""/>Not First Time Buyer </label> The PHP script you see there checks if the value on the server matches the value of the radio button and echo's checked="checked" if true. I thought this could be causing the problem initially but the exact same code is used in the non-enhanced version and it works fine. I tried commenting it out anyway but it makes no difference. The only thing I can think of is that some javascript is preventing me from selecting a different radio option. That would explain why it works ok in the non-enhanced version because there is no JS there. I can't find anything that I've written that might cause this effect I'm using jQuerys form plugin on my pages. I'm going to try writing it out and see if that fixes anything. Any body ever experience a similar problem with this? In the mean time, is there a way I can check if any JS functions when I click on the radio button? Sorry if this is in the wrong forum, there's so many different languages involved, I hadn't a clue where to put it. |
