JavaScript - Permanently Selected Radio Button
Greetings Programmers. I'm a graphics artist by trade but I also dabble in web design. I registered to this forum because I need your help.
I've been handed a web project at work - to build an intranet site. My coding skills in HTML are sufficient to get the job done and I can plug in some JS and trobleshoot where needed but I've hit a wall with regard to one seemingly simple piece of code - I can't find a script anywhere that will generate a radio button that will, once selected, stay that way pretty much forever...or until I delete the listing on the page where these buttons will sit. I realize this isn't the concept behind these buttons but I need it to function this way because I'd like it to serve as a quick visual notification that a given employee review has been completed. These reviews will remain online for up to several months because there will be three reviews per employee over the course of that time. The selected buttons will indicate the reviews that are complete while the unselected ones will indicate which ones are still pending. I'd like the various levels of management viewing this information to know instantly, via the buttons, where we are with these reviews. So, that's my question, can a radio button be scripted to stay selected indefinitely once it's been clicked on? Thank you in advance for any help. It's greatly appreciated. - Sgt. Spanky Similar TutorialsHi Experts .. not sure if this is the right forum. However here is my question: I have a date field with 25 values (prepopulated Radio Buttons) where we are asking the members to select one day to volunteer. Once a member selects a day we would like to disable that Radio button value (Greyed out) for other members. So basically out of 25 available days we would like to disable values as soon as a member selects one. The field is on a classic ASP form with SQL Server backend. How can I accomplish the above? Please advice. Regards Vinny Hi, Can somebody help me with the coding. I have a long list of events and I want somebody to be able to select one of those events & there will be a text box that shows the address pertaining to the event selected. Exactly how this website did he http://svacpa.com/live-webinars-and-...-registration/ Please advise!

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 Hey, I need help with a javascript function to show a div when 3 "Yes" radio buttons are clicked.

I'm making a javascript game for a digital media class and I'm having a hard time figuring out how to code this. The idea is that there's three similar images, one that's different and the user must select the image that's different by selecting the radio button below it and pressing the Submit button. So in the if/else statement, I want it to be programmed so that if the correct answer is selected and then submitted, it will take you to another webpage. If an incorrect answer is selected, I want an alert to pop up and say Sorry, that's Incorrect. Here's the coding I have so far, none of which is working. Code: <script type="text/javascript">
function processAnswer()
{
for (i = 0; i <= 3; i++)
{
if (document.myForm.radSize[i].checked == true)
{
size = document.myForm.radSize[i].value;
} // end if
} // end for loop
alert("You Selected a Button")
} // end
</script>
And in the body...
<div id="imagediv"><br /><br /><center>
<form name = "myForm" action="">
<table width="500" border="0">
<tr>
<td><center><img src="images/image2.png" /><br />
<Input type = radio Name = r1 Value = "1" >
</center>
</td>
<td><center><img src="images/image1.png" /><br />
<Input type = radio Name = r1 Value = "2" >
</center>
</td>
<td><center><img src="images/image2.png" /><br />
<Input type = radio Name = r1 Value = "3" >
</center></td>
</tr>
</table><br /><br />
<center><input type = "button"
value = "Submit"
onClick = "processAnswer()"/>
</center>
Any help would be greatly appreciated, I've never worked with javascript before so I'm having a really hard time! I am new to this kind of scripting, so I have not done it before, I have tried to find solutions on the net but none have worked. I have a 'contact us' form, which includes 2 radio buttons to select how they wish to recieve their reply... the first radio is 'email' the second radio is 'phone' When the 'phone' radio is selected, i want the div including a drop downbox to appear to ask what time to recieve a call, but when the 'email' radio is selected, this div does not appear. This is the script for this section. . .. ... <span>Best way to reply:</span> <input type="radio" name="reply" value="Email" id="reply_0" /> E-mail <BR /> <div style="margin-left:270px;"><input type="radio" name="reply" value="Phone" id="reply_1" onclick=""/>Phone</div> <br/> <div id="timehide"><span>Best time to get hold of you:</span> <select> <option value="Any">Any</option> <option value="06:00 - 10:00">06:00 - 10:00</option> <option value="10:00 - 12:00">10:00 - 12:00</option> <option value="12:00 - 14:00">12:00 - 14:00</option> <option value="14:00 - 16:00">14:00 - 16:00</option> <option value="16:00 - 18:00">16:00 - 18:00</option> <option value="18:00 - 20:00">18:00 - 20:00</option> </select></div> ... .. . if anyone could help me it would be greatly appreciated!!!

Cheers, Ben! When a particular radio option is selected and the user presses the submit button, based on what is selected I want a particular lightbox to popup [like an alert]. The JavaScript below is what I used to turn images I created into radio buttons so I could have my own custom styles instead of using the default DOM version. Any help is appreciated.

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>
</form>
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 need to add an alert if the male is not selected in following after clicking on submit button Code: <html><head> </HEAD><BODY> <br><form name="feedback" method=post> Your Gender: <input type="radio" name="gender" value="male" id="male" /> Male <input type="radio" name="gender" value="female" id="female"CHECKED> Female</td> <input type='button' value='Submit' /> </form></BODY></HTML> 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.

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? 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. 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? 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; }
