JavaScript - Quick Radio Button Question

I found this "game" that helps you practice regexp. I'm stuck on this one:

Was wondering if someone could help me quickly, i'm have a strange issue with a slideshow i have built in javascript. The slideshow works fine until you add any other image onto the page like a banner or anything. As soon as you do that when you click next on the slideshow that image or banner with change to the next picture instead of the desired image if that makes any sense...

Would appreciate any help, thank you!

here is the link to my practice website, so you can see what is going on pretty new to all of this..

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&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp</b><input type="Text" name="textGroup1" value="@gmail.com" /> <br/>
</label> 
    <br /> 
    <label> 
<b>friend2&nbsp;&nbsp;&nbsp</b><input type="text" name="textGroup1" value="@gmail.com" /> 
</label> 
    
  </p> 
  
</form>

Here is what i'm trying to do and I'm not sure if it will work with a switch, but i'd be better than writing a million if else statements.

Code:

var = c
var = z

switch (c)
{
case c > 1 && < 10:
z = 5;
break;
case c > 10 && < 20:
z = 15;
break;
default:
z = 0;
}

I think you see what I'm trying to do. I have a variable 'c' and it is input by the user and I want to make variable 'z' set according to what 'c' is. I know the above code doesn't work, but I'm not sure why. I've tried a million different things to try and get it to work, but it always just goes to default when it displays 'z'. Any help would be great. Thanks.

Hey everybody!

I am trying to do a simple echo onclick, but despite what I try to do, it shows no errors, but won't work.

I've tried things like:

Code:

echo "<div onclick=\"alert('test');\">t</div>";
echo '<div onclick="alert(\'test\');">t</div>';

But just can't seem to get it to work right.
I'm trying to do this on a script that is being eval on the ajax request. Thus I'm having problems placing the ',", \ marks. Thanks for your time.

Hi,
Ever seen on the iphone where you have to slide the slider across the screen to unlock it? I have a duplicate of this using javascript but no matter what I try I cannot make it redirect. I want the page to be redirected after the slider has gone to the other side.


Heres the HTML Code:

<!DOCTYPE html>
<head>
	<meta charset='UTF-8'>
	<title>Slide To Unlock</title>
	<link rel='stylesheet' href='css/style.css'>
	<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js'></script>
	<script src='http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.2/jquery-ui.min.js'></script>
	<script src='js/slidetounlock.js'></script>
</head>
<body>
	<div id="page-wrap">
		<div id="well">
			<h2><strong id="slider"></strong> <span>slide to unlock</span></h2>
		</div>
	</div>
</body
</html>

And the javascript
Code:

$(function() {

	$("#slider").draggable({
		axis: 'x',
		containment: 'parent',
		drag: function(event, ui) {
			if (ui.position.left > 550) {
				$("#well").fadeOut();
			} else {
			    // Apparently Safari isn't allowing partial opacity on text with background clip? Not sure.
				// $("h2 span").css("opacity", 100 - (ui.position.left / 5))
			}
		},
		stop: function(event, ui) {
			if (ui.position.left < 551) {
				$(this).animate({
					left: 0
				})
			}
		}
	});
	
	// The following credit: http://www.evanblack.com/blog/touch-slide-to-unlock/
	
	$('#slider')[0].addEventListener('touchmove', function(event) {
	    event.preventDefault();
	    var el = event.target;
	    var touch = event.touches[0];
	    curX = touch.pageX - this.offsetLeft - 73;
	    if(curX <= 0) return;
	    if(curX > 550){
	    	$('#well').fadeOut();
	    }
	   	el.style.webkitTransform = 'translateX(' + curX + 'px)'; 
	}, false);
	
	$('#slider')[0].addEventListener('touchend', function(event) {	
	    this.style.webkitTransition = '-webkit-transform 0.3s ease-in';
	    this.addEventListener( 'webkitTransitionEnd', function( event ) { this.style.webkitTransition = 'none'; }, false );
	    this.style.webkitTransform = 'translateX(0px)';
	}, false);

});

I have a simple issue that I cannot fix.
The code bellow, is a while-loop with RGB color.
It displays the word Hello 10 times id 10 different colors.
The problem is I cannot get the correct colors displayed.
I want the first Hello to be red and end up green in the last one.
For some reason I cannot get the color combination correct, even after I put 255 for red and 192 for green.

Can you please have a look and tell me what am I doing wrong?

Thanks in advance

i have a program where a user enters a temperature in farenheit and the program converts it to celcius.

below is my code:

Code:

<html>
<head>
<title>JavaScript Assignment 4 Part 1</title>



</head>
<body>
<h2>Welcome to the Temperature Calculator!!</h2>

<script type="text/javascript">

var fTemp;
var number1;
var cTemp;



fTemp = window.prompt( "Please enter temperature in Farenheit:", "0" );

number1 = parseInt( fTemp );

cTemp = (5/9) * (number1 - 32);




document.writeln("The corresponding temperature in Celcius is: " + cTemp);


</script>


</body>
</html>

what i cant figure out is how to round off the temperature in celcius so that it doesnt display something like 26.666666666667
i tried putting math.round in
"cTemp = (5/9) * (number1 - 32);"

but when i do my program doesnt work
any advice on how to go about doing this?
thanks

Hi guys, just a quick question about a line break in JavaScript, where would I do it? If you see I have two math operators here and want them to be on two separate lines, were do I put the line break?

Thanks

Code:

<!doctype html>

<head>
</head>
<body>

<script type="text/javascript">
	var apples = 4+76;
	document.write(apples);
	
	var multiple = 54*11;
	document.write(multiple);
</script>


</body>

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:&nbsp;</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:&nbsp;</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 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>
