JavaScript - Copy Data Between Form Fields

I need help in a form so that a radio button input sets 2 NAME values like NAME="name1" and NAME="name2"

Since I don't think this is possible, I would by happy to copy the value of name1 to name2 via a script/vb/java, etc.

Here's the code snippet I have that needs help.

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="business" value="99999999999">

<table border="0">
<tr><td><input type="radio" name="name1" value="25.00">Donate $25
<tr><td><input type="radio" name="name1" value="90.00">Donate $90
<td><td><input type="radio" name="name1" value="Other">Other Amount</td><td>
<td>$</td><td><input type="text" name="name1">
</table>


[Now, I need code to auto set NAME="name2" to always be the same value as "name1" above even if user re-selects choice]

Thanks Dave

Hi,
I have a working contact form with 3 of the fields requiring validation and they work well.
I have added extra fields to the form (StatusClass, Project, CameFrom). These 3 fields return fine but I need to validated them.
My problem is that the new fields don't show in the behaviours/validate panel even though they are within the form tag.
Can anyone give me any help and advice as to how to accomplish this?
Many thanks
Code below....

Code:

<script type="text/JavaScript">
<!--
function MM_findObj(n, d) { //v4.01
  var p,i,x;  if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
    d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
  if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
  for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
  if(!x && d.getElementById) x=d.getElementById(n); return x;
}

function MM_validateForm() { //v4.0
  var i,p,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;
  for (i=0; i<(args.length-2); i+=3) { test=args[i+2]; val=MM_findObj(args[i]);
    if (val) { nm=val.name; if ((val=val.value)!="") {
      if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');
        if (p<1 || p==(val.length-1)) errors+='- '+nm+' must contain an e-mail address.\n';
      } else if (test!='R') { num = parseFloat(val);
        if (isNaN(val)) errors+='- '+nm+' must contain a number.\n';
        if (test.indexOf('inRange') != -1) { p=test.indexOf(':');
          min=test.substring(8,p); max=test.substring(p+1);
          if (num<min || max<num) errors+='- '+nm+' must contain a number between '+min+' and '+max+'.\n';
    } } } else if (test.charAt(0) == 'R') errors += '- '+nm+' is required.\n'; }
  } if (errors) alert('The following error(s) occurred:\n'+errors);
  document.MM_returnValue = (errors == '');

I have here a code that will automatically generate two text fields (Title & Price) when "Add another article" is pressed. I got this from the web, but I want instead of using a text field, I want it to create a drop down menu based on a mysql table, then update the price automatically (also based on the mysql table) on the other text field once a selection has been made on the drop down menu.

Code:

<link rel="stylesheet" type="text/css" media="screen" />
        <style type="text/css"></style>
        <script type="text/javascript">
            var elCount = 2;
            function add() {
                var parent = document.getElementById('parent');
                var article = document.createElement('DIV');
                article.id = 'article_' + elCount;
                article.name = 'article_' + elCount;                                     // NEW LINE
                var article_title_label = document.createElement('LABEL');
                article_title_label.appendChild(document.createTextNode('Title ' + elCount + ': '));
                var article_title_text = document.createElement('INPUT');
                article_title_text.id = 'article_' + elCount + '_title';
                article_title_text.name = 'article_' + elCount + '_title';                // NEW LINE
                var article_textarea_label = document.createElement('LABEL');
                article_textarea_label.appendChild(document.createTextNode('Price ' + elCount + ': '));
                var article_textarea = document.createElement('INPUT');
                article_textarea.id = 'article_' + elCount + '_price';
                article_textarea.name = 'article_' + elCount + '_price';                // NEW LINE
                article.appendChild(article_title_label);
                article.appendChild(article_title_text);
                article.appendChild(article_textarea_label);
                article.appendChild(article_textarea);
                parent.appendChild(article);
                elCount++;
            }
        </script>
<body>
                  <div id="parent">
                        <div id="article_1">
                            <label for="article_1_title">Title 1: </label><input type="text" name="article_1_title" id="article_1_title" />
                            <label for="article_1_price">Price: </label><input type="text" name="article_1_price" id="article_1_price" />
                       </div>
                  </div>

any ideas? Thanks

I am no javascript expert, very much a beginner. I am trying to incorporate some into a web-based form. The problem is the button I created to add extra fields does not work, and I can't find exactly where the problem is. I'm in need of some help from a javascript guru. Help me enjoy my Friday afternoon by solving this!

The javascript is mostly borrowed and slightly altered, the "additem" I wrote myself so that is probably where the problem lies!

Here is the html:


Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=iso-8859-1"/>
<title></title>
<link rel="shortcut icon" href="favicon.ico" type="image/x-icon"/>
<link rel="stylesheet" type="text/css" href="style.css"/>

<script type="text/javascript">



function showAsset(id,str)
{
if (str=="")
  {
  document.getElementById("assetinfo"+id).innerHTML="";
  return;
  } 
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("assetinfo"+id).innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","getasset.php?q="+str,true);
xmlhttp.send();
}

var noFields = "5";

function additem()
	{
		var fieldrow = document.createElement('tr');
		var fieldcolumn1 = document.createElement('td');
		var fieldinput = document.createElement('input');
		fieldinput.name = "asset";
		fieldinput.onChange = "showAsset("+noFields+",this.value)";
		var fieldcolumn2 = document.createElement('td');
		fieldcolumn2.id = "assetinfo"+noFields;
		fieldcolumn1.appendChild(fieldinput);
		
		var fieldcolumns = fieldcolumn1 + fieldcolumn2;
		fieldrow.appendChild(fieldcolumns);
		
		var addbefore = document.getElementById('fieldend');
		document.body.insertBefore(fieldrow, addbefore);
		noFields = noFields++;
	}
</script>

</head>
<body>

<form>
	<table>
		<tr>
			<td><input name="asset" onChange="showAsset(1,this.value)"></td>
			<td id="assetinfo1"></td>
		</tr>
		<tr>
			<td><input name="asset" onChange="showAsset(2,this.value)"></td>
			<td id="assetinfo2"></td>
		</tr>
		<tr>
			<td><input name="asset" onChange="showAsset(3,this.value)"></td>
			<td id="assetinfo3"></td>
		</tr>
		<tr>
			<td><input name="asset" onChange="showAsset(4,this.value)"></td>
			<td id="assetinfo4"></td>
		</tr>
		<tr>
			<td><input name="asset" onChange="showAsset(5,this.value)"></td>
			<td id="assetinfo5"></td>
		</tr>
		<tr id="fieldend">
			<td><input id="addfield" type="button" value="add item" onClick="addfield()"></td>
		</tr>
</table>

</form>

</body>
</html>

Here is the associated getasset.php:

Code:

<?php
$q=$_GET["q"];

$con = mysql_connect('localhost', 'root', 'root');
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("assettracking", $con);

$sql="SELECT * FROM assets WHERE assetID = '".$q."'";

$result = mysql_query($sql);


while($row = mysql_fetch_array($result))
	{
	echo "<b>".$row['make'] ." ".$row['model'] ." - ".$row['serialnumber']."</b> | Status: ".$row['statusID']." | Comments: ".$row['comments'];
	}
	
mysql_close($con);
?>

Hi, i have this code that generate 10 rows with form fields:

Code:

<form>
<?php for($i=1;$i<=10;$i++) {?>
<div id="rowz-rep">
<div class="row1"><?=$i?></div>
<div class="row2a"><input name="title[]" type="text" class="fieldSubmit"/></div>
<div class="row3a"><input name="url[]" type="text" class="fieldSubmit"/></div>
<div class="row4a"><select name="type[]" class="dropSubmit"><? foreach($allowed_types as $at) { echo '<option value="'.$at.'">'.$at.'</option>'; }?></select></div>
</div>
<? }?>
</form>

I need that onclick with JS add 10 more rows so i get something like

Code:

<?php for($i=1;$i<=20;$i++) {?>

Hi all, I'm new to here and JS but I have question for you! So I have this form with inputs that are considered arrays in my PHP code:

Code:

<input type="checkbox" name="1" /> <input name="i[]" type="text"> <br /> 
<input type="checkbox" name="2" /> <input name="i[]" type="text"> <br /> 
<input type="checkbox" name="3" /> <input name="i[]" type="text"> <br /> 
<input type="checkbox" name="4" /> <input name="i[]" type="text"> <br /> 
<input type="checkbox" name="5" /> <input name="i[]" type="text"> <br /> 
<input type="checkbox" name="6" /> <input name="i[]" type="text"> <br /> 
<input type="checkbox" name="7" /> <input name="i[]" type="text"> <br /> 
<input type="checkbox" name="8" /> <input name="i[]" type="text"> <br /> 
<input type="checkbox" name="9" /> <input name="i[]" type="text"> <br /> 
<input type="checkbox" name="10" /> <input name="i[]" type="text"> <br /> 
<input type="checkbox" name="11" /> <input name="i[]" type="text"> <br />

<input type="checkbox" name="19" /> <input name="i[]" type="text"> <br /> 
<input type="checkbox" name="20" /> <input name="i[]" type="text"> <br />

I don't want to keep adding in new spots every time a user want to add a new field. I would like them to be able to press a button that will add another one of those fields and so on. I'm not sure how this can be achieved but that's why I am turning to you! Thanks!

Here's what I have so far in my validation part.

However, I need help as to how to validate the following fields when the user clicks the submit button.
-Radio Button
*title (4 options)
*member (3 options)
*vegetarian (2 options)

-Drop down lists
*regstartdate (3 options)
*regenddate (3 options)
*confdinner (2 options)
*paymethod (3 options)


-UK Post Code (text box with maxlength=8)


My current code shows 1 popup with all the error messages. Here's what I have so far:

Hi guys, I created a form that contains about 10 form fields and would like to add the option to dynamically add more sets of those 10 fields if a user clicks a word or a button but I need help. I'm a beginner when it comes to JavaScript and would appreciate any help. This is what I need to generate dynamically. Can someone give me an idea of how to get started please?

Code:

<div id="dynamicInput">
<ul>
<li>1</li>
<li><input name='textfield1' type='text' size='10' /></li>
<li><select name='commodity' width='100' style='width: 100px'>
<option>Option 1</option>
</select></li>
<li><input name='textfield2' type='text' size='5' /></li>
<li><input name='textfield3' type='text' size='10' /></li>
<li><input name='textfield4' type='text' size='10' /></li>
<li><input name='textfield5' type='text' size='10' /></li>
<li><input name='textfield6' type='text' size='5' /></li>
<li><input name='textfield7' type='text' size='5' /></li>
<li><input name='textfield8' type='text' size='5' /></li>
</ul>
</div>

I have two slightly different forms on the same page, but I want the values in form1 to auto populate the same form fields in form2. 1 field is a text field, the rest are drop down menus. How would I accomplish this? Link to tutorial would be much appreciated. Thanks

So, I'm trying to make a function that marks a specific form field if it triggers an error when the form submits. Doesn't seem to work, though. The function to mark the form field resides in a .js file separate from the function that validates the form. Not sure if that matters, but thought I'd post it here just to be sure. Here's the code for the field marking script:

Code:

function markFormField(fieldInError)
{

   // start by changing its background color
   
   fieldInError.style.backgroundColor = "#FF99FF";
   
   // check the parent tag to make sure it's a label
   
   if (fieldInError.parentNode.tagName == "LABEL")
   {
   
      // if it is, change the font color
      
      fieldInError.parentNode.style.color = "#FF0000";
      
   }
   
}

Here's the code that validates the form:
Code:

function checkNewsInput()
{

   // see if the DOM can be used
   
   if (!document.getElementById)
      return;
      
   // otherwise, set up the variables
   
   var newsCat = document.getElementById("category");
   var newsTitle = document.getElementById("title");
   var newsBody = document.getElementById("body");
   var newsDesc = document.getElementById("desc");
   var newsTags = document.getElementById("tags");
   var newsInfo = document.getElementById("info");
   var newsPwd = document.getElementById("pwd");

   /* NOTE: cursorToEnd is a function I got from a helpful member of this
       forum. Its code is not listed in this post. */
   
   if (newsCat.value == "")
   {
   
      window.alert("Please select a category.");
      
      return false;
      
      markFormField(newsCat);
      
   }
   
   else if (newsTitle.value.length < 5 || newsTitle.value == "")
   {
   
      window.alert("The title must be at least 5 characters in length.");
      
      return false;
      
      markFormField(newsTitle);
      
      cursorToEnd(newsTitle);
      
   }
   
   else if (newsBody.value.length < 10 || newsBody.value == "")
   {
   
      window.alert("The body of the post must be at least 10 characters in length.");
      
      return false;
      
      markFormField(newsBody);
      
      cursorToEnd(newsBody);
      
   }
   
   else if (newsDesc.value.length < 10 || newsDesc.value == "")
   {
   
      window.alert("The description must be at least 10 characters in length.");
      
      return false;
      
      markFormField(newsDesc);
      
      cursorToEnd(newsDesc);
      
   }
   
   else if (newsTags.value.length < 5 || newsTags.value == "")
   {
   
      window.alert("The tags field must be at least 5 characters in length.");
      
      return false;
      
      markFormField(newsTags);
      
      cursorToEnd(newsTags);
      
   }
   
   else if (newsInfo.value.length < 10 || newsInfo.value == "")
   {
   
      window.alert("The info must be at least 10 characters in length.");
      
      return false;
      
      markFormField(newsInfo);
      
      cursorToEnd(newsInfo);
      
   }
   
   else if (newsPwd.value == "")
   {
   
      window.alert("Please enter your password.");
      
      return false;
      
      markFormField(newsPwd);
      
      cursorToEnd(newsPwd);
      
   }
   
   else
   {
   
      // all is good, so let the form submit
     
      return true;
     
   }
   
}

This is what I'm trying to do.

If a person selects a Friday Class but not a Saturday Class the Total Cost Field will automatically enter $99.

If a person selects a Saturday Class but not a Friday Class the Total Cost Field will automatically enter $99 as well.

If a person selects both a Friday & Saturday Class the Total Cost field will automatically be $159.

I found the following code and so far only have it changing when a Friday class is entered. I have no idea where to go from here. Please help.


Code:

Greetings experts, this is my first time here.

So, please take easy on me.

I have makup with 2 sections.

The first section contains 5 form fields and are required.

The second second has 2 form fields and are optional.

Users can only choose from one section or the other but not both.

The js script below ensures that if users select from section 2, section one will not challenge for validation and works a treat.

The challenge I have now is to ensure that if users choose from section 1, the 2 form fields in section are automatically disabled so they won't be attempted to choose from it.

Similarly, if users select from section 2, all form fields in section one are automatically disabled so they won't be tempted to choose from that section.

Is this possible?

If not possible, is it possible to raise an error?

For instance, a user selects from section 1 and attempts to select from any of the 2 form fields in section 2, a message that says, "You can only select from one section but from both.

Similarly if a user selects from section 2 first, same thing happens.

Thanks very much for your assistance.

function validate() {

if(document.getElementById("<%=txtrequest.ClientID%>").value != "" &&
document.getElementById("<%=txtreceived.ClientID %>").value != "")
{
if (document.getElementById("<%=txtName.ClientID%>").value == "") {
alert("Please enter name");
document.getElementById("<%=txtName.ClientID%>").focus();
return false;
}

if (document.getElementById("<%=txtCity.ClientID %>").value == "") {
alert("Please enter city");
document.getElementById("<%=txtCity.ClientID %>").focus();
return false;
}
if (document.getElementById("<%=txtState.ClientID%>").value == "") {
alert("Please enter state");
document.getElementById("<%=txtState.ClientID%>").focus();
return false;
}
if (document.getElementById("<%=txtZip.ClientID%>").value == "") {
alert("Please enter zip");
document.getElementById("<%=txtZip.ClientID%>").focus();
return false;
}
if (checkradio() == false) {
alert("Please enter contacts");
document.getElementById("<%=txtContacts.ClientID%>").focus();
return false;
}
}
return true;
}

I'm trying to make a site where when you click the submit button it puts an asterisk next to all of the incomplete fields while also displaying an alert box.

I'm having no luck with it so far since I don't know how to get a script to print something to a specific part of a page.

Here is what the whole thing looks like so far. I tried using page-jumping but that didn't work:
Code:

<html>
<head>
<title>Sortomatic 5000 </title>

<script type="text/javascript">
function Sort(form){
	var fruits = [form.One.value, form.Two.value, form.Three.value];
	if (form.One.value!=""&&form.Two.value!=""&&form.Three.value!=""){
		document.writeln(fruits.sort());
	}
	if(form.One.value=""){
		alert("Please enter at least one character into all fields.");
		parent.location='#first';
		document.writeln("*");
	}
	if(form.Two.value=""){
		alert("Please enter at least one character into all fields.");
		
	}
	else{
	alert("Please enter at least one character into all fields.");
	
	}

}
</script>
</head>
<body>
<form name="Sortform" > 
<input type="text" name="One"><A NAME="first"></A><br>
<input type="text" name="Two"><br><A NAME="second"></A>
<input type="text" name="Three"><br><A NAME="third"></A>
<input type="submit" onClick="Sort(this.form)">
</form>
</body>

</html>
