Here is my validation script from dreamweaver i also have it in php for server side. But I trying to get a checkbox to make a text field required when you select it. Right now I have it so when you hit submit whether the text field is filled out or whether the checkbox is selected or not the error message comes up no matter what i do please help.
the link to the page is http://www.mark-10.com/inquiries2 Code: function validateCheckbox() {
if(document.forms["form1"].sales.checked) {
if(document.forms["form1"].telephone.value.length < 12) { // xxx-xxx-xxxx
return false ;
}
else {
return true;
}
}
}
function MM_validateForm() { //v4.0
if (document.getElementById){
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=document.getElementById(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(!validateCheckbox()) {
errors+="If checkbox checked, please include telephone number";
}
if (errors) alert('The following error(s) occurred:\n'+errors);
document.MM_returnValue = (errors == '');
} }

Similar TutorialsHi, I'm having a problem trying to get my html web form to work. I have a list of 8 radio button options for people to choose one option with the last option being other - and then I want if the user clicks other that the text field box next to it becomes a required field and the form will not submit until this text field is filled in. If the user selects one of the other radio button options then the text field is not compulsory. I am using a linked javascript validation file which checks that all fields on the form which I have stated as required - become required, but I am having problems getting this "Other" button and text field to work with it all and not have the submit continue without this text field being completed! any help would really be appreciated! Thanks in advance! Hi folks. Looking to see if anyone could tell me where I'm going wrong with this script... I'm trying to have a field automatically filled with the day of the week ("Monday", "Tuesday", "Wednesday" and so on), upon the user selecting a date from the datepicker jQuery. If this isn't clear, I'll clarify further down the page. Here is the script: Code: <script type="text/javascript">
jQuery(document).ready(function($){
$('input[name="item_meta[428]"]').change(function(){
var d = $('input[name="item_meta[428]"]').val();
var n = new Date(d).getDay();
if(n == 0)
val v = 'Sunday';
else if(n == 1)
val v = 'Monday';
else if(n == 2)
val v = 'Tuesday';
else if(n == 3)
val v = 'Wednesday';
else if(n == 4)
val v = 'Thursday';
else if(n == 5)
val v = 'Friday';
else if(n == 6)
val v = 'Saturday';
$('input[name="item_meta[429]"]').val(v).change();
});
});
</script>
I'm basically trying to say, if the user selected today (15/05/2012) in the field 428 it would fill the field 429 with "Tuesday". Again, if the user selected 18/05/2012 in the field 428 then it would automatically fill field 429 with "Friday". It's being done to work in conjunction with a wordpress plugin called Formidable Pro hence the item_meta[428] etc. Any assistance would be greatly appreciated. Sam. Hi all, Thanks for reading. I'm having an issue trying to accomplish the following - I have a text field (field1) already displayed on the HTML page. However, there's a link where you can add additional text fields to the page as well. When the link is clicked, the second text field is added successfully (field2), and when the link is clicked again, the third text field (field3) is added successfully. However, the third field does not add itself to the page, and the text for anything greater than a third field also isn't displayed after. This obviously means that my "fields" variable is not working right, so I'm wondering, would anyone be able to assist me to help me get that variable processing correctly? Code: <script language="javascript">
fields = 1;
function addMore() {
if (fields = 1) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field2' size='25' /> <span>Field 2.</span>";
fields = 2;
} else if (fields = 2) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field3' size='25' /> <span>Field 3.</span>";
fields = 3;
} else {
document.getElementById('addedMore').innerHTML = "Only 3 fields are allowed.";
document.form.add.disabled=true;
}
}
</script>
Here is the code in my HTML - Code: <input type="text" name="field1" size="25" /> <span>Field 1.</span> <div id="addedMore"></div> <p class="addMore"><form name="add"><a onclick="addMore()">Add another field.</a></form></p> Thank you very much. like for example i have text areas named upload1 and upload2 when I click or add input on upload1 a drop down list below upload2 will not change, but when I add input on upload2 the dropdown will select "parts" Hey all. I have a simple validation I need to do. I need to just make sure that a Checkbox is checked, and that a Text field has content. Sounds simple but I cannot find any thing that has a check and a text field. Here what I have. Can I modify this script to do this? A Checkbox MUST be checked and Text field MUST be filled out. This currently does the text field fine, but no Checkbox obviously. How can I add a checkbox validation to this? Thats it. Any help is appreciated. Code: <script type="text/javascript">
var textFields = ["digsig"];
function validateForm( )
{
var oops = ""; // must initialize this!
var form = document.sig;
for ( var t = 0; t < textFields.length; ++t )
{
var field = form[textFields[t]];
var value = field.value.replace(/^\s+/,"").replace(/\s+$/,""); // trim the input
if ( value.length < 1 )
{
oops += "You MUST enter your Digital Signature";
}
}
if ( oops != "" )
{
alert("ERROR:" + oops);
return false;
}
}
}
</script>
Why is it when I have multiple "list" values the function works fine but when there is only one "list" value it tells me to "Select a Record" even when it is selected. Code: <script>
function listValuesexcel(form)
{
var cbs = form["list[]"];
var vals = ""
for ( var c = 0; c < cbs.length; ++c )
{
var cb = cbs[c];
if ( cb.checked ) vals += "," + cb.value;
}
if (vals.substring(1) == "") {
alert('Please select a record!');
return false;
}
document.excelForm.excelForm.value = vals.substring(1)
document.excelForm.submit();
}
</script>
<ul>
<li><a onClick="listValuesexcel(theForm)" title="Excel Report" href="#" > Excel</a></li>
<BR>
<!-- END TABS -->
<form method="POST" action="index.php" name="theForm" >

Hello all. I need to use javascript to validate 6 text inputs to make sure data is entered and they are not empty. However, there is a checkbox above this and if the checkbox is checked I need these areas to NOT validate as they become optional at that point. Here is what I have: Code: function validateCheckbox() {
if(document.forms["form1"].sales.checked) {
if(document.forms["form1"].input1.value.length < 1) { // x
return false;
}
else {
return true;
}
}
}
The above is if the box is checked to validate the field. I want it to do the opposite. How would you do the above with the If statement referring if the check box is NOT checked? And how could I add more fields to check then just one? I am new to javascript so any help or guidance is appreciated. i need help with the following problem : I installed a new extension on my website , that allows a customer to select a delivery date, by displaying a table where he chooses a date. The script works perfectly but has 1 big downside . I can't make it a *required field . I am running a flower shop so delivery date is mandatory. anyways, i want to know if i can set it to mandatory modifying this code.. Code: <?php
class MagentoTeam_Ddc_Block_Form extends Mage_Checkout_Block_Onepage_Abstract{
protected $delivery_date;
protected $customer_comment;
public function getDeliveryDate(){
if(is_null($this->delivery_date)){
$this->delivery_date = $this->getCheckout()->getQuote()->getDeliveryDate();
}
return $this->delivery_date;
}
public function getCustomerComment(){
if(is_null($this->customer_comment)){
$this->customer_comment = $this->getCheckout()->getQuote()->getCustomerComment();
}
return $this->customer_comment;
}
public function getConfigData($node){
return Mage::getStoreConfig(sprintf('magentoteam_ddc/%s', $node));
}
public function getFirstDay(){
return intval(Mage::getStoreConfig('general/locale/firstday'));
}
}
thank you in advance! Hi Folks, I'm trying to figure out a script to transfer selected checkbox information to another page. I'm making a needs list for a non-profit group and the list is "huge" so I thought it would be nice to have something where the viewer could have a list of the items they checked to donate instead of printing out or transmitting the six pages for the entire list. I found a script in the archives from 10/2002 that "Adios" wrote in reply to an inquiry. It is real close to what I want but it involves transfering graphics instead of the text information from the checkbox. I've been working on it for several days but cannot get it to work. Here's Adios' script: <html> <head> <title>untitled</title> <script type="text/javascript" language="javascript"> var lefty = righty = null; function pop_twins() { lefty = open('lefty.htm','lefty','left=0,top=0,width='+screen.availWidth/2+',height='+screen.availHeight+',status=0'); righty = open('righty.htm','righty','left='+screen.availWidth/2+',top=0,width='+screen.availWidth/2+',height='+screen.availHeight+',status=0'); lefty.focus(); righty.focus(); } </script> </head> <body> <a href="javascript:void pop_twins()">pop 'em</a> </body> </html> [lefty.htm] <html> <head> <title>The Source</title> <base href="http://aabode.com/victoria/images/"> <script type="text/javascript" language="javascript"> var path = 'http://aabode.com/victoria/images/'; function addIMG() { var HTML = '', img, box_arr = document.addform.ImgAdd, which = 0; HTML += '<html><head><title>The Destination</title></head><body>'; HTML += '<h1>&#149; The Destination &#149;</h1>'; while (box = box_arr[which++]) if (box.checked) HTML += '<img vspace="5" border="1" src="' + path + box.value + '"><br>'; HTML += '</body></html>'; if (opener.righty) { opener.righty.document.write(HTML); opener.righty.document.close(); } } </script> </head> <body> <h1>&#149; The Source &#149;</h1> <form name="addform"> <input type="checkbox" name="ImgAdd" value="apple.jpg" onclick="addIMG()"> <img align="middle" vspace="5" border="1" src="apple.jpg"><br> <input type="checkbox" name="ImgAdd" value="strawberry.jpg" onclick="addIMG()"> <img align="middle" vspace="5" border="1" src="strawberry.jpg"><br> <input type="checkbox" name="ImgAdd" value="pumpkin.jpg" onclick="addIMG()"> <img align="middle" vspace="5" border="1" src="pumpkin.jpg"><br> <input type="checkbox" name="ImgAdd" value="lettuce.jpg" onclick="addIMG()"> <img align="middle" vspace="5" border="1" src="lettuce.jpg"><br> <input type="checkbox" name="ImgAdd" value="raspberries.jpg" onclick="addIMG()"> <img align="middle" vspace="5" border="1" src="raspberries.jpg"><br> <input type="checkbox" name="ImgAdd" value="tomatoes.jpg" onclick="addIMG()"> <img align="middle" vspace="5" border="1" src="tomatoes.jpg"> </form> </body> </html> [righty.htm] <html> <head> <title>The Destination</title> <body> <h1>&#149; The Destination &#149;</h1> </body> </html> I would like to also include a print function and submit. The print feature is not a big issue as the viewer can print from the browser but I thought it would make the transferred information page a bit more snazzy and they will have a record of thier selections. On the submit I don't have a URL setup yet but if you could put something like "URL HERE" in the script placement I can change it when they get up and going. Thanks in advance for your help, and thanks for taking the time to read all this. Hi, I'm new to JavaScript.

Hi, Is there anyone who could help me figure out how to Change a Hidden Fields Name based on selected option. The hidden fields name is sent off and I need to change the name depending on what option they select. For if they select MyList the hidden field name needs to be SelectLists[40] or if they select testlist the hidden field name needs to be SelectLists[41]. This is probably way, way off but I've done this and it doesn't work. Any help would be greatly appreciated, thanks. <script language="JavaScript"> function changelist() { //here we assign the value of the hidden input to x x=eval(document.getElementByName("SelectLists[40]"); if(document.getElementById("SelectLists[40]").selected=true x=SelectLists[40] else(document.getElementById("SelectLists[41]").selected=true x=SelectLists[41] else(document.getElementById("SelectLists[42]").selected=true x=SelectLists[42] //now we assign the new value to the input document.getElementById("theHiddenInput").name=x; //and now we test alert(document.getElementById("theHiddenInput").name) } </script> <input type="hidden" id="theHiddenInput" name="SelectLists[40]" value="Yes"> <select class="inpBox" style="width: 287px" name='mailinglist' id="lists" onchange="changelist()"> <option value="SelectLists[40]" name="SelectLists[40]" id="SelectLists[40]">MyList</option> <option value="SelectLists[41]" name="SelectLists[41]" id="SelectLists[41]">testlist</option> <option value="SelectLists[42]" name="SelectLists[42]" id="SelectLists[42]">testlist2</option> I've inherited this piece and now I'm suppose to add to it. Its basic function currently is when the "Other" option is selected, a hidden text field shows. Now, I need to add when "Athletics" is selected, another hidden select group will show. I've set up the new Select group already, but not sure how to incorporate it into the already existing script. I've been researching for two days, and hopefully this form will be helpful. Code: <select id="Program" name="Program" size="1" onchange="
$other = document.getElementById('other_program').style;
$invoice = document.getElementById('invoice');
if (selectedIndex==6) {
$other.visibility='visible';
if ($invoice.value == 'General Fund') $invoice.value='';
} else {
$other.visibility='hidden';
if (selectedIndex==1) {
$invoice.value='Renegade Fund';
} else {
$invoice.value='Please Specify';
}
}
">
<option selected="selected" value="Not Selected"> - - Select One - - </option>
<option value="Athletics">Athletics</option>
<option value="Drum Line">Drum Line</option>
<option value="Renegade Fund">Renegade Fund</option>

Hi, i have a page with lots of checkboxes and hidden fields. When i tick a checkbox i want it to give the hidden filed a value. But give it no value if it is not ticked. For every checkbox i have a hidden field is with it. Both the checkbox and the hidden field send information. I have used some js scripts but they don't seem to work with more than one checkbox. Please can you help. Example: <input type="checkbox" name="box1" id="box1" value="4th July 2009,"> <input type="hidden" name="price1" id="price1" value="0"> So when box1 is ticked it then gives price1 a value. But if not ticked then the value remains at 0. I want it to give a value of 699. There will be about 100 checkboxes and hidden fields on the page. Also onclick behaviours do not work because it may still send the information if the checkbox is not checked. So for the next checkbox and hidden field i use box2 and price2. Thanks for your help. Hello. I have a textarea where user can select a text then copy to clipboard (using EditArea script for highlighting) I need append additional information to the selected text so it won't be visible in the textarea, but only appear after copied to clipboard. For example: Code: text line one text line two text line three user selected word "two", hit CTRL+C to copy into clipboard (or used browser's context menu), but in clipboard it should be saved as: "selected word 'two'" What would be the approach? Thank you. I've not really an idea how to do this. I know how to do it in PHP, but I need it dynamic <input type="checkbox" name="facebook" value="1" /> if($_POST['facebook'] == 1) echo "<input type='text' name='facebook_url' />"; Could someone tell me how I should do this. Thanks. I have a text field, call it income, that when the input is > 0 I need to dynamically show the next text box, and if it is blank hide the next text box. I would like to use onBlur but can't seem to get it to work. Can I do this? Help I am finishing up my Form page, and totally forgot to have a numeric only field.
