JavaScript - Add Form Field Value To Url??

Hi!

I use the :: Form field Progress Bar from DynamicDrive:
Form field Progress Bar

Now I trided to change the text when the textarea is full "Limit:100%" to "Your max. characters is reached"

I trided it but with no luck.
This is the main code..
Code:

<script type="text/JavaScript">

function textCounter1(field,counter,maxlimit,linecounter) {
	// text width//
	var fieldWidth = 137;
	var charcnt = field.value.length;        

	// trim the extra text
	if (charcnt > maxlimit) { 
		field.value = field.value.substring(0, maxlimit);
	}

	else { 
	// progress bar percentage
	var percentage = parseInt(100 - (( maxlimit - charcnt) * 100)/maxlimit) ;
	document.getElementById(counter).style.width =  parseInt((fieldWidth*percentage)/100)+"px";
	document.getElementById(counter).innerHTML="Limiet: "+percentage+"%"
	// color correction on style from CCFFF -> CC0000
	setcolor(document.getElementById(counter),percentage,"background-color");
	}
}

function setcolor(obj,percentage,prop){
	obj.style[prop] = "rgb(80%,"+(100-percentage)+"%,"+(100-percentage)+"%)";
}

</script>

This is the place where the text is set.
Code:

 ((fieldWidth*percentage)/100)+"px";
	document.getElementById(counter).innerHTML="Limiet: "+percentage+"%"

Help would be highly appreciated !

Is there a way to give an input or textarea field the focus and set the focus to begin right at the end of the current text in the field?

I need to learn how to clear form fields when a user clicks on them.

Here is the site in question:

http://www.yourvancouvermortgagebroker.ca/apply

They used to work, but then I changed the field value and now it doesn't work on some of the fields (whichever ones I changed).

Here is a link to the .js file:

Hello,

I have several event handlers on my page; one of them doesn't work. I'll post them all here, indicating how they are executed:

#1: Works
[CODE]<script type="text/javascript">
function combName() {
var fname = document.forms[0].fname.value;
var lname = document.forms[0].lname.value;
document.forms[0].name.value = fname + " " + lname;
}
</script>[CODE]
NOTE: The "lname" field uses "onKeyUp" to make the script run. A hidden field named "name" is populated with the concatenation.

#2: Works
(this script is too long to post; it is a validation script and runs via the "onSubmit" in the form tag.)

#3: Doesn't Work
[CODE]<script type="text/javascript">
function combPrograms()
{
document.forms[0].00N70000002WNax.value = "1st Choice: " + document.forms[0].sf1.value + document.forms[0].alameda1.value + document.forms[0].sanmateo1.value + document.forms[0].marin.value + document.forms[0].cc1.value + "2nd Choice: " + document.forms[0].sf2.value + document.forms[0].alameda2.value + document.forms[0].sanmateo2.value + document.forms[0].marin2.value +
document.forms[0].cc2.value;
}
</script>[CODE]
Note:
1. Not all of the values for Choice 1 and Choice 2 are populated.
2. For that reason, one of the later, unrelated text fields in the form has "onKeyUp="combPrograms()" to run the event.
3. A hidden field named 00N70000002WNax is populated with the concatenation.

Any help is much appreciated!

Hi. I have a form and if a field is blank a message pops up. This doesnt stop my php from running though and takes the user to another page.

Is there a line to keep them on that page untill all fields are filled out?

code so far is simple.

<script type="text/javascript" language="JavaScript">
function nameempty()
{
if ( document.form.subject1.value == '' )
{
alert('No name was entered!')
return false;
}
}
</script>


//then down the bottom I have a small bit that implements that code

I have some code that uses a form, and will check it and show an image.

If you have/know a script that is simple, let me know!

Otherwise, I'm wondering if someone who is proficient in JS/HTML could help me with this task. It's all coded, I just need some help with an error I am getting.

Thanks,
Blockis

Though I know nothing about Javascript, that didn't stop them from assigning me the task of mothballing our Excel spreadsheets and going to fillable .PDF forms. Here's my first of many questions:

In one of my fillable PDF forms, I take the numbers (entered by the user) from two or three fields and calculate those placing the answer in a seperate field. Since we work with very large, and very small numbers, I want the number in the answer field to be displayed in scientific notation. Adobe Acrobat is not very flexible when it comes to selecting a number format, so a script is obviously needed to do the conversion.

I've also noticed that Adobe doesn't like the user entering a number in a field in scientific notation. My number calculates out correctly if you enter .000000274 in the field, but does nothing if you enter 2.74E-7. Help with that would also be greatly appreciated.

I have been staring at this code for too long and need some help. I want to pass a value received through the Url to another screen with new data by a form using the method="get". I have tried several different ways, my latest attempt was to use a hidden field hoping that would add to the url string but it isn't working.

Thank you in advance

Here is my code, its not pretty

I have modified a free JS function from he
http://www.tangorangers.com/examples...post/index.php

To dynamically add text fields to the form. My work-in-progress version is he
http://jimpix.co.uk/junk/test/6.html

On the form, I have a hidden text field:

Code:

<input type="hidden" name="hiddenCount" value="" />

What I'd like to do is to increment the hiddenCount each time the "Add" fields button is clicked.

This is the button:

<input id="add_contact()" onclick="add_contact()" value="Add" type="button">

And this is the JS function:

Code:

var contact_counter = 0;
function add_contact()
{
	if (contact_counter < 9)
	{
	contact_counter++;
	var newFields = document.getElementById('add_contact').cloneNode(true);
	newFields.id = 'contact';
	newFields.style.display = 'block';
	var newField = newFields.childNodes;
	for (var i=0;i<newField.length;i++) {
		var theName = newField[i].name
		if (theName)
			newField[i].name = theName + contact_counter;
	}
	var insertHere = document.getElementById('add_contact');
	insertHere.parentNode.insertBefore(newFields,insertHere);
	}
}

I'm new to JS. I could just about edit the JS function to slightly modify it from the tangorangers version (I only changed it v. slightly).

To somehow increment the value in the hidden field each time the button is pressed is beyond me though!

Any advice much appreciated.

Thanks

Using the url test.html?a=john&b=doe

I am using the following code:

<script type="text/javascript" language="javascript">
function getUrlVars() {
var map = {};
var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi;
function(m,key,value) { map[key] = value; }); return map;
}
var john=getUrlVars(map[a]);
alert (getUrlVars(map[a]))
alert (john)
</script>

I can't seem to get an alert to show me anything. The eventual result is not an alert, but a document.write to post the url contents to various form fields for firstname= and lastname= etc.

I am really having a hard time using the document.write function, and am not sure how to employ it, whether in the same script statement or in a separate script in the body.

Greetings,

I'm working on a php/mysql app that has multiple tabs with multiple form fields. I am trying to incorporate a javascript form field detection function that alerts the user that they have not submitted their changes if they try to navigate away. The detection works as designed, but the problem I am having is when the form is submitted, the script senses an unload and still fires the alert. The form submits to itself and updates the database and then reloads the page with the new values. Is there a way to have the script ignore the forms submit url and skip the form check?

Here is the code ( NOT mine, found it somewhere else.)

Code:

<script language="javascript">
  var ids = new Array('description');
  var values = new Array('<?php echo $detail['description']; ?>');
  
  function populateArrays() {
    // assign the default values to the items in the values array
    for (var i = 0; i < ids.length; i++) {
      var elem = document.getElementById(ids[i]);
      if (elem)
        if (elem.type == 'checkbox' || elem.type == 'radio')
          values[i] = elem.checked;
        else
          values[i] = elem.value;
    }      
  }
  var needToConfirm = true;
  
  window.onbeforeunload = confirmExit;
  function confirmExit() {
    if (needToConfirm) {
      // check to see if any changes to the data entry fields have been made
      for (var i = 0; i < values.length; i++) {
        var elem = document.getElementById(ids[i]);
        if (elem)
          if ((elem.type == 'checkbox' || elem.type == 'radio') && values[i] != elem.checked)
            return "Your changes have not been saved. Are you sure you want to leave?";
          else if (!(elem.type == 'checkbox' || elem.type == 'radio') && elem.value != values[i])
            return "Your changes have not been saved. Are you sure you want to leave?";
      }
      // no changes - return nothing      
    }
  }
</script>

The url of the page is "edit.php?&mode=edit&t=2&id=284&cn=2009-002"
The only detectable change to the query string would be the 't' variable.

Basically what I want to do is have the script look for a change in the 't' variable and if detected, check the form values for changes. If 't' doesn't change, skip the script completely.


Thanks..

I need help troubleshooting javascript I am using to concatenate two fields in a form and populating a hidden field with them.

Here's the javascript:
<script type="text/javascript">
function combName() {
var fname = document.forms[0].fname.value;
var lname = document.forms[0].lname.value;
document.forms[0].name.value = fname + " " lname;
}
</script>

Here are the form fields:
<input id="fname" name="fname" type="text">
<input id="lname" name="lname" type="text" onKeyUp="combName()">
<input name="name" type="hidden" id="name" size="20" maxlength="80">
<input name="Submit" type="submit" id="OnSubmit" value="OnSubmit">

What am I doing wrong? Thanks.

Hello,

First off thank you for looking at my post. Please forgive me if I do something incorrectly here. I have never posted in a forum before.
You are very kind to assist me in this problem.

I wish to send the javascript calculated value in a form from one page to another page form. I just need the one value sent. The value is "answer: in the code below. I would like to send it to a form page called "answer.html"

I am not a computer person, and I am doing this in frontpage. I do not know how to write java or anything, I just copied this from a free script site and am trying to use it.

Thank you once again for your kindness and patience with me. Thanks to all you experts!

Michael

here is the code I have.

Thank you again for helping me in plain language because I do not have the skills that all of you do.

Hi guys,

This has been asked before, and i've seen many of the previous posts. And tried for hours. But finally i've broken and have to ask for help.

What am I doing wrong here? Can someone please explain?

Code:

var u=document.forms["lead"]["name"].value;
var v=document.forms["lead"]["city"].value;
var x=document.forms["lead"]["country"].value;
var y=document.forms["lead"]["mobile"].value;
var z=document.forms["lead"]["email"].value;

if (u==null || u=="")
  {
  alert("Please enter your first name.");
  return false;
  }
  
  if (v==null || v=="")
  {
  alert("Please enter your city.");
  return false;
  }
  
  if (isNaN(lead.y.value))
  { 
  alert("bloody work!");
  return false;
  }
  
  if (x=="Argentina" && y.length < 11)
  {
  alert("Please enter a valid Argentinian phone number.");
  return false;
  }

Thanks in advance.

I need when I click to type into a form field, I need an onclick event to show another form field. I would assume this would be a hiddin div or an on click event to post another form field.

So in theory just because I actually clicked into one form field...another form field shows up underneath it...can anyone help...
