JavaScript - Javascript - Inserting Commas Dynamically.

I currently have a page which, when the user clicks a button creates a new row displaying a form. I also have other forms on this page however so I was wondering if anyone knew how to close a form using javascript? Thanks for any help. My code to create the table row and form are below...

Code:

myform = document.createElement("form");
	myform.method = "post";
	myform.action = "editdetails.php";
	myform.id = "editemail";
	myform.name = "editemail";
	
	var a=document.getElementById('editdetailstable').insertRow(2);
	var b=document.getElementById('editdetailstable').insertRow(3);
	
	var x=a.insertCell(0);
        x.innerHTML="New Email:  ";
	x.align = "right";

	var y=a.insertCell(1);
        y.innerHTML="<input type='text' name='email' id='email' />";
	
        var z=b.insertCell(0);
	z.innerHTML="<input type='button' value='Change' />"
	z.colSpan = "2";
	z.align = "center";

Hi everyone,

I am pretty new to JS and I am looking for help writing a function that will dynamically calculate filed values.

I have a PHP-generated form which may have a varying number of fields. I need to:
1. calculate the line total for each row -- unitprice * units = linetotal
2. calculate total of all linetotals.

I have named my fields as follows:

unitprice[1], unitprice[2]... , units[1], units[2], ...

I have the following calculate function:

Code:

function calculateOld() {
	// get both values
	unitprice = document.forms["invoice"].unitprice.value;
	units = document.forms["invoice"].units.value;
	// do some calculation
	lineTotal = formatNumber((unitprice * units), 2);
	// set the value in the right field
	document.forms["invoice"].linetotal.value = lineTotal;
	
	unitprice2 = document.forms["invoice"].unitprice2.value;
	units2 = document.forms["invoice"].units2.value;

	if(unitprice2 != '') {
		// do some calculation
		lineTotal2 = formatNumber((unitprice2 * units2), 2);
		// set the value in the right field
		document.forms["invoice"].linetotal2.value = lineTotal2;
		document.forms["invoice"].totalprice.value = formatNumber((parseFloat(lineTotal) + parseFloat(lineTotal2)),2);
	}
	else {
		document.forms["invoice"].linetotal2.value = '';
		document.forms["invoice"].totalprice.value = formatNumber(lineTotal,2);
	}
}

This does calculate what I need but only if I have up to two rows. I need to make the function dynamically count how many rows there are, and calculate the linetotal for each row. And here's where my limited JS knowledge brings me to a halt.

I have been thinking about what this new and dynamic function should look like, but that's the best I could produce...

Code:

function calculate() {
	
	var unitprice[i]	= document.forms["invoice"].unitprice[i].value;
	var units[i]		= document.forms["invoice"].units[i].value;
	var linetotal[i]	= formatNumber((unitprice[i] * units[i]), 2);
	
	return linetotal;
}

Your help will be appreciated. Please explain how things are done, don't just give me the code. Thanks in advance!

I'm attempting to run a small piece of code that will execute one of two source js files on my server. I have no problem creating the proper DOM script object with the proper type and conditional src value. However, when i add it to the document it does not seem to execute. I've tried adding it in two places, both using .appendChild();

myLocation.parentNode.appendChild(newScript);

and

document.getElementsByTagName("head")[0].appendChild(newScript);

(myLocation is a calculated element representing the current script tag)
In both these cases, the script tag is added to the document where I intended, but it does not appear to execute. The src has some doc writes in it and the tags the new script should generate right after itself are not there, as they are when I hard code the new sourced script tag into the document.

All in all, my confusion comes from the fact that when I write a <script ... src="mysrc.js"></script> into my document, it behaves differently than when I have a script write an identical tag into the document in the same location.

Also, fyi, I'm currently using Chrome (though I will require a multi-platform solution). Thanks for your time.

I'm new here and this is my first post, I hope I can find help here.

How can i dynamically generate this type of form element in javascript, including the table rows and columns enclosing the form elements and whenever that 'Add More' button is clicked, a new instant of the same form will generated and select drop down list populated.

I have try to google for solution, but without success.

I code in PHP, but i need it to integrate in my code.


Thanks for your help.

The below code is not inserting the smile into the textbox.
In IE8 I get an error around
Code:

if((sel.type == "Text" || sel.type == "None") && rng != null)

In Firefox 3.5 I get an error around:
Code:

if (es <= 2)

Each textarea has: id and name
Code:

<textarea class="textinput" id="about_me" name="about_me" cols="45" rows="6">

Hi Everyone

I'll explain the situation first:

I need to build a website that allows students to select from a drop down list and then hit an 'Add button'. From there, that value will go to another part of the screen and display as bullets. Once that list is built, they can hit a final submit button that sends an email to someone with everything they selected.

More Detail:

LEFT SIDE OF SCREEN:

[DROP DOWN LIST] <- this will have all the courses listed that we offer. Once once is selected.

[ADD] <- add button that puts the values from the dropdown list to an array.

RIGHT SIDE OF SCREEN:

My Courses:
* TEST1001
* TEST1002

This is being updated dynamically so that whenever the add button is hit, this lists grows.

[SEND] <- Send button

Thank you,

Hi,
I am using a javascript datepicker which works fine with simple textboxes:
For example:
I have a textBox startDate1 in the table below:
<form method="post" name="upload" action="">
<table id="tableId">
<tr>
<td>
<input type="text" name="startDate1" value="" readonly="true" size="10"/>
<script language="JavaScript">
new tcal ({'formname': 'upload','controlname': 'startDate1'});
</script>
<td>
</tr>
<table>
</form>

--Now I want to add rows dynamically to this table for which I have
<a href="javascript:addRowToTable();" >Add Row</a>

and the corresponding javascript function:
<script type = "text/javascript">
function addRowToTable()
{
var tbl = document.getElementById('tableId');
var lastRow = tbl.rows.length;
var iteration = lastRow;
var row = tbl.insertRow(lastRow);

var box = row.insertCell(0);
var element = document.createElement('input');
element.setAttribute('type', 'text');
element.setAttribute('name', 'startDate' + iteration);
box.appendChild(element);
}
</script>
--This code creates the text boxes properly, but I am not being able to add the datepicker to it.
Please suggest me a way to add the datepicker to the textboxes in the dynamically generated rows.

Thank You
Regards
Rusho Shaw

Anyone have a decent way of adding a fade affect to this script?

Below is the code.

My function:
Code:

function swap_content(id1,id2)
{
var tmp = document.getElementById(id1).name;
var theval = document.getElementsByName('primary_propertyp_id')[0].value;
document.getElementById(id1).name = document.getElementsByName('primary_propertyp_id')[0].name;
document.getElementsByName('primary_propertyp_id')[0].name = tmp;
document.getElementById(id2).id = document.getElementById('primary').id;
document.getElementById('primary').id = 'addressid_'+theval+'_div';
}

Applicable Code for primary info:
Code:

<div id="primary">
<label>primary to secondary:</label><input name="primary_propertyp_id" type="text" id="addressid_<? echo $row['primary_property_id']; ?>" value="<? echo $row['primary_property_id']; ?>"/>
</div>

Applicable Code for secondary info/link to change:
Code:

echo "<div id=\"addressid_" . $properties_row['id'] . "_div\">";
echo "<a href=\"#\" onclick=\"swap_content(&apos;addressid_" . $properties_row['id'] . "&apos;,&apos;addressid_" . $properties_row['id'] . "_div&apos;); return false\">Make Primary</a>";
echo "<input id=\"addressid_" . $properties_row['id'] . "\" name=\"addressids[]\" value=\"" . $properties_row['id'] . "\" type=\"text\">";
echo "</div>";

This is running through a PHP loop so it's making multiple divs and links for the secondaries. I am wanting to be able to swap out any of them to make them 'primary'....this works for the first click, but after the first click it makes every div id and input name the same as the first that was clicked.

It's also not working AT all if i click on the bottom link first, then a link above it. Top-down works, bottom-up doesn't...Please help

Thanks in advance,
Jeremy

I have search for about a week and still no luck.
I need to dynamically display mutliple images using javascript, no hardcoding. The images have different categories. For ex. bellTower01.jpg, bellTower02.jpg...and fountain01.jpg, fountain02.jpg....

-Use JavaScript to display several images and scroll through them
To display multiple thumbnails, arrange them into a small quantity (no more than 8 per page)
Provide pagination

I really really really need help. I have never done javascript before, so I'm still learning. I seriously checked out many threads and links but nothing works or is what I want. I hope someone can help me out and hopefully also allow me to become better at coding this kind of stuff.

I am not allowed to code in php for this project. I can only use javascript to display the images. Also, I don't really need anything fancy, like slideshows or rotations, I just the image to appear when I select that specific category. I want to get the images from my folder/directory.

Right now, I have it working as it just being hardcoded.
Below is my code for my galleries page:

//creates a session..initializes session data
session_start ();

Is there a built in function to format a number to 2 decimal places and to add commas like below.

2,222.33
30,033.98
1,222,345,99

Does anyone know of a good library/function that will add the commas to a number automatically as the number is entered into a field?

Hello all I am new here but this place looked great and like one of the only places where I could find the answer to my question.

I have created a page which pulls search results from various sites using PHP. It displays each result in a row in a table upon running.

I wanted to add a button saying "More information" at which point, a div would appear and load the associated link for that search result within an iframe within the newly appeared div. I've been able to get a div appear and disappear on button click but, I couldn't get it to dynamically load an iframe on click with the associated search results link.

Any suggestions are greatly appreciated. Also let me know if you need more information before assisting. Thanks!
