I am converting a calculator type page into javascript. In this particular calc., there are some text input fields and a couple of drop-down selects. One set of selects has 2 functions so that when it is changed, it changes the other select menu's value (and vice-versa). This works as expected. Code:
View 5 RepliesI'm trying to get an upload popup working with the jQuery form plugin[URL].. When I click a link I load a form html from the server and add it to a container div by setting the div's html attribute.

I am trying to create a form that writes text to an HTML canvas when submitted. Eventually, the function that writes the text will be more complex. The problem is the text only appears briefly, because the function is only called once when the form is submitted. I want the function to be called continuously after the form is submitted.How do I do this? I have had very little experience with JS.A lame (failed) attempt...

Is there a way to access a forms details by sending its parameters to a
function. For example, I have a form named "myForm" populated by a drop down box, so that <select name="mySel">
I am trying to send the form and drop down box name to a javascript
function, eg onChange="update( "myForm", "mySel") so that, within the Javascript update(formName, selName) function I can access the forms doing something like this:
update(formName, selName)
{
selected_index = document.forms.formName.selectedIndex;
selected_value = document.forms.formName.selName[selectedIndex];
}
so that I can access the specified value using the input arguments to
the function, rather than doing
selected_index = document.forms.myForm.selectedIndex;
selected_value = document.forms.myFormn.mySel[selectedIndex];
The reason for this is because I have a lot of drop box boxes that are
changed by the user.
The below script keeps a running total dollar tab. It uses the "name" of the elements but I would like it to use the "ID" instead. How to adjust the function to look at the id. I've changed the first 2 form elements to id.

<!-- function CalculateTotal(frm) {
var order_total = 0
// Run through all the form fields
for (var i=0; i < frm.elements.length; ++i) {
// Get the current field

// Get the field's name
form_name = form_field.name
// Is it a "product" field? .....
I have a form that submits a POST request when data is submitted. A Servlet then processes this POST request and a JavaBean is used to make some calculations. The HTML response is not generated within the Servlet but instead I forward the request to a JSP to generate the response. - This all works fine.
However, I am suck trying to validate the form on the client side with a JavaScript function before the form is submitted.
Here is my index.jps:
Regardless of whether incorrect input is given, the data is still POSTed to the server and calculated on or a Server Side error is given.
Am I correct in calling the function onClick?
The validation essentially needs to be so that:
- Student field contains a string
- Score1, Score2, Score3 and Score 4 contain a number between 0 and 100
Is there any way to submit a form with a function?
View 1 Replies View RelatedI am submitting a form using an image as the link to a js file. The image calls a js function which checks fields- issuing alerts for errors - if no errors it then submits the form.
I would like to have a final confirm box run from the function before the form is submitted. I guess I would have to use the return statement somehow but I can't see quite how.
I'm doing a form, 300 questions, I already done the blank validator function, but i'm quite struck for this correction function, usually for 10 question i do some "if" "elseif" but for 300 question it's not possible xD.
I have a classic form with true or false radio buttons i want to be able to show the question and the answers made and to count the number of "true" returned.
I want to have a button in a form that only calls a Javascript function, but not refresh the page, how do I do this?

I have a vague idea of what might be going wrong but I have no idea what I should be doing instead. Here is what I'm trying to do: User inputs X and Y coordinates into form validate that they are numbers do a little bit of maths redirect to a php script with a single variable tacked onto the end of the url Here is the form code:
//part of a larger php script to make the form
echo "<form name='gotoForm' onsubmit='return coordCalc()'>

<legend>Go to Square</legend>
X <input type='text' id='X' size='1' maxlength='3'/>

I'm not aware of JS-Scripting, so I used phpform.org to create a contact form for my website. Now they give me the download link, but without the opportunity to send the data put in via mail (senseless demo-stuff). Now I count on you to find the area where to add the code for sending (all) the data to an emailadress. Here is the whole form in a zip file: [URL]

function pickitem(id,type){
opener.document.getElementById("form").type.value = id;

so i'm passing in an id and a formfield e.g. txtName The problem is with the type.value - i haven't touched javascript for ages so i'm really rusty!!
My strength is not java script and with the complex issues of dealing with the Vbulletin interface and then the java script which i do not really understand yet fully I hopeing some good soul will come to my add fast and get me through this.I do not expect that I will find someone that has the knowelage of vbulletin but I need to be correct java script first but if someone knows Vbulletin i modifyed the calendar_jump which is calendarjump in the templete system.
Here goes the problem is my form is not calling up my java script - even allought the java is not doing anything right now I have dump some idea of what i want to do inside it for clearlty to my idea what i am trying to do!The point is I need my java script function "process_selected(this.form)" to be called before the submitting of the form in the form of a $_GET to the server.
<script type="text/javascript"> function process_selected(this.form) {
on.form.submit();

I am looking to recreate a form function like this website: [URL] What happens when you click the answer to the question the form scrolls to the next function. I would love to know how this is done. I am not a javascript developer but having looked into this the form uses scriptaculous.js and prototype.js. Is there an online form builder or a program out there that can re-create this or is it just a simple bit of javascript added onto a form?

I am trying to combine a php form submission with a javascript function.Basically my form includes an address and UK postcide and I need to get the longitude and latitude of this address using the google map api. I have a javascript function that performs this geocoding.My problem is that I need the following sequence of events to occur.
1. User completes form including mandatory address and postcode
2. User clicks on the "Submit" button
3. Javascript function is called to retrieve the longitude and latitude
4. If successfully retrieved the longitude and latitude, submit the form data including the retrieved longitude and latitude.
Here is my javascript geocode function
Code:
function geoCode(location) {
if (location != '') {
localSearch.setSearchCompleteCallback(null,[code]...
Code:
<form name="myform" method="post" action="" onsubmit="return geoCode(document.getElementById('postcode').value);">
This is not working and it appears to just immediately submit the form without going into the following bit of the javascript function
if (localSearch.results[0]) {
In the DOM Scripting book by Jeremy Keith, he provides this function:
Code:
function styleElementSiblings(tag,theclass) {
if (!document.getElementsByTagName) return false;
var elems = document.getElementsByTagName(tag);
for (var i=0; i<elems.length; i++) {
var elem = getNextElement(elems[i].nextSibling);
addClass(elem,theclass);
} }
And then says to pass the values "h1" and "intro" to this function in this form:
styleElementSiblings("h1","intro");
I'm just a little stuck on how to "pass the values". Presumably I've missed something simple. I've tried just pasting that line before the function, but no luck. He also provides a function that allows multiple functions to load at once, called addLoadEvent, so I tried this, also with no luck:
addLoadEvent(styleElementSiblings("h1","intro"));
I have been asked to make some changes to a form that uses Javascript for the form validation. There is a 'function' that contains the variables of the various form fields and then further code to raise 'alerts' if one of the fields on the form hasn't been filled in. My problem is that for some reason I am unable to add an extra variable to this code after the field of 'County' (this will hopefully make sense when you see the code / link...) and I am stumped as to why. I am able to add variables for all of the other required fields except for 'Postcode' after 'County'. This is the case for both forms. The link is here: [URL] and the code I am trying edit is below. The issues seems to be when I add && isPostcode() to this chunk of code:-
Code JavaScript:
function checkAvailibility()
{
// re-calculate...
calculate ();

I have been using this simple js function to validate a field in a form is filled in.

Now I have a page with multiple forms and I would like to use the same script to validate depending on which form is submitted. I thought I should be able to do something like this.... but know very little javascript...any suggestions? Code:
I want to have two options on a form, one to refresh the form, and another to submit the form.
the way i have it set up now is through a regular html form with asp doing the calculations needed in it. if i change the value in a textbox, i want to be able to press refresh and have asp recalculate it. i'm able to do that, but now i don't have a way to actually submit the form because i already have a form method that sends it back to asp for recalculation.
can you think of a way to submit a form to two different locations based on two different buttons?
