II'm running Joomla 1.5.23 and I've been trying to get validation on a component's form fields. In the header section, I'm properly loading the validator.js file, which contains the following:
//function to check empty fields
function isEmpty(strfield1, strfield2) {
strfield1 = document.forms[0].firstname.value
strfield2 = document.forms[0].lastname.value[code]....
My problem is that even if all fields are empty it will go to the next step.
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...
I have two frames. Frame "search" contains a search form specifying an onsubmit action like so:
<form ... ... </form>
The other frame contains a <img ... where the perform_search function is defined as follows:
<script language="JavaScript"> function perform_search() { var frame = parent.frames.search; var form = frame.document.forms.mainForm; form.submit(); } </script>
Now, when hitting Return in the search form, then foo() is called fine. But when clicking on the <img ... in the other frame, foo() is NOT called.
Is expclicitly calling foo() from perform_search() the only way to do it, or is there a magic incantation that might do what I want?
I have been searching high and low and I can't seem to find an answer. I am new at JS and I have created an form and when I click the on submit button it resets all the fields. The fields are always blank after I click reset. I have been working on this for 6 hours.
It just keeps resetting when I click Submit. I see for a millisecond that the total appears but then disappears along with the amount I put in the input text box.
I have created a simple form for uploading text files.You can see two versions of this it at: http:[url]....The form created with static HTML, works fine in current versions of the major browsers.However the dynamic form, fails (only) in IE.It fails because IE does not send the file at all when the form is submitted.
1.The user presses 'Submit Answers' button,which ends the exam and his result is displayed.This one is working fine.
2.The other is the timer expires.the exam finishes and the user's result should be displayed.This one is giving me a problem.
When the timer expires I want to run the onsubmit() function to assign values to hidden form inputs ,but I am unable to do so.How do I do this.Everything else with the timer function is working fine. Only a snippet of the actual code is given here,because the rest of it is ,I believe,irrelevant to the discussion.
I just noticed that if I use a "submit" button the "onSubmit" function call will be invoked. But if I use a button to call some other javascript and at the end of that javascrip I do something like "form.submit()" the "onSubmit" function call will NOT be invoked. I thought that was wierd. Can anyone shed some light? Here's a small example:
<script type="text/javascript"> function subform() { document.frm1.submit(); } function checkform() { alert('checking form'); return true; } </script> </head>
BUT $script_start_time must be populated at the exact moment the submit button is pressed, and not when the page where the form is first visited. Which is why I need a client side solution.
I am using Form in a PHP Code - which post the results to another external - application, and i would like to save some recordes in DB (when someone use the submit button) before moving on to the external-app. how could i do this in a javascript or is it possible?
I am in a JavaScript college class and right now we are learning about form validation, well before server side validation, and I am having an issue with validating the field if the user updates it and hits submit again. The red .setAttribute function is not removed. My code is below, please excuse the noobness I am displaying here.
I have created web pages that do client-side form validation using the onclick directive. E.g.,
<form action=other_page.cgi method=post> Enter your age: <input name=age> <input type="submit" value="" validate_form()"> </form>
where validate_form() returns true or false depending on whether the user entered a valid age.
This does what I want almost everywhere (e.g., Firefox on FreeBSD, Safari on Mac, IE on Win2000) but recently I have become aware of an exception: IE on WinXP.
On WinXP's IE, validate_form() is called (and will display an alert box if that's that's what I coded), but whether it returns true or false, the form is submitted. (Then we do the server-side validation and throw up an error page, but I'd rather catch this client-side.)
So the question I have is: why is WinXP so weird about this? Previous versions of IE didn't do this.
While looking into this, I've discovered I can also do an onsubmit check in the form tag, e.g.,
Is onsubmit new or has it been around for a while? Can I trust old Mozillas on Linux to do the right thing with it? Windows is actually a small portion of the target audience, but I like to make things work for everyone.
Does it make a difference if the form is submitted to the same page or a different page? I don't have ready access to Windows XP to test this out.
I'm trying to create a form whose onsubmit returns false if the form should not be submitted. Normally this type of thing works great for me:
<form onsubmit="return somefunction()">
where somefunction returns false. But I'm trying to do some thing where in some script block, the function gets added:
form.attachEvent("onsubmit", function () { return somefunction() });
(not worrying about crossplatformosity, sorry). But that doesn't work, the form is always submitted. Is there something else I need to be doing to make this happen?
I have the following form working with on onsumbit function, but I would like to change it so that instead of having to click the purchase button to see total price, you only have to change the quantity text box input. I just can not seem to get it to work.
<script language="javascript" type="text/javascript"> function checkQuantity(frm) { var succesful = false; var numQuantity; numQuantity = parseInt(frm.Quantity.value); var numTotalPrice;
if (numQuantity != 0) { numTotalPrice = numQuantity * 4; frm.TotalPrice.value = numTotalPrice; //new String(numTotalPrice); successful = true; } else { alert("Sorry must order more than 0"); successful = false; } return succesful; } </script>
I am wondering if it is possible for me to replace my form submit button with an animated gif (fake progress bar), after the button has been pressed.Having so far disabled the button onclick, I would instead be happy if I could simply change the button text from 'Click here to submit' to 'Processing...'I have done some searches here but I'm finding references to innerHTML, etc., and I'm getting lost now.
I want to load an image with JS within the form event "onsubmit" without stipping the submit action of the form.
What I do is the following:
var img = new Image(); img.onload = function(){ myfunction(); };
[Code]....
This logic is a MUST for me, I mean I don't want to use settimeout to postpone the form submit, and I have to call the URL_FOR_PHP_SCRIPT_TO_DO_SOME_LOGIC this way since this code is on a JS file from different domain. This logic works fine on all browsers, and the request to call the image is sent -which is what exactly I need-, however on safari it doesn't call the image request, and start posting the form directly. I tried to add an "onunload" event on the page containing the form when the browsers is safari, but this didn't help too, and the form still submitting data directly without starting sending the request to load the image.
I'm developing am income tax calculator, and everything is going swell. Currently the user can type in their adjusted gross income (AGI), hit submit, and learn the amount of income tax they would pay, their tax rate, and their income after tax.
I've played around with the events to get the submit button to work in FF, IE, Chrome and Safari -- and I've gotten the enter button to work before with some stock code, but here's the catch: when the user presses enter, i want the focus to leave the input box. I don't care where it goes (submit button, I suppose?) but i need it to leave the input field so the onfocus="clearText(this);" event can fire when they return to type in a new income.
<script language="javascript" type="text/javascript"> function TotalGrossPerYear() { var Calc = document.NetIncome; if (Calc.InputRad[0].checked) {
If my php variable, (which is retrieved from a mysql table in the php code, not shown) is equal to "1", that means the member is not eligible to submit the form, so I want an alert() to say "member not eligible!". Else, I want it to continue to submit the form. Here is my code (which I can't seem to get to work):
<head> <script src="js/jquery-1.4.2.js" type="text/javascript"></script> //this first script is for something else, to check the max length of characters in a text area <script type="text/javascript"> function ismaxlength(obj){ [Code]...
I'm trying to create a text field that, when two or more characters are entered, the form is automatically submitted. The trouble I'm having is knowing when the onSubmit handler is fired. It's supposed to be executed when the form is submitted. I'm doing a submit via JS which should cause the form to run the onSubmit handler. But, it isn't. This leads me to believe that calling submit() is different from a hard submit. True?
Before submitting the form I want the user to bu sure that he ha completed it exactly. Sometimes people click ENTER button just t continue the fill next part of the form but when we clic ENTER,unfortunately, the form is submitted directly.
So I have written a function verify with javascript.
As following it works correctly:
onsubmit="return verify()"
So that the user needs to accept that he is OK to submit the form.
But when I added some required parts in the form that should b verified the first fuction verify is no longer active.
So how can I verify both required parts in the form and that the use is OK to send the form?
The code above has the value "Skype" and only after hitting Enter/ Return key, the value is submitted. How can the value "Skype" be submitted automatically without pressing Enter/Return key?
i am simply trying to call two function in an onsubmit. i have two functions on is located in the header and the other after the closing form tag, one validates radio buttons whilst theo ther validates dropdowns, text boxes etc. however i can only get one function to run.
