How can i check if file form field has file selected or is empty?[code]...
is this ok or is there a better way?
When i select a file (through html file control) from local machine, before uploading i want to check if the selected file exist(because,after selecting and before submitting the form,user may change the name/delete the file from the source). so after selecting the file, i need to check the same file exist as it is using javascript/ajax. Back end is JSP.Eg: Am selecting abc.jpg from my system and changing the file name form the source as abcd.jpg, now abc.jpg does not exist. But i want to check if exist. If selected file does not exist, i want to display a message before uploading/submitting the form.

Could someone give me an example of how I can determine if a user does not have a text input or textarea selected? Can't seem to get anything I found via google working.
View 2 Replies View RelatedI am using jquery.validate.js for my validation. I need to validate some dynamic input fields. By using class now I am able to validate that. Here my problem is to validate for the file extension.
For static files I use as
file: {
required:true,
accept: "png|jpg",
},
How to write the accept validation for dynamically generated input fields. Below is my input field where the ID and name will change for every input field.
<input type="file" id="tval_1" name="tval_1" class="required accept" />
I found something here, but I'm not good at javascript, and i don't know which part of the code is the right! I need only for Checkboxes!
[url]
I need something like: onclick="check_if_at_least_one_is_selected()"
There is only one <form></form> and all checkboxes are same type...
Is there any way to use jquery.validate to check if any field from the form contain HTML injections?

Code:
function dateValidation()
{
var obj = book.dc1.value;
var day = obj.value.split("/")[0];
var month = obj.value.split("/")[1];

Is it possible to have a form's textarea background image fadeout to an alternate bg image, when that textarea is selected (by clicking the textarea or tabbing to it)? I've never seen this done before, but I'd really like to do it..

I have an image validation script that im working on. This is what i have so far...
<script type="text/javascript">
<!--
function validate_form ( )
{
var imgcheck;
valid = true;
if ( document.editavatar.avatar.value == "" )
{
alert ( "Please Enter an Image Url!" );
valid = false;
}
return valid;
}
//-->
</script>
How can i add to that so that it checks if the avatar field has the words png, jpg, gif and bmp, and if it doesnt, valid will be false. So in other words, if it does contain png, jpg etc it will return valid.
I have some problems with validating form in javascript.
I have a following HTML code:
What I want in validation is to check all the field in form (check for required fields etc). I want to show user error message in div tag with id='poruka'.
Part of code of function ValidirajFormu:
So, validation works OK, but message is not written in div tag. Only if all fields are correct, form is submited, but there are no error message.
I want to validate a form. In the form is a text field named 'extra[]' where the user inputs a number. The number is what I want to validate.
However, the 'extra[]' field is dynamic and does not always appear in the form.
If it appears, there may be only 1 occurrence of it which means it's then not an array but there may also be multiple occurrences of it.
I have a script that validates (and work as it should) if the 'extra[]' field occurs multiple times and is thereby an array, but I can't figure out how to validate the 'extra[]' if there is only 1 and to not throw an error if it's not there at all. Code:
A non leap year can be divided by 100. But a leap year is divisible by both 4 and 400.This seems so simple yet I can't nail it. I'm taking an accelerated Javascript class and I was able to do all the problems up to this one. It's confusing me, or it may be that I've been up since 2 working on homework and getting ready for another test.
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

lets say i have this form:
Code:
<html>
<body>
<form name="x">
<table>
[Code].....
what i want to do is have a selection from 'tst' trigger an input into 'choose' from the data inputted into the 'fname' and 'lname' fields.
for example, i want option '1', when selected to draw the input from 'fname' and place it into 'choose'
or i might want to select the data in 'lname' instead, so i will tie option 2 to it, so when the user selects option 2 the contents of 'lname' go into 'choose' instead.
I'm using a form on a page as a vessel for data, rather than to actually submit it. The reason is that the form is submitted to a service at www.rdbhost.com with it's special JS API, so I extract the data from the form manually and then feed the data to the methods from the provided library.
One of the field is a file. Calling ``.val()`` on it simply gives me the file name, but I need the contents.I've looked around, and found a few plugins that would actually send the file, but that's not what I want.
I have a form set up and I need to set the validation so if one option is selected from a picklist, they need to complete a text field as well.
This is the code i'm using:
Code:
Reason is a picklist, I want it to show the alert when option 1 from the picklist is selected and no text is in the Row_Number field.
If any of the other options are selected, I want to make sure the Row_Number field is blank.
As I said, I'm sure this is a very simple thing, but I been working on it for ages, and cannot get it to work, I get the alert every time the Row_Number field is blank.
I have a form with a text field and a submit button. I don't want the form to submit if the text field is filled in correctly. for example a email address typed in the text field area. I'm working with spry validation but i guess i need to add some kind of onSubmit event, with javascript. I have some idea but not sure what to fill in by the "if statements" in the script.
View 3 Replies View RelatedI'm having users fill out a form where there are multiple rows of data.
Some of the rows can have duplicate data for some fields.
So say on line 1) i have first name, last name as an input fields and some other fields as well, c, d, e, etc.
When the user gets to line 2) if they want to have the same first name and last name as line 2, can I have them check a box and it will automatically populate these fields with the info they just typed in line 1? I can't figure out how to do this.
actually there's no error in the code only that is only made to check for one input field and my form has 3 image upload fields, the original is:
<form enctype="multipart/form-data" action="action.php" method="post" onSubmit="if(!this.img1.value.match(/.jpg$/i)){alert('Must be JPG file');return false};return val(this)">
<input type="file" name="img1">
</form>
This works great but what modifications should have to be able to check multiple file input fields?
I'm using the following javascript code to validate a form:

The fact that my using xhtml strict I'm having an error when validating my html file. Can't use name attribute in form.
I'm stuck with this one since my knowledge of javascript is very low, PHP I'm ok with but this is a new language to me. Anyway, I have a form (a table-less one) which I would like to have the ability to add extra file fields if needed. One is already placed but I would like the user to have the option to add more photos. Here's my html:

how to put the jquery once file is selected, and not Cancel is selected.
Let's assume we have
<input name="title" type="text" value="- none -" size="33" maxlength="50">
<input name="filepath" type="file" size="33">
and at another portion of that page also have a similar repeated code as above.
I want to put some changes once the File is selected not when the button Browse is Pressed. Is there any work around?
I have a <input type = file> button for uploading a file in my php page. As soon as i select a file from the button, i need the file data to be displayed so that i check whether the file selected has the correct data. How can i do this.
View 1 Replies View Relatedis there a way to assign an event to a file input so that when a user selects a file to upload the event is triggered and i can check out the file extension? The reason why is simple, i want to perform different actions depending on the type of the file.
View 2 Replies View RelatedI have a form that gets values that a user has selected from a list menu field, that end up like this added to the URL:[url]
Instead of the Field being mentioned more than once, how can I have it where it could mention the field once with the values coma separated eg:[url]
Would I use JS to change the URL? or VBscript?
