i have an if structure checking to see of the fields have been filled in.
On the text fields though there is no value so how can i check to see if nothing there which would mean aint been filled in.
i tried
if(variable = ""){
bla bla bla ..............
}
doesnt work,
I'm using JQuery 1.3 and was wondering how to check if at least one checkbox on my page is checked where each checkbox looks like this ...
<input type
="checkbox
" value
="####
" name
="x_invoice_num[]
" />
where "####" varies between the checkboxes.
What it needs to do is when the user fills in the last <input> it will add another one bellow it, and if it gets emptied it then removes the one bellow is (as long as it is empty too)
<input type='text' name='kit_parts[]' />
Thats the line it needs to add.
I'm have a Joomla component who use Jquery for several thing in his template. This component have a form where some field are displayed and I would like conditionnaly restrict the use of 2 fields. I have in fact a field "City" and a field "Zip code" and my goal is to disable one field if the other is filled. In practice that mean if a user start to type the name of a city, the zip field must be disabled for avoid to fill also this field. Same thing if the user start to type in the zip field...the field City must be disabled too..
I need to setup this because the search engine of my component can not retreive correctly data if both field are filled. This happen tipically if the the zip code don't match with the name of the city... I that case the component will display "no result found" and this is annoying. Any example of working code making possible to get this function? Unfortunately I'm not a coder and except html and a bit of css, I do not have enough knowledge..
Basically, I've setup a form to have all the required data written to a csv file. Now, The only thing is some of the non-required fields are filled in and some people don't fill them in, so when I import it into excel, the fields move about. What I need to know, is there a condition I can set to have a value written into all the empty fields when it is submitted?
Here is where I am with that so far:
if (app100.address2.value == "") {
doc.write("N/A");
}
What I am wanting to do is have my form open up a new part of the form when the previous sections are filled out. i.e name field shows, when it has content, the next field opens up for it to be filled out, and so on.
View 3 Replies View RelatedI have a form (form1) to register with the fields: user, email, password being validated normally.
Have a second form (Form2) to the user update the data registered in form1, and the fields user, email, password is already populated with data from the database, the email field I use the remote validation, and as the field already has been completed and read always says that this email already exists, how do I create a rule or method so that when the field is already filled it not do so validating and validate if it is filled with a new email. Email2 have a hidden field in order to do a test type.
If I want to hide a title / heading if a field below is not filled in, what would be the js for that?
I have an "Attachments" h2 heading and three following fields for the client to add up to three attachments. But if none are filled in I want the h2 heading to not display.
This is what I have so far:
This should take care of the three fields, but how do I tie in the heading too?
I'm having some problem with checking with the follwoing code:
if (appForm.q15a[i].checked==true && appForm.q15cert.value==""){
alert ("You must enter value!!!!")
valid = false;
}
What I'm trying to do is have the user enter some data based upon if
the radio button is true and the text field is empty. What could be
wrong with the following code above.
I have the following hidden field within a form:<input type="hidden" name="test12" value="test12" />I also have the following function which does something if that field exists:
if(document.formName.test12.value == "thisdata")
{
//do something
[code]....
<html>
<head>
<script type="text/javascript">
function convertHaH()
{
var mylist=Number(document.getElementById("percent"))
document.getElementById("remainder").value=100-mylist.value;
}
</script>
</head>
<body>
<form>
First percentage:
<input type="text" id="percent" onchange="convertHaH()">
<p>Remaining percent: <input type="text" id="remainder" size="20"></p>
</form>
</body>
This code works great, it will populate the second box. But I would like it to check if what was entered is a number if it isn't then an alert box shows stating they need to enter a number between 1 - 100, else it populates the second box.
My Javascript doesn't display an error when the "bid" field is blank but I want it to.Everything else works okay but I'm not a Javascript programmer so I don't know where to begin.
function checkBid(fieldName,minValue,maxValue){
var numberfield = fieldName;
if (chkNumeric(fieldName,minValue,maxValue) == false){

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 am doing some basic form validation stuff and I have two fields (phone, fax) that I need to check if the characters enterred are numeric, but still allow + and () characters to be enterred. If anything else has been enterred to display an error message.
Can someone point me to a resource ( I searched, but couldn't find an obvious one!) or give me a rundown on some code here to help me out?
Is there anyway I can check if the cursor is an input field? I need a function that determines if the cursor is in any input field on the page.

Okay, new to this magical thing called Javascript and LOVING it. Don't know how I avoided it all these years. :thumbsup:
Running into a stupid issue and I am sure it is just something I am missing. I have a hidden field in my page with the default value of HELLO. I am trying to make a change based on the default value, but I obviously am doing something wrong because it won't display my hidden field value. [code]...
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.

How can i check if file form field has file selected or is empty?[code]...
is this ok or is there a better way?
I have a shopping cart with a quantity field. I also have an update button that updates the totals. Myquestion is how can I use jQuery to check the quantity field when it loses focus, to check the value against the database and the Instock field. If gt then display a tooltip (or something) and not allow the form to be submitted. The problem is the field is called sel_qty for each product.
View 1 Replies View RelatedIm trying to pass fields to a javascript function that will check the value of each field and it its empty then it will turn the field color red which is what its doing at the moment, but i want to be able to use this function globaly through out my project, so is there a way of not saying how many fields go in to that array, it will just deal with the amount of fields it gets passed?
View 8 Replies View RelatedI would like to disable a feature on my site if someone is in a textarea or input text field. Yet I can't seem to figure out how to check for this... 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 having trouble with some javascript code that checks the first 2 letters of what the user inputs and whether it equals a certain set of characters. If the user for instance types in 'TT' in an input field, then i want the holding div to disappear, if anything else is typed in then this action wont happen. My code is below:
Code:
<script type="text/javascript">
function checkCode() {
var x=document.forms["myform"]["code"].value.substring(0, 2);
if (x == 'TT')
[Code]...
I believe the problem lies in the javascript line: "if (x == 'TT')", as the rest of the script responds but it just doesnt recognise whether 'x' starts with 'TT'
i'm fairly new to regular expression and want to know if it's possible to check a text field value. I need to only accept value between 0 and 20. I've got also a problem with the 0 value ... guess the script think it's false :
if(!Number(document.data.f_cat_1.value) || document.data.f_cat_1.value > 20){
alert('Your must enter a numeric value between 0 & 20 pts!');
document.data.f_cat_1.focus();
return false;
}
