Check Form Value Against Array?
Jul 19, 2010
I need to verify that the email address is not a free account. I will have an array that contains a list of free email providers. ie. gmail yahoo hotmail.I want to compare this list to what the user entered. and if there email address contains one of the values from the array then return false. I am a php dev so excuse the crude code.
Code:
var freeEmail=new Array("gmail","yahoo","hotmail");
if (form.email_address.value (contain a value from freeEmail) {
alert( "Please no free email accounts." );
[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:

I'm working a bunch of pre existing code on a CMS. Just after a quick fix. Doing a show/hide thing on a particular div somewhere on the page depending if a checkbox is ticked or not.Currently there is 3 checkboxes that are dynamically added through the CMS. Here's simplified version of the form:
<form id="simplesearch" name="simplesearch">
<input type="checkbox" onclick='showhidefield(this.value)' name="meta_data_array_search_criteria[custom_profile_type][]" value="5" class="input-

I have an .asp page for my customers which does just accepts e-mail information and passes this information to another .asp page. But before passing the info, a javascript checks whether the entered e-mail does match some certain rules. Rule1: If any input has been made at all, Rule2: If an "@" sign is there, if the"." is there and so on. upon pressing the submit button, the first rule works but the second rule does not. Could not figure it out why.
[Code]...
It is the function control() which validates the e-mail field. But it just validates whether the e-mail has been entered or not. The second check (with the @ sign) is not being made.

It's to allow users to create thier own descriptions, and the input is displayed automatically using innerHTML. This part of the function checks if the HTML tags are allowed through, I've got this far...
allowedHTML=new Array("<br>","<b>","</b>","<i>","</i>")
HTMLcount=allowedHTML.length
function formcheck() {
lettercount=document.formname.email.value.length
HTMLcheck=""
for(i=0;i<ltrcnt;i++){
if(document.prsnlsd.email.value.charAt(i)=="<"){openat=i}
if(document.prsnlsd.email.value.charAt(i)==">"){closeat=i+1
for(j=openat;j<closeat;j++){
HTMLcheck+=(document.formname.email.value.charAt(j))}
for(k=0;k<HTMLcount;k++){
if(HTMLcheck==allowedHTML[k]) return; else alert()}}}}}
I want it to trigger if one of the "allowedHTML" isn't found by the time it's finished going through the array.

I am working with a checkbox array where the key is already set. So instead of being able to use name="name[]", I need to use name="name[0]" etc.. I would like a button or a checkbox to select all in the array(name).
The main reason for this is the nature of the checkbox. If a checkbox is not selected then it is completely skipped when looping through the array. To overcome this I added a hidden field of the same name which will assign a value even if the checkbox is not selected. Then the problem of using name[] arises.
The form is populated with hundreds of entries using PHP so I am looking for a way to loop through them all.
Here's a tiny snippet of HTML of how my form is set up.

I'm looking for some guidance on a part of some coding practice I'm stuck on!
I've created a shopping cart using javascript, the items save to the arrays etc and it all works fine. If the user adds the same product again to the cart the quantity is added onto the previous quantity that is already in the cart.
To check if the item is already in the cart I've ued the below code, but what it does is update the quantity for the first cart, and when it updates the quantity for the second item it updates the quantity but keeps adding the same product to the cart in seperate elements of the array as well (if that makes sense?
here are the two functions used [code]...
It may jsut be a simple mistake I've made but it's been bugging me a lot and I can't seem to fix it.

I am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form.For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields.

So that I can pass multiple checkbox values to my PHP processing script as an array I added the square brackets to my form's checkbox input element's name, like this: <input type="checkbox" name="checkGroup[]" value="'.$rowIDs.'" /> Because it has to match, I updated the input element I use to check/uncheck all the checkboxes so that it now looks like this: <input type="checkbox" name="all" onClick="checkAll(document.ResIDsDates.checkGroup[],this)" />
When I manually select multiple checkboxes I can successfully pass any number of checkbox values through
the POST array to my process script...but my Check/Uncheck All box has ceased working -- adding the
square brackets to the checkbox input's name disabled it.
I tried playing with the ASCII equivalents to the brackets, but no go. Is there a way to retain the array
functionality and pass multiple checkbox values to the script AND enable the Check/Uncheck All box?

have an array of objects which is gAllMedicalFilesClaimantsArray which has 2 properties (UserID & UserInfo).
For example:
gAllMedicalFilesClaimantsArray[0].UserID = 111;
gAllMedicalFilesClaimantsArray[0].UserInfo = "AAA-123";
gAllMedicalFilesClaimantsArray[1].UserID = 222;
gAllMedicalFilesClaimantsArray[1].UserInfo = "BBB-333";
What is the fastest way to check whether a specific UserID exists in the array using Jquery or Javascript because gAllMedicalFilesClaimantsArray has got 8000 records?

I have a form where I click a button and it duplicates the inputs thus now having X of the same inputs. The input name looks like so:
<select id="select" name="cs_quantity[]">
Is there a way I can check the all values of the quantity before submitting the form? I want to make sure they've chosen a quantity other than 0.

I want to get the code ( I cant write it Im still a newbie ) to check a form user/pass and trigger another hidden form.
Heres what going on:
Have created a form, Form 1 Login: it has a username and pass fields. It shares the page with a Members Login form.
I want javascript to check the user/pass on Form 1 Login against a user/pass I assign. I assume I can assign one in the Javascript code.
The script does not send the form to the server, it just checks to see that the user/pass agrees with what Ive assigned.
The script, if the user/pass is the same as I assigned, triggers a Registration form to pop up that Ive hidden with CSS left:-999em.
Now the script has fulfilled its function, its done. But heres what continues and Adobe BC does this part.
User fills out the pop up Registration form with any user/pass, their valid email and name.
Clicks Submit and the form sends the New user a new personal pass and new username via email.
User adds New user/pass to Members form and is allowed into the site.
This is a round about way but, I can not use php or server side in this process, BC does not allow server side only client side. So Im doing a work around. I know someone could find the Javascript even in a js folder. Tight security is not an issue. I researched this for weeks and BC tells me it will work with their system...I just dont know how to write it.

How do you detect that a form element has been changed? This thread:
http://groups.google.com/group/comp...25a82c9be127790
suggests that you attach onChange event handlers to every form element,
and when the handler fires you update a global 'isChanged' variable.
This technique seems to be a bit messy to me (I have many form
elements), I was thinking about storing the original form object in a
javascript variable when the body loads (in the bodie's onLoad event
handler), and upons submission, doing a javascript equality comparison
with the current form object. If nothing has changed, then the two
objects should be equal, right?
if(oldObject == document.getElementById('form'))
{
alert('has changed!');
}
Would this work?
