Verify That Field1 = Field2
Jan 16, 2003
I have created a registration script in PHP and want a JS feature embedded to tell the user that the 2 passwords they have typed "haven't" matched. If they are identical, then I want the registration to go through as normal, but if there is an incorrect match, then it should stop the script and open up an alert box stating the error. When the user clicks on the "okay" button in the alert box, the script should not try to carry on with the process.
I have seen this feature on a number of registration websites, but I have searched Hot Scripts and some other resources to no avail...

This is my function
function func_name(){
if (field1.value == '' && field2.value == '' && field3.value == '' && field4.value == '') {
alert("All fields are empty.");
} else {
if (field1.value != '') {
if (field2.value != '') {
if (field3.value != '') {
if (field4.value != '') {
alert("All fields are not empty.");
} else {
alert("Field4 empty.");
}
} else {
alert("Field3 empty.");
}} else {
alert("Field2 empty.");
}} else {
alert("Field1 empty.");
}}}
If I set all fields to be empty, the alert display "Field1 empty.".

I have this web form that I want to validate only four of the fields (these are just input text fields, one of which is for e-mail). The code is supposed to bring up an alert box when a fields is empty and after the user clicks ok puts the focus on the offending input field. For the e-mail box, it is supposed to also check for correct e-mail address form.
While testing the first field, the alert text box appears, I click ok but the page sends the incomplete form to my processing page and causes and error. Firebug says that "field1 is not defined". Honestly it looks like it is defined to me. Can any of you take a look at the code below and see what I am doing wrong? Only my JS code appears below. I've searched online for possible solutions, but the things I've tried produced similar undefined errors. I admit I need more practice in JavaScript (familiar with JS, not proficient)
[Code]...

In a FrontPage web I'm trying to validate an email address to be sure it
meets some minimum format, perhaps something like ?@?.* I was told that
this could be done in javascript. Any help would be very much appreciated.

I have the following script that auto-submits a form at intervals.
setTimeout("document.forms['pageReloader'].submit();",90000);
Unfortunately, sometimes the target webpage is not available and I get
"page not found". That immediately kills my application, until I manually
restart it.
Is there a way in javascript to first check if a link exists before the
form is submitted?
For php programmers, an example of what I want will be:
if(fopen("http://www.example.com/", "r") {
do something here...
}

I have created two pages, the first page is stored in a free public web
server, and the second one is stored in a personal computer. This computer
is not allways on, so, sometimes, the page could not load.
I want to create a "Zero" page that checks if the second page is accesible
(and if it is, then redirect). And if the page is not accesible then
redirect to the public server.

I want to test a url the user gives to my website. All I want to do is check if the url is correct and live on the internet.
So I mainly be interested on finding out how to send a get ajax request and get back the http status code meaning either 200 success or a 404 error.
All I want to do is prevent something like this to be submitted to my website:
[URL] not a real site....
[URL] a real website.
I don't want to accept input of websites that don't exist or isn't currently live.
How can I test the url ?

has to do the verification. Will this work? What is the best way
to do this? Code:

I have a form with a javascript form validator to check against all fields to make sure they are entered in correctly and to reduce spam. I am using
Code:
var allowedChars = /^[a-zs]+$/i;
to specify that I only want characters and so on. Is there a way to reverse that to say this html input field CAN NOT contain any of the following? I want to check against a comment box to make sure no url address is entered (http:www.) because most spam contains urls in this field. Is there a simple solution?

What is the standard practice to verify that a page has loaded succesfully
in a frame when one issues a framename.href="url"? For example, detecting
404's, or other errors (like domain doesn't exist).

What expression would I use to validate a field's data - that cannot be anything but an integer?
An empty field is also invalid, or one with a space in it.

I use the following to verify that a user has entered a number between 0 and 99 in a form:
It seems to work fine in all browser / machine combos except Firefox on a Mac, when entering 0 returns false (I don't know if entering other numbers also returns false.)

I was wondering if there was an easy way to dump the html that gets generated after the page gets loaded to verify it's what I wanted and expected (I'd like to check out the source, not just the results).

Doing web page with ASP/VB.NET. Have text boxes for UI on page. Two command buttons - Submit (for db update) and Cancel. I need the Cancel button to prompt the user to verify cancellation. Need OK/Cancel buttons on alert. If user selects Cancel-no action. If user selects OK then I want the text boxes cleared of user text input and focus returned to first text box. I think this may be the code but do not know how to apply it.
function Clear()
{
var res=window.confirm("Please confirm cancellation-text boxes will be cleared"); [code].....
Is this code valid or invalid for the events I need? How do I set it to fire when user clicks the ASP Cancel button?

Heres my javascript code that will verify email from email input field and check if the checkbox (I agree condition) was checked:
[Code]....
However, this will work fine when calling with a link "javascript:validate('inputForm');" but if I try to prevent users by submitting form with pressing enter I put it in form onSubmit parameter: <form .. onSubmit="javascript:validate('inputForm');"> which will check the forms and submit data (do return) no matter if it matched or no.
