Regular Expression To Verify Integer Input
Nov 26, 2009What expression would I use to validate a field's data - that cannot be anything but an integer?

Convert Input Field Value To Integer?
Mar 3, 2010This should be simple, but it's not working for me! The relevant code is beneath. This code is on my html page directly under the input field:
input = document.getElementById('hiddenInput');
var inputInt = parseInt(input.value);
if (inputInt != 0) {
setClick(inputInt);
}
(I've tested it to make sure it sees the input object and that it has the correct value. It does call the setClick function appropriately, too.) This code is in a javascript file called in the <head> of the html page:
[Code]...
setClick() and resetAll() work great when I hook setClick() up to a link. When I try to grab the value from the input field, it doesn't even call resetAll(). I've assumed that it's a problem with converting the value to an integer, but I could be wrong. Does anyone have an idea as to what's going on?

JQuery :: Validation Plugin: Check If A Field Contains An Integer Not Equal To Zero?
Jun 14, 2010I have already done a number of things with Jörn's validation plugin and I'm excited about its features. But here is my question: how do I validate a field so that it fits the two following conditions: it should be an integer and should not be equal to zero? So, if a user enters "0", it should be error; if he/she enters "12.5", it should be error also; but "-3", "125", "40" are OK.

Integer Or Text 'document.write('integer')' To Variable In Another Script...
Jul 20, 2005First script, 'xxx.js' returns value 'document.write('integer');
So in HTML:

Can I get this integer or text 'document.write('integer')' to variable in

Verify Email From Email Input Field And Check If The Checkbox (I Agree Condition) Was Checked
Jan 17, 2009Heres 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.
Ask For Integer Then List Numbers To That Integer On Page!
Sep 13, 2006I am trying to learn how to do this one thing with JavaScript and can't seem to find anything on the internet. I have learned about loops and arrays and some other useful stuff. I've been looking for 2 days straight. I have gotten close though.
I am trying to have a textbox on the page and a button below it. A statement above the textbox should ask the user to enter a positive integer and then click the button. When the button is clicked the results from 0 to that number should appear below the button. Should look like this
please enter positive integer.

BUTTON1

I have been trying night and day for 2 days now and It's driving me insane.

How To Verify Webpage Exists
Jul 23, 2005I 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...
}

JQuery :: Verify If An Url Is Legit?
Jan 2, 2011I 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] 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 ?

Verify Contents Of A Comment Box
May 8, 2007I 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?
Verify That Field1 = Field2
Jan 16, 2003I 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...
