Verify Contents Of A Comment Box

May 8, 2007

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?

Analyze The Contents Of A Textbox And Replace The Contents With The Appropriate Date?

Jul 15, 2009

I'm looking for javascript to analyze the contents of a textbox and replace the contents with the appropriate date. To make that a little clearer, if the user types 'tomorrow' then when they tab/move onto the next text box the 'tomorrow' text should be replaced with the date for tomorrow in the format dd/mm/yyyy, if the user enters '1 week' then the text should be replaced with the date in one week in the format dd/mm/yyyy etc.

How To Verify Webpage Exists

Jul 23, 2005

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...
}

How Can I Verify If A Page Is Loaded?

Jul 20, 2005

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.

JQuery :: Verify If An Url Is Legit?

Jan 2, 2011

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 ?

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...

URL Based Conditional Comment

Sep 1, 2007

I am trying to create a conditional comment scenario that is based on a web address. I am working with an ecommerce site that I want to put a nav menu promotion on all the pages except the home page. The system we are using only allows a post promotion to ALL or one specified URL.

I have tried everything I can think of to create a URL condition based comment but nothing has worked. I tried modifying the code below to change the if output to a variable comment tag and then write the variable further in the script with a document.write.

<SCRIPT LANGUAGE="JavaScript">
<!--
url=location.href
if (url=="http://www.sitename.com") {alert("Welcome To sitename")}
else {alert("welcome")};
// -->
