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 ?

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).

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.

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?

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...

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.)

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.

I've been attempting to use 1.4.1 but I'm finding that $.get() and .getJSON() callbacks fail. The XHR requests succeed. I can examine the full request in both Chrome and Firebug. However, the callback functions *don't* execute. To test, I tried the same url with both 1.4.1, 1.3.2, and via a raw XMLHttpRequest(). The last 2 requests succeed, 1.4.1 fails. //v1.3.2 WORKS, fails in v1.4.1 $.get('/topic/api/template/list', function(data){

Sorry but I can't get the very first tutorial to work. I put the custom.js in a test_jr directory in htdocs. I also put the starterkit.html file in the same directory. I copied the contents of jquery-1.4.4.min.js into a jquery.js file also in the same directory. Then I did the custom.js page shown here:
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("a").click(function() {
[Code]...
I tried clicking on the [URL] and I get the starterkit.html page. If I click on the "some link" it doesn't do anything. What am I missing? There are syntax errors in my editor starting on the line with the asterisks* Why is there an error there? It looks like it closes the click function?
