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 am working on a registration page.I did all the validation but facing problem during username validation.when a user enter email id in the textbox,it first check whether it is present in database or not.. if not present "register successfully" otherwise "email exists"
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 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'm working on a script that needs to check if a window is open. The window is opened from a different function then the one that 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?
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...
It launches in IE and give the user instructions, then at the click of a button, launches my setup.exe. I want my webpage to launch setup.exe then go to another webpage on my CD, congratulations.html, which says "installation is complete etc". Here's what I am trying to do through JAvascript. It doesn't work. Should the first instruction be flushed in order for the 2nd one to work?
I want to use the values of text boxes on my HTML webpage to create a webpage URL (like below):
<script type="text/javascript">
My text boxes are as follows:
Now this all works and the result webpage URL prints to id='ID1', but the big question is how do I use this resulting URL in another Javascript section as the src="?
I am trying to display a webpage from another domain and tried to access its elements and I am facing issues with this.
I tried using "iframes" and am facing cross domain issues.
All that I want to do is, set and get the attributes of the elements of the webpage from the other domain (eg: set text field value, get dropdown box values, click button etc)
Is there a way to get this job done?
I thought of browser addons however it will be a browser specific 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).
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 want to verify that the data in my form in HTML is already exist in my database if this is true then the form must not be sent. I know this is done in javascript but I can not found the right solution. I would like an illustrative example.
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).
The following Javascript will return an error message if the user did not enter any value into the zip code field. The form will submit even if user entered only 1 character. Does anyone know how to change this to at least minimum 5 characters must be entered into the field?
...} var fname = "CustomFields_17_2"; var fld = document.getElementById(fname);
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?
Could anyone know the script code for a WEBPAGE ON TOP OF A WEBPAGE? The site was not working anymore, so I can't tell you the link. This is what I saw, When I visited the site (Mainpage) There's just a Welcome Image that shows CLICK HERE TO ENTER. After clicking the link, a loading faded icon appears on top of Welcome Image covering that Welcome Image with Webpages, it's like popping to the center of the page. I don't know if someone of you could understand me. It's like Page on TOP of another Webpage without leaving the 1st page.
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.
