I am trying to write some code where I have the pageA.html and pageB.html
On pageB.html I have a form:
<form>
First name:<br>
<input type="text" name="firstname" value="">
<br>
Last name:<br>
<input type="text" name="lastname" value="">
<br><br>
<input type="submit" value="Submit">
</form>
Both pages are on my localhost.
I need to add some code on pageA.html that with hit the submit button on pageB.html
Is this possible? If yes, How can I do this?
No, It is not possible by using only html. You have to use any server-side scripting language like PHP or C# etc.

I need to have a form with a button which on submit, check for required field but does not refresh the page.
<form>
<fieldset>
<input type="text" id="firstname" placeholder="First Name" required/>
<input type="submit" value="Send"/>
</fieldset>
</form>
If I disable on submit for form, it wont check for required fields anymore. I need all the functionality of onSubmit but without refreshing the page.
I will appreciate any help.
I'm unsure why you are getting an error. The code provided should work. Try adding an action and a method just in case as follows:
<form action="" method="POST" onsubmit="myFunction()">
<fieldset>
<input type="text" id="firstname" placeholder="First Name" required>
<input type="submit" value="submit">
</fieldset>
</form>
You can then add a function called myFunction down below as follows:
<script>
function myFunction() {
alert("Form was submitted");
}
</script>
I've got a problem regarding my contact form page. I did callback after clicking the submit button. I tried not to fill name textbox but form still submits.
My code:
function sendFeedback() {
alert("Thank you for the feedback :)");
}
<form>
<p class="font3">Name:</p>
<input name="name" type="text" maxlength="50" size="30" required/>
<br />
<p class="font3">Email:</p>
<input name="email" type="email" placeholder="" required/>
<br />
<p class="font3">Subject:</p>
<input name="subject" type="text" required/>
<br />
<p class="font3">Message:</p>
<textarea name="comment" row="80" cols="30" required></textarea>
<br>
<br>
<input type="submit" value="Submit" onclick="sendFeedback()">
<input type="reset" value="Reset">
</form>
You should change <form> to <form onsubmit="test()",where test() would go something like this:
test(e){
e.preventDefault();
/* do some validations here */
document.querySelector("form").submit();
}
Hope it helps
The form submitting and your alert triggering are two completely different things. The required attributes you have on the inputs are working correctly. If you leave any of the required inputs blank, the form will not submit to the server, instead you'll trigger standard error messaging in whatever browser you're using (usually a red outline and a popover).
The bit of JavaScript you have (i.e. your alert) will trigger regardless of whether the form submits successfully or not since it's executed BEFORE the submit goes through. You need to either do something like e.preventDefault() or return false at the end of your function, but that will prevent the form from being submitted altogether.
As #dvenkatsagar said, your best option is to change your onclick to onsubmit.
I have some comment forms that I want to not be used unless the user is logged in with Google+. I initially have the "submit" button on my forms hidden by the CSS display:none property. I call javascript when the user logs in to change it back to display:inline.
Is this a valid way to prevent anonymous users from posting, or am I still vulnerable by leaving the rest of the comment form open for writing and whatnot...is there some clever way to submit the form without the submit button?
<form action="" method="post" name="form1" id="make">
<fieldset>
<legend id="makelegend">Log in to Post a Reference</legend>
<input type="hidden" name="loginname" id="loginname" />
<input type="hidden" name="logintype" id="logintype" />
<input type="hidden" name="loginspecial" id="loginspecial" />
<input type="hidden" name="reply" id="reply" value="0" />
<input type="hidden" name="identity" id="identity" value="<?php echo htmlspecialchars($_GET['pageno']); ?>" />
<p><label for="posneg">Positive or Negative?
<select name="posneg">
<option value="p">Positive</option>
<option value="n">Negative</option>
</select></label></p>
<textarea name="comment" rows="5" cols="70"></textarea>
<input type="submit" id="submitter" value="POST" style="display:none;" />
</fieldset>
</form>
It is ABSOLUTELY NOT safe! You're just not displaying the data to the user, but anyone who looks at the code can still find it - or just send the request manually. I can't stress this enough: ALWAYS use server-side validation! It's fine to validate things in the browser as well, but it's not a substitute for proper security measures.
I am very new to JavaScript and web development in general. I have a problem when I want to have my log in system executes a JavaScript function when the user submits but it does nothing when it should print to the screen. I can't figure out exactly what I am missing. Any help will be greatly appreciated!
<form name="sign_in" onsubmit="check_stuff()">
<b>Username...</b>
<br>
<input type="text" name="Username" value="Your Username">
<br>
<br>
<b>Password...</b>
<br>
<input type="text" name="Password" value="Your Password">
<br>
<br>
<input type="submit" value="Submit">
</form>
<script>
function check_stuff(){
document.write("gametime");
}
</script>
The function is writing to the document, but that will just be visible for a very short time while the page reloads. The form will still be posted, so the page will reload and replace what you have written.
You would want to return the result from the function in the event handler:
onsubmit="return check_stuff()"
That will allow you to return false from the function if you want to keep the form to be posted:
function check_stuff(){
document.write("gametime");
return false;
}
(I assume that you are just using the document.write for testing purposes, as it will replace the entire current page with what you write.)
This works fine. Although it overwrites the DOM because document.write is called after it loaded. This means only gametime will be on the screen afterwards. It does show but, but submitting a form reloads the page. So it will appear as nothing happened.
To fix this you will want to return false; in which will not submit the form. Also change onsubmit="check_stuff()" to onsubmit="return check_stuff()".
It works ok for me, I think the issue you have is that te page is reloading after submit. Just add a return false; after the check_stuff() call to avoid the reload.
<form name="sign_in" onsubmit="check_stuff(); return false;">
Check out this codepen.
if you want current page not be redirected, you should submit your form to a iframe in current page, like this:
<form name="sign_in" onsubmit="check_stuff()" target="#frame">
<b>Username...</b>
<br>
<input type="text" name="Username" value="Your Username">
<br>
<br>
<b>Password...</b>
<br>
<input type="text" name="Password" value="Your Password">
<br>
<br>
<input type="submit" value="Submit">
</form>
<iframe id="frame" name="frame"></iframe>
<script>
function check_stuff(){
document.write("gametime");
}
</script>
I have two XHTML forms (below). I am looking for a way to submit the two forms with one submit button.
First Form Below
<form method= "post" action= "forum_add_111438076.xhtml" >
<input type= "hidden" name="d_token" value="2ab5b36d7d0e5f9fee88cc9a67553db6" />First
Name:<br/><input type="text" name="meno" maxlength="20"/>
<br/>Last Name:<br/><input type="text" name="text" maxlength="20000"/>
<br/><input type="submit" name="submit" value="Submit" /></form>
Second Form
<form method="post" action="forum_add_111438075.xhtml" >
<input type="hidden" name="d_token" value="d0cb19bc6b0d162a11431213976206b8" />
Phone Number:<br/><input type="text" name="meno" maxlength="20"/>
<br/>Address:<br/><input type="text" name="text" maxlength="20000"/>
<br/><input type="submit" name="submit" value="Submit" /></form>
Each form above has its own submit button, but I want to use only one submit button.
You cannot simultaneously submit two forms at once. (like one webpage cannot go to two)
One way around this would be to use Ajax and submit the forms one after another.
Some Example Code. (using jQuery)
HTML
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<form id="form1">
<input type= "hidden" name="d_token" value="2ab5b36d7d0e5f9fee88cc9a67553db6" />First Name:<br/><input type="text" name="meno" maxlength="20"/>
<br/>Last Name:<br/><input type="text" name="text" maxlength="20000"/>
<br/></form>
<form id="form2">
<input type="hidden" name="d_token" value="d0cb19bc6b0d162a11431213976206b8" />
Phone Number:<br/><input type="text" name="meno" maxlength="20"/>
<br/>Address:<br/><input type="text" name="text" maxlength="20000"/>
<br/></form>
<input type="submit" name="submit" onclick="submitAction()" />
Javascript
submitAction() {
$.post('forum_add_111438076.xhtml', $('#form1').serialize())
$.post('forum_add_111438075.xhtml', $('#form2').serialize())
}
It's not exaclty possible to submit two forms at once to two different places.
The best thing you can do, if you require seperate processing, is to use your receiving page to gather the secondary form post, and send that along to the secondary processing page. PHP using CURL is perfect for something like that.
If you use the get or an ajax function it will allow you to know when the first or second form is completed. Using the get you would use .done if you use ajax you will use the .success Once your first form has completed the submission, you can then submit your other form as shown below.
//Submit your First form
$.get("postOne").done(function(){
//When your first form is completed you can then submit your second form.
$.get("postTwo").done(function(){
});
});
