I need to get the value from outside the form. My gsp looks like this
<g:textField name="email" value="${someInstance?.email}"/>
<input type="button" id="checkEmail" class="button" value="Validate" onclick="checkEmail()"/>
<span id="responseDiv"></span>
<g:form action="save">
someCode
<g:submitButton disabled="true" style="color:#999999;" class="save" name="save" action="save" id="saveButton" value="${message(code: 'default.button.save.label', default: 'Submit')}"/>
</g:form>
First, to check if an email is in use, click button (id="checkEmail") and onclick goes to js code checkEmail() which has remoteFunction that updates responseDiv. After that, user enters information to the form, and user clicks submitButton. When that submit button is clicked, I would like my gsp to send email value along with other information to the controller. Any suggestion?
Thanks in advance.
Easy, put the input inside the form.
If that isn't an option for some reason, use the callback to update a hidden field inside the form with something like $("#hiddenEmail").val(emailAddress);
PS. I like how you gave a span an id of responseDiv :)

hope You all have a great day.Here I'm trying to create a form without submit buttons,but when press enter on the text-box the whole text-box gonna hide.why is this is happening?,is it actually possible to create a form without a submit button or is that is a mandatory thing?,thanks for Your valuable time.
<form >
<input type="number" name="cbarcode" id="cbarcode" autofocus/>
</form>
When you hit 'enter' it submits the form.
I believe this is a natural part of a 'form' behavior for accessibility. Input inside of a form is meant to be data the user sends or inserts somewhere which is likely the reasoning behind this.
You can add to the Html form onsubmit="return false" or return preventDefault() as an event handler / function with other handling code you may want to provide.
Try this:
<form onsubmit="return false;">
<input type="number" name="cbarcode" id="cbarcode" autofocus/>
</form>
I have a simple (mostly-working) submission form:
<form action="http://127.0.0.1:3000/books" method="POST" class="addBook">
<input type="text" placeholder="Title" name="title" required>
<input type="text" placeholder="ISBN" name="isbn" required>
<button id="submitBook" type="submit" onclick="addingBooks()">Submit</button>
</form>
My form properly adds the input values to my database and it then appears in the DOM when I go back and refresh the page.
I have applied an preventDefault() function in my JavaScript code for the 'addingBooks()' function to stop it from submitting twice, but I am still unable to stop it from forwarding to the action page after submission which only shows the JSON of the submitted data.
If you need more then please let me know.
To prevent the default action of an event you'll need an event object to call preventDefault on. Some browser do in fact have a global event object but that might not be reliable.
The simplest option would be to return false from the onlick event, not from a function you call in it
<button id="submitBook" type="submit" onclick="addingBooks();return false;">Submit</button>
another simple and better solution would be to make the button be a regular button instead of a submit button and remove the preventDefault from addingBooks.
<button id="submitBook" type="button" onclick="addingBooks()">Submit</button>
another and even better solution would be to not use the onclick attribute at all, use the addEventListener function
document.getElementById('submitBook').addEventListener("click", function(e){
e.preventDefault();
//other stuff
});
Seems like a common question but could not find on this site. Must be due to my lack of experience in jquery or ajax.
I have a form like this:
<form id="form1">
+Add Item
</form>
when the person clicks "+Add Item" it pops up a new page which allows him to navigate and click the desired checkbox. Then it should insert in the above form something like:
<input type="hidden" name="item1_id" value="4">Item 1<br>
where value="4" would be the id of the checkbox checked.
any help would be greatly appreciated.
Don't use an anchor tag. Instead, create a div container for your pop up, which you can load dynamically:
$('#container').load('add-item.php');
Then add a listener to your item buttons append the result in your form:
$("#item_1").click(function() {
var $newinput = $("<input type='hidden' />");
$newinput.val(4);
$newinput.attr("name","item1_id")
$("#form1").append($newinput,"Item 1<br>");
});
In IE 7 the zip code search form on my page reacts differently when someone clicks submit vs pressing enter. It works correctly when sumbmit is clicked and incorrectly when enter is pressed.
http://getridofit.com
<form name="zip" action="<?php bloginfo('url'); ?>" method="get">
<input type="text" id="zipper" name="locations" size="5" maxlength="5" class="junk-input" onsubmit="return checkForm()" />
<input type="submit" value="" name="schedule" src="/wp-content/uploads/remove-my-junk.png" align="center" class="junk-button" style="background: #f67a3e url(/wp-content/uploads/remove-my-junk.png); border: none; width: 201px; height: 45px;"/>
</form>
The correct result for a zip search of 85718 looks like this: http://getridofit.com/l/85718/?schedule
but pressing enter produces a result like this: http://getridofit.com/l/85718/
Because the button wasnt clicked in order to submit the form. If you dont click the button then the input for #name[schedule] isnt sent. However if that button input has focus when enter is pressed i think it will send it along properly... You might jsut want to make schedule a hidden input.
It looks like you are checking for the presence of the submit button variable (schedule) in the URL bar. The submit button variable is only supposed to be submitted when the user physically clicks the the submit button. However, I can't reproduce the problem in Safari, so it may also depend on what your JavaScript is doing when the form is submitted.
I have a piece of code like this.
<form method="get" action="{$self}" name="addcommentform">
<textarea title="{$enterComment}" name="comment" class="commentarea" </textarea>
<input class="Button" type="submit" value="{$postComment}" />
</form>
How do I keep track of when what is the text entered in the form's textarea when the user navigates away from the page? I want to prompt the user with a warning message so he/she doesn't lose the text.
Thanks.
You could use the javascript/jquery blur event, and if the user hasn't clicked the desired button have it display the form values. This might help JQuery Blur Validation Problem

Take a look at this Javascript code snippet:

This takes advantage of the window's onbeforeunload event which fires when the user is about to leave the page.
