Could you please advise which event I should write in code for of type submit. Is it click or submit. I know that submit should be put for form. If button submit put inside in form I may write
$('form').submit()
is's for case of pushing button enter on keyboard.
If push button of the form should I write in code
$('button[type="sumbit"]').click()
I am working on a form with multiple fields and of course, a submit button.
How do I cancel the form submission if some fields are empty?
I tried putting a validation of javascript, input type="submit" onclick="check()" on the submit button.
But what I actually want is that, the page won't load so that, all other information in the text fields won't go away.
Like, what if the form has 100 fields and the user forgot to input one field and click the submit, it will show him an error message and all other fields will be cleared so he has to type it again.
I'm trying to prevent that.
I have multiple options to create this effect but I am currently trying to find a way on doing this.
Any other ways would be appreciated (like disabling the button when all mandatory fields are not filled, then enabling it at when everything is complete)
if the condition will be false click(event) returns false and nothing will happend
function check(){
if(validate === false)
return false;
}
Enjoy :)
You can simply return false from inside your check function to prevent the form from submitting.
I want to have a form on the main section of my webpage with buttons along the bottom of this section to submit it.
I also want to have a side bar with links to other pages, but make it so that whenever a link is clicked it acts as a button to submit the form too. (ie in the HTML, the code for these links will be outside of the form tags, but I would like them to still act as buttons for the form)
Is this possible?
You can solve this very easy without JavaScript in HTML5:
<input type="submit" form="id_of_the_form" value="Submit">
<form id="id_of_the_form" action method></form>
And you can style those buttons as you like. As in the example, the button can be placed at any point within the dom - no need to put it into the form.
Use the following onclick handler in your link, replacing formId with the ID for the form you want to submit...
onclick="document.getElementById('formId').submit();return false;"
Update
As #Juan (and others, especially #JoeTaylor) have mentioned, the above will not fire any client-side validation code associated with the form. The easiest way that I'm aware of to make it do so is to fire the click event of a submit button within the form. For instance, this could be used on your link...
onclick="document.getElementById('formSubmitButton').click();return false;"
Although you don't mention anything to do with server-side processing, I will take the assumption that is the point of your form. One additional thing I would say on the back of this is that you should ALWAYS replicate the validation back on the server. JavaScript is very easy to bypass, and so you should make sure the values reaching your server are correct, and never assume the JavaScript has done it's job.
The easiest way to ensure your form is submitted and validated by whatever function you've attached is not to call the form's submit() method, but to call its submit button's click() method instead.
Consider the following form:
<form id="bar" method="post" action="/echo/html/">
<input type="text" id="foo" name="foo">
<input type="submit" value="Submit">
</form>
Right now, clicking submit doesn't do anything special. But what if you wanted to ensure the text input had a value before sending anything off to the server? You might accomplish that as follows:
function validateBarForm() {
var txt = this.querySelector("input[type=text]");
if (txt.value == "") {
txt.style.outline = "solid red 2px";
return false;
}
}
document.getElementById("bar").onsubmit = validateBarForm;
Now if you click submit the form won't be submitted with a blank text input. But what if you submit the form programmatically? Let's add a link first...
submit form
Note that this link is outside of the form tag. We can trivially attach a submission function:
function submitBarForm() {
document.getElementById("bar").submit();
}
document.getElementById("submit-bar").onclick = submitBarForm;
We click "submit form" and... Whoops! The validation function is not performed! There are a few ways to skirt this issue, but my favourite is to simply have JavaScript simulate a click to the submit button. I find this holds up to changes a lot better than hardcoding a call to the validation function.
function submitBarForm() {
document.querySelector("#bar input[type=submit]").click();
}
Now when you click the link, the form is validated, and if everything checks out it's submitted too. But don't take my word for it--head on over to jsfiddle.net and see for yourself.
By adding an onclick javascript function to your form.
document.forms["myform"].submit();
Where "myform" is the id of your form. Here's a nice walkthrough: http://www.javascript-coder.com/javascript-form/javascript-form-submit.phtml
For example, the button might be:
<button onclick="document.forms['myform'].submit();">Hi</button>
Yes the button's click event add document.getElementById('formId').submit();
<form name="myform" action="action.php">
// Your form
</form>
Submit form
Or you can use jQuery:
<form name="myform" action="action.php">
// Your form
</form>
Your text
I do this myself with hidden submit buttons in the actual form, and outside of the form - anywhere else on the page - labels that reference the submit button and fire it.
In the form:
<input type='submit' id='hiddenSubmit'>
And anywhere else:
<label for='hiddenSubmit'>click me!</label>
Seems to do the job.
How can I get the data that is submitted from a form with jQuery?
I know I can bind the submit function to the form
$('form').bind('submit',function(){});
and I know I can serialize the data in the form:
$('form').serialize();
But how do I get the data that was actually submitted from the form? Like if there are two submit buttons, I want to know which one was pressed. If I handle the submission with PHP I can do that, but ideally I want to get a copy of the submitted data, then return true so that the form goes on to be processed by PHP normally.
Thanks!
The pressed submit button should be available in the serialized field list - and the other submit buttons shouldn't be in there.
However, apparently jQuery does not add submit buttons in there (testcase). See http://forum.jquery.com/topic/submit-event-serialize-and-submit-buttons-get-the-button-name for a workaround.
I have a form element I want to use in many forms, a standard submit button.
<div dojoType='dijit.form.Button' type='submit'
iconClass='dijitEditorIcon dijitEditorIconRedo'
style='float:left;margin:0 2px 00;padding:0;'
onClick=\"filter{$this->_grid->getId()}(); return false;\">Refresh
</div>
Current, this submit buttons works when clicked on, but the form does not submit when the enter key is pressed. Others have suggested a custom onkeypress event handler to submit the form when it catches the Enter key, but I'm hesitant because I don't want to break other forms on the page.
Stuff that you want running on form submission should be on form onsubmit, not a particular button.
