I made a input checkbox that contains array values. so it generates plenty of rows in a table.
But it needs for me to check it all to submit.
It doesn't allow me to check only few not all.
<form>
<table>
<td>
<input required="required" type="checkbox" name="id[]" id="id" value="<?php echo $result2["id"]; ?>"/>
</td>
<input type="submit" name="submit" value="submit"/>
</table>
</form>
How can i make the required field able to check atleast one and able to submit even if not all are checked?
I dont know if I understand you,
but maybee you need something like this:
Online demo
Main part with notes:
$('#frm').bind('submit', function(e) { // set this function for submit for your formular
validForm = true; // default value is that form is correct, you can chcange it as you wish
var n = $( "input:checked" ).length; // count of checked inputs detected by jQuery
if (n != 1) { validForm=false; } // only if you checked 1 checkbox, form is evaluated as valid
if (!validForm) { // if result of validation is: invalid
e.preventDefault(); // stop processing form and disable submitting
}
else {
$('#echo').html("OK, submited"); // ok, submit form
}
});
You can use any number of comboboxes under any tag and get count of selected by jQuery, then use any rule for validate form.

I'm trying to create a script that keeps our main button disabled until specific field requriments are met.
jQuery(document).ready(function() {//check if all are filled else disable submit
var inputFields = jQuery('#list-item-cc input, #field_28_50 input,#field_28_18 input');
inputFields.keyup(function() {
var empty = false;
inputFields.each(function() {
if (jQuery(this).val().length == 0) {
empty = true;
}
});
if (empty) {
jQuery('#gform_submit_button_28').attr('disabled', 'disabled');
} else {
jQuery('#gform_submit_button_28').removeAttr('disabled');
}
I'm having trouble thinking of a way to ensure my inputFields variable can be passed to my inputFields.each(function() in a way that would allow the loop.
We're not worried about all input fields. Just the specific inputs in our inputFields variable.
Is this an effective way to ensure a button is disabled if certain fields are not filled out and can I create the selector in the way that i did and use that in an each statement?
Looks like you are using gravity forms? In that case I would add a css class to each field that you want to validate. That way you don't have to go searching for ID's and change the code for multiple forms.
https://docs.gravityforms.com/css-ready-classes/
Here is a fiddle in which I pretend that I added "ensure-filled" to each item in the gravity forms builder
https://jsfiddle.net/dokLz4hm/3/
Also note that I added a .trim() to the value so that blank spaces aren't counted as input and made the submit button generic so it would work with any field in a form that contains the ensure-filled class
Html
<div>
<div id="arbitraty_id_1">
<input type="text" class="ensure-filled" />
</div>
<div id="arbitraty_id_2">
<input type="text" class="ensure-filled" />
</div>
<div id="arbitraty_id_3">
<input type="text" class="ensure-filled" />
</div>
<input type="submit" value="submit" disabled>
</div>
JS
$(document).ready(function() {
var inputFields = $('.ensure-filled');
inputFields.keyup(function() {
var empty = false;
inputFields.each(function() {
if ($(this).val().trim().length == 0) {
empty = true;
}
});
$('input[type="submit"]').attr('disabled', empty);
})
})
I have this form when information is being store into DB. I have a checkbox and a text field. Either one are required, but if the text field isn't empty, there's a good chance the checkbox should be checked. So I'd like to display an Alert if the Text Field has a value in it, and the checkbox isn't checked. I'd like this alert to appear when hitting the Submit button. Here's my form:
<form id="form" name="form" action=?post=yes" method "post">
<input type="checkbox" name="close" id="close" value="Yes"><label for="close" title="Close this RMA">Close this RMA</label>
<label><input type="text" name="dateshipped" id="dateshipped"/></label>
<button type="submit">Save and Continue</button>
</form>
So if checkbox "close" IS NOT checked AND "dateshipped" IS NOT NULL, then display alert when click Submit.
Thank you.
you can do a javascript function to be called on the onclick event in the submit button , like this
<button type="submit" onclick="callAfunction();">Save and Continue</button>
and define the function
callAfunction()
{
//do the checks with: document.getElementById('close').value
// display an alert("a message");
}
Would something like this work?
onsubmit="return validate();" // add to your form tag
function validate() {
checkbox = document.getElementById('myCheckbox').value;
if (!checkbox) {
alert('checkbox is empty');
return false;
} else {
return true;
}
}
Something like this perhaps?
Button for submitting. It runs validateSubmit. It only submits if the function is true.
<input type="button" value="submit" onsubmit="return validateSubmit();" />
Here's the validate function. It gets the value of the checkbox and the text. If they're both falsy then it sets valid to a confirm box. The confirm box allows the user to select ok or cancel and returns true or false based on that.
function validate() {
var valid = true;
var checkbox = document.getElementById('checkboxID').value;
var text = document.getElementById('textBox').value;
if(!(checkbox || text))
valid = confirm("Checkbox and text are empty. \n Continue?");
return valid;
}
The condition could be written as (!checkbox && !text), however I find it simpler to read to only use one ! if I can. The rule is called De Morgan's law if you're interested.
If you're using jQuery, things become easier.
var checkbox = $('#checkboxID').prop( "checked" );
var text =$('#textBox').val();
Plus you can attach even handlers like this:
$(document).ready(function() {
$('#btnSubmit').on('click', validate);
});
Let me know if you have any questions.
** Following code working for me, At first you need to add a onclick="functionName();" then do the following code**
function myCkFunction() {
var checkBox = document.getElementById("close");
if (checkBox.checked == true){
alert('checked');
} else {
alert('Unchecked');
}
}
I want to check a form if the input values are empty, but I'm not sure of the best way to do it, so I tried this:
Javascript:
function checkform()
{
if (document.getElementById("promotioncode").value == "")
{
// something is wrong
alert('There is a problem with the first field');
return false;
}
return true;
}
html:
<form id="orderForm" onSubmit="return checkform()">
<input name="promotioncode" id="promotioncode" type="text" />
<input name="price" id="price" type="text" value="€ 15,00" readonly="readonly"/>
<input class="submit" type="submit" value="Submit"/>
</form>
Does anybody have an idea or a better solution?
Adding the required attribute is a great way for modern browsers. However, you most likely need to support older browsers as well. This JavaScript will:
Validate that every required input (within the form being submitted) is filled out.
Only provide the alert behavior if the browser doesn't already support the required attribute.
JavaScript :
function checkform(form) {
// get all the inputs within the submitted form
var inputs = form.getElementsByTagName('input');
for (var i = 0; i < inputs.length; i++) {
// only validate the inputs that have the required attribute
if(inputs[i].hasAttribute("required")){
if(inputs[i].value == ""){
// found an empty field that is required
alert("Please fill all required fields");
return false;
}
}
}
return true;
}
Be sure to add this to the checkform function, no need to check inputs that are not being submitted.
<form id="orderForm" onsubmit="return checkform(this)">
<input name="promotioncode" id="promotioncode" type="text" required />
<input name="price" id="price" type="text" value="€ 15,00" readonly="readonly"/>
<input class="submit" type="submit" value="Submit"/>
</form>
Depending on which browsers you're planning to support, you could use the HTML5 required attribute and forego the JS.
<input name="promotioncode" id="promotioncode" type="text" required />
Fiddle.
Demo: http://jsfiddle.net/techsin/tnJ7H/4/#
var form = document.getElementById('orderForm'),
inputs=[], ids= ['price','promotioncode'];
//findInputs
fi(form);
//main logic is here
form.onsubmit = function(e){
var c=true;
inputs.forEach(function(e){ if(!e.value) {c=false; return c;} });
if(!c) e.preventDefault();
};
//findInputs function
function fi(x){
var f = x.children,l=f.length;
while (l) {
ids.forEach(function(i){if(f[l-1].id == i) inputs.push(f[l-1]); });
l--;
}
}
Explanation:
To stop submit process you use event.preventDefault. Event is the parameter that gets passed to the function onsubmit event. It could be in html or addeventlistner.
To begin submit you have to stop prevent default from executing.
You can break forEach loop by retuning false only. Not using break; as with normal loops..
i have put id array where you can put names of elements that this forum would check if they are empty or not.
find input method simply goes over the child elements of form element and see if their id has been metnioned in id array. if it's then it adds that element to inputs which is later checked if there is a value in it before submitting. And if there isn't it calls prevent default.
I've got a form that has multiple submit buttons. One for changing data in a database, one for adding, and one for deleting. It looks like this:
<form action="addform.php" method="post" id="addform" onSubmit="return validate(this)">
<select name="listings" id="listings" size="1" onChange="javascript:updateForm()">
<!-- Here I have a php code that produces the listing menu based on a database query-->
</select>
<br />
Price: <input type="text" name="price" id="price" value="0"/><br />
Remarks: <textarea name="remarks" wrap="soft" id="remarks"></textarea><br />
<input type="submit" value="Update Database Listing" name="upbtn" id="upbtn" disabled="disabled"/>
<input type="submit" value="Delete Database Listing" name="delbtn" id="delbtn" disabled="disabled"/>
<br />
<input type="submit" value="Add Listing to Database" name="dbbtn" id="dbbtn"/>
<input type="button" value="Update Craigslist Output" name="clbtn" id="clbtn" onClick="javascript:updatePreview();"/>
</form>
There are actually more elements in the form, but that doesn't matter. What I want to know is, for my validation method, how can I check which submit button has been clicked?
I want it to do the following:
function validate(form){
if (the 'add new listing' or 'update listing' button was clicked'){
var valid = "Are you sure the following information is correct?" + '\\n';
valid += "\\nPrice: $";
valid += form.price.value;
valid += "\\nRemarks: ";
valid += form.remarks.value;
return confirm(valid);}
else {
return confirm("are you sure you want to delete that listing");
}
}
I assume there must be some way to do this relatively easily?
Why don't you set a global variable specifying which button was last clicked? Then you can check this variable in your validate method. Something like:
var clicked;
$("#upbtn").click(function() {clicked = 'update'});
// $("#delbtn").click(function() {clicked = 'delete'});
// ...
function validate(form) {
switch(clicked) {
case 'update':
break;
// more cases here ...
}
}
You can, for example, attach a click event to every submit button that will save a pointer to it in a variable or mark it with a specific attribute / class (it that case you will have to remove that marker from all other submit buttons in the event handler) and then in the submit callback you will know which one was clicked
I think it's easier to just use a click event on each button and handle it individually.
$(function() {
$('input[name=someName]').click(someFunc);
});
function someFunc() {
// Your validation code here
// return false if you want to stop the form submission
}
You could have a hidden field on a form and set the value of that field on clicking the button and then pick it up in your validation routine. You can use jquery to achieve this, let me know if you require an example.
You can use ajax submission with jQuery, you can try something like this:
$('form#addform input[type="submit"]').on('click',function(e){
e.preventDefault();
var current = $(this); //You got here the current clicked button
var form = current.parents('form');
$.ajax({
url:form.attr('action'),
type:form.attr('method'),
data:form.serialize(),
success:function(resp){
//Do crazy stuff here
}
});
});

Resetting a multi-stage form with jQuery
(31 answers)
Closed 9 years ago.
I am looking for a jQuery function that will clear all the fields of a form after having submitted the form.
I do not have any HTML code to show, I need something generic.
Can you help?
Thanks!
Note: this answer is relevant to resetting form fields, not clearing fields - see update.
You can use JavaScript's native reset() method to reset the entire form to its default state.
Example provided by Ryan:
$('#myForm')[0].reset();
Note: This may not reset certain fields, such as type="hidden".
UPDATE
As noted by IlyaDoroshin the same thing can be accomplished using jQuery's trigger():
$('#myForm').trigger("reset");
UPDATE
If you need to do more than reset the form to its default state, you should review the answers to Resetting a multi-stage form with jQuery.
To reset form (but not clear the form) just trigger reset event:
$('#form').trigger("reset");
To clear a form see other answers.
Something similar to $("#formId").reset() will not clear form items that have had their defaults set to something other than "". One way this can happen is a previous form submission: once a form has been submitted reset() would "reset" form values to those previously submitted which will likely not be "".
One option to clear all forms on the page, is to call a function such as the following, executing it simply as clearForms():
function clearForms()
{
$(':input').not(':button, :submit, :reset, :hidden, :checkbox, :radio').val('');
$(':checkbox, :radio').prop('checked', false);
}
If you want to reset a specific form, then modify the function as follows, and call it as clearForm($("#formId")):
function clearForm($form)
{
$form.find(':input').not(':button, :submit, :reset, :hidden, :checkbox, :radio').val('');
$form.find(':checkbox, :radio').prop('checked', false);
}
When I originally came to this page I needed a solution that takes into account form defaults being changed and is still able to clear all input items.
Note that this will not clear placeholder text.
Set the val to ""
function clear_form_elements(ele) {
$(ele).find(':input').each(function() {
switch(this.type) {
case 'password':
case 'select-multiple':
case 'select-one':
case 'text':
case 'textarea':
$(this).val('');
break;
case 'checkbox':
case 'radio':
this.checked = false;
}
});
}
<input onclick="clear_form_elements(this.form)" type="button" value="Clear All" />
<input onclick="clear_form_elements('#example_1')" type="button" value="Clear Section 1" />
<input onclick="clear_form_elements('#example_2')" type="button" value="Clear Section 2" />
<input onclick="clear_form_elements('#example_3')" type="button" value="Clear Section 3" />
You could also try something like this:
function clearForm(form) {
// iterate over all of the inputs for the form
// element that was passed in
$(':input', form).each(function() {
var type = this.type;
var tag = this.tagName.toLowerCase(); // normalize case
// it's ok to reset the value attr of text inputs,
// password inputs, and textareas
if (type == 'text' || type == 'password' || tag == 'textarea')
this.value = "";
// checkboxes and radios need to have their checked state cleared
// but should *not* have their 'value' changed
else if (type == 'checkbox' || type == 'radio')
this.checked = false;
// select elements need to have their 'selectedIndex' property set to -1
// (this works for both single and multiple select elements)
else if (tag == 'select')
this.selectedIndex = -1;
});
};
More info here and here
<form id="form" method="post" action="action.php">
<input type="text" class="removeLater" name="name" /> Username<br/>
<input type="text" class="removeLater" name="pass" /> Password<br/>
<input type="text" class="removeLater" name="pass2" /> Password again<br/>
</form>
<script>
$(function(){
$("form").submit(function(e){
//do anything you want
//& remove values
$(".removeLater").val('');
}
});
</script>
You can simply use the reset button type.
<input type="text" />
<input type="reset" />
jsfiddle
Edit: Remember that, the reset button, reset the form for the original values, so, if the field has some value set on the field <input type="text" value="Name" /> after press reset the field will reset the value inserted by user and come back with the word "name" in this example.
Reference: http://api.jquery.com/reset-selector/
I use following solution:
1) Setup Jquery Validation Plugin
2) Then:
$('your form's selector').resetForm();
function reset_form() {
$('#ID_OF_FORM').each (function(){
this.reset();
});
}
the trigger idea was smart, however I wanted to do it the jQuery way, so here is a small function which will allow you to keep chaining.
$.fn.resetForm = function() {
return this.each(function(){
this.reset();
});
}
Then just call it something like this
$('#divwithformin form').resetForm();
or
$('form').resetForm();
and of course you can still use it in the chain
$('form.register').resetForm().find('input[type="submit"]').attr('disabled','disabled')
Would something like work?
JQuery Clear Form on close
HTML
<form id="contactform"></form>
JavaScript
var $contactform = $('#contactform')
$($contactform).find("input[type=text] , textarea ").each(function(){
$(this).val('');
});
Simple and short function to clear all fields
