I have a form on my page that needs to have multiple form actions associated with it. I'm using the following script in conjunction with the following code to achieve this:
<script>
function submitForm(action)
{
document.getElementById('summary').action = action;
document.getElementById('summary').submit();
}
</script>
<form action="go-gold.php" method="post" enctype="multipart/form-data">
<input type="image" id="arrow" name="go_back" onclick="submitForm('go-gold.php')" value="go_back" src="images/arrow_back.png" class="submit_button" /><br>
<input type="image" id="arrow" name="submit_form" onclick="submitForm('registration.php')" value="submit_form" src="images/arrow.png" class="submit_button" />
</form>
The first button needs to "go back" within the same browser window (self), and the second button needs to submit the info to a new window (blank). How do I modify the code to achieve this? Putting "target" functions within the input type doesn't work, and putting the target in the Form tag makes both submit buttons submit to the same window.
Thanks!
Easy with jQuery, also you have to identical ids for two separate form elements. You should have these as distinct ids unless you want to use a class name. Php can submit forms to the same page using the $_SERVER superglobal by using $_SERVER['PHP_SELF'] as the forms action name.
<script>
$(document).ready(function() {
$(".submit_button").click(function() {
clickVal = $(".submit_button").val();
if(clickVal == 'go_back') {
//do go back stuff
}
if(clickVal == 'submit_form') {
// do actions for other page
}
});
});
</script>
<form action="go-gold.php" method="post" enctype="multipart/form-data">
<input type="image" value="go_back" src="images/arrow_back.png" class="submit_button" /><br>
<input type="image" value="submit_form" src="images/arrow.png" class="submit_button" />
</form>

I would like to stop default submission using Vanilla JavaScript. I created a sample of little form. But it gets refreshed when I submit the form even though I call the preventDefault() method. When I use input type="button" it works. But not works with input type="submit".
What will be the reason? Can anyone explain me what is the right method and what's wrong with the code?
My code is as follows:
let validation = () => {
let form = document.querySelector(".form");
form.addEventListener("submit", (event) => {
event.preventDefault();
});
}
<form action="" class="form" method="post" onsubmit="return validation()">
<input type="text">
<input type="submit" value="submit">
</form>
Optional Help: Can anyone give me a proper method or any good references on creating forms. Because when I search, I got lots of tutorials where all are says different methods and I really struggle to find out which method is the standard one.
Try the following changes to your code:
HTML
<form action="" class="form" method="post" onsubmit="validation(event)">
<input type="text">
<input type="submit" value="submit">
</form>
Try removing the return keyword and add event parameter.
JavaScript
const validation = event => {
event.preventDefault();
}
Using the preventDefault() method of event, the form is hopefully not submitted! Hopefully it works for you.
I have one doubt is it possible to have a single form(view page) with multiple actions like i want to save,update and delete on the same view page..if the user click on anyof the button then it have to call on a necessary controller function is it possible??
You have some ways to do it, but all of the them require some javascript code.
The easiest I can think of is to dynamically change the form action when clicking each button (of type button, not submit which is the default), and then submit the form.
Example:
<form id="myform" name="myform" method="post" action="">
<input id="myinput" name="myinput" type="text"/>
[..]other inputs[/..]
<button type="button" onClick="deleteAction()">DELETE</button>
<button type="button" onClick="updateAction()">UPDATE</button>
<button type="button" onClick="saveAction()">SAVE</button>
</form>
Where the JS functions are:
function deleteAction() {
changeActionAndSubmit('/action/delete');
}
function updateAction() {
changeActionAndSubmit('/action/update');
}
function saveAction() {
changeActionAndSubmit('/action/save');
}
function changeActionAndSubmit(action) {
document.getElementById('myform').action = action;
document.getElementById('myform').submit();
}
Hope I got your doubt and that this solves your issue :)
A non-JS way to achieve the same goal would be to use the name/value parameters on each button to have your backend decide what to do.
Example
<?php echo form_open('controller/method'); ?>
// form fields go here
<button type="submit" name="add" value="y">press to add</button>
<button type="submit" name="update" value="y">press to update</button>
<button type="submit" name="delete" value="y">press to delete</button>
<?php echo form_close(); ?>
then, on your controller, after validating user input, you can determine which button was pressed by reading what the buttons send about themselves to the controller (I'll assume you use CI's form helper)
if ($this->input->post('add') == 'y')
{
// the user wants to add
}
else if ($this->input->post('update') == 'y')
{
// user wants to update
}
else
{
// user wants to delete
}
// rest of code goes here
on each if structure, you can take the appropriate actions depending on which button the user pressed
I have to create a form with a submit bottom following a link
<form action="http://domain/**(((MY TEXT INPUT VALUE)))**.htm">
<input type="text" name="verb">
<input type="submit" value="Conjugate">
</form>
something like this.
please note that every link should be different.
I also want that the new page be opened in a new tab/window
could you please help me, and also make changes to the form code if there is sth under newer standards. Thank you!
You need to use javascript to get the TEXTBOX value and then place it into the form action.
You can create the submit button with an onclickevent.
Or you can use jQuery
$('#btnSubmit').click(function(){
var sTextValue = $("#MyText").val();
$('#MyForm').attr('action', 'htttp://domain/' + sTextValue + '.htm');
$('#MyForm').submit();
});
And the HTML
<form id="MyForm" action="">
<input id="MyText" type="text" name="verb">
<input id="btnSubmit" type="button" value="Conjugate">
</form>
There are many ways to accomplish this. That's just one of them.
<form action="http://domain/**(((MY TEXT INPUT VALUE)))**.htm" id="btnForm">
<input type="text" name="verb" onchange='javascript:document.getElementById("btnForm").action = "http://domain/"+ this.value +".htm"'>
<input type="submit" value="Conjugate" >
</form
This would update as soon you type the text. It wouldn't require jquery. it makes use of onchange event handler of input type text
<form action="http://domain/**(((MY TEXT INPUT VALUE)))**.htm" id="btnForm">
<input type="text" name="verb" onchange='updateFormAction(this.value)'>
<input type="submit" value="Conjugate" >
</form>
<script type="text/javascript">
function updateFormAction(value){
var btnForm = document.getElementById("btnForm");
btnForm.action = "http://domain/"+ value +".htm";
}
</script>
This is more explanatory form. Its based on onchange event handler for text types.
I'm currently creating a form that is very similar to the following code.
<form name="test" action="/go/test" method="post">
<input type=hidden name="hotspot_url" value="http://www.test.com/">
<input name="cky" value="<%write(cky);%>" type="hidden">
<input name="accept" value="Accept" type="hidden">
<input name="saccept" size="20" value="I Accept" onClick="hotspot.accept.value='Accept'" type="submit">
<input name="sdisconnect" size="20" value="I Decline" onClick="hotspot.accept.value='Decline'" type="submit">
</form>
However, the new form has a text input field. What I want to achieve is that the value entered in that text field is placed, upon send, after the test.com value (location marked with xxx)
<input type=hidden name="hotspot_url" value="http://www.test.com/xxx">
I've looked around - but i can't seem to find a solution.
What would be the best way to get this done?
You can use a buttons onclick event, which is not of type submit. When onclick occurs, you can first change the value of hidden field and then submit the form.
Or if you use JQuery, you can use the following jQuery code to do something before the form is submitted:
$(function() {
$('#form').submit(function() {
// DO STUFF
return true; // return false to cancel form action
});
});
You can give both inputs an id, and do something like this:
give the form an "onsumbit= doThis()"
function doThis(){
var hiddeninput= $('#hiddeninput').val();
var input = $('#input').val();
$('#hiddeninput').val(hiddeninput+input);
return true;
}
this is very simple nothing fancy.
I have a external js file that has the following function in it. It is supped to be called by the forms onsubmit but it doesn't appear to be happening. The form is just submitted without validation. At one point this was working but now it is not. Where am I going wrong? Any help is appreciated.
function validateDelete(form)
{
alert("Validation Started!");
var photoName=form.deleteName;
if (photoName === "")
{
alert("Photo Name Required");
return false;
}
}
<script src="galleryScripts/validation.js" type="text/javascript" ></script>
<form action="galleryScripts/deletePhoto.php?submit=true" name="deleteForm" onsubmit="return validateDelete(this);" id="deleteForm" method="post">
<label>
File Name: <input name="deleteName" type="text" id="deleteName">
</label>
<label>
<input type="submit" name="deleteButton" id="deleteButton" value="Delete" />
</label>
</form>
Make sure that your js is included.
For example under mozilla press CTRL+U and click on a link to your validation.js file.
Also you can just paste in tag in your tag it should work.
