I am trying to set-up a form that has 2 buttons, accept and deny. It doesn't seem to be working. Any thoughts on what I should fix?
<form name="iform" method="post" onsubmit="" onreset="" enctype="multipart/form-data" action="formapprovedeny" class="iform">
Form content here.
<input type="button" onclick="submitForm('html_form_approve.php')" class="submit_button" value="Approved" name="Approved" />
<input type="button" class="submit_button" onclick="submitForm('html_form_deny.php')" value="Denied" name="Denied" />
</form>
Here is the script part.
<script>
function submitForm(action)
{
document.getElementById('formapprovedeny').action = action;
document.getElementById('formapprovedeny').submit();
}
</script>
Your Javscript is trying to submit a form with an id of formapprovedeny but your form does not have an id. Try adding id="formapprovedeny" to your form
It should id="formapprovedeny" not action="formapprovedeny"
<form name="iform" method="post" onsubmit="" onreset="" enctype="multipart/form-data" id="formapprovedeny" class="iform">
You have a problem with your naming.
You try to get the form by it's id, but it is not set. It's name is.
You should use either getElementByName or give your form an id.
The type of button must be 'submit' and the value whatever you want, look this:
<input type="submit" class="submit_button" value="Approved" name="Approved" />
<input type="submit" class="submit_button" value="Denied" name="Denied" />
What do you want to achieve using the 2 buttons? What do you expect?

<script>
function submitForm(action)
{
alert('hello submitForm '+action);
document.getElementById('formapprovedeny').action = action;
document.getElementById('formapprovedeny').submit();
}
</script>
if I use your code (added an alert) this seems to work...whatever it should be doing ;)

I have a form defined:
<form method="post">
<label for="phone_or_uid">Enter a phone number or uid:</label>
<input type="text" name="phone_or_uid" value=""></input>
<input type="submit" name="" value="Submit"></input>
</form>
Currently, when this form is submitted I am able to work with the data and add info to the page based on the value of phone_or_uid. However, what I'd like to do is something where the form redirects to the same page but with the value of phone_or_uid appended to the end. So, if the initial page is https://myhost.com/lookup then submitting the form should bring the user to https://myhost.com/lookup/16175431234 if the value of the phone_or_uid input box is 16175431234.
Essentially, my form should then look something like this:
<form action={some code that puts the value of phone_or_uid here}>
...
</form>
Is this possible? And if so, how could I accomplish this? I don't want to create or redirect to any extra files, if possible.
I would use JavaScript. Listen for the submit event and redirect to a custom url.
this is just a really general example:
<form method="post" onsubmit="submitFunction()">
<label for="phone_or_uid">Enter a phone number or uid:</label>
<input type="text" name="phone_or_uid" id="phone_or_uid" value=""></input>
<input type="submit" name="" value="Submit"></input>
</form>
<script>
submitFunction = (event) => {
event.preventDefault();
const phoneInfo = document.getElementById('phone_or_uid').value;
fetch('http://myhost.com/lookup/' + phoneInfo, {
method: 'post'
})
.then(response => {
window.location.href = "http://myhost.com/lookup/' + phoneInfo";
});
}
</script>
In the example below I've attached a function main to an input field. the function contains instructions to send an alert with a variable message (whatever the user enters into the field).
<form>
<input type="text" onsubmit="main()" />
<input type="submit" />
</form>
<script>
function main (param) {
alert(param)
}
//main();
</script>
It doesn't work, but I believe that's because I've made some noob error that I'm failing to recognize. The result of a functioning version of this code would be the ability to submit "hello world" and produce an alert box stating 'hello world' (without quotes).
But, further than this, I'd like to be able to pass the likes of main("hello world"); or just alert('hello world'); to the input field to produce the same result.
The problem I think I'm running into is that the page is refreshed every time I submit. There are a few questions on here with similar problems where people have suggested the use of onsubmit="main(); return false;", but in fact this does not seem to work.
Looks like you want to eval() the value of the input.
Use with caution, has security impact...
Returning false from a handler stops the regular action so you have no redirect after submitting:
<form onsubmit="main(); return false;">
<input id="eval-input" type="text" />
<input type="submit" />
</form>
<script>
function main () {
eval(document.getElementById('eval-input').value);
}
</script>
Here's how you can detect a form submission:
<form onsubmit="foo()">
<input type="text">
<input type="submit">
</form>
<script>
function foo(){
alert("function called");
}
</script>
I however advise you do this (preference), if you desire to manage the form data through a function:
<form id="myform">
<input type="text">
<input type="submit">
</form>
<script>
document.getElementById("myform").onsubmit=function(event){
alert("function called");
//manage form submission here, such as AJAX and validation
event.preventDefault(); //prevents a normal/double submission
return false; //also prevents normal/double a double submission
};
</script>
EDIT:
use eval() to execute a string as JavaScript.
jQuery way:
You create event listener which will be triggered when user click 'submit'.
<form>
<input type="text" id="text"/>
<input type="submit" />
</form>
<script>
$( "form" ).submit(function( event ) {
event.preventDefault();
alert( $('#text').val() );
});
</script>
To prevent page reloading - you should use event.preventDefault();
Pure JavaScript:
<form>
<input type="text" id="text"/>
<input type="submit" id="submit" />
</form>
<script>
var button = document.getElementById("submit");
var text = document.getElementById("text");
button.addEventListener("click",function(e){
alert(text.value);
},false);
</script>
If I understand what you want to do, you can call the function like this, and writing params[0].value you can access the input value:
function main(params) {
//dosomething;
document.write(params[0].value);
}
<form onsubmit="main(this)">
<input type="text">
<input type="submit">
</form>
Try something like this
onchange="main()"
onmouseenter, onMouseOver, onmouseleave ...
<input type="text" onmouseenter="main()" />
The javascript does not submit the form. On clicking the alert is
called, even checked with the object and it is not null. But the
.submit() method does not submit the form. Stuck here for a long time.
<script type="text/javascript">
$(document).ready(function(){
$("label img").click(function(){
alert("11");
$("#" + $(this).parents("label").attr("for")).click();
});
$("input").change(uploadForm);
});
</script>
<script type="text/javascript">
function uploadForm(){
alert("1");
document.getElementById('UploadFileFormId').submit();
}
</script>
<form id="UploadFileFormId" action="UploadFile" method="post"
enctype="multipart/form-data"
style="width: 40px">
<label for="UploadFileId">
<img src="images/button_up_lo.png"
onmouseover="this.src='images/button_up_hi.png'"
onmouseout="this.src='images/button_up_lo.png'" />
</label>
<span id="uploadSpanId" class="hidden">
<input type="file"
name="UploadFileName"
id="UploadFileId"/>
<button type= "submit" id="uploadButtonId" name= "uploadButton" ></button>
</span>
</form>
Try <input type="submit">
Use $('#uploadButtonId').submit(); since you are using jQuery.
Element ID is case sensitive (uploadButtonId vs UploadFileFormId)
The uploadForm function, which will submit the form, will execute only when the value of the control changes. Is that what you are expecting?
Note that, in this scenario, if you select a file, then select the same file again, no onchange event will fire.
I have small form and links created like this
Contact | Message
<form name="selectform" action="save.php" method="post" target="_blank">
Name: <input type="text" name="test"/>
<input type="submit" value="Submit" name="sub"/>
</form>
When I click "Contact" link, form submit correctly, And If I click "Message" link how to set this form submit to another url
for an example: if i click "Message" link, I want to submit form to edit.php and without using traget="_blank"
You can change the form action using attr() method of jquery,
For example
$('#link1').click(function(){
$('#formId').attr('action', 'page1').submit();
});
$('#link2').click(function(){
$('#formId').attr('action', 'page2').submit();
});
Here you go...
Contact | Message
<form name="selectform" action="save.php" methode="post" target="_blank">
Name: <input type="text" name="test"/>
<input type="submit" value="Submit" name="sub"/>
</form>
Try it like,
Change in HTML
Message
SCRIPT
$('#msgSubmit').on('click',function(e){
e.preventDefault();
$('form[name="selectform"]').attr('action','edit.php')
.removeAttr('target')
.submit();
});
You can use onclick event
<script>
function submitForm(action)
{
document.getElementById('form1').action = action;
document.getElementById('form1').submit();
}
</script>
...
Contact
<a href="#" onclick="submitForm('page2.php')" value="submit 2" >Message</a>
I have done some modification in your code.
please check and let me know.
Contact | Message
<form id="selectform_id" name="selectform" action="" method="post" target="_blank">
Name: <input type="text" name="test"/>
<input type="submit" value="Submit" name="sub"/>
</form>
<script type="text/javascript">
function myaction(actn){
document.getElementById("selectform_id").action = actn;
document.selectform.submit();
}
</script>
I have just done the code for submit the form using JavaScript.
It works in all browsers except in Internet Explorer 6.
I have pasted my HTML form and JavaScript code below.
Can you please find what's the problem with it?
JavaScript:
<script type="text/javascript" language="javascript">
function dodelete(image_id)
{
if (confirm("Are you sure want to delete this image?"))
{
document.getElementById('image_id').value=image_id;
document.del_form.submit();
}
}
</script>
HTML Code:
<form name="del_form" id="del_form" method="post">
<input type="hidden" name="do" id="do" value="delete" />
<input type="hidden" name="image_id" id="image_id" />
</form>
Function Call Code:::
<p class="video">
<a href="javascript:void(0)" onclick="dodelete('<?php echo $row['image_id']?>')">
<img src="<?php echo $cfg->admin_image_path; ?>/delete_icon1.gif" border="0" alt="Delete"/>
</a>
</p>
What is returned by:
document.getElementById('image_id')
It returns one INPUT element of collection of elements?
Try to replace:
document.getElementById('image_id').value=image_id;
with:
document.del_form.image_id.value=image_id;
OnSubmit call for javascript would help.
<form name="del_form" id="del_form" onsubmit="dodelete(value);" >
<input type="hidden" name="do" id="do" value="delete" />
<input type="hidden" name="image_id" id="image_id" />
</form>
There are two things I'd like to try, I'm not sure why or when this doesn't work it seems random, first try to set a timeout for the submit :
document.doSubmit = function() {
document.del_form.submit();
}
setTimeout("document.doSubmit();", 100);
Sometimes, just return something after the click works :
<input type="hidden" name="image_id" id="image_id" onclick="submitFormFunction(); return false;” />
What happens if you replace:
document.del_form.submit();
with:
document.getElementById('del_form').submit()
Try to move method='POST' to the beginning of form element definition.
I mean -- method attribute should be the first attribute of form element.
If I remember well, this fixed some problems with submitting forms on IE6.
I have edited your code a little bit.
<script type="text/javascript" language="javascript">
function dodelete(image_id)
{
if (confirm("Are you sure want to delete this image?"))
{
document.getElementById('image_id').value=image_id;
document.del_form.submit();
}
return false;
}
</script>
and the HTML with some test Image ID and it works in IE6
<form name="del_form" id="del_form" method="post" onSubmit="return(dodelete('2'));">
<input name="do" id="do" value="delete" />
<input name="image_id" id="image_id" />
<input type="submit" value="Submit">
</form>
Let's try again :).
What happen after replacing:
onclick="dodelete('<?php echo $row['image_id']?>')">
with:
onclick="dodelete('<?php echo $row['image_id']?>'); return false;">
What exactly doesn't work with your code? Throw JS error, there is no server request, values in request are empty?
And (maybe the most important question) -- where is action attribute for your del_form form?
replace
<a href="javascript:void(0)"
with
<a href="#"
IE have problem with that for the dom that fires the JS submit.
