I am building a form in Shopify. On click of a button, I call a JavaScript function that takes some of the fields, sets them in hidden variables and then submits the form...here are some snippets.
<input type="button" name="next" onclick="javascript:validate(); return false;" class="btn" value="Next">
function validate(){
var xv = $( "#x" ).val();
var hd = $("<input>").attr("type", "hidden").attr("name", "hx[aa]").attr("id", "hx[aa]").val("xv");
$('#myForm').append(hd);
$("#myForm").submit();
}
The form method is set to post but when the submit happens, i can see the hx[aa] in the query string.
?hx[aa]=12345
I have a feeling that this has nothing to do with Shopify but something else that I am missing on. Any help is greatly appreciated. Thanks.
Make sure you form has method attribute with value that is equal to post
<form method="post" id="myForm">
<input type="button" name="next" onclick="javascript:validate(); return false;" class="btn" value="Next">
</form>
I've got on my index.php form with POST method.
Action is form.php, so it's different file, but I'm using iframe to show my result, still being at index.php.
One more thing that I need, is to show one of my text inputs, still on index.php, when I do click submit button. I've tried to use onClick action:
<script type="text/javascript">
function showamount()
{
var price = document.getElementById('amount').value;
document.getElementById("some_p").innerHTML = price;
}
</script>
<input type="text" id="amount" />
<input type="submit" value="Podlicz" onclick="showamount()" />
<p id="some_p"></p>
It does not work there, when submit button is dedicated to form, with an action (I suppose, because it works without form, when is pure like above)
What is wrong? Thanks!
Try this <form id="form" onSubmit="return showamount();" action="form.php" target="_blank">
That will open a new window to run the form.php and will also update current page with inputed value.
javascript
<script>
function showamount()
{
var price = document.getElementById('amount').value;
document.getElementById("some_p").innerHTML = price;
return true;
}
</script>
html
<form id="form" onSubmit="return showamount();" action="form.php" target="_blank">
<input type="text" id="amount" />
<input type="submit" value="Podlicz" onclick="showamount()" />
</form>
<p id="some_p"></p>
I currently have a button in HTML with the following code:
<form id="tfnewsearch" method="get" >
<input type="text" id="search_query" name="q" size="21" maxlength="120"><input type="button" id="search_button" name="search" value = "Search"onclick="doSearch(this.form.q)">
</form>
The function 'doSearch()' works only if I click the submit button. What changes do I have to do if it has to work even if I just press the Enter key?
<form id="tfnewsearch" method="get" onsubmit="doSearch()" >
Simply change the onclick to an onsubmit and attach it to your form!
The proper way it to move it to simple JS script
<script type="text/javascript">
var form = document.querySelector('#tfnewsearch'),
query = form.querySelector('[name="q"]');
form.addEventListener('submit', function(){
doSearch(query.value);
});
</script>
I have a form in which there is one text field is provided with a submit button.On clicking submit button,it redirects to second php page from first php page.
index.php
<form action="submit.php" method="get">
<input type="text" name="search" id="search" />
<input type="submit" value="submit" onclick="convert()" />
</form
<script type="text/javascript">
function convert()
{
alert("hi");
var str ;
str = document.getElementById("search").value;
document.writeln(str.toLowerCase());
}
</script>
On submitting the form,i want the url to become like submit.php?search=text
I want this text to be in lower case,although if text entered is uppercase.
Please guide me how to make this text lower case,I am using the above script for converting it to lower case.But its not converting the text in lower case in URL.
Please guide me on this..
There was a few errors, you were missing the right angle bracket on </form> and you were trying to write the value rather than setting the field value, try this...
<form action="submit.php" method="get">
<input type="text" name="search" id="search" />
<input type="submit" value="submit" onclick="convert();" />
</form>
<script type="text/javascript">
function convert() {
alert("hi");
var str;
var srch=document.getElementById("search");
str = srch.value;
srch.value=str.toLowerCase();
}
</script>
You can do this only using javascript with a few extra stuff:
1) Give your <form> an id
<form action="submit.php" method="get" id="form1">
2) Make your <input> type as button. The reason for this is because we want to make sure the convert() function is executed first, and after that we will submit the form.
<input type="button" value="submit" onclick="convert()" />
3) Finally javascript to:
function convert()
{
alert("hi");
var str ;
str = document.getElementById("search");
str.value = (str.value.toLowerCase());
//get the form id and submit it
var form = document.getElementById("form1");
form.submit();
}
Fiddle
You are use form element so you can get any elements inside form element access by name, Here Our form name is form1 and inside this form inputbox name="search" and access this value by this way, document.form1.search.value.toLowerCase();
Check this Demo jsFiddle
JavaScript
function convert() {
alert("hi");
var str = document.form1.search.value.toLowerCase();
document.writeln(str);
//console.log(str);
}
HTML
<form name="form1" method="get">
<input type="text" name="search" id="search" />
<input type="submit" value="submit" onclick="convert();" />
</form >
try like this:
alert("hi");
document.getElementById("search").value = document.getElementById("search").value.toLowerCase();
return true;

I have one HTML <form>.
The form has only one action="" attribute.
However I wish to have two different target="" attributes, depending on which button you click to submit the form. This is probably some fancy JavaScript code, but I haven't an idea where to begin.
How could I create two buttons, each submitting the same form, but each button gives the form a different target?
I do this on the server-side.
That is, the form always submits to the same target, but I've got a server-side script who is responsible for redirecting to the appropriate location depending on what button was pressed.
If you have multiple buttons, such as
<form action="mypage" method="get">
<input type="submit" name="retry" value="Retry" />
<input type="submit" name="abort" value="Abort" />
</form>
Note: I used GET, but it works for POST too
Then you can easily determine which button was pressed - if the variable retry exists and has a value then retry was pressed, and if the variable abort exists and has a value then abort was pressed. This knowledge can then be used to redirect to the appropriate place.
This method needs no Javascript.
Note: This question and answer was from so many years ago when "wanting to avoid relying on Javascript" was more of a thing than it is today. Today I would not consider writing extra server-side functionality for something like this. Indeed, I think that in most instances where I would need to submit form data to more than one target, I'd probably be doing something that justified doing a lot of the logic client-side in Javascript and using XMLHttpRequest (or indeed, the Fetch API) instead.
It is more appropriate to approach this problem with the mentality that a form will have a default action tied to one submit button, and then an alternative action bound to a plain button. The difference here is that whichever one goes under the submit will be the one used when a user submits the form by pressing enter, while the other one will only be fired when a user explicitly clicks on the button.
Anyhow, with that in mind, this should do it:
<form id='myform' action='jquery.php' method='GET'>
<input type='submit' id='btn1' value='Normal Submit'>
<input type='button' id='btn2' value='New Window'>
</form>
With this javascript:
var form = document.getElementById('myform');
form.onsubmit = function() {
form.target = '_self';
};
document.getElementById('btn2').onclick = function() {
form.target = '_blank';
form.submit();
}
Approaches that bind code to the submit button's click event will not work on IE.
In case you are up to HTML5, you can just use the attribute formaction. This allows you to have a different form action for each button.
<!DOCTYPE html>
<html>
<body>
<form>
<input type="submit" formaction="firsttarget.php" value="Submit to first" />
<input type="submit" formaction="secondtarget.php" value="Submit to second" />
</form>
</body>
</html>
This works for me:
<input type='submit' name='self' value='This window' onclick='this.form.target="_self";' />
<input type='submit' name='blank' value='New window' onclick='this.form.target="_blank";' />
In this example, taken from
http://www.webdeveloper.com/forum/showthread.php?t=75170
You can see the way to change the target on the button OnClick event.
function subm(f,newtarget)
{
document.myform.target = newtarget ;
f.submit();
}
<FORM name="myform" method="post" action="" target="" >
<INPUT type="button" name="Submit" value="Submit" onclick="subm(this.form,'_self');">
<INPUT type="button" name="Submit" value="Submit" onclick="subm(this.form,'_blank');">
Simple and easy to understand, this will send the name of the button that has been clicked, then will branch off to do whatever you want. This can reduce the need for two targets. Less pages...!
<form action="twosubmits.php" medthod ="post">
<input type = "text" name="text1">
<input type="submit" name="scheduled" value="Schedule Emails">
<input type="submit" name="single" value="Email Now">
</form>
twosubmits.php
<?php
if (empty($_POST['scheduled'])) {
// do whatever or collect values needed
die("You pressed single");
}
if (empty($_POST['single'])) {
// do whatever or collect values needed
die("you pressed scheduled");
}
?>
Example:
<input
type="submit"
onclick="this.form.action='new_target.php?do=alternative_submit'"
value="Alternative Save"
/>
Voila.
Very "fancy", three word JavaScript!
Here's a quick example script that displays a form that changes the target type:
<script type="text/javascript">
function myTarget(form) {
for (i = 0; i < form.target_type.length; i++) {
if (form.target_type[i].checked)
val = form.target_type[i].value;
}
form.target = val;
return true;
}
</script>
<form action="" onSubmit="return myTarget(this);">
<input type="radio" name="target_type" value="_self" checked /> Self <br/>
<input type="radio" name="target_type" value="_blank" /> Blank <br/>
<input type="submit">
</form>
HTML:
<form method="get">
<input type="text" name="id" value="123"/>
<input type="submit" name="action" value="add"/>
<input type="submit" name="action" value="delete"/>
</form>
JS:
$('form').submit(function(ev){
ev.preventDefault();
console.log('clicked',ev.originalEvent,ev.originalEvent.explicitOriginalTarget)
})
http://jsfiddle.net/arzo/unhc3/
<form id='myForm'>
<input type="button" name="first_btn" id="first_btn">
<input type="button" name="second_btn" id="second_btn">
</form>
<script>
$('#first_btn').click(function(){
var form = document.getElementById("myForm")
form.action = "https://foo.com";
form.submit();
});
$('#second_btn').click(function(){
var form = document.getElementById("myForm")
form.action = "http://bar.com";
form.submit();
});
</script>
It is do-able on the server side.
<button type="submit" name="signin" value="email_signin" action="/signin">Sign In</button>
<button type="submit" name="signin" value="facebook_signin" action="/facebook_login">Facebook</button>
and in my node server side script
app.post('/', function(req, res) {
if(req.body.signin == "email_signin"){
function(email_login) {...}
}
if(req.body.signin == "fb_signin"){
function(fb_login) {...}
}
});
Have both buttons submit to the current page and then add this code at the top:
<?php
if(isset($_GET['firstButtonName'])
header("Location: first-target.php?var1={$_GET['var1']}&var2={$_GET['var2']}");
if(isset($_GET['secondButtonName'])
header("Location: second-target.php?var1={$_GET['var1']}&var2={$_GET['var2']}");
?>
It could also be done using $_SESSION if you don't want them to see the variables.
Alternate Solution. Don't get messed up with onclick,buttons,server side and all.Just create a new form with different action like this.
<form method=post name=main onsubmit="return validate()" action="scale_test.html">
<input type=checkbox value="AC Hi-Side Pressure">AC Hi-Side Pressure<br>
<input type=checkbox value="Engine_Speed">Engine Speed<br>
<input type=submit value="Linear Scale" />
</form>
<form method=post name=main1 onsubmit="return v()" action=scale_log.html>
<input type=submit name=log id=log value="Log Scale">
</form>
Now in Javascript you can get all the elements of main form in v() with the help of getElementsByTagName(). To know whether the checkbox is checked or not
function v(){
var check = document.getElementsByTagName("input");
for (var i=0; i < check.length; i++) {
if (check[i].type == 'checkbox') {
if (check[i].checked == true) {
x[i]=check[i].value
}
}
}
console.log(x);
}
This might help someone:
Use the formtarget attribute
<html>
<body>
<form>
<!--submit on a new window-->
<input type="submit" formatarget="_blank" value="Submit to first" />
<!--submit on the same window-->
<input type="submit" formaction="_self" value="Submit to second" />
</form>
</body>
</html>
On each of your buttons you could have the following;
<input type="button" name="newWin" onclick="frmSubmitSameWin();">
<input type="button" name="SameWin" onclick="frmSubmitNewWin();">
Then have a few small js functions;
<script type="text/javascript">
function frmSubmitSameWin() {
form.target = '';
form.submit();
}
function frmSubmitNewWin() {
form.target = '_blank';
form.submit();
}
</script>
That should do the trick.
e.submitEvent.originalEvent.submitter.value
if you use event of form
