HTML form with two submit buttons and two "target" attributes

 原文  2009-06-03 02:13:18  6   16    javascript/ html/ forms/ submit

Question

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 : that some browsers are capable of submitting a form without pressing any buttons (by pressing enter). Non-standard as this is, you have to account for it, by having a clear default action and activating that whenever no buttons were pressed. In other words, make sure your form does something sensible (whether that's displaying a helpful error message or assuming a default) when someone hits enter in a different form element instead of clicking a submit button, rather than just breaking.

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');">

Example: 

<input 
  type="submit" 
  onclick="this.form.action='new_target.php?do=alternative_submit'" 
  value="Alternative Save"
/>

Voila. Very "fancy", three word JavaScript!

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");
}
?>

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) 
})

<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) {...}    


        }
    });

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>

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>

e.submitEvent.originalEvent.submitter.value

if you use event of form

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.
