Click a specific submit button with JQuery

问题:

I am clicking a submit button using this:

$('input[type=submit]').click(); 

The problem is that I have more that 1 submit button on my page so I need to target a specific submit button.

How could I do that?

回答1:

If you know the number of submit inputs and which one (in order) you want to trigger a click on then you can use nth-child() syntax to target it. Or add an ID or a class to each one that separates them from the other.

Selecting the elements by their index:

$('input[type="submit"]:nth-child(1)').trigger('click');//selects the first one
$('input[type="submit"]:nth-child(2)').trigger('click');//selects the second one
$('input[type="submit"]:nth-child(100)').trigger('click');//selects the 100th one

There are actually several ways to do this including using .eq(): http://api.jquery.com/eq

Selecting the elements by their id:

<input type="submit" id="submit_1" />
<input type="submit" id="submit_2" />
<input type="submit" id="submit_100" />

<script>
$('#submit_100').trigger('click');
</script>

Note that .click() is short for .trigger('click').

If you add a marker, like a specific id or class to your input, you can make your selector more specific. For example, if you give the button you want the ID of form-btn like this:

<input type="submit" id="form-btn" />

You can select it like this:

$('input[type=submit]#form-btn').click();

Or just:

$('#form-btn').click();

Add ids to each button and select the id with jQuery.

Or, if the forms have ids, then just target the form and submit it like so:

$("#form-id").submit();

Way late to the party, but if your submit buttons have names:

$("input[name='submitbuttonname']").click();

One other suggestion!

I had a form with multiple submits, that also had varying value attributes, so I couldn't simply submit the form after I performed my built in confirmation.

Instead, I added a few hidden buttons that I forced a click on after I got a Yes back from my confirmation.

Here are the buttons:

<button id="email" name="email" type="submit" class="submit radius confirmation" value="all"><?php echo $this->__('Email Receipts to Selected'); ?></button>
<button id="email-french" name="email-french" type="submit" class="submit radius confirmation" value="all"><?php echo $this->__('Email French Receipts to Selected'); ?></button>
<button id="helper-email" name="email" type="submit" class="submit hide" value="all"></button>
<button id="helper-email-french" name="email-french" type="submit" class="submit hide" value="all"></button>

And here's the jQuery:

<script type="text/javascript">
jQuery(function ($) {
    $('[id^=email]').on('click', function (e) {
        e.preventDefault();

        var button = $(this);

        notify.confirm(<?php echo json_encode($this->__('Are you sure?')); ?>, function (ans) {
            if (ans) {
                $('#helper-' + button.attr('id')).click();
            }
        });
    });
});
</script>
