How to create a dialog with “yes” and “no” options?

How to create a dialog with “yes” and “no” options?

I am going to make a button to take an action and save the data into a database.
Once the user clicks on the button, I want a JavaScript alert to offer “yes” and “cancel” options. If the user selects “yes”, the data will be inserted into the database, otherwise no action will be taken.
How do I display such a dialog?

Solutions/Answers:

Solution 1:

You’re probably looking for confirm(), which displays a prompt and returns true or false based on what the user decided:

if (confirm('Are you sure you want to save this thing into the database?')) {
    // Save it!
} else {
    // Do nothing!
}

Solution 2:

var answer = confirm("Save data?")
if (answer) {
    //some code
}
else {
    //some code
}

Use confirm instead of alert. This is the easiest way to achieve that functionality.

How to do this using ‘inline’ JavaScript:

<form action="http://www.google.com/search">
  <input type="text" name="q" />
  <input type="submit" value="Go"
    onclick="return confirm('Are you sure you want to search Google?')"
  />
</form>

Solution 4:

Avoid inline JavaScript – changing the behaviour would mean editing every instance of the code, and it ain’t pretty!

A much cleaner way is to use a data attribute on the element, such as data-confirm="Your message here". My code below supports the following actions, including dynamically-generated elements:

  • a and button clicks
  • form submits
  • option selects

jQuery:

$(document).on('click', ':not(form)[data-confirm]', function(e){
    if(!confirm($(this).data('confirm'))){
        e.stopImmediatePropagation();
        e.preventDefault();
    }
});

$(document).on('submit', 'form[data-confirm]', function(e){
    if(!confirm($(this).data('confirm'))){
        e.stopImmediatePropagation();
        e.preventDefault();
    }
});

$(document).on('input', 'select', function(e){
    var msg = $(this).children('option:selected').data('confirm');
    if(msg != undefined && !confirm(msg)){
        $(this)[0].selectedIndex = 0;
    }
});

HTML:

<!-- hyperlink example -->
<a href="http://www.example.com" data-confirm="Are you sure you want to load this URL?">Anchor</a>

<!-- button example -->
<button type="button" data-confirm="Are you sure you want to click the button?">Button</button>

<!-- form example -->
<form action="http://www.example.com" data-confirm="Are you sure you want to submit the form?">
    <button type="submit">Submit</button>
</form>

<!-- select option example -->
<select>
    <option>Select an option:</option>
    <option data-confirm="Are you want to select this option?">Here</option>
</select>

</div>

function doConfirm(msg, yesFn, noFn)
{
    var confirmBox = $("#confirmBox");
    confirmBox.find(".message").text(msg);
    confirmBox.find(".yes,.no").unbind().click(function()
    {
        confirmBox.hide();
