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

The Question :

706 people think this question is useful

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?

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!
  console.log('Thing was saved to the database.');
} else {
  // Do nothing!
  console.log('Thing was not saved to the database.');
}

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

Use window.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>

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 &amp;&amp; !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>

You have to create custome confirmBox,it is not possible to change the buttons in the dialog displayed by the confirm function.

Jquery confirmBox


see this example: https://jsfiddle.net/kevalbhatt18/6uauqLn6/

<div id="confirmBox">
    <div class="message"></div>
    <span class="yes">Yes</span>
    <span class="no">No</span>
</div>

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

Call it by your code:

doConfirm("Are you sure?", function yes()
{
    form.submit();
}, function no()
{
    // do nothing
});

** Pure JavaScript confirmBox**


Example: http://jsfiddle.net/kevalbhatt18/qwkzw3rg/127/


<div id="id_confrmdiv">confirmation
    <button id="id_truebtn">Yes</button>
    <button id="id_falsebtn">No</button>
</div>

<button onclick="doSomething()">submit</button>

Script:

<script>

function doSomething(){
document.getElementById('id_confrmdiv').style.display="block"; //this is the replace of this line


document.getElementById('id_truebtn').onclick = function(){
   //do your delete operation
    alert('true');
};

document.getElementById('id_falsebtn').onclick = function(){
     alert('false');
   return false;
};
}
</script>

CSS:

body { font-family: sans-serif; }
#id_confrmdiv
{
    display: none;
    background-color: #eee;
    border-radius: 5px;
    border: 1px solid #aaa;
    position: fixed;
    width: 300px;
    left: 50%;
    margin-left: -150px;
    padding: 6px 8px 8px;
    box-sizing: border-box;
    text-align: center;
}
#id_confrmdiv button {
    background-color: #ccc;
    display: inline-block;
    border-radius: 3px;
    border: 1px solid #aaa;
    padding: 2px;
    text-align: center;
    width: 80px;
    cursor: pointer;
}
#id_confrmdiv .button:hover
{
    background-color: #ddd;
}
#confirmBox .message
{
    text-align: left;
    margin-bottom: 8px;
}

You can intercept the onSubmit event ising JS. Then call a confirmation alert and then grab the result.

Another way to do this:

$("input[name='savedata']").click(function(e){
       var r = confirm("Are you sure you want to save now?");

       //cancel clicked : stop button default action 
       if (r === false) {
           return false;
        }

        //action continues, saves in database, no need for more code


   });

This a full responsive solution using vanilla javascript :

// Call function when show dialog btn is clicked
document.getElementById("btn-show-dialog").onclick = function(){show_dialog()};
var overlayme = document.getElementById("dialog-container");

function show_dialog() {
 /* A function to show the dialog window */
    overlayme.style.display = "block";
}

// If confirm btn is clicked , the function confim() is executed
document.getElementById("confirm").onclick = function(){confirm()};
function confirm() {
 /* code executed if confirm is clicked */   
    overlayme.style.display = "none";
}

// If cancel btn is clicked , the function cancel() is executed
document.getElementById("cancel").onclick = function(){cancel()};
function cancel() {
 /* code executed if cancel is clicked */  
    overlayme.style.display = "none";
}

xdialog provides a simple API xdialog.confirm(). Code snippet is following. More demos can be found here

document.getElementById('test').addEventListener('click', test);

function test() {
  xdialog.confirm('Are you sure?', function() {
    // do work here if ok/yes selected...
    console.info('Done!');
  }, {
    style: 'width:420px;font-size:0.8rem;',
    buttons: {
      ok: 'yes text',
      cancel: 'no text'
    },
    oncancel: function() {
      console.warn('Cancelled!');
    }
  });
}

The easiest way to ask before action on click is following

<a onclick="return askyesno('Delete this record?');" href="example.php?act=del&amp;del_cs_id=<?php echo $oid; ?>">
<button class="btn btn-md btn-danger">Delete </button>
</a>

Made super simple, tiny vanilla js confirm dialog with Yes and No buttons.
It’s a pity we can’t customize the native one.
