Button text toggle in jquery

When i click ".pushme" button, it turns its text to "Don't push me". I want to turn the text again to "push me" when button is clicked again. How can i do that?

<html>

<head>
    <script src="http://code.jquery.com/jquery-latest.js"></script>
</head>

<body>
    <button class='pushme'>PUSH ME</button>
    <script>
        $(".pushme").click(function () {
            $(this).text("DON'T PUSH ME");
        });
    </script>
</body>

</html>

Thanks.

You can use text method:

$(function(){
   $(".pushme").click(function () {
      $(this).text(function(i, text){
          return text === "PUSH ME" ? "DON'T PUSH ME" : "PUSH ME";
      })
   });
})

You could also use .toggle() like so:

$(".pushme").toggle(function() {
    $(this).text("DON'T PUSH ME");
}, function() {
    $(this).text("PUSH ME");
});

More info at http://api.jquery.com/toggle-event/.

This way also makes it pretty easy to change the text or add more than just 2 differing states.

Use a custom ID if possible if you would like to apply the action to only that button.

HTML

<button class="pushDontpush">PUSH ME</button>

jQuery

$("#pushDontpush").click(function() { 
    if ($(this).text() == "PUSH ME") { 
        $(this).text("DON'T PUSH ME"); 
    } else { 
        $(this).text("PUSH ME"); 
    }; 
});

Working CodePen: Toggle text in button

With so many great answers, I thought I would toss one more into the mix. This one, unlike the others, would permit you to cycle through any number of messages with ease:

var index = 0,
    messg = [
        "PUSH ME", 
        "DON'T PUSH ME", 
        "I'M SO CONFUSED!"
    ];

$(".pushme").on("click", function() {
    $(this).text(function(index, text){
        index = $.inArray(text, messg);
        return messg[++index % messg.length];
    });
});

Demo: http://jsfiddle.net/DQK4v/2/

Use an if/else statement.. or ternary if you understand it

$(".pushme").click(function () {
    var $el = $(this);
    $el.text($el.text() == "DON'T PUSH ME" ? "PUSH ME": "DON'T PUSH ME");
});

http://jsfiddle.net/dFZyv/

$(".pushme").click(function () {
  var button = $(this);
  button.text(button.text() == "PUSH ME" ? "DON'T PUSH ME" : "PUSH ME")           
});

This ternary operator has an implicit return. If the expression before ? is true it returns "DON'T PUSH ME", else returns "PUSH ME"

This if-else statement:

if (condition) { return A }
else { return B }

has the equivalent ternary expression:

condition ? A : B

I preffer the following way, it can be used by any button.

<button class='pushme' data-default-text="PUSH ME" data-new-text="DON'T PUSH ME">PUSH ME</button>

$(".pushme").click(function () {
    var $element = $(this);
    $element.text(function(i, text) {
        return text == $element.data('default-text') ? $element.data('new-text')
                                                     : $element.data('default-text');
    });
});

demo

If you're setting the button text by using the 'value' attribute you'll need to set

$(this).val()

instead of:

$(this).text()

Also in my situation it worked better to add the JQuery direct to the onclick event of the button:

onclick="$(this).val(function (i, text) { return text == 'PUSH ME' ? 'DON'T PUSH ME' : 'PUSH ME'; });"

You can also use math function to do this

var i = 0;
$('#button').on('click', function() {
    if (i++ % 2 == 0) {
        $(this).val("Push me!");
    } else {
        $(this).val("Don't push me!");
    }
});
