jquery check all input:checkbox on button click
You can check previous condition by assign a global variable:
var clicked = false;
$(".checkall").on("click", function() {
$(".checkhour").prop("checked", !clicked);
clicked = !clicked;
this.innerHTML = clicked ? 'Deselect' : 'Select';
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul style="list-style:none">
<li>
<label>
<input class="checkhour" type="checkbox">One</label>
<label>
<input class="checkhour" type="checkbox">Two</label>
<label>
<input class="checkhour" type="checkbox">Three</label>
</li>
<li>
<button type="button" class="checkall">Select</button>
</li>
</ul>var state = false; // desecelted
$('.checkall').click(function () {
$('.checkhour').each(function() {
if(!state) {
this.checked = true;
} else {
this.checked = false;
}
});
//switch
if (state) {
state = false;
} else {
state = true;
}
});
