I have the following html code:
Here is a simple way to do this :
Html :

checkbox1
checkbox2
checkbox3
jquery :
$(document).ready(function(){
$("#selectall").click(function(){
if(this.checked){
$('.checkboxall').each(function(){
$(".checkboxall").prop('checked', true);
})
}else{
$('.checkboxall').each(function(){
$(".checkboxall").prop('checked', false);
})
}
});
});
