Use JQ to realize the reverse selection of all and no selection at all - Feng Hao's blog

Ideas ：
First call jq file
When we click Select all, we let them all be true
When clicking none of them, we let them all be false
When you click invert Use echo Loop traversal checked Use ！ Take the opposite ;

html part 
	<input type="checkbox">
	<input type="checkbox">
	<button > Future generations </button>
	<button > Not all </button>
	<button'> Reverse election </button>
js part 
	//  Click Select all 
	$('button:first').click(function(){
		$(':checkbox').prop('checked',true);
	})
	
	//  Click none    eq: Get inverse selection button 
	$('button:eq(1)').click(function(){
		$(':checkbox').prop('checked',false);
	})
	
	//  Click invert 
	$('button:last').click(function(){
		$(':checkbox').each(function(index,item){
			item.checked = !item.checked;
		})
	})
