首先头部引用jquery库

然后

把以下JS单独存为一个js文件,引用进去

$(document).ready(function() {

	// Generate the clips. In this case I'm using 5 (or 25 pieces)
	(genClips = function() {

		// For easy use
		$t = $('.clipped-box');

		// Like I said, we're using 5!
		var amount = 5;

		// Get the width of each clipped rectangle.
		var width = $t.width() / amount;
		var height = $t.height() / amount;

		// The total is the square of the amount
		var totalSquares = Math.pow(amount, 2);

		// The HTML of the content
		var html = $t.find('.content').html();

		var y = 0;

		for(var z = 0; z <= (amount*width); z = z+width) { 

			$('<div style="clip: rect('+y+'px, '+(z+width)+'px, '+(y+height)+'px, '+z+'px)">'+html+'</div>').appendTo($t);

			if(z === (amount*width)-width) {

				y = y + height;
				z = -width;

			}

			if(y === (amount*height)) {
				z = 9999999;
			}

		}

	})();

	// A quick random function for selecting random numbers
	function rand(min, max) {

		return Math.floor(Math.random() * (max - min + 1)) + min;

	}

	// A variable check for when the animation is mostly over
	var first = false,
		clicked = false;

	// On click
	$('.clipped-box div').on('click', function() {

		if(clicked === false) {

			clicked = true;

			$('.clipped-box .content').css({'display' : 'none'});	

			// Apply to each clipped-box div.
			$('.clipped-box div:not(.content)').each(function() {

				// So the speed is a random speed between 90m/s and 120m/s. I know that seems like a lot
				// But otherwise it seems too slow. That's due to how I handled the timeout.
				var v = rand(120, 90),
					angle = rand(80, 89), // The angle (the angle of projection) is a random number between 80 and 89 degrees.
					theta = (angle * Math.PI) / 180, // Theta is the angle in radians
					g = -9.8; // And gravity is -9.8. If you live on another planet feel free to change

				// $(this) as self
				var self = $(this);

				// time is initially zero, also set some random variables. It's higher than the total time for the projectile motion
				// because we want the squares to go off screen. 
				var t = 0,
					z, r, nx, ny,
					totalt =  15;

				// The direction can either be left (1), right (-1) or center (0). This is the horizontal direction.
				var negate = [1, -1, 0],
					direction = negate[ Math.floor(Math.random() * negate.length) ];

				// Some random numbers for altering the shapes position
				var randDeg = rand(-5, 10), 
					randScale = rand(0.9, 1.1),
					randDeg2 = rand(30, 5);

				// Because box shadows are a bit laggy (by a bit I mean 'box shadows will not work on individual clipped divs at all') 
				// we're altering the background colour slightly manually, in order to give the divs differentiation when they are
				// hovering around in the air.
				var color = $(this).css('backgroundColor').split('rgb(')[1].split(')')[0].split(', '),
					colorR = rand(-20, 20),  // You might want to alter these manually if you change the color
					colorGB = rand(-20, 20),  // To get the right consistency.
					newColor = 'rgb('+(parseFloat(color[0])+colorR)+', '+(parseFloat(color[1])+colorGB)+', '+(parseFloat(color[2])+colorGB)+')';

				// And apply those
				$(this).css({
					'transform' : 'scale('+randScale+') skew('+randDeg+'deg) rotateZ('+randDeg2+'deg)', 
					'background' : newColor
				});

				// Set an interval
				z = setInterval(function() { 	

					// Horizontal speed is constant (no wind resistance on the internet)
					var ux = ( Math.cos(theta) * v ) * direction;

					// Vertical speed decreases as time increases before reaching 0 at its peak
					var uy = ( Math.sin(theta) * v ) - ( (-g) * t);

					// The horizontal position
					nx = (ux * t);

					// s = ut + 0.5at^2
					ny = (uy * t) + (0.5 * (g) * Math.pow(t, 2));

					// Apply the positions	
					$(self).css({'bottom' : (ny)+'px', 'left' : (nx)+'px'});

					// Increase the time by 0.10
					t = t + 0.10;

					// If the time is greater than the total time clear the interval
					if(t > totalt) {

						clicked = false;
						first = true;

						$('.clipped-box').css({'top' : '-1000px', 'transition' : 'none'});
						$(self).css({'left' : '0', 'bottom' : '0', 'opacity' : '1', 'transition' : 'none', 'transform' : 'none'});

						// Finally clear the interval
						clearInterval(z);

					}

				}, 10); // Run this interval every 10ms. Changing this will change the pace of the animation

			});

		}

	});

	r = setInterval(function() {

		// This is a bit rough but it does the job
		if(first === true) {

			// I've just put this in so the deleted box will come down again after its been clicked.
			// That way you can keep pressing delete.

			$('.clipped-box').css({'top' : '0', 'transition' : ''});
			$('.clipped-box div').css({'opacity' : '1', 'transition' : '', 'background-color' : ''});

			$('.content').css({'display' : 'block'});

			first = false;

		}

	}, 300);
});

然后把以下DIV嵌入进去就可以了

<div class="container">
<div class="clipped-box">
    <div class="content">
        <h1>CLICK TO DELETE ME</h1>
        <p>I'll explode into pieces!</p>
    </div>
</div>
 </div>
