An image transfer effect implemented by javascript_image special effects

May 16, 2016 pm 07:12 PM

At the request of netizens, I modified a picture transfer effect. It is a relatively beautiful effect, but it is a little troublesome to add picture effects. Today, JS has been changed at the request of netizens. Make it easier for everyone to add and delete pictures. Here we mainly explain the following points in detail.
var firstnum = 1;
var secnum = 2;
var tounum=1;
These three variables are used to pass in the image ID variable. And save the current picture ID for easy operation! I believe everyone can easily modify it to the effect they want!
The code is as follows:


[Ctrl A select all Note: If you need to introduce external Js, you need to refresh to execute
]
<script> var ticked=0; var okayToGo = true; var currentCreature = 1; var forwardBackward = 1; var firstnum = 1; var secnum = 2; var tounum=1; function moveItem(firstnum,secnum){ if(okayToGo&& firstnum != secnum){ tounum=firstnum; document.getElementById("y"+firstnum).style.zIndex = 50+10*forwardBackward; document.getElementById("y"+secnum).style.zIndex = 50+20*forwardBackward; startTheMove =window.setInterval(function(){rightOrLeft(firstnum,secnum)},20); } } function rightOrLeft(firstnum,secnum) { if (ticked == 1020) { window.clearInterval(startTheMove); ticked = 0; forwardBackward = 1; okayToGo = true; } else { okayToGo = false; thisAngle = (Math.PI/2)*(ticked/1000); document.getElementById("y"+firstnum).style.left = " "+(735-Math.sin(thisAngle)*700)+"px"; document.getElementById("y"+firstnum).style.top = " "+(105-(forwardBackward*Math.cos(thisAngle)*55))+"px"; document.getElementById("y"+secnum).style.left = " "+(735-Math.sin(thisAngle+Math.PI/2)*700)+"px"; document.getElementById("y"+secnum).style.top = " "+(105-(forwardBackward*Math.cos(thisAngle+Math.PI/2)*55))+"px"; ticked += 20; } } </script>

What is 'this' in JavaScript? What is 'this' in JavaScript? Mar 04, 2025 am 01:15 AM

Core points This in JavaScript usually refers to an object that "owns" the method, but it depends on how the function is called. When there is no current object, this refers to the global object. In a web browser, it is represented by window. When calling a function, this maintains the global object; but when calling an object constructor or any of its methods, this refers to an instance of the object. You can change the context of this using methods such as call(), apply(), and bind(). These methods call the function using the given this value and parameters. JavaScript is an excellent programming language. A few years ago, this sentence was
