The example of this article is about JS simple realization of click-and-Move method. Share to everyone for your reference. The specific analysis is as follows:

This can be achieved click to the right, the box to the right, click Left, the box to the left to move the effect

can use setinterval to achieve too long time, div move how long distance to achieve the motion effect.

Point one: If the left distance of the element is less than the target distance, it is a forward move, otherwise it is a negative move

if (Run.offsetleft <target) {
speed = 2;
} else{
speed =-2;
}

Point two: If the left distance of the element equals the target distance, stop the timer, otherwise the left distance of the element equals the current left distance plus the speed value.

if (Run.offsetleft ==target) {
clearinterval (timer);
}
else{
run.style.left = run.offsetleft +speed + "px";
}
