Animate custom animation that simulates jquery implemented using js (2.5K)_jquery

Later I found out it was pretty good. Might as well keep writing.
This version is basically the same as jquery’s animate.
I mean the effect is basically the same. (The efficiency has not been tested yet.);
If there are professional testers, please help me test it.
1: Function description
Compatible with mainstream browsers.
1: Support callback function;
2: Support cascade animation call;
3: Support delay animation queue delay;
4: Support stop animation;
5: Support opacity transparency change ;
6: Support = -= *= /= operation;
7: Support unit operation (px, %);
2: Instructions for use
jelle(A).animate(B, C , D);
A: The ID of the dom element that needs to be animated;
B: The main parameters of the animation are passed {key, val, key2, val2}; such as {width:'100px',height:' =100px ',opacity:0.5},
opacity--transparency change supports = -= *= /= operations.
C: animation execution time, in milliseconds; [optional default 500 milliseconds];
D: callback function; [optional]
3: method description
1: animate() method
jelle('cc').animate({width:'100px'},300,function(){alert('Complete')});//The width of cc changes to 100px in 300 milliseconds animation The end pops up 'Complete'
2:stop() method
jelle('cc').stop();//Stop the animation being played on the cc object.
3: delay() method
jelle('cc').delay(1000).animate({width:'100px'}); //Changes in the width of cc will be executed with a delay of 1 second.
I will keep improving him.

Copy code The code is as follows:

var jelle = function(id){
var $ = function(id){ return document.getElementById(id); },
elem = $(id),//Object
f = 0, _this = {}, lazy = 10, lazyque = 10,//f animation counter lazy animation delay lazyque queue delay
//You can change the operator to make your animation different
tween = function(t, b, c, d){ return - c * (t /= d) * (t - 2) b},
// adv is used for = -= *= /= operation
adv = function(val, b){
var va, re= /^([ -\*/]=)([-]?[d.] )/ ;
if (re.test( val)){
var reg = val.match(re);
reg[2] = parseFloat(reg[2]);
switch ( reg[1] ){
case ' = ':
va = reg[2];
break;
case '-=':
va = -reg[2];
break;
case '*=' :
va = b*reg[2] - b;
break;
case '/=':
va = b/reg[2] - b;
break;
}
return va;
}
return parseFloat(val) - b;
}
// elem.animate reads the animation queue used on the current dom element
elem .animate = elem.animate || [];
//stop function to be used
jelle[id]= {};
jelle[id]['stop'] = true;
//alert(jelle[id]['stop'])
// The unified queue entry is used to conveniently set the delay, and stop
_this.entrance = function(fn, ags, lazytime){

The above code is no longer up to date.

Several errors have been corrected in the past two days.
