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.
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;
}

The above code is no longer up to date.
Several errors have been corrected in the past two days.
This article comes from Blog Park jelle blog http://www.cnblogs.com/idche/

实现方法:1、用“$("img").delay(毫秒数).fadeOut()”语句,delay()设置延迟秒数;2、用“setTimeout(function(){ $("img").hide(); },毫秒值);”语句,通过定时器来延迟。

修改方法:1、用css()设置新样式,语法“$(元素).css("min-height","新值")”;2、用attr(),通过设置style属性来添加新样式,语法“$(元素).attr("style","min-height:新值")”。

区别:1、axios是一个异步请求框架,用于封装底层的XMLHttpRequest,而jquery是一个JavaScript库,只是顺便封装了dom操作;2、axios是基于承诺对象的,可以用承诺对象中的方法,而jquery不基于承诺对象。

增加元素的方法:1、用append(),语法“$("body").append(新元素)”,可向body内部的末尾处增加元素;2、用prepend(),语法“$("body").prepend(新元素)”,可向body内部的开始处增加元素。

在jquery中,apply()方法用于改变this指向,使用另一个对象替换当前对象,是应用某一对象的一个方法,语法为“apply(thisobj,[argarray])”;参数argarray表示的是以数组的形式进行传递。

删除方法:1、用empty(),语法“$("div").empty();”,可删除所有子节点和内容;2、用children()和remove(),语法“$("div").children().remove();”,只删除子元素,不删除内容。

去掉方法:1、用“$(selector).removeAttr("readonly")”语句删除readonly属性;2、用“$(selector).attr("readonly",false)”将readonly属性的值设置为false。

on()方法有4个参数:1、第一个参数不可省略,规定要从被选元素添加的一个或多个事件或命名空间;2、第二个参数可省略,规定元素的事件处理程序;3、第三个参数可省略,规定传递到函数的额外数据;4、第四个参数可省略,规定当事件发生时运行的函数。
