第一次尝试这样封装函数,有不对的地方请大家指正,谢谢!
代码如下:
html部分:
<div class="div1"> <div class="right-div2"> <div class="right-div3"></div> </div> <div class="left-div2"> <div class="left-div3"></div> </div> <div class="div4"><span>0</span>%</div> </div> <div class="div2"> <div class="right-div2"> <div class="right-div3"></div> </div> <div class="left-div2"> <div class="left-div3"></div> </div> <div class="div4"><span>0</span>%</div> </div>
css部分:
*{ margin:0; padding:0;}
.div1, .right-div2, .right-div3, .left-div2, .left-div3 { width:200px; height:200px; border-radius:50%;}
.div1 { background:#ccc; position:relative;}
.right-div2, .right-div3, .left-div2, .left-div3 { position:absolute; left:0; top:0;}
.right-div2, .right-div3 { clip:rect(0,auto,auto,100px);}
.left-div2, .left-div3 { clip:rect(0,100px,auto,auto);}
.right-div3 { background:#f00; transform:rotate(-180deg);}
.left-div3 { background:#f00; transform:rotate(-180deg);}
.div4 { position:absolute; top:25px; left:25px; width:150px; height:150px; line-height:150px; text-align:center; border-radius:50%; background:#fff;}
.div2 { left:300px; top:0; position:absolute; background:#ccc; width:200px; height:200px; border-radius:50%;}
js部分:
var progress = {
//变量
per : 0, //0~100
per_radian : 0, //0~360
right_div : null,
left_div : null,
num : null,
//函数
move : function (){
this.per_radian = this.per <= 50 ? this.per*3.6-180 : this.per*3.6-360;
if(this.per <= 50){
this.right_div.css(‘transform‘,‘rotate(‘ + this.per_radian + ‘deg)‘);
}else{
this.right_div.css(‘transform‘,‘rotate(0)‘);
this.left_div.css(‘transform‘,‘rotate(‘ + this.per_radian + ‘deg)‘);
}
this.num.html(this.per);
},
/*
*初始化
*参数1:进度
*参数2:右边的旋转对象
*参数3:左边的旋转对象
*参数4:显示进度的对象
*/
init : function(per, right, left, num){
this.per = per;
this.right_div = right;
this.left_div = left;
this.num = num;
this.move();
}
};
//调用
progress.init(90, $(‘.div1 .right-div3‘), $(‘.div1 .left-div3‘), $(‘.div1 .div4 span‘));
progress.init(30, $(‘.div2 .right-div3‘), $(‘.div2 .left-div3‘), $(‘.div2 .div4 span‘));标签:
