组件开发
设计思路
数字的主体是一个二维数组组成的图形，通过数组中的值来控制具体块的展示形式。
//如0的本质是这样的一个二维数组
[[1,1,1],
[1,0,1],
[1,0,1],
[1,0,1],
[1,1,1]]
入参
//要转化的数字
numbers: {
type: Array,
default: [0,22]
},
//数字主体颜色
numberColor: {
type: String,
default: 'black'
},
//数字尺寸
numberSize:{
type: String,
default: '1rem'
}
主要函数
将数字转换为二维数组
getNumber(num){
switch (num.toString()){
case '0':
return [
[1,1,1],
[1,0,1],
[1,0,1],
[1,0,1],
[1,1,1],
];
break;
case '1':
return [
[0,1,0],
[0,1,0],
[0,1,0],
[0,1,0],
[0,1,0],
];
break;
………………
………………
default :
break;
}
return [];
}
修改块元素样式
rowStyle(row){
let res = `width:calc(${this.numberSize}/5);height:calc(${this.numberSize}/5);`;
if(row == 1){
res += `background-color: ${this.numberColor};`;
}
return res;
},
将字符串转换成二维数组
getShowNum(num){
num = num.toString();
let res = [];
for(let i = 0; i < num.length; i++){
let temp = this.getNumber(num[i]);
if(num[i] != 1){
for(let j = 0; j < temp.length; j++){
temp[j].push(0);
}
}
if(res.length == 0) res = temp;
else{
for(let j = 0; j < res.length; j++){
res[j] = res[j].concat(temp[j]);
}
}
}
return res;
}
