mpvue项目的自定义数字键盘

这段时间一直在做小程序项目（基于mpvue）
抽空做个笔记

自定义的数字键盘

鉴于使用系统自带输入键盘会造成挤压页面等问题，同时也不能满足设计需求，因此自己去写了个键盘组件。
效果如下：

页面代码

script内容

export default {
  name: 'number-keyboard',
	props: {
		open: {
			type: Boolean,
			default: false
		},
		color: {
			type: String,
			default: '#04BE02'
		}
	},
	data() {
		return {
			config :{
				loop : [
					{
						number : 1,
						key : 'number-1',
					},
					{
						number : 2,
						key : 'number-2',
					},
					{
						number : 3,
						key : 'number-3',
					},
					{
						number : 4,
						key : 'number-4',
					},
					{
						number : 5,
						key : 'number-5',
					},
					{
						number : 6,
						key : 'number-6',
					},
					{
						number : 7,
						key : 'number-7',
					},
					{
						number : 8,
						key : 'number-8',
					},
					{
						number : 9,
						key : 'number-9',
					},
				]
			},
			showKeyBoard: this.open
		};
	},
	watch: {
		showKeyBoard: function(value, oldValue) {
			if (value == false) {
				this.$emit('close');
			}
		},
		open: function(value, oldValue) {
			console.log(value);
			this.showKeyBoard = value;
		}
	},
	methods: {
		close(){
			this.showKeyBoard = false;
			this.$emit("close");
		},
		del() {
			this.$emit("delete");
		},
		number(number) {
			this.$emit("number", number);
		}
	}
}
