1.新建文件 graceChecker.js

export default {
	error:'',
	check : function (data, rule){
		for(var i = 0; i < rule.length; i++){
			if (!rule[i].checkType){return true;}
			if (!rule[i].name) {return true;}
			if (!rule[i].errorMsg) {return true;}
			if (!data[rule[i].name]) {this.error = rule[i].errorMsg; return false;}
			switch (rule[i].checkType){
				case 'string':
					var reg = new RegExp('^.{' + rule[i].checkRule + '}$');
					if(!reg.test(data[rule[i].name])) {this.error = rule[i].errorMsg; return false;}
				break;
				case 'int':
					var reg = new RegExp('^(-[1-9]|[1-9])[0-9]{' + rule[i].checkRule + '}$');
					if(!reg.test(data[rule[i].name])) {this.error = rule[i].errorMsg; return false;}
					break;
				break;
				case 'between':
					if (!this.isNumber(data[rule[i].name])){
						this.error = rule[i].errorMsg;
						return false;
					}
					var minMax = rule[i].checkRule.split(',');
					minMax[0] = Number(minMax[0]);
					minMax[1] = Number(minMax[1]);

					var minMax = rule[i].checkRule.split(',');
					minMax[0] = Number(minMax[0]);

						this.error = rule[i].errorMsg;
						return false;
					}
				break;
				case 'same':
					if (data[rule[i].name] != rule[i].checkRule) { this.error = rule[i].errorMsg; return false;}
				break;
				case 'notsame':
					if (data[rule[i].name] == rule[i].checkRule) { this.error = rule[i].errorMsg; return false; }
				break;
				case 'email':
					var reg = /^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/;
					if (!reg.test(data[rule[i].name])) { this.error = rule[i].errorMsg; return false; }
				break;
				case 'phoneno':
					var reg = /^1[0-9]{10,10}$/;

				break;
				case 'in':
					if(rule[i].checkRule.indexOf(data[rule[i].name]) == -1){
						this.error = rule[i].errorMsg; return false;
					}
				break;
				case 'notnull':
					if(data[rule[i].name] == null || data[rule[i].name].length < 1){this.error = rule[i].errorMsg; return false;}
				break;
				case 'idcard':
					if(data[rule[i].name].length < 15 || data[rule[i].name].length > 15 && data[rule[i].name].length < 18){this.error = rule[i].errorMsg; return false;}
					if (data[rule[i].name].length == 15 && !(/^[1-9]\d{5}\d{2}((0[1-9])|(10|11|12))(([0-2][1-9])|10|20|30|31)\d{3}$/.test(data[rule[i].name]))) {
						this.error = rule[i].errorMsg; return false;
					}else if(data[rule[i].name].length == 18 && !(/^[1-9]\d{5}(18|19|([23]\d))\d{2}((0[1-9])|(10|11|12))(([0-2][1-9])|10|20|30|31)\d{3}[0-9Xx]$/.test(data[rule[i].name]))){
						this.error = rule[i].errorMsg; return false;
					}
				break;
				case 'address':
					var reg = /^[\u4e00-\u9fa5]/;
					if(!reg.test(data[rule[i].name])){
						this.error = rule[i].errorMsg; return false;
					}
				break;
			}
		}
		return true;
	},
	isNumber : function (checkVal){
		var reg = /^-?[1-9][0-9]?.?[0-9]*$/;
		return reg.test(checkVal);
	}
}

在原作者的基础上由加上了 idcard验证和address验证（实地地址的验证）

自定义定义rules：

let rules=[
	{
		name:'title',
		checkType: "string",
		checkRule: "1,30",
		errorMsg: "标题应为1-30个字符"
	}
]

然后引入graceChecker.js

<script>
	import graceChecker from "../../../common/graceChecker.js"
	export default{
		data(){
			return{}
		},
		methods:{
			formSubmit(e){
				let type = this.declareJson.type
				let rules = [
	              {
		            name:'title',
		            checkType: "string",
		            checkRule: "1,30",
		            errorMsg: "项目标题应为1-30个字符"
	              }
                ]
				//进行表单检查
				var formData = e.detail.value;
				var checkRes = graceChecker.check(formData, rules);
				if (checkRes) {
					uni.showToast({
						title: "验证通过!",
						icon: "none"
					});
				} else {
					uni.showToast({
						title: graceChecker.error,
						icon: "none"
					});
				}
			}
		}
	}
</script>

这样就可以根据自定义的校验信息进行校验及提示文章来源地址https://www.toymoban.com/news/detail-506595.html
