elementui的el-input校验

1、输入框中只能输入中文

rules: {
        title: [
          { required: true, message: "请输入中文的标题", trigger: "blur" },
          {
            validator: function(rule, value, callback) {
              //校验中文的正则：/^[\u4e00-\u9fa5]{0,}$/
              if (/^[\u4e00-\u9fa5]+$/.test(value) == false) {
                callback(new Error("请输入中文"));
              } else {
                //校验通过
                callback();
              }
            },
            trigger: "blur"
          }
        ],
}

2、输入框中只能输入英文

rule:[
   subsysShow: [
          { required: true, message: "请输入英文的组件名", trigger: "blur" },
          {
            validator: function(rule, value, callback) {
              //  校验英文的正则
              if (/[a-zA-z]$/.test(value) == false) {
                callback(new Error("请输入英文"));
              } else {
                //校验通过
                callback();
              }
            },
            trigger: "blur"
          }
        ],
]
