0-100分数验证:
var examRule = function(rule, value, callback) { //分数验证
if(value != '' && value != null){
let examScore = parseInt(value);
if(examScore < 0 || examScore > 100){
callback(new Error('请输入正确的考试成绩'));
}else{
callback();
}
}else{
callback();
}
};

{ validator: examRule, trigger: 'blur'},//examRule:0-100验证
{ validator: IsInteger, trigger: 'blur'},//IsInteger:正整数验证
]
