what is the prop of each form item? And the arrow function (rule, value, callback) how are these three parameters passed in? The example given does not understand at all
<el-form :model="ruleForm2" status-icon :rules="rules2" ref="ruleForm2" label-width="100px" class="demo-ruleForm">
<el-form-item label="" prop="pass">
<el-input type="password" v-model="ruleForm2.pass" autocomplete="off"></el-input>
</el-form-item>
<el-form-item label="" prop="checkPass">
<el-input type="password" v-model="ruleForm2.checkPass" autocomplete="off"></el-input>
</el-form-item>
<el-form-item label="" prop="age">
<el-input v-model.number="ruleForm2.age"></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary" @click="submitForm("ruleForm2")"></el-button>
<el-button @click="resetForm("ruleForm2")"></el-button>
</el-form-item>
</el-form>
<script>
export default {
data() {
var checkAge = (rule, value, callback) => {
if (!value) {

setTimeout(() => {

callback(new Error(""));
} else {
if (value < 18) {
callback(new Error("18"));
} else {
callback();
}
}
}, 1000);
};
var validatePass = (rule, value, callback) => {
if (value === "") {
callback(new Error(""));
} else {
if (this.ruleForm2.checkPass !== "") {
this.$refs.ruleForm2.validateField("checkPass");

callback();
