一定要在自定义规则之后加上else{callback()}
demo
js逻辑
{内容，8}和{内容}来区分
也可以用正则匹配
{内容，8}{([\u4E00-\u9FA5]|[1-9]| |[a-z]){1,4}(,|，){1}\d*}
{内容} {([\u4E00-\u9FA5]|[1-9]|[a-z]|\d| ){1,3}
rules = {
content: [{
validator: this.validatePass, trigger: ['blur'] }],};
validatePass(rule: any, value: any, callback: any) {
this.commaIndex = [];
if (value.length == 0) {
callback(new Error('请重新输入模板内容'));
}
this.leftIndex = value.indexOf('{');
this.rightIndex = value.indexOf('}');
value.split('').forEach((item: string, index: number) => {
if (item == ',') {
this.commaIndex.push({
index: index, name: item });
}
if (item == '，') {
this.commaIndex.push({
index: index, name: item });
}
});
if (this.form.varType == 1) {
//具名{内容，8}
if (this.leftIndex != -1) {
if (this.commaIndex.length == 0) {
callback(new Error('请输入符合模板规则的内容'));
} else {
let temp = 0;
this.commaIndex.forEach((item, index) => {
if (this.leftIndex < item.index && this.rightIndex > item.index) {
temp++;
}
});
if (temp > 0) {
callback();
} else {
callback(new Error('请输入符合模板规则的内容'));
}
console.log(temp, 'temp');
}
} else {
callback(new Error('请输入符合模板规则的内容'));
}

//正常模式{内容，8}
