我想監(jiān)聽ruleForm對(duì)象的moduleDir屬性，根據(jù)屬性值得變化，修改ruleForm對(duì)象的另一個(gè)屬性genModules。但發(fā)生了死循環(huán)。代碼如下：watch:{ruleForm:{handler(newVal){console.log(this);//以下代碼造成死循環(huán)if('/common'===newVal.moduleDir){this.ruleForm.genModules=["modelAndMapper","repository","service"];}elseif('/api'===newVal.moduleDir){this.ruleForm.genModules=["controller"];}elseif('/web'===newVal.moduleDir){this.ruleForm.genModules=["controllerAndPage"];}},deep:true,immediate:true}}
