Vue中使用el-checkbox时遇上这样的错误： TypeError: Cannot read property ‘length’ of undefined at VueComponent.isLimitDisabled (element-ui.common.js?ccbf:6452) at Watcher.get (vue.esm.js?efeb:4482) at Watcher.evaluate (vue.esm.js?efeb:4587) at VueComponent.computedGetter [as isLimitDisabled] (vue.esm.js?efeb:4839) at VueComponent.isDisabled (element-ui.common.js?ccbf:6455) at Watcher.get (vue.esm.js?efeb:4482) at Watcher.evaluate (vue.esm.js?efeb:4587) at VueComponent.computedGetter [as isDisabled] (vue.esm.js?efeb:4839) at Object.get (vue.esm.js?efeb:2104) at Proxy.checkboxvue_type_template_id_d0387074_render (element-ui.common.js?ccbf:6161) 解决方案： 检查el-checkbox上，v-model绑定的字段名，与data中的属性名，是否一致. 注: 区分大小写 检查代码，发现就是属性名不一致，修改后，解决 |
