📖 规则详情

此规则在以下情况下报告 v-bind 指令上的 .sync 修饰符：

¥This rule reports .sync modifier on v-bind directives in the following cases:

.sync 修饰符没有作为 LHS 有效的属性值。例如<MyComponent v-bind:aaa.sync="foo() + bar()" />, <MyComponent v-bind:aaa.sync="a?.b" />
¥The .sync modifier does not have the attribute value which is valid as LHS. E.g. <MyComponent v-bind:aaa.sync="foo() + bar()" />, <MyComponent v-bind:aaa.sync="a?.b" />
.sync 修饰符具有潜在的空对象属性访问。例如<MyComponent v-bind:aaa.sync="(a?.b).c" />
¥The .sync modifier has potential null object property access. E.g. <MyComponent v-bind:aaa.sync="(a?.b).c" />
.sync 修饰符在非 Vue 组件上。例如<input v-bind:aaa.sync="foo"></div>
¥The .sync modifier is on non Vue-components. E.g. <input v-bind:aaa.sync="foo"></div>
.sync 修饰符的引用是迭代变量。例如<div v-for="x in list"><MyComponent v-bind:aaa.sync="x" /></div>
¥The .sync modifier's reference is iteration variables. E.g. <div v-for="x in list"><MyComponent v-bind:aaa.sync="x" /></div>
