This rule checks whether every v-else-if directive is valid.

📖 Rule Details

This rule reports v-else-if directives in the following cases:

• The directive has that argument. E.g. <div v-if="foo"></div><div v-else-if:aaa="bar"></div>
• The directive has that modifier. E.g. <div v-if="foo"></div><div v-else-if.bbb="bar"></div>
• The directive does not have that attribute value. E.g. <div v-if="foo"></div><div v-else-if></div>
• The directive is on the elements that the previous element don't have v-if/v-else-if directives. E.g. <div v-else-if="bar"></div>
• The directive is on the elements which have v-if/v-else directives. E.g. <div v-if="foo" v-else-if="bar"></div>
