  • Why does vfor need to add key in vue?
    Why does vfor need to add key in vue?
    In Vue.js, v-for list items require a unique key attribute to track identification, optimize performance when data changes, and correctly move elements across lists. By setting a unique key, such as the ID or name of a list item, Vue can efficiently update the virtual DOM and avoid unnecessary re-rendering.

  • How to use foreach in vue
    How to use foreach in vue
    The v-for directive is used to iterate over an array or object and create corresponding DOM elements for each element. When iterating over an array, the syntax is v-for="item in items", where item is an alias for the current element. When traversing an object, the syntax is v-for="(value, key) in object", where key and value are the key and value respectively. The v-for directive also supports other features such as :key, v-bind, v-if, and v-else.

  • How to traverse objects with v-for in vue
    How to traverse objects with v-for in vue
    The v-for directive in Vue that traverses objects is implemented through the v-for="item in object" syntax. It allows traversing object properties and rendering template content. The specific usage is as follows: specify the traversed variable name item in v-for, which represents each value in the object. Access the properties of an object using person[item], where item is the property name. The v-for directive only iterates over the enumerable properties of an object, not the enumerable properties.

  • The role of created in vue
    The role of created in vue
    The role of the created() lifecycle hook in Vue.js is to obtain resources, such as data from a remote server or local storage. Initialize component state, such as setting default values or getting state from an external source. Set up observers to listen for state changes or external events. Update the DOM in special cases, such as inserting HTML fragments.

  • dispatch usage in vue
    dispatch usage in vue
    Dispatch is used in Vuex to submit mutations and trigger state changes to the store. The usage syntax is: this.$store.dispatch('mutationName', payload). The timing of use includes: when a component needs to trigger state changes in the store, when the same mutation needs to be triggered from multiple components, and when an asynchronous operation needs to be performed on the triggering of the mutation. Benefits include: allowing loose coupling between components, promoting testability, and improving code maintainability.
