Vue JS - 输入值文本未更新
Vue JS - Input value text is not updating
我有一个输入组件,当在父级中注册时,该值绑定到一个变量 'searchText'。 searchText 保存搜索输入的文本值。当我在模板中查看 {{searchText}} 时,变量将相应更新。我还试图通过单击按钮来设置输入值。我有一个位置列表,当我 select 其中一个位置时,我想更新输入的值。我的问题是,尽管值 {{searchText}} 正在根据我单击的项目的文本进行更新,但它不会更新我输入的文本。
如何将输入的文本也设置为更新后的点击项的文本?
Search.vue
//Template
<div class="location-search-wrapper">
{{searchText}} // This updates both when I type and also when I select the item
<SearchInput :type="'text'"
:value="searchText"/> // Here the value does not update when I click the item
<div v-if="LocationSuggestionBox" class="search-suggestions">
<LocationSuggestionBox :popular-suggestions="popularSuggestions"
:city-list="searchResults"
:select-location="selectLocation"/>
</div>
</div>
//Script:
// Here the value of search text is updated according to the location selected
function selectLocation(location) {
if (location) {
searchText.value = location
}
}
SearchInput.vue
//Template
<input ref="inputField"
:type="type"
:id="fieldName"
:name="fieldName"
:placeholder="placeholder"
v-model="input"
class="form-input"/>
// Script:
const input = ref('');
(function setValueOnCreate() {
if (props.value) {
input.value = props.value;
}
})();
LocationList.vue
//Template
<div class="location-suggestion-box">
<div v-for="(city, i) in cityList"
:key="i"
:value="city"
@click="selectLocation(city)"
class="suggestion-item">
{{ city }}
</div>
</div>
// script:
props: {
cityList: {
type: Array,
required: false
},
selectLocation: {
type: Function,
required: false
}
},
尝试观察 value prop 而不是使用 IIFE :
import {watch,ref,.....} from 'vue'
....
const input = ref('');
watch(()=>props.value,(val){
if(val){
input.value = val;
}
})
