我一直在關注vue js wrapper component example.我試圖改變這種工作方式,以允許我將v-select2
指令添加到常規選擇框,而不必爲每個指令創建模板和組件。我有一個JS Bin這裏顯示使用該組件。以Vue Js爲指令的Select2
組件html如下(在JS中設置選項)。
<div id="app"></div>
<script type="text/x-template" id="demo-template">
<div>
<p>Selected: {{ selected }}</p>
<select2 :options="options" v-model="selected">
<option disabled value="0">Select one</option>
</select2>
<p>Selected: {{ selected2 }}</p>
<select2 :options="options" v-model="selected2">
<option disabled value="0">Select one</option>
</select2>
<p>Selected: {{ selected3 }}</p>
<select2 :options="options" v-model="selected3">
<option disabled value="0">Select one</option>
</select2>
</div>
</script>
<script type="text/x-template" id="select2-template">
<select>
<slot></slot>
</select>
</script>
隨着JS如下:
Vue.component('select2', {
props: ['options', 'value'],
template: '#select2-template',
mounted: function() {
var vm = this
$(this.$el)
.val(this.value)
// init select2
.select2({ data: this.options })
// emit event on change.
.on('change', function() {
vm.$emit('input', this.value)
})
},
watch: {
value: function (value) {
// update value
$(this.$el).val(value)
},
options: function (options) {
// update options
$(this.$el).select2({ data: options })
}
},
destroyed: function() {
$(this.$el).off().select2('destroy')
}
})
var vm = new Vue({
el: '#app',
template: '#demo-template',
data: {
selected: 0,
selected2: 0,
selected3: 0,
options: [
{ id: 1, text: 'Hello' },
{ id: 2, text: 'World' }
]
}
})
我要的是像下面
<div id="app">
<p>Selected: {{ selected }}</p>
<select name="selected1" id="selected1" class="select2" v-selectize v-model="selected">
... options here ...
</select>
<p>Selected: {{ selected2 }}</p>
<select name="selected2" id="selected2" class="select2" v-selectize v-model="selected2">
... options here ...
</select>
<p>Selected: {{ selected3 }}</p>
<select name="selected3" id="selected3" class="select2" v-selectize v-model="selected3">
... options here ...
</select>
</div>
我試圖讓它作爲一個指令工作,所以我不必將它用作組件。 –
