我想用VUE和LARAVEL構建一個表單,用戶可以在其中動態地構建參與者組。我決定解決這個問題,讓用戶爲每個組生成一個表格。在每張桌子內部,她/他可以添加和刪除行。動態創建組件的父子通信
到現在爲止,我得到了這一點:
家長HTML:
<div class="form-group col-md-12 blocco-partecipante" v-for="participant_block in participant_blocks">
<mimi-table :operators='operators' :participant_block='participant_block' @removeBlockParticipant="removeBlockParticipant" @makeBlockWinner="makeBlockWinner"></mimi-table>
</div>
STYLE.JS
Vue.component('mimi-table', {
props: ['operators', 'participant_block'],
template: '\
<div>\
<div class="row">\
<div class="col-xs-6"><button type="button" class="btn btn-default" @click.prevent="makeBlockWinner">Winner</button></div>\
<div class="col-xs-6"><button type="button" class="btn btn-danger pull-right" @click.prevent="removeBlockParticipant">Remove Block</button></div>\
</div>\
<table class="table table-bordered" id="participants-table" v-model="participant_block">\
<thead>\
<tr>\
<th>#</th>\
<th>Operator</th>\
<th>Head Operator</th>\
<th></th>\
</tr>\
</thead>\
<tbody>\
<tr v-for="(row, index) in rows" track-by="index">\
<th>{{ index + 1 }}</th>\
<td>\
<select style="width: 100%" v-model="row.selected">\
<option v-for="operator in operators" :selected="(row.selected == operator.name)">{{ operator.name}}</option>\
</select>\
</td>\
<td>\
<input type="checkbox" name="head" v-model="row.head_operator" @click="selectHeadOperator(index)"/>\
</td>\
<td>\
<input type="button" class="ibtnDel btn btn-md btn-danger" @click="removeOperator(index)" value="Remove" />\
</td>\
</tr>\
</tbody>\
<tfoot>\
<tr>\
<td colspan="4" style="text-align: left;">\
<input type="button" class="btn btn-lg btn-block" value="Add Operator to Participant Block" @click="addOperator"/>\
</td>\
<tr>\
<tr>\
</tr>\
</tfoot>\
</table>\
</div>\
',
data: function() {
return {
rows : [
]
}
},
methods: {
addOperator: function() {
this.rows.splice(this.rows.length, 0, {});
if (this.rows.length == 1)
this.rows[0].head_operator = true;
},
removeOperator: function(value) {
this.rows.splice(value, 1);
},
selectHeadOperator: function(index) {
this.rows.forEach(function(row, counter) {
if (counter != index) row.head_operator = false;
});
},
removeBlockParticipant: function() {
this.$emit('removeBlockParticipant');
},
makeBlockWinner: function() {
this.$emit('makeBlockWinner');
}
}
});
new Vue({
el: '#main-form',
data: {
participant_blocks: [],
operators: [],
index: 0
},
mounted: function() {
vm = this;
axios.get('/operators').then((response) => {
vm.operators = response.data;
});
},
methods: {
addBlockParticipant: function() {
this.participant_blocks.splice(this.participant_blocks.length, 0, {});
},
removeBlockParticipant: function() {
console.log('test 1');
},
makeBlockWinner: function() {
console.log('test 2');
},
} });
1)$發出的組件不火的消息父母。 removeBlockParticipant和makeBlockWinner它們不記錄消息。我不明白爲什麼。是否因爲這些組件是動態創建的,所以我必須使用另一個系統?
2)我正面臨的另一個問題是,我想在每個select動態創建的select輸入上使用庫select2.js。是否有可能在我寫這封信,這意味着系統應用此庫,是有可能:
$('#component').select()
是非常選擇之前創建?就像Jquery「.on()」一樣?
