我有一个Ember前端,我想创建一个包含多个复选框的表单,不知何故,要么在检查时填充已检查项目的集合,要么在表单提交时收集选中的复选框
这就是我调用我的组件的方式
{{scheduled-report-form item=model buttonLabel=buttonLabel action='saveScheduledReport'}}
这是模板中发生的事情
{{#each item.vessels as |vessel|}}
<div>
<label class="custom-checkbox form-control-inline">
{{input type='checkbox' change=(action 'checkboxChangedVoice' item.scheduledReport vessel checkedVoice) selected=checkedVoice }}
<span>Voice</span>
</label>
<label class="custom-checkbox form-control-inline">
{{input type='checkbox' change=(action 'checkboxChangedData' item.scheduledReport vessel checkedData) checked=checkedData}}
<span>Data</span>
</label>
<span>{{vessel.name}}</span>
</div>
{{/each}}
.
.
.
<button type="submit" class="btn btn-main" {{action 'buttonClicked' item.scheduledReport item.user item.vessels }}>Generate report {{buttonLabel}}</button>
每个模型实例的复选框应为2,例如
Data Voice
[] [] Name1
[] [] Name2
我试图解决它的方式目前似乎不起作用
所以在我的组件中:
import Ember from 'ember';
export default Ember.Component.extend({
optionsData: [],
optionsVoice: [],
srOptions: [],
checkedVoice:false,
checkedData:false,
didInsertElemet() {
this.selectedItems = [];
},
actions: {
checkboxChangedVoice(options, vessel, paramValue) {
console.log(paramValue);
console.log(this.get('checkedVoice'));
//this populates an array with the checked boxes
this.get('optionsVoice').push(vessel);
console.log(this.get('optionsVoice'))
},
checkboxChangedData(options, vessel,paramValue) {
console.log(paramValue);
console.log(this.get('checkedData'));
//this populates an array with the checked boxes
this.get('optionsData').push(vessel);
console.log(this.get('optionsData'))
},
buttonClicked(paramsScheduledReport, paramsUser, srOptions) {
srOptions = this.get('srOptions')
this.sendAction('action', paramsScheduledReport, paramsUser, srOptions);
}
}
});
这也是控制器中的最后一个动作,以防有人发现它有用
import Ember from 'ember';
export default Ember.Controller.extend({
actions: {
saveScheduledReport(newScheduledReport, user , vessel) {
var controller = this;
console.log(vessel.toArray())
newScheduledReport.set('user', user);
newScheduledReport.set('vessels',vessel);
newScheduledReport.set('srOptions',vessel);
//TODO: Add recipients array from form!
newScheduledReport.set('reportRecipients',[])
newScheduledReport.save().then(function() {
controller.transitionToRoute('/');
});
},
}
});
现在,当我点击一个复选框时,组件中会发生什么:
console.log(paramValue)
将始终回答undefined
并且console.log(this.get('checkedVoice')
将始终回答false
目前您可能会注意到组件只是向数组附加值,我试图实现“切换”功能但我无法访问已检查的(true / false)值。
如果您认为我的实施完全没有,请建议任何其他可行的解决方案。
谢谢你们。答案 0 :(得分:2)
如果您正在处理余烬数据,您可以简单地将复选框绑定到每个容器的值&#34;数据&#34;或&#34;语音&#34;复选框(例如{{input type =&#39;复选框&#39; checked = vessel.checkedVoice}})然后在您准备就绪时保存模型。
但是针对您在阵列中跟踪它的具体要求。创建每个容器的对象数组会更简单。然后在表单提交上,您可以基于filterBy提交一组对象。
示例实施:
// scheduled-report-form.js
import Ember from 'ember';
export default Ember.Component.extend({
init() {
this._super(...arguments);
this.set('tempVessels', []);
this.get('item.vessels').forEach((vessel) => {
this.get('tempVessels').pushObject(Ember.Object.create({checkboxVoice: false, checkboxData: false, vessel: vessel}));
});
},
actions: {
buttonClicked() {
console.log('Voice array:');
console.log(this.get('tempVessels').filterBy('checkboxVoice', true));
console.log('Data array:');
console.log(this.get('tempVessels').filterBy('checkboxData', true));
}
}
});
// scheduled-report-form.hbs
{{#each tempVessels as |vessel|}}
// The sub-component isn't neccessary, just my design preference.
{{checkboxes-component vessel=vessel}}
{{/each}}
.
.
.
<button type="submit" class="btn btn-main" {{action 'buttonClicked'}}>Generate report {{buttonLabel}}</button>
// checkboxes-component.hbs
<label class="custom-checkbox form-control-inline">
{{input type='checkbox' checked=vessel.checkboxVoice}}
<span>Voice</span> = {{vessel.checkboxVoice}}
</label>
<label class="custom-checkbox form-control-inline">
{{input type='checkbox' checked=vessel.checkboxData}}
<span>Data</span> = {{vessel.checkboxData}}
</label>
<span>{{vessel.name}}</span>
