Ember绑定一个值 [英] Ember binding a value

问题描述

我一直在尝试在Ember中绑定一个值，这样当我提交我的表单时，在下面的单选按钮列表中选择的值会出现在POST请求中，但是我遇到了一些麻烦你们可以帮忙吗？ br $>


查看radio.js：

I've been trying to bind a value in Ember so that when I submit my form the value selected on the following Radio Button List goes on the POST request, but I've been having some trouble can you guys help?

View radio.js:

Ember.Radio = Ember.View.extend({
    tagName: "input",
    type: "radio",
    attributeBindings: ["name", "type", "value", "checked:checked:"],
    click: function () {
        this.set("selection", this.$().val())

        if(this.get("selection") === "acRequired") {
            $('#panelAccommodation').css("display", "block");
            this.set("selection", "Required");
            selectionBinding: "App.event.accommodation"
        }
        if (this.get("selection") === "acNotRequired") {
            $('#panelAccommodation').css("display", "none");
            this.set("selection", "Not Required");
            selectionBinding: "App.event.accommodation"
        }
        if (this.get("selection") === "flRequired") {
            $('#panelFlight').css("display", "block");
            this.set("selection", "Required");
            selectionBinding: "App.event.flight"
        }
        if (this.get("selection") === "flNotRequired") {
            $('#panelFlight').css("display", "none");
            this.set("selection", "Not Required");
            selectionBinding: "App.event.flight"
        }
    },

    checked: function () {
        return this.get("value") == this.get("selection");
    }.property()
});

Index.html：

Index.html:

<div class="form-group">
                                    <label for="accommodation">3.2. ACCOMMODATION (*)</label> <br />
                                    <div>
                                        {{view Ember.Radio name="accommodation" selectionBinding='accommodation' value="acNotRequired"}}
                                        Not Required
                                    </div>
                                    <div>
                                        {{view Ember.Radio name="accommodation" selectionBinding='accommodation' value="acRequired"}}
                                        Required
                                    </div>
                                </div>

控制器new.js：

controller new.js:

App.EventsNewController = Ember.ObjectController.extend({

    accommodation: "Not Required",
    flight: "Not Required",

推荐答案

（）。val（））

if （this.get（ selection）=== acRequired）{

().val()) if(this.get("selection") === "acRequired") {

（' ＃panelAccommodation'）。css（ 显示， block）;
this。 set （ selection， 必需）;
selectionBinding： App.event.accommodation
}
if （this.get（ selection）=== acNotRequired）{

('#panelAccommodation').css("display", "block"); this.set("selection", "Required"); selectionBinding: "App.event.accommodation" } if (this.get("selection") === "acNotRequired") {

（ ' ＃panelAccommodation'）。css（ display， none） ;
this。 set （ selection， 不需要）;
selectionBinding： App.event.accommodation
}
if （this.get（ selection）=== flRequired）{

('#panelAccommodation').css("display", "none"); this.set("selection", "Not Required"); selectionBinding: "App.event.accommodation" } if (this.get("selection") === "flRequired") {
