Question

嗨，目前我用ember视图动态创建了一些按钮：



{{#each item in content._data.cpu_choices}}
                            {{#view App.CPUSelButView id=item value=item name="cpu_button" disabled=cpu_Not_Allow}}{{item}}x{{/view}}
                        {{/each

{{#each item in content._data.cpu_choices}} {{#view App.CPUSelButView id=item value=item name="cpu_button" disabled=cpu_Not_Allow}}{{item}}x{{/view}} {{/each

我的观点是 }

// View used for CPU selection buttons
App.CPUSelButView = Ember.View.extend({
    tagName: 'button',
    // class names, :emberbutton for CSS style
    classNameBindings: [':emberbutton', ':btn', ':btn-primary', ':btn-xs'],
    // html attributes, custom (e.g. name, value) should be defined here
    attributeBindings: ['disabled', 'name', 'value'],
    // on click
    click: function () {
    // for this controller, trigger the CPU_selection and send the value
        this.get('controller').send('cpu_selection', this.get('value'));
    }

我现在想要的是将id从item（动态）更改为some_stirng_item，使用前缀到当前id实际上有一种方法可以做到这一点。

我需要id来按ID搜索元素。

我通过将此添加到我的视图中解决了我的问题：



// Set this view's id 
    init: function() {
        this.set('elementId', "cpu_" + this.get('value'));
        return this._super();
    },

// Set this view's id init: function() { this.set('elementId', "cpu_" + this.get('value')); return this._super(); },

带有ember视图的动态按钮id some_String + button_value
