Question

我创建了一个具有数组属性＆＃39; icon-buttons＆＃39;的元素。我可以使用javascript传递数组但是当我在标记中传递它时，它不起作用。

属性：

＆＃13;

iconButtons: {
  type: Array,//tried Object as well
    value: function() { return []; }
}

＆＃13;

用法：

＆＃13;

<my-card heading="Demo 2" icon-buttons='[
                    {"name" : "edit", "icon" : "icons:create", "click" : "toggleMode();", "disabled" : false},
                    {"name" : "close", "icon" : "icons:clear", "click" : "alert(''close'');", "disabled" : false},
                    {"name" : "maximize", "icon" : "icons:fullscreen", "click" : "alert(''maximize'');", "disabled" : false},
                    {"name" : "more", "icon" : "icons:more-vert", "click" : "alert(''more'');", "disabled" : true}
                  ]'>
            <div class="card-content">
              <list mode="edit"></list>
            </div>
            <div class="card-actions">
              <paper-button>Hello</paper-button>
              <paper-button>Bye</paper-button>
            </div>
          </my-card>

＆＃13;

我已经为另一个元素传递了类似的JSON对象。但是这个带Array的功能不起作用。这有什么问题？

a1626是正确的，在您的提醒中使用\"代替''

... "click": "alert(\"close\");", ...

Polymer：通过标记将数组传递给property
