这可能是非常简单的事情,但我现在无法弄明白。我有一个带有各种按钮的聚合物纸 - 收音机组,但是在第二次点击之前不会进行选择。
<paper-radio-group selected="{{radioSelected}}" on-change="viewChanger">
<paper-radio-button name="none">None</paper-radio-button>
<paper-radio-button name="sidebyside">Side by side</paper-radio-button>
<paper-radio-button name="popup">Pop-up</paper-radio-button>
</paper-radio-group>
和JS:
Polymer({
is: 'x-menu',
properties: {
radioSelected: {
type: String,
value: "none"
}
},
viewChanger: function() {
console.log(this.radioSelected);
}
});
感谢您的帮助。我是Polymer的新手。

更好地尝试:
<paper-radio-group selected="{{radioSelected}}">
<paper-radio-button name="none">None</paper-radio-button>
<paper-radio-button name="sidebyside">Side by side</paper-radio-button>
<paper-radio-button name="popup">Pop-up</paper-radio-button>
</paper-radio-group>
你的JS:
Polymer({
is: 'x-menu',
properties: {
radioSelected: {
type: String,
value: "none",
observer: '_radioGroupChanged'
}
},
_radioGroupChanged: function(radioSelected) {
console.log(radioSelected);
}
});
