html - 如何将自定义图像添加到按钮 (dojo 1.7)

Question

如何将自定义图像添加到 dojo 按钮

这是没有图像的按钮的示例代码

<div id="zoomin" data-dojo-type="dijit.form.Button">
    <span>zoomin</span>
</div>

Answer 1

这些答案很接近，但您的图标的样式定义必须包括以下内容：

.myIcon {
  background-image: url(...);
  background-repeat: no-repeat;
  width: 16px;
  height: 16px;
  text-align: center;
}

Answer 2

您可以在小部件上设置图标类，然后在 css 中提供图像。

<div id="zoomin" data-dojo-type="dijit.form.Button" iconClass="myIcon">
    <span>zoomin</span>
</div>

.myIcon {
  background-image:  url(...);
}

Answer 3

遵循克雷格的回答，但要符合 1.7+ 和 html 标准，而是使用

<div id="zoomin" data-dojo-type="dijit.form.Button" data-dojo-props="iconClass:'myIcon'">
    <span>zoomin</span>
</div>

或者您可以通过函数覆盖来决定哪个

<div id="zoomin" data-dojo-type="dijit.form.Button">
    <script type="dojo/method" data-dojo-event="getIconClass">
         var regular = this.inherited(arguments);
         // this evaluation will allways be true, but here for sake of argument
         return (this.declaredClass == 'dijit.form.Button' ? "myButtonIcon" : regular);
    </script>
    <span>zoomin</span>
</div>

Answer 4

我使用 dojo 1.10 并使用 usingbackground-repeat:round

<div id="zoomin" data-dojo-type="dijit/form/Button" iconClass="myIcon">
<span>zoomin</span>

.myIcon {
 background-image:  url(...);
 background-repeat: round;
 width: 18px;
 height: 18px;
 text-align: center;
}
