Question

我如何自定义图像添加到道场按钮

这里是按钮的代码示例没有图像

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

Answer 1

您可以设置一个图标类，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 2

跟踪Craig的答案，但有1.7+和HTML标准的要求，而不是使用

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

或者你可以决定通过函数覆盖

<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 3

这些答案很接近，但图标的样式定义必须包含以下内容：

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

Answer 4

我使用道场1.10和工作与使用background-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; 
}
