【问题描述】:
这是我的代码逻辑,当用户点击该框时,我会将状态active设置为true
和getCssStyle() 将返回drag-and-resize-box-text clicked
然后背景图像(T)应该消失
class Box extends Component {
constructor(props) {
super(props);
this.state = {
active: false,
}
}
// decide which style to be used
getCssStyle = (type) => {
switch (type) {
case 'text':
if (this.state.active) {
console.log("AAA")
return 'drag-and-resize-box-text clicked'
} else {
console.log("BBB")
return 'drag-and-resize-box-text';
}
// break;
default:
return '';
}
}
onClick = () => {
this.setState({active: true});
}
render() {
return (
<div className={this.getCssStyle(boxType)} >
{this.boxFillContent()}
</div>
</div>
);
}
}
开发工具显示背景图片已删除,但页面仍显示图片
这有什么问题??
css
.drag-and-resize-box-text{
border: dashed 3px LightSeaGreen;
background: url(../images/bottom/text_normal.png) no-repeat;
background-position:center;
width: inherit;
height: inherit;
}
.drag-and-resize-box-text.clicked{
border: dashed 3px LightSeaGreen;
/*background: url(../images/bottom/text_normal.png) no-repeat;*/
background-position:center;
width: inherit;
height: inherit;
}
