我已经和这个斗争了太久了。如果取决于我的侧边栏是否隐藏,我需要能够更改网格的宽度。我只需要知道如何提供像素信息来更改大小。
这是我的代码:
import GridLayout,{ WidthProvider, Responsive } from "react-grid-layout";
import _ from "lodash";
const ResponsiveReactGridLayout = WidthProvider(Responsive);
class DashboardContainer extends React.PureComponent {
static defaultProps = {
className: "layout",
//breakpoints: {lg: 1200, md: 996, sm: 768, xs: 480, xxs: 0},
cols: { lg: 12, md: 10, sm: 5, xs: 4, xxs: 2 },
width: 1000 - 160,
rowHeight: 100,
//verticalCompact: false
};
constructor(props) {
super(props);
console.log(props);
console.log('responsive' + Responsive);
this.state = {
items: numWidgetsArray(this.props.numWidgets).map(function(i, key, list) {
return {
i: i.toString(),
x: i * 2,
y: 0,
w: 2,
h: 2,
add: i === (list.length - 1)
};
}),
newCounter: 0
};
this.onAddItem = this.onAddItem.bind(this);
this.onBreakpointChange = this.onBreakpointChange.bind(this);
this.onLayoutChange = this.onLayoutChange.bind(this);
}
//() => {this.onRemoveItem.bind(this, i);; this.props.setWidgetEvent('removeWidget'); this.props.saveNumWidgets(this.props.numWidgets - 1)}
createElement(el) {
const removeStyle = {
position: "absolute",
right: "2px",
top: 0,
cursor: "pointer"
};
const i = el.add ? el.i : el.i;
return (
<div key={i} data-grid={el} style={{backgroundColor:'blue'}}>
{/* {el.add ? (
<span
className="add text"
onClick={this.onAddItem}
title="You can add an item by clicking here, too."
>
Add +
</span>
) : ( */}
<span className="text"><WidgetTile/></span>
{/* )} */}
<span
className="remove"
style={removeStyle}
onClick={() => {this.props.setSettingsOpen(!this.props.settingsOpen)}}
>
S
</span>
</div>
);
}
onAddItem() {
/*eslint no-console: 0*/
console.log("adding", "n" + this.state.newCounter);
this.setState({
// Add a new item. It must have a unique key!
items: this.state.items.concat({
i: "n" + this.state.newCounter,
x: (this.state.items.length * 2) % (this.state.cols || 12),
y: Infinity, // puts it at the bottom
w: 2,
h: 2
}),
// Increment the counter to ensure key is always unique.
newCounter: this.state.newCounter + 1
});
}
// We're using the cols coming back from this to calculate where to add new items.
onBreakpointChange(breakpoint, cols) {
console.log('breakpoint: ' + breakpoint);
console.log(cols);
this.setState({
breakpoint: breakpoint,
cols: cols
});
}
onLayoutChange(layout) {
//this.props.onLayoutChange(layout);
console.log(layout);
this.setState({ layout: layout });
}
onRemoveItem(i) {
console.log("removing", i);
this.setState({ items: _.reject(this.state.items, { i: i }) });
}
componentDidUpdate(){
if(this.props.widgetEvent === 'addWidget'){
this.onAddItem();
this.props.setWidgetEvent('');
}
else if(this.props.widgetEvent === 'removeWidget'){
this.setState({items: numWidgetsArray(this.props.numWidgets).map(function(i, key, list) {
return {
i: i.toString(),
x: i * 2,
y: 0,
w: 2,
h: 2,
add: i === (list.length - 1)
};
})})
this.props.setWidgetEvent('');
}
}
render() {
return (
<div>
<ResponsiveReactGridLayout
onLayoutChange={this.onLayoutChange}
onBreakpointChange={this.onBreakpointChange}
{...this.props}
>
{_.map(this.state.items, el => this.createElement(el))}
</ResponsiveReactGridLayout>
{this.props.settingsOpen ? <SettingsWindow/> : ''}
</div>
);
}
}
export default DashboardContainer;
不管我看过什么,我都不明白如何让它工作。谢谢你。
