我正在使用 reactVr 构建项目,并且在其中使用DOM元素时遇到问题。我遵循了来自Facebook的github上DomoverlaySample的示例,最终遇到了问题。基本上,在我的index.vr.js中,我将Monitor.js命名为 2D 图像。
import Monitor from './Monitor';
export default class Basics extends Component {
render() {
return (
<View>
<Pano source={asset('office.jpg')}/>
<Monitor />
<Printer />
<TryIframe />
</View>
);
}
}
然后在我的 Monitor.js 中复制并粘贴代码。
import React from 'react'
import {
Image,
View,
asset,
NativeModules,
VrButton,
Text,
Model,
VrHeadModel,
StyleSheet
} from 'react-vr'
import TextboxVr from './TextboxVr'; //calling from parent directory;
const domTextboxContent = {
header: "Test Header",
description: "The description goes here with. test description"
}
const vrTextboxContent = "DOM elements couldn't be loaded because your browser doesn't support DOM elements. ";
export default class Monitor extends React.Component {
constructor(){
super()
this.state = {
renderVrTextbox: false,
//infoText: false //setting the textField as false which will not display the box
}
this._toggleDisplay = this.toggleDisplay.bind(this);
}
toggleDisplay() {
if (VrHeadModel.inVR()) {
this.setState({renderVrTextbox: !this.state.renderVrTextbox});
} else {
// Not in VR, so let's use the dom overlay!
NativeModules.DomOverlayModule.openOverlay(domTextboxContent);
}
}
render() {
return (
<View >
<View style={styles.triggerContainer}>
<VrButton onClick={this._toggleDisplay}>
<Image
source={asset('infoButton.png')}
style={styles.imageView}></Image>
</VrButton>
</View>
{this.state.renderVrTextbox && <TextboxVr text={vrTextboxContent} />}
</View>
)
}
}
//.. some styleSheet goes here .. //
module.exports = Monitor;
每当我尝试运行代码时,都会抛出错误:openOverlay()
未定义,而openOverlay()
在DomOverlayModule.js
中定义。我假设NativeModule在 Monitor.js 中不起作用,并且无法解决该问题。任何帮助是极大的赞赏。
答案 0 :(得分:0)
我在这里发布自己的答案。我错过了从client.js
到DomOverlayModule.js
的桥梁,因此我在client.js中添加了此nativeModules: [domOverlayModule]
,此link中提供了此链接。我能够一遍又一遍地使用TextBoxOverlay.js类。下面是代码:
const vr = new VRInstance(bundle, 'Basics', parent, {
// Add custom options here
...options,
// Register dom overlay module upon initialization.
nativeModules: [domOverlayModule],
});
