[英]Debug react JSX in vscode
I am creating a react app, and I need to see JSX at a specific point, so I started debugging using VSCode, I have my code like this: 我正在创建一个React应用,并且需要在特定位置查看JSX,所以我开始使用VSCode进行调试,我的代码如下:
render(): JSX.Element {
let result = (
<div className="footerComponent">
<DefaultButton className={commonStyles.defaultButton} onClick= {() => this.props.saveAllSettings()} >Save Changes</DefaultButton>
<DefaultButton className="" onClick = {() => this.setState({ dialogOpened: true})}>Discard Changes</DefaultButton>
{ this.state.dialogOpened && this.props.discardChangesDialog }
</div>
)
return result
}
I set a break point on the line : return result
and I log the value in the debugging console of vscode, but it's showing this: 我在行上设置了一个断点:
return result
并将该值记录在vscode的调试控制台中,但显示如下:
Object {$$typeof: Symbol(react.element), type: "div", key: null, ref: null, props: Object, …}
How do I view the exact JSX? 如何查看确切的JSX? Basically, I want to know what the expression
{ this.state.dialogOpened && this.props.discardChangesDialog }
returns. 基本上,我想知道表达式
{ this.state.dialogOpened && this.props.discardChangesDialog }
返回什么。
Here's what I see in the Watch window: 这是在“监视”窗口中看到的内容:
thanks. 谢谢。
render(): JSX.Element {
debugger;
this.state.dialogOpened;
this.props.discardChangesDialog
let result = (
<div className="footerComponent">
<DefaultButton className={commonStyles.defaultButton} onClick= {() => this.props.saveAllSettings()} >Save Changes</DefaultButton>
<DefaultButton className="" onClick = {() => this.setState({ dialogOpened: true})}>Discard Changes</DefaultButton>
{ this.state.dialogOpened && this.props.discardChangesDialog }
</div>
)
return result
}
Just add a debugger, and open the console. 只需添加一个调试器,然后打开控制台即可。
