ExtReact中传递参数的错误

Question

在传递属性的代码的这一部分中，可以在页面上呈现一次属性：

constructor(props){
    super(props);
    this.state = {
        idOfPortletLocation: props.portletlocationid
    };
}

render() { 



    const text = (
        <div>
            {this.props.text.description}
            {this.state.idOfPortletLocation}
        </div>
    );

……

正如你从截图中看到的：

证明

但是，代码的这一部分不识别属性idOfPortletLocation：

​

<Container padding={10} className="containerOfPanel"  flex = {1}/*style={{display: 'inline-block', position: 'absolute'}}*/> 
				<Panel 
					ref={panel => this.panel = panel}
					title= {this.props.text.title} 
					/*height= {this.props.height}*/
					/*minHeight = {this.props.height}*/

					tools={[ 
						{type: 'minimize', handler: this.toolHandler},
						{type: 'maximize', handler: (e) => this.toolHandler(e, this.state.idOfPortletLocation) }, 
						{type: 'close', handler: this.toolHandler }
					]}
					resizable={{
						edges: "all", 
					}} 
					bodyPadding={10}
				>
					{text} 
				</Panel>
			</Container> 

​

以及：

toolHandler(owner, tool, idOfPortletLocation) { 

    console.log(tool.config.type);
    console.log(idOfPortletLocation); /* Here it is not recognized */

    if(tool.config.type.valueOf() == "close"){
        console.log("passed");
    }
}

Answer 1

处理程序：(e) => this.toolHandler(e，this.state.idOfPortletLocation) //这里只传递两个参数，idOfPorletLocation作为第二个参数//但在toolHandler中有三个参数，idOfPorletLocation作为第三个参数，但作为第二个参数被传递。

所以正确的功能应该是-

toolHandler(tool, idOfPortletLocation) { 

console.log(tool.config.type);
console.log(idOfPortletLocation); /* Here it is now recognized */

if(tool.config.type.valueOf() == "close"){
    console.log("passed");
}

让我知道它是否对你有用)
