The parent component can dynamically change the properties passed to the child component as needed, achieving the effect of dynamically rendering the child component. For example:<\/li>\n<\/ol>\n<pre class=\"post-pre\"><code><span class=\"hljs-comment\">\/\/ \u7236\u7ec4\u4ef6<\/span>\r\n<span class=\"hljs-keyword\">function<\/span> <span class=\"hljs-title function_\">ParentComponent<\/span>(<span class=\"hljs-params\"><\/span>) {\r\n  <span class=\"hljs-keyword\">const<\/span> data = <span class=\"hljs-string\">'Hello World'<\/span>;\r\n  <span class=\"hljs-keyword\">return<\/span> <span class=\"language-xml\"><span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">ChildComponent<\/span> <span class=\"hljs-attr\">data<\/span>=<span class=\"hljs-string\">{data}<\/span> \/&gt;<\/span><\/span>;\r\n}\r\n\r\n<span class=\"hljs-comment\">\/\/ \u5b50\u7ec4\u4ef6<\/span>\r\n<span class=\"hljs-keyword\">function<\/span> <span class=\"hljs-title function_\">ChildComponent<\/span>(<span class=\"hljs-params\">props<\/span>) {\r\n  <span class=\"hljs-keyword\">return<\/span> <span class=\"language-xml\"><span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">div<\/span>&gt;<\/span>{props.data}<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">div<\/span>&gt;<\/span><\/span>;\r\n}\r\n<\/code><\/pre>\n<ol>\n<li>Context passing: With React&#8217;s context functionality, a parent component can pass data to a child component for rendering. Unlike passing props, context passing can traverse multiple levels of components without the need to pass through props layer by layer. However, context passing may increase coupling between components, so it is important to carefully consider the use cases and component relationships when using context passing. For example:<\/li>\n<\/ol>\n<pre class=\"post-pre\"><code><span class=\"hljs-comment\">\/\/ \u7236\u7ec4\u4ef6<\/span>\r\n<span class=\"hljs-keyword\">class<\/span> <span class=\"hljs-title class_\">ParentComponent<\/span> <span class=\"hljs-keyword\">extends<\/span> <span class=\"hljs-title class_ inherited__\">React.Component<\/span> {\r\n  <span class=\"hljs-keyword\">static<\/span> childContextTypes = {\r\n    <span class=\"hljs-attr\">data<\/span>: <span class=\"hljs-title class_\">PropTypes<\/span>.<span class=\"hljs-property\">string<\/span>\r\n  };\r\n\r\n  <span class=\"hljs-title function_\">getChildContext<\/span>(<span class=\"hljs-params\"><\/span>) {\r\n    <span class=\"hljs-keyword\">return<\/span> {\r\n      <span class=\"hljs-attr\">data<\/span>: <span class=\"hljs-string\">'Hello World'<\/span>\r\n    };\r\n  }\r\n\r\n  <span class=\"hljs-title function_\">render<\/span>(<span class=\"hljs-params\"><\/span>) {\r\n    <span class=\"hljs-keyword\">return<\/span> <span class=\"language-xml\"><span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">ChildComponent<\/span> \/&gt;<\/span><\/span>;\r\n  }\r\n}\r\n\r\n<span class=\"hljs-comment\">\/\/ \u5b50\u7ec4\u4ef6<\/span>\r\n<span class=\"hljs-keyword\">class<\/span> <span class=\"hljs-title class_\">ChildComponent<\/span> <span class=\"hljs-keyword\">extends<\/span> <span class=\"hljs-title class_ inherited__\">React.Component<\/span> {\r\n  <span class=\"hljs-keyword\">static<\/span> contextTypes = {\r\n    <span class=\"hljs-attr\">data<\/span>: <span class=\"hljs-title class_\">PropTypes<\/span>.<span class=\"hljs-property\">string<\/span>\r\n  };\r\n\r\n  <span class=\"hljs-title function_\">render<\/span>(<span class=\"hljs-params\"><\/span>) {\r\n    <span class=\"hljs-keyword\">return<\/span> <span class=\"language-xml\"><span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">div<\/span>&gt;<\/span>{this.context.data}<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">div<\/span>&gt;<\/span><\/span>;\r\n  }\r\n}\r\n<\/code><\/pre>\n<p>These are two commonly used ways to render parent and child components, developers can choose the appropriate method based on their specific needs.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In React, rendering between parent and child components can be achieved through two methods.
