我从localStorage读取Draft.js原始内容时遇到问题。
我想使用以前存储的rawContent作为我的initialState用于reducer。
我认为convertFromRaw功能是我的问题。我默默地粉碎（不登录到控制台），我不知道如何解决这个问题。
我在localStorage中持久保存Draft.js原始内容：
const contentState = editorState.getCurrentContent();
const rawContent = convertToRaw(contentState);
window.localStorage.setItem(
"rawContent",
JSON.stringify(convertToRaw(rawContent))
);
然后，当我试图恢复它时，我正面临着我的问题。我认为qazxsw poi。
convertFromRaw我对此的临时解决方案是使用第三方转换器。在我的情况下，我使用了const rawContent = window.localStorage.getItem("rawContent");
if (rawContent) {
this.state.editorState = EditorState.createWithContent(
convertFromRaw(JSON.parse(rawContent))
);
} else {
this.state.editorState = EditorState.createEmpty();
}
的stateToMarkdown / stateFromMarkdown
我的package.json
draft-js-export-markdown / draft-js-import-markdown您的代码通常看起来正确。但正如我可以看到你使用{

两次。
convertToRaw尝试将const contentState = editorState.getCurrentContent();
const rawContent = convertToRaw(contentState); // <== convert to raw first time
window.localStorage.setItem(
"rawContent",
JSON.stringify(convertToRaw(rawContent)) // <== convert to raw again
);
重写为JSON.stringify(convertToRaw(rawContent))，我认为它应该可以解决您的问题。
如果这没有帮助你可以检查这个jsFiddle，它显示了Draft.js如何与本地存储一起使用的常见模式 - JSON.stringify(rawContent)
在本演示中，您可以看到简单的编辑器组件，当您单击https://jsfiddle.net/x2gsp6ju/4/时，我们将当前编辑器内容保存为本地存储的字符串。我们使用SAVE RAW CONTENT TO LOCAL STORAGE和convertToRaw：
JSON.stringify如果之后您重新加载页面，您的编辑器将使用您保存的内容和样式进行初始化。在 saveRaw = () => {
var contentRaw = convertToRaw(this.state.editorState.getCurrentContent());
localStorage.setItem('draftRaw', JSON.stringify(contentRaw));
}
中我们读了相应的本地存储属性，并使用constructor，JSON.parse和convertFromRaw方法初始化编辑器以及之前存储的内容。
