jstree报错 Cannot read property ‘state’ of undefined
This error occurs when you are trying to read a property called "styles" from an undefined object. It means that the object you are trying to access does not exist or is not defined.
To fix this error, you need to make sure that the object you are trying to access exists and is defined. You can do this by checking if the object is null or undefined before trying to access its properties.
For example, if you have an object called "myObj" and you want to access its "styles" property, you can check if it exists like this:
if (myObj && myObj.styles) {
// Access the styles property here
}
This way, you will avoid the TypeError and your code will run without errors.
