[deprecated in 6.9] bool QJSValue:: isVariant () const

This function is deprecated since 6.9. We strongly advise against using it in new code.

返迴 true，若此 QJSValue is a variant value; otherwise returns false.

警告： This function is likely to give unexpected results. A variant value is only constructed by the QJSEngine in a very limited number of cases. This used to be different before Qt 5.14, where QJSEngine::toScriptValue would have created them for more types instead of corresponding ECMAScript types. You can get a valid QVariant 憑藉 toVariant for many values for which isVariant returns false.
