Details
This package contains:
- NgxScvUtil which contains following methods:
- deepCopy() - This method can be used to do a deep copy of an object. Internally it stringfys to JSON string and converts it back to an object so that a completely new object is obtained. None of the methods will be retained.
- extractTextFromHtml() - This method can be used to extract text from a string containing html. Ex: Passing "hello world" to this method will return "hello world".
- isNullOrEmpty() - This method will take a string, array or an object and return true under following conditions:
- If the argument passed is null or undefined
- If the argument is an array and the length is zero
- If the argument is an object with no fields
