Sys.StringBuilder isEmpty Method

Determines whether the Sys.StringBuilder object has content.

var stringBuilderVar = new Sys.StringBuilder();
var isEmptyVar = stringBuilderVar.isEmpty();

Returns

true if the StringBuilder instance contains no elements; otherwise, false.

Remarks

Use the isEmpty method to determine whether a StringBuilder instance has any content. If you append an empty string, null, or an undefined value to an empty StringBuilder instance, the instance remains empty and unchanged.
