Check for Empty strings in Java Script

Below is the code for checking the Empty Strings present in the Java Script

string str;

if(str != ‘undefined’ && str != null && str != ” && str != undefined && str != ‘null’ && str != ‘ ‘ && str.trim() != ”)
{
// if string is not empty do your logic

}
else // if string is empty
{
do your logic
}

Using this we can check the empty strings in JavaScript.
