js extracts an instance of a special string length

Examples are as follows:

// Extract the length of a special string (scrstr source string armstr special characters)getStrCount: function(scrstr, armstr) {
 var count = 0;
 while ((armstr) &gt;= 1) {
  scrstr = (armstr, "")
  count++;
 }
 return count;
}

The above example of extracting a special string length of a certain js () is all the content I share with you. I hope you can give you a reference and I hope you can support me more.
