The method of realizing full angle turning half angle with javascript _javascript technique

In this paper, we illustrate the method of JavaScript to realize full angle turning half angle. Share to everyone for your reference, specific as follows:

function Fullchar2halfchar (str)
{
 var result = ';
 for (i=0; i<str.length; i++)
 {
 code = str.charcodeat (i);//Get the Unicode encoding of the current character
 if (code >= 65281 && Amp Code <= 65373//In this Unicode encoding range is all the English letters have been various characters
 {result
  + + string.fromcharcode (str.charcodeat (i)-65248) ;//Convert Unicode encoding of full-width characters to the corresponding Half-width character Unicode code
 }else if (code = = 12288)/space
 {result
  + = String.fromCharCode ( Str.charcodeat (i)-12288 +);
 } else
 {Result
  = Str.charat (i);
 }
 }
 return result;
}

I hope this article will help you with JavaScript programming.
