Use it to write down, get the string byte length, suitable for Chinese characters and English mixed input1 functiongetbytescount (str)2 {3 varBytescount = 0;4 if(str! =NULL)5 {6 for(vari = 0; i )7 {8 varc =Str.charat (i);9
There are a number of methods, two:
First: (Through the charCodeAt method of the string object)
