如何将一个文本区里的内容中的空格，回车，换行字符去掉并统计出字数？

  1<str.length;i++) '求字符串的绝对字节数（汉字为两个字节）="" )="" \---------------------------------------------------------------="" continue;="" count="0" count,i="" dim="" function="" if="" if(str[i]=" " my_len(str)="" str<="" sum++;="" {="" }="" 用下面这个函数="">"" then   
  2for i=1 to len(str)   
  3if asc(mid(str,i,1))&lt;0 then   
  4count=count+2   
  5else   
  6count=count+1   
  7end if   
  8next   
  9end if   
 10my_len=count   
 11end function   
 12  
 13这个函数可应用在服务器端也可用在客户端，调用的时候这样   
 14  
 15总字数=my_len(str)   
 16里面的str就是你取到的文本框里面的内容，不用替换

 19<textarea name="a" style="width:50%;height:50%"></textarea><input onclick="geth(a)" type="button" value="get"/>
 20<script>   
 21function geth(o)   
 22{   
 23str=o.value.replace(/\s/g,'')   
 24alert(str)   
 25var tmp = 0;   
 26for(var i=0;i<str.length;i++)   
 27{   
 28if(str.charCodeAt(i)>255)   
 29tmp += 2   
 30else   
 31tmp += 1   
 32}   
 33alert(tmp)   
 34}   
 35  
 36</script>

 42  
 43function getStrLeng(byval str,byref length)   
 44str = replace(str,chr(13)&amp;chr(10),"")   
 45length = len(str)   
 46getStrLeng = str   
 47end function   
 48  
 49用法   
 50dim str,newStr,strLen   
 51newStr=getStrLeng(str,strLen)   
 52  
 53newStr就是替换后的str,strLen就是length

 55  
 56<form name="form1">
 57<textarea name="txt"></textarea>
 58<input onclick="mm()" type="button" value="ok"/>
 59</form>
 60<script language="javascript">   
 61function String.prototype.lenB(){return this.replace(/[^\x00-\xff]/g,"**").length;}   
 62function mm()   
 63{   
 64var s = document.form1.txt.value;   
 65s = s.replace(/\r\n/g, "").replace(/ /g, "");   
 66alert(s.lenB());   
 67}   
 68</script>

 71写错了，更正   
 72function getStrLeng(byval str,byref length)   
 73str = clearString(str)   
 74do while instr(1,str,chr(13)&amp;chr(10))&gt;0   
 75str = clearString(str)   
 76loop   
 77length = len(str)   
 78getStrLeng = str   
 79end function   
 80  
 81function clearString(str)   
 82clearString = replace(str,chr(13)&amp;chr(10),"")   
 83  
 84end function   
 85  
 86  
 87用法   
 88dim str,newStr,strLen   
 89newStr=getStrLeng(str,strLen)   
 90  
 91newStr就是替换后的str,strLen就是length

 93  
 94<textarea name="txt"></textarea>
 95<input onclick="count()" type="button" value="ok"/>
 96<script language="javascript">   
 97function String.prototype.lenB(){return this.replace(/[^\x00-\xff]/g,"**").length;}   
 98function count()   
 99{   
100var s =txt.value;   
101s = s.replace(/(\r\n ¦\s)/g, "")   
102alert(s.lenB());

110</form>   
111\---------------------------------------------------------------   
112  
113<form onsubmit="return check()">   
114  
115在check()中写form1.input1.value=document.form1.txt.value.replace(/\r\n/g, "").replace(/ /g, "").replace(/[^\x00-\xff]/g,"**").length)'</form></str.length;i++)>
