javascript

js操作字符串时，如果字符串中存在换行符"\n”时会出现错误，下面给出解决办法。

js端解决办法：
function getzfc(str)
{
if(str != null){
str = str=str.replace(/^\n+|\n+$/g,"<br />");
}
return str;
}

java端解决办法：
public static String MyReplace(String mystr)
    {
if(mystr != null)
{
         mystr = mystr.replace("\r\n", "<br/>");
          mystr = mystr.replace("'", "&nbsp;");
         mystr = mystr.replace("\r", "<br/>");
         mystr = mystr.replace("\n", "<br/>");
         mystr = mystr.replace("\t", "&nbsp;&nbsp;&nbsp;&nbsp;");
         mystr = mystr.replace(" ", "&nbsp;");
        //mystr = mystr.Replace("<","&lt;");
        //mystr = mystr.Replace(">","&gt;");
        //mystr = mystr.Replace("&","&amp");
}
        return mystr;

    }
