javascript 用正则表达式进行转换处理
var HtmlUtil = {
/*1.用正则表达式实现html转码*/
htmlEncodeByRegExp:function (str){
var s = "";
if(str.length == 0) return "";
s = str.replace(/&/g,"&");
s = s.replace(/</g,"<");
s = s.replace(/>/g,">");
s = s.replace(/ /g," ");
s = s.replace(/\'/g,"'");
s = s.replace(/\"/g,""");
return s;
},
/*2.用正则表达式实现html解码*/
htmlDecodeByRegExp:function (str){
var s = "";
if(str.length == 0) return "";
s = str.replace(/&/g,"&");
s = s.replace(/</g,"<");
s = s.replace(/>/g,">");
s = s.replace(/ /g," ");
s = s.replace(/'/g,"\'");
s = s.replace(/"/g,"\"");
return s;
}
};
