给标签内属性值加上双引号

var addDqmForPP = function(shtml){ return shtml.replace(/( [^\=]*\=)(\s?[^\"\s\>]*)/ig,function(a,b,c,d,e){return (c)?(new RegExp("<[^>]*"+c.replace(/(\^|\(|\)|\[|\]|\{|\}|\?|\-|\\|\/|\||\$)/g,'\\$1')+"[^>]*>","i").test(e))?b+'"'+c+'"':b+c:b}); };

实现代码二：

给标签内属性值加上双引号标记变小写

核心代码

var partialXHTML = function (value) { return value.replace(/<(\/?[a-zA-Z]+\s*)((?:"[^"]*"|'[^']*'|(?!'|"|\/?>).)*)(\/?>)/g, function (l, $1, $2, $3) { return '<' + $1.toLowerCase() + $2.replace(/([^=]+)=(?:(")[^"]*"|(')[^']*'|((?:(?!\s|'|"|\/?>).)*))/g, function (l, $1, $2, $3, $4) { return ($2||$3) ? l : $1 + '="' + $4 + '"'; }) + $3; }); };
