实现代码一：
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});
};

<script type="text/javascript">
var sa = '<a href=index.html>hello </a><input onlick=a(); typle="submit"/><input onlick=a(); value=ok typle="submit"/><span>a=8+4</span>';
var sb = document.getElementById('t').value;
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});
};
alert(addDqmForPP(sa));
alert(addDqmForPP(sb));
</script>
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;
});
};
