ajax修改表单的值后dom没更新的解决办法

添加一个扩展方法，通过$("#id").html($("#id").formhtml())更改。

扩展方法：

(function ($) {
var oldHTML = $.fn.html;
$.fn.formhtml = function () {
if (arguments.length) return oldHTML.apply(this, arguments);
$("input,textarea,button", this).each(function () {
this.setAttribute('value', this.value);
});
$(":radio,:checkbox", this).each(function () {
// im not really even sure you need to do this for "checked"
// but what the heck, better safe than sorry
if (this.checked) this.setAttribute('checked', 'checked');
else this.removeAttribute('checked');
});
$("option", this).each(function () {
// also not sure, but, better safe...
if (this.selected) this.setAttribute('selected', 'selected');
else this.removeAttribute('selected');
});
return oldHTML.apply(this);
};
//optional to override real .html() if you want
// $.fn.html = $.fn.formhtml;
})(jQuery);
