mootools将表单变成json格式(二)

Element.extend({
toJsonString:function(){
var queryString = [];
this.getFormElements().each(function(el){
var name = el.name;
var value = el.getValue();
if (value === false || !name || el.disabled) return;
var qs = function(val){
queryString.push('"' + name.replace(/(["\\])/g, '\\$1') + '":"' + val.replace(/(["\\])/g, '\\$1') + '"');
};
if ($type(value) == 'array') value.each(qs);
else qs(value);
});
return '{' + queryString.join(',') + '}';
}
});
