if (parameter[
1].constructor !=
Array)

var values = parameter[

var results = [];

'=' +
encodeURIComponent(values[i]));

}
}
function serializeForm(formId) {
var elements = getElements(formId);
var queryComponents =
new Array();
for (
var i =
0; i < elements.length; i++) {
var queryComponent = serializeElement(elements[i]);
if (queryComponent) {
queryComponents.push(queryComponent);
}
}
return queryComponents.join(
'&');
}
最后通过serializeForm(formId);输入form的id名称即可实现，返回数据为
id=
1&title=
