选择省得到市，现在能得到省，确得不到相应的市，
//得到所有市
$(document).ready(function () {
$.ajax({ url: "serverDoc.xml",
success: function (xml) {
$(xml).find("title").each(function () {
var t = $(this).text(); //this->
$("#DropProvince").append("<option>" + t + "</option>");
});
}
});
//得到所有市，有问题。。。
$("#DropProvince").change(function () {
$("#sCity>option").remove();
var pname = $("#DropProvince").val();
$.ajax({ url: "serverDoc.xml",
success: function (xml) {
alert($("#DropProvince").val().find("item city").text());
$(xml).find("province[val=" + pname + "] city").each(function () {
$("#sCity").append("<option>" + $(this).text() + "</option>");
});
}
});
});
});
<select id="DropProvince" style="width:60px;">
<option>请选择</option>
</select>
<select id="sCity" style="width:60px;">
</select>
