ff下js失效,帮看看怎么改一下?
省份和城市二级联动的菜单,在IE下可以,在FF下失效,错误报"CityObj has no properties"错误,行"var cityCount = cityObj.options.length;"[code]<script language="JavaScript" type="text/javascript">
var cityList;
var cityInitSelected = 0;
function InitCities(provinceObjId, cityObjId) {
var cityObj = document.getElementById(cityObjId);
var cityCount = cityObj.options.length;
var i = 0; j = 0;
var item;
var textArray;

item = cityObj.options[i];
if (item.text == "") continue;
j += 1;

cityList = new Array(j);
j = 0;
for (i = 0; i < cityCount; i ++) {
item = cityObj.options[i];

</select>[/code] 你的InitCities是这样的
function InitCities(provinceObjId, cityObjId) {
var cityObj = document.getElementById(cityObjId);
。。。。。。
}
调用入口是body的onload
<body onload="InitCities('ddlProvince', 'ddlCity')">
但是你的select元素id却不是ddlCity
<select name="ddlCity" id="select14" class="fontnormal">
问题就很明显了 谢谢,问题的确如此
