一些常用的JS代码
function execServlet(servletUrl,callStyle,str){var ret = "";
if(!callStyle) callStyle = "GET";
try {
xh = new ActiveXObject("Microsoft.XMLHTTP");
xh.open( callStyle,servletUrl,false);
xh.send(str);
ret = xh.responseText;
}catch (error){
}
return ret;
}
function changeCinema(obj){
var cinemaSelect=document.getElementById("cinemaNameSearch");
var rnd = Math.random();
var url="<%=contextPath%>/infoservice/filmScheduleAction.action?action=chanegCinema&&cityCodeSearch="+obj.value;
var ret=execServlet(url,'GET',"");
var str=ret.split("&&");
cinemaSelect.innerHTML="";
cinemaSelect.options.add(new Option("-请选择-",""));
for(var i=0;i<str.length&&""!=str;i++){
cinemaSelect.options.add(new Option(str,str));
}
}
