怎么将location.hostname，cmdport，dataport，loginuser，loginpass传进去呢？
- JScript code
function body_onload(){ var count; var port; if (location.port=='') port=80; else port=location.port; cameras.set_params(0,top.alias,location.hostname,cmdport,dataport,loginuser,loginpass); cameras.set_params(1,dev2_alias,dev2_host,dev2_cmdport,dev2_dataport,dev2_user,dev2_pwd); cameras.set_params(2,dev3_alias,dev3_host,dev3_cmdport,dev3_dataport,dev3_user,dev3_pwd); cameras.set_params(3,dev4_alias,dev4_host,dev4_cmdport,dev4_dataport,dev4_user,dev4_pwd); cameras.set_params(4,dev5_alias,dev5_host,dev5_cmdport,dev5_dataport,dev5_user,dev5_pwd); cameras.set_params(5,dev6_alias,dev6_host,dev6_cmdport,dev6_dataport,dev6_user,dev6_pwd); cameras.set_params(6,dev7_alias,dev7_host,dev7_cmdport,dev7_dataport,dev7_user,dev7_pwd); cameras.set_params(7,dev8_alias,dev8_host,dev8_cmdport,dev8_dataport,dev8_user,dev8_pwd); cameras.set_params(8,dev9_alias,dev9_host,dev9_cmdport,dev9_dataport,dev9_user,dev9_pwd); for (i=0;i<9;++i) { video[i].MonitorStatus = 0; video[i].SetDeviceName(cameras.alias[i]); cameras.PresetExcute[i]=true; cameras.PresetScript[i] = top.getcookie('PresetScript' + i ); if (record_osd) video[i].RecordOSD=true; cameras.pri[i]=PRI_REFUSE; cameras.retry_times[i]=0; cameras.restart[i]=0; cameras.alarm[i]=0; cameras.alarm_light[i]=0; cameras.width[i]=0; cameras.height[i]=0; if (cameras.host[i]!='') { device_status.src="images/yellow.gif"; connect_camera(i); } else device_status.src="images/gray.gif"; } nsplit=getcookie("split"); if(nsplit !=1 && nsplit!=4 && nsplit != 9) nsplit=1; x_onclick(nsplit,false); cameras.set_count(current,nsplit); current=0; if(cameras.count==1) alias_span.innerText = ""; else alias_span.innerText=cameras.alias[0]; document.getElementById('curpos').innerText = ptz_patrol_up_rate/2; ipcam_OnFocus(0);}<body onLoad="body_onload()" onUnload="body_onunload()" onContextMenu="return false">在页面加载启动时，有一个body_onload()方法，里面需要输入几个参数值，怎么将location.hostname，cmdport，dataport，loginuser，loginpass传进去呢？从后台查询数据库后传进去。[解决办法]
可以调用web service 解决。类似
- JScript code
return $.ajax({ type: "POST", url: "***.svc/GetParameters", data: '{"aaa" : "bbb"}', //传给web method的参数，可选 contentType: "application/json;charset=utf-8", dataType: "json", async: false, //同步调用 success: function (response) { //取得数据 }, error: function (response) { //报错。 } });

另外onload的解释:
The onload event occurs immediately after a page is loaded.
来自:

这个时候html已经载入完毕，控件应该都有值了，可以把值放在HiddenField控件， 在js中取值。

我想已经有答案了

用js post
var strUrl += "?hostname=location.hostname";
strUrl += "&cmdport=cmdport";
strUrl += "&dataport=dataport";
strUrl += "&loginuser=loginuser";
strUrl += "&loginpass=loginpass";
if(window.ActiveXObject)
{
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
else if(window.XMLHttpRequest)
{
xmlHttp = new XMLHttpRequest();
}
xmlHttp.open("POST", "xxxx.aspx", false);
xmlHttp.setRequestHeader("CONTENT-TYPE", "application/x-www-form-urlencoded;charset=utf-8");
xmlHttp.onreadystatechange = DGD01G1_HandleStateChange;
xmlHttp.send(strUrl);
