这种错误一般都是编码格式引起的
处理方法：分别打开你的js和aspx文件，然后菜单file-->Advanced Save Options-->选择Unicode (UTF-8 with signature)-Codepage 65001,然后确定，保存就可以了

不错啊！！！！！！！！！
永远支持楼主，多多发表一些技术性文章！！！！！！！！！！
回复

# re: 国家,省/州,城市下拉框 2005-12-29 16:53 jason_18

在ASP.NET好像不可以啊！！
但是在静态的可以，是不是还要再引用什么，还是加什么语句呢？？
总是提示错误:缺少")"，而且下面已经定义的变量，它也没说定义！！！！！！
用静态的直接就可以了，我测试了很久都不行，是不是在ASP.NET不行呢？
望楼主看到消息，能给个回复？？？？？？？？回复

# re: 国家,省/州,城市下拉框 2005-12-29 17:49 小山

参考上面的“错误脚本处理” 回复

# re: 国家,省/州,城市下拉框 2005-12-30 08:40 jason_18

按照您代码错误处理的方法，把它改作像您那样的话，它运行的时候不会提示有错误，但它什么也没显示了，查看代码，中文都变成了乱码，听说ASP.NET，和一些静态的用法不一样，会不会那些用法不一样导致的呢？
您能不能也做个ASP.NET的，把它里面代码一些该改的给改一下，那后再上传一下，好吗？回复

# re: 国家,省/州,城市下拉框 2005-12-30 08:54 jason_18

在Dreamweaver MX 调试运行的时候，是可以出来，但在.NET环境下，它就一直提示缺少缺少")"，和一些定义的变量，而且在调试的，代码都没变，而且都是在IE上调试，然道在.NET中还有什么特别限制吗？
什么原因会导致一个行，一个不行呢？
希望楼主能给我解释一下？回复

# re: 国家,省/州,城市下拉框 2005-12-30 08:56 小山

<globalization

responseEncoding="utf-8"

<httpHandlers> 回复

# re: 国家,省/州,城市下拉框 2005-12-30 09:49 jason_18

像这样的话，它就会提示:
分析器错误信息: 行“98”上的“httpHandlers”开始标记与文件“file:///c:/inetpub/wwwroot/城市下拉/web.config”中的结束标记“system.web”不匹配。行 99，位置 4。

源错误:

行 97： />
行 98： <httpHandlers>
行 99： </system.web>
行 100：
行 101：</configuration>
还是要加在什么地方呢？？？？？？？？？？

# re: 国家,省/州,城市下拉框 2005-12-30 11:05 jason_18

小山老师，能不能您用ASP.NET做一下，也上传上来呢？
后缀让它是.aspx，不是HTML！而且在.NET环境中可以运行出效果来呢？
一直想弄清楚，浪费了快一天时间呢？
有时间的话，能不能做个上传上来呢？回复

# re: 国家,省/州,城市下拉框 2005-12-30 13:17 小山

已提供，其实把html代码copy到aspx页面中，然后js文件和aspx文件都按照上面的错误处理方法处理，就ok了。回复

三 xmlhttp调用webservices

使用微软提供的webservice.htc实现通过JavaScript调用WebService.
1.首先从微软网站上下载webservice.htc,我附件源代码也包含，不下载也可以
http://msdn.microsoft.com/workshop/author/webservice/webservice.htc
2.在网页BODY中添加一个DIV，实现对webservice.htc的引用5.建立测试页面

drop table [ dbo ] . [ area ]

) ON [ PRIMARY ]

8.下载真实数据 /Files/singlepine/area.rar
9.源代码下载 /Files/singlepine/jsWebServices.rar

3.编写JavaScript，实现对WebService的引用：

function window_onload()

{

service.useService("/Service1.asmx?WSDL","myselect");

str_province=service.myselect.callService(province_Result,"getProvince");

}

useService 语法:
sElementID.useService(sWebServiceURL, sFriendlyName [, oUseOptions] )
useService 参数:

sElementID

Required. The id of the element to which the WebService behavior is attached.

sWebServiceURL

Required. String specifying the URL of the Web Service, using one of the following path types. See the examples section, where several variations of this parameter are shown.

Web Service file name	A Web service file, which has an .asmx file extension. This short form of the URL is sufficient, provided that the Web service is located in the same folder as the Web page using the WebService behavior. In this case, the ?WSDL query string is assumed by the behavior.
WSDL file name	A Web Services Description Language (WSDL) file name. The WSDL file must have a .wsdl file extension.
Full file path	Full path to a WebService (.asmx) or WSDL (.wsdl) file. A file path to a Web Service must include the ?WSDL query string. Either a local file path or a URL can be specified.
Relative path	A relative path to a WebService (.asmx) or WSDL (.wsdl) file. A file path to a Web Service must include the ?WSDL query string.

sFriendlyName

Required. String representing a friendly name for the Web Service URL.

oUseOptions

Optional. An instance of the useOptions object.

callService语法:
iCallID = sElementID.sFriendlyName.callService( [oCallHandler], fo, oParam )
callService参数:

sElementID

Required. The id of the element to which the WebService behavior is attached.

sFriendlyName

Required. The friendly name for the Web Service, which is defined by calling the useService method.

oCallHandler

Optional. Name of a script callback function that handles the results returned from this instance of the method call.

Required. One of the following possible values.

strFuncName	A String representing the name of the remote function being called. The String must be bounded by single or double quotation marks.
objCall	A call object, which has the necessary properties defined to call a remote function.

oParam

Required. One or more comma-delimited parameters, which are passed to the method name specified by fo.

4.建立WebService，代码如下

public class Service1 : System.Web.Services.WebService

{

public static string ConnectionString=System.Configuration.ConfigurationSettings.AppSettings["ConnectionString"];

SqlConnection conn=new SqlConnection(ConnectionString);

public Service1()

{

//CODEGEN: This call is required by the ASP.NET Web Services Designer

DropDownList既能选择又能输入

< html >

< head >

< style >

<!--

.cls1 { position:absolute; left:250px; top:89px; width:216px; height:72px; z-index:1; }

.cls2 { position:absolute; left:250px; top:89px; width:95px; height:18px; z-index:2 }

input { font-size: 12px; padding-top: 2px; padding-left: 2px;width:127;}

//-->

</ style >

</ head >

< script >

<!--

function addOption(pos){

if(event.keyCode==13)

{

var select_obj = document.getElementById("myselect");

var text_value = document.getElementById("test").value;

if (select_obj.length)

{

for (var i=0;i<select_obj.length;i++)

{

// 如果已经存在，不添加，直接退出

if (select_obj.options[i].text==text_value)

alert("选项已存在，请重新输入");

}

var the_option= new Option(text_value,text_value);

select_obj.add(the_option);

select_obj.selectedIndex = select_obj.options.length-1

}

//-->

</ script >

< div class ="cls1" style ="clip: rect(3 280 21 110)" >

按回车后如果输入地数字已经在下拉框中存在，它会弹出提示框说已经存在，但同时也会继续插入相同的数字，希望能够改进。
