jquery AJAX传MAP类型的参数，中文问题

是用jquery的AJAX来发送异步请求，是用MAP类型来传递参数，遇到中文的时候是乱码，具体代码如下

var dbUser =  document.getElementById("dbUser").value;var schemaObject =  document.getElementById("schemaObject").value;var appName =  document.getElementById("appName").value;var ipAddress =  document.getElementById("ipAddress").value;var timestamp =  document.getElementById("timestamp").value;var auditLevel =  document.getElementById("auditLevel").value;var dbId =  document.getElementById("dbId").value;var sqlText=document.getElementById("sqlText").value;var map = "sqlText="+sqlText+"&dbUser=" + dbUser+"&tmpName="+tmpName+"&mail="+mail+"&schemaObject=" + schemaObject + "&appName=" + appName+ "&ipAddress="+ipAddress+"&timestamp="+timestamp+"&timestamp="+timestamp+"&dbId="+dbId+"&auditLevel="+auditLevel; $.ajax({type:"POST",url:"<c:url value='/accessaudits/saveSearch.do'/>",data:map,async:false,success:function(data){var infos = eval("(" + data + ")");alert(infos["info"]);}});

?

var map = "sqlText="+sqlText+"&dbUser=" + dbUser+"&tmpName="+tmpName+"&mail="+mail+"&schemaObject=" + schemaObject + "&appName=" + appName+ "&ipAddress="+ipAddress+"&timestamp="+timestamp+"&timestamp="+timestamp+"&dbId="+dbId+"&auditLevel="+auditLevel;

? 假如sqlText有中文，那么采用data:map传参就有乱码。

?

? 办法是用escape关键字解决问题

var map = "sqlText="+escape(sqlText)+"&dbUser=" + dbUser+"&tmpName="+tmpName+"&mail="+mail+"&schemaObject=" + schemaObject + "&appName=" + appName+ "&ipAddress="+ipAddress+"&timestamp="+timestamp+"&timestamp="+timestamp+"&dbId="+dbId+"&auditLevel="+auditLevel;
