Q: Why isn't the "World_day" map displayed when this service is normally accessed through the httpxmlrequest object of Javascript?

A: If there are Chinese characters in the url, they must be encoded, e.g., varmapName= encode URI (“WorldMap_day”). An encoded url is varuri = " http :// 192 .168 .115 .68:8 090/ iserver / services/ maps/rest/maps/"+mapName+".json".
