     var selectedCity = document.entryForm.entry.value
     for ( var i = 0; i < BigCities.length; i++) {
          if (BigCities[i] == selectedCity) {
          break
          }

放个容器，设置容器

<SCRIPT LANGUAGE="JavaScript">
var BigCities = new Array(4)
BigCities[0] = "hong"
BigCities[1] = "kong"
BigCities[2] = "New York"
BigCities[3] = "Los Angeles"
BigCities[4] = "Shanghai"


var Location = new Array(4)
Location [0] = "hk"
Location [1] = "mbc"
Location [2] = "USA"
Location [3] = "USA"
Location [4] = "China"


function getLocation() {

     var selectedCity = document.entryForm.entry.value
     for ( var i = 0; i < BigCities.length; i++) {
          if (BigCities[i] == selectedCity) {
          break
          }
     }
     document.getElementById('dv').innerHTML = "城市位于 " + Location[i] + ".";
}
</SCRIPT>
<FORM NAME="entryForm">
<INPUT TYPE="text" NAME="entry">
<INPUT TYPE="button" VALUE="城市所在" onClick="getLocation()">
    <div id="dv"></div>
</form>
