Hi sfdc,

Try this piece of code.
  
<apex:page >
 <apex:form id="formid">
 <apex:pageblock id="formid1">
 
 <apex:panelGrid columns="2">
 <apex:inputText id="theTextInput"/>

 <apex:commandButton value="Update" style="width:90px" onclick='popup()'/>
 </apex:panelGrid>
 </apex:pageblock>
 </apex:form>
 
 <script type="text/javascript">
 
 function popup(){
 var a=document.getElementById('{!$Component.formid.formid1.theTextInput}').value;
 
 if(a == '' || a == null)
 {
 alert('please enter a review first');
 }
 else{
 
 alert('Hello world');
 }
 
 }
 </script>
 
</apex:page>
