 How to call Apex method from VF page When Pressing of Enter Key.

 Hi,

In this example i am going to call apex method when ever user enters Account name in search box and press enter key.the following is the code example.

Visualforce page :
<apex:page standardController="account" extensions="searchaccounts">
   <apex:form >
         <script type='text/javascript'>
           function runOnEnter(ev)
           {
            if (window.event && window.event.keyCode == 13 || ev.which == 13)
              {
               searchAccRecs();
               return false;
              }
              else
              {
                return true;
              }
           }
</script>
<apex:pageBlock >
      <apex:inputText value="{!searchString}" onkeypress="return runOnEnter(event);"/>
         <apex:commandButton value="Submit" action="{!searchAcc}" reRender="pgblcktbl"/>
          <apex:pageBlockTable value="{!accList}" var="acc" id="pgblcktbl">
            <apex:column value="{!acc.name}"/>
            <apex:column value="{!acc.accountnumber}"/>
            <apex:column value="{!acc.annualrevenue}"/>
            <apex:column value="{!acc.Industry}"/>
            <apex:column value="{!acc.AccountSource }"/>
         </apex:pageBlockTable>
</apex:pageBlock>
<apex:actionFunction name="searchAccRecs" action="{!searchAcc}" reRender="pgblcktbl"/>
</apex:form>
</apex:page>

Extension controller :
public with sharing class searchaccounts {

       Public List<account> accList{get;set;}
       Public string searchString{get;set;}

          public searchaccounts(ApexPages.StandardController controller) {
     }
     Public void searchAcc()
     {
         accList = new List<account>();
         accList = [select id,name,accountnumber,annualrevenue,Industry,AccountSource from account where name =: searchString limit 5];
     }

}
