Handling single quote in apex class

By using String.escapeSingleQuotes() method we handle single quotes in a string to inject query  as shown below

Eg:
==
squery='select id,name,Project_Number__c,Description__c,Project_Manager__c,Project_Director__c,Project_Manager__r.name,Project_Director__r.name from Milestone1_Project__c where ((name like\''+String.escapeSingleQuotes(searchString)+'%\' OR Project_Number__c like\''+String.escapeSingleQuotes(searchString)+'%\'))';

Handle single quotes within query in javascript

We are facing the problem with single quote characters in string query with filters.When single quotes are inluded in strings (either in filter conditions or searchstring) used in query we handle with replace function as shown below.
Eg: 


var projname=document.getElementById('pg:myForm:pb:newrecord:'+Rowindex+':pInput').value;
Here 'projname' is string with single quotes.
now  we want to use this in query as shown below

sforce.connection.sessionId = '{!$Api.Session_ID}';
 var result = sforce.connection.query("Select Id,Name From Milestone1_Project__c where name ="+"'"+projname.replace("\'","\\'")+"'");
 var records = result.getArray("records");

To retrieve values
if(records.length!=0){
            for(var i=0;i<records.length;i++){
                          alert(records[i].name); 
            }
}
