I need to dynamically generate some bottoms based on the return of ajax get call 

@.getJSON("SearchByName", {"name":searchstring}, function(data){
    data = data.replace(/ /g, "&nbsp");
    var pop = "<p>" + data + "</p><br/><button style=\"border-radius: 
    4px;\" onclick=getDatabyName(\"" + data +"\")>Load 
    Locations</button>";
    .....

Since the return data may have space so I have to replace all spaces with &nbsp;

When users press the generated bottom to execute getDatabyName, it calls a Servlet to query a database. However, the query within the Java Servlet returns nothing because the space characters are not properly encoded. I tried to do another replace inside getDatabyName but still the same. I have ways to work around this but want to know the proper ways (either in Javascript or in Java) to handle this situation.

See this post on how to fix your Java Servlet to decode HTML input:

PS. Change &nbsp to &nbsp; in your code.
