Through the use of actionFunction with <apex:param/> you can pass value to the controler:

You can pass value as "{!Account.Name}" in the javascript method.

<script type="text/javascript">
      function displayFunc(value)
      {
           passValueToController(encodeURIComponent(value));
      }        
</script>
<apex:actionFunction name="passValueToController" action="{!passValue}" immediate="true" reRender="form1">
     <apex:param id="selectedValue" name="selectedValue" value=""/> 
</apex:actionFunction>

public void passValue()
{
      fieldValue = ApexPages.currentPage().getParameters().get('selectedValue');
      System.debug('fieldValue=' + fieldValue);     
}
