    Hello prati@salesforce,

    In addition to soni piyush's solution:

    Hardcode element's Id in your javascript code it is not recommended. So, a different scenario using the code above would be passing the element Id

    as a parameter. By doing so, you are allowing your code to be reused as many times as you want in your Visualforce page. Please, consider the code below:

    <apex:page standardController="Account">

    <script>

        function changeCase(elId){

            var x = document.getElementById(elId);

            x.value = x.value.toUpperCase();

        }

    </script>

    <apex:form>

        <apex:inputField value="{!account.Name}" id="id1" onchange="changeCase('{!$Component.id1}');"/>

    </apex:form> 

    </apex:page>

    Note that using the global merge field type $Component will allow you to get element's full Id. Consider reading the following dev guide:

    https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_variables_global_component.htm

    Regards.
