Hi,

Thanks for the answer. I want to display the default value. But in the code which u have sent, they are assigning the default value.

I have 5 values in my picklist 1,2,3,4,5---- while displaying to user 3 should be selected upon page load. if user clicks on dropdown he can still see 1,2,3,4,5

Thanks

I am doing like this --->

<apex:page controller="SetValue">
<script type='text/javascript'>
$( document ).ready(function() {
    $("#Default").val("3");    
    });
                
        </script>
    <apex:form >
    <br/>
        <apex:selectList size="1" title="Country" id="Default" >
            <apex:selectOptions value="{!items}"/>
     
    </apex:selectList>
    
    </apex:form>
</apex:page>

But value 3 is not getting preselected in Dropdown.

Please suggest

The easiest approach is to set this in your controller's constructor.  The idea is to use the value attribute on your select list, which will get and set a variable in your controller.  For example:

Your visualforce example would look like:

<apex:selectList size="1" title="Country" id="Default" value="{!selectedItem}">
    <apex:selectOptions value="{!items}"/>
</apex:selectList>


Your constructor might look like:

public String selectedItem {get; set;}

public MyController(){
    this.selectedItem = 'defaultValue';
}

Note that selectedItem would need to match the value of one of the select options in your items list.

Hi Ganesh,

I made some changes in your script.
As apex:selectlist will create a Dom Element Id.
If You want to use jquery/javascript to do then use this.

<apex:page controller="SetValue">
<script type='text/javascript'>
$( document ).ready(function() {
    $('select[id*="Default"]').val('3') ;
    });
                
        </script>
    <apex:form >
    <br/>
        <apex:selectList size="1" title="Country" id="Default" >
            <apex:selectOptions value="{!items}"/>
     
    </apex:selectList>
    
    </apex:form>
</apex:page>

Hi Dushyant -

I'm using your script on a Visualforce page that uses the standard controller for accounts - it is setting the value I want in the view dropdown, but the page isn't loading the content based on the selected view. Any suggestions? Thanks.
