How to hide "display:none" in html tag on a Visualforce Page Component?

I have made as per your suggestion but still it is not working

<apex:page standardcontroller=”Event” extensions=”ContentController” sidebar=”False” showHeader=”False”>

<apex:form >

<apex:pageBlock >
<apex:inputTextarea rows="10" cols="177" richText="True" value="{!Event.Description}" onChange="numCheck();" id="UploadImage" />
<script type="text/JavaScript">
function numCheck()
{
alert(document.getElementById("UploadImage").style.display = "block");
}
</script>

<apex:commandButton value="Save" action="{!save}" />

</apex:pageBlock>
<apex:inputFile value="{!file}" />
<apex:commandbutton action="{!upload}" value="Upload" />
</apex:form>
</apex:page>

public class ContentController {
public SObject record {get; private set;}
public ContentController() {

}

public Event myStandardObject;
public ContentController(ApexPages.StandardController controller) {
myStandardObject = (Event)controller.getRecord();
record = (Event)controller.getRecord();
}

public blob file { get; set; }

public PageReference upload() {
// String encodedContentsString = System.currentPageReference().getParameters().get('fileContents');
ContentVersion v = new ContentVersion();
v.versionData = file;
v.title = 'testing upload';
v.pathOnClient ='/somepath.txt';
insert v;
Event thisMatter = [select id from event where Id = :ApexPages.currentPage().getParameters().get('id')];
ContentVersion contentVersion_2 = [SELECT Id, Title, ContentDocumentId FROM ContentVersion WHERE Id = :v.Id LIMIT 1];
List<ContentDocument> documents = [SELECT Id, Title, LatestPublishedVersionId FROM ContentDocument];

ContentDocumentLink contentlink = new ContentDocumentLink();
contentlink.LinkedEntityId = thisMatter.id;
contentlink.contentdocumentid = contentVersion_2.contentdocumentid;
contentlink.ShareType = 'V';
insert contentlink;

// myStandardObject.id=v.id;
// insert myStandardObject;
return new PageReference('/' + thisMatter.id);
}
}
