How can I change css styles with javaScript by date condition?

Question

I was wonder if anyone can tell me why this isn't working? I am trying to switch display of div.

function testDatum(){
    var vandaag = new Date();
    var eindDatum = new Date('04/15/2018');
    if (vandaag > eindDatum){
        document.getElementById('Div1').style.display = 'none';
    } 
    else {
        document.getElementById('Div2').style.display = 'none';
    }   
}

Answer 1

The code works....

 function testDatum(){ var vandaag = new Date(); var eindDatum = new Date('05/15/2018'); if (vandaag > eindDatum){ document.getElementById('Div1').style.display = 'none'; } else { document.getElementById('Div2').style.display = 'none'; } } testDatum() 

 <div id="Div1">Div1</div> <div id="Div2">Div2</div> 

Answer 2

What you have written, It's absolute current but you didn't declare the function. So, You didn't get any result.

declare function now you get result. testDatum();
