I have to hide one web part on page or whole page (whatever I find quicker) on every Friday. I was sure javascript code will work, but it still shows web part.
window.addEventListener("load", function(){
var currentDay = new Date();
var day = currentDay.getDay();
var hideMe = document.getElementById("MSOZoneCell_WebPartWPQ3");
/* This is web part that I need to hide */
if(day=3) { /* I put 3 for today to check if it will work, but I need Friday as a day */
hideMe.style.display = "none";
}
else {
hideMe.style.display = "block";
}
}, false);
