如果语句什么都不做 javascript

Question

Okay so here's a simple question that I understood but got asked... let's say you have an if statement

if (window.location.href == 'http://' ||
    window.location.href == 'http://?pg=pgOldMainMenu' ||
    window.location.href == 'http://default.asp#') 

else {}

How can you say "if positive do nothing, else load this HTML"?

Answer 1

Simply like this

var href = window.location.href;

if (href == 'http://' ||
    href == 'http://?pg=pgOldMainMenu' ||
    href == 'http://default.asp#') {}   // do nothing
else {
    href = 'url you want to load';
}
