使用Symfony2和Twig的实时时钟Javascript

Question

i've been trying to do a live watch with javascript to be shown in a twig template, the issue is, it doesn't update automatically when the time changes, i don't know if it's my mistake or i'm not using javascript properly and it's possible it's a really dumb mistake or that i'm doing a rookie thing, so my apologies in advance. 我一直在尝试使用javascript进行实时监视，以显示在树枝模板中，问题是，时间变化时它不会自动更新，我不知道这是我的错还是我没有使用javascript正确，这可能是一个非常愚蠢的错误，或者我在做菜鸟，所以提前致歉。

Answer 1

The script doesn't work because the time is dumped only once whereas it should be dumped every second. 该脚本不起作用，因为时间仅转储一次，而时间应每秒转储一次。 To do it use javascript function setInterval : 为此，请使用javascript函数setInterval ：

var delay = 1000; // 1000 microseconds equal to 1 second

// setInterval executes passed function every second
setInterval(function() {
    // do time calculation and displaying
}, delay);
