秘银:不能 m.redraw 和 m.render
Mithril: cannot m.redraw with m.render
我有一个应用程序,我想在其中控制何时重绘视图。
我可以使用 m.mount
和 m.redraw
:
var count = 0;
var Counter = {
view: function() {
return m('main', [
m('h1', ('Count: ' + count))
])
}
}
m.mount(document.body, Counter);
window.setInterval(function () {
count++;
m.redraw();
}, 200);
<html>
<body>
<script src="https://unpkg.com/mithril/mithril.js"></script>
<script src="index.js"></script>
</body>
</html>
但是如果我使用 m.render
(因为我不需要秘银来自动重绘)它就不再有效了:
var count = 0;
var Counter = {
view: function() {
return m('main', [
m('h1', ('Count: ' + count))
])
}
}
m.render(document.body, m(Counter)); // <-- The only changed line
window.setInterval(function () {
count++;
m.redraw();
}, 200);

当使用 m.render
而不是 m.mount
时,如何重绘秘银?
如秘银文档中here所述:
Note that m.redraw
only works if you used m.mount
or m.route
. If you rendered via m.render
, you should use m.render
to redraw.
var count = 0;
var Counter = {
view: function() {
return m('main', [
m('h1', ('Count: ' + count))
])
}
}
m.render(document.body, m(Counter));
window.setInterval(function () {
count++;
m.render(document.body, m(Counter)); // <-- Use m.render here, not m.redraw
}, 200);
