How to set default checkbox status with javascript?
提问by Astronaut
I am used to doing this in jQuery
我习惯于在 jQuery 中这样做
$('#RememberMe').attr('checked', true);
but I can't remember how to do it in Javascript I thought that
但我不记得如何在 Javascript 中做到这一点,我认为
document.getElementById("RememberMe").value = "True";
would work, but it doesn't, it changes the value but does not create the visual check on the html.
会工作,但它不会,它会更改值但不会在 html 上创建视觉检查。
