I would like to get my code only concentrated on a few everytime. 我想让我的代码每次只专注于少数几个。
Instead of all of them, who could help me? 除了所有人,谁能帮助我?
<input id="01" type="radio">
<input id="02" type="radio">
<input id="03" type="radio">
<input id="04" type="radio">
<input id="05" type="radio">
<input id="06" type="radio">
var btn = document.getElementById("02");
setInterval(function() {
var list=document.getElementsByTagName("input");
for (i=0;i<list.length;i++) {
btn = list[i];
btn.checked == false ? btn.setAttribute("checked", "checked") : btn.removeAttribute("checked");
}
}, 500);
Here's the JsFiddle: http://jsfiddle.net/8sbt5oua/10/ 这是JsFiddle: http : //jsfiddle.net/8sbt5oua/10/
First have two arrays that you want to flicker on and off. 首先有两个要闪烁的数组。
var arr1 = [0,1,2];
var arr2 = [3,4,5];
You also want a global variable that toggles between the two. 您还需要一个在两者之间切换的全局变量。
var use_first = true;
Then you want to use the toggling variable to determine which one toggles on and which ones toggles off. 然后,您要使用切换变量来确定哪个打开和关闭。
let remove;
let checked;
if (use_first)
{
checked = arr1;
remove = arr2;
}
else
{
checked = arr2;
remove = arr1;
}
And I think the foreach explains themselves since they're basically your code. 而且我认为foreach可以自我解释,因为它们基本上就是您的代码。
Edit: 编辑:
remove.forEach(function(item, index)
{
btn = list[item];
btn.removeAttribute("checked");
});
checked.forEach(function(item, index)
{
btn=list[item];
btn.setAttribute("checked", "checked");
});
