您可以使用DOM的setAttribute函数设置多个属性吗? [英] Can you set multiple attributes with the DOM's setAttribute function?

问题描述

比方说，我想使用DOM创建输入元素.而不是像这样

Let's say I wanted to create an input element using the DOM. Instead of doing something like this

var input = document.createElement("input");
input.setAttribute("class", "my-class");
input.setAttribute("type", "checkbox");
input.setAttribute("checked", "checked");

是否存在将这三行代码写成一行的DRYer方法.

Is there a DRYer way to write these three lines of code into one line.

我知道你可以做这样的事情

I know you could do something like this

var attributes = ["class", "type", "checked"];
var values = ["my-class", "checkbox", "checked"];

for (var i = 0; i < attributes.length; i++) {
  input.setAttribute(attributes[i], values[i])
end

问题是，只有在需要添加大量属性的情况下，该功能才有用.如果只有两个或三个，则DRY更少.

The problem is that is only helpful if you have a boatload of attributes you need to add. If you only have two or three, this is even less DRY.

反正我可以结束这段代码吗?

Is there anyway I can dry up this code?

推荐答案

是的，您可以使用Jquery.

Yes, You can do using Jquery.

$(input).attr(
{
  "data-test-1": num1, 
  "data-test-2": num2
});
