将变量中指定的CSS属性以外的属性赋予样式。

方法一：使用基本的CSS语法和JavaScript

const styleFromVariable = {
  background: "red",
  color: "white",
  fontSize: "20px",
  padding: "10px"
};

const exceptFor = ["background", "fontSize"];

const element = document.getElementById("myElement");

for (let prop in styleFromVariable) {
  if (!exceptFor.includes(prop)) {
    element.style[prop] = styleFromVariable[prop];
  }
}

方法二：使用Lodash库

const styleFromVariable = {
  background: "red",
  color: "white",
  fontSize: "20px",
  padding: "10px"
};

const exceptFor = ["background", "fontSize"];

const element = document.getElementById("myElement");

_.forEach(_.omit(styleFromVariable, exceptFor), (value, prop) => {
  element.style[prop] = value;
});
