JavaScript例子：函数中的arguments对象

arguments is an array-like object accessible inside functions that contains the values of the arguments passed to that function.

function func1(a, b, c) {

console.log(arguments[0]);

// Expected output: 1

console.log(arguments[1]);

// Expected output: 2

console.log(arguments[2]);

// Expected output: 3

}

func1(1, 2, 3);

Attribute selectors

The CSS attribute selector matches elements based on the presence or value of a given attribute.

/* <a> elements with a title attribute */
a[title] {
  color: purple;
}

/* <a> elements with an href matching "https://example.org" */
a[href="https://example.org"]
{
  color: green;
}

/* <a> elements with an href containing "example" */
a[href*="example"] {
  font-size: 2em;
}

/* <a> elements with an href ending ".org" */
a[href$=".org"] {
  font-style: italic;
}

/* <a> elements whose class attribute contains the word "logo" */
a[class~="logo"] {
  padding: 2px;
}
