--description--
现在学习用 jQuery 从页面移除 HTML 标签。
jQuery 有一个 .remove()
方法,能完全移除 HTML 标签。
用 .remove()
方法从页面移除 target4
标签。
--hints--
应该用 jQuery 从页面中移除 target4
标签。
assert(
$('#target4').length === 0 && code.match(/\$\(["']#target4["']\).remove\(\)/g)
);
应该仅用 jQuery 移除该标签。
assert(
code.match(/id="target4/g) &&
!code.match(/<!--.*id="target4".*-->/g) &&
$('#right-well').length > 0
);
