jquery - 从 jQuery 对象中删除 DOM 元素

Question

jQuery 可以轻松地从 DOM 中删除节点。但是如何从给定的 jQuery 对象中删除 DOM 元素呢？

Answer 1

如果您正在谈论从 jQuery 对象中删除节点，请使用 filter 或 not 函数。 See here for more .

如何使用过滤器:

var ps = $('p');

//Removes all elements from the set of matched elements that do 
//not match the specified function.
ps = ps.filter(function() {
  //return true to keep it, false to discard it
  //the logic is up to you.
});

或

var ps = $('p');

//Removes all elements from the set of matched elements that 
//do not match the specified expression(s).
ps = ps.filter('.selector');

如何使用not:

var ps = $('p');

//Removes elements matching the specified expression 
//from the set of matched elements.
ps = ps.not('.selector');
