jQuery creates a custom selector to select hyperlink instances with a height greater than 100_jquery

The example in this article describes how jQuery creates a custom selector to select hyperlinks with a height greater than 100. Share it with everyone for your reference. The specific analysis is as follows:

jQuery creates a custom selector. The selector you define can actually be a function. The following JS code defines an over100pixels selector to select links with a height greater than 100. This type of technique is very practical.

$.extend($.expr[':'], {
  over100pixels: function(a) {
    return $(a).height() > 100;
  }
});
$('.box:over100pixels').click(function() {
  alert('The element you clicked is over 100 pixels high');
});

I hope this article will be helpful to everyone’s jQuery programming.
