jQuery鼠标点击计数器

Question

I need to color a table in zebra style, and then when I click on the table, twice (not double click), it should change back to original.

My question is, how to count 2 clicks?

Answer 1

Demo: http://jsfiddle.net/aztVY/

(function () {
  var count = 0;

  $('table').click(function () {
    count += 1;

    if (count == 2) {
      // come code
    }
  });
})();

Answer 2

You can use jQuery's toggleClass function for that:

$(" ... ").click(function() {
    $(this).toggleClass("someClass");
});

When clicked once, the element has the someClass class, and when clicked twice, the class is removed again.

Answer 3

I might be wrong, but in between the lines of your question I read that you actually ask about toggleClass() method documented here .

Add or remove one or more classes from each element in the set of matched elements, depending on either the class's presence or the value of the switch argument.
