Jquery addClass and Remove Class on hover

Question

好的，当鼠标悬停在元素#searchput时，我想向元素#searchput添加类cfse_a ，然后当鼠标悬停在元素上时，将类cfse_a删除。

Answer 1

Use hover event with addClass and removeClass methods:

$("#searchput").hover(function() {
    $(this).addClass("cfse_a");
}, function() {
    $(this).removeClass("cfse_a");
});

Answer 2

$('#searchput').hover(function() {
  $(this).addClass('cfse_a'); // add class when mouseover happen
}, function() {
  $(this).removeClass('cfse_a'); // remove class when mouseout happen
});

You can also use:

$('#searchput').hover(function() {
  $(this).toggleClass('cfse_a');
});

see toggleClass()
