$('input.ugd_ele_normal').on({
mouseenter: function() {
$(this).parent().css('background', 'url(/folder/image1.jpg)');
},
mouseleave: function() {
$(this).parent().css('background', 'url(/folder/image2.jpg)');
}
});
或短(ER)版本:
$('input.ugd_ele_normal').on('mouseenter mouseleave', function(e) {
$(this).parent()
.css('background-color', e.type=='mouseenter'?'url(/folder/image1.jpg)':'url(/folder/image2.jpg)');
});
并检索旧图像:
var bgImg = $('input.ugd_ele_normal').css('background-image'),
hvImg = 'url(/folder/image2.jpg)';
$('input.ugd_ele_normal').on('mouseenter mouseleave', function(e) {
$(this).parent()
.css('background-image', e.type=='mouseenter'?hvImg:bgImg);
});
或使用类:
.hoverClass {background: url(/folder/image2.jpg);}
-
$('input.ugd_ele_normal').on('mouseenter mouseleave', function() {
$(this).toggleClass('hoverClass');
});
