jquery 按钮效果 正常、移上、按下

在网页设计过程中,经常遇见按钮的各状态效果。写了一个jquery扩展,使这个过程更方便!

使用前注意引用Jquery;

JqueryExtend.js:

(function ($) {
// Button按钮的三种样式替换,如果isState参数为True则记录按下状态
    $.fn.btnEffect = function (normal, mouseover, mousedown, isState) {
        var lastButton;
        this.each(function () {
            $(this).bind({
                mouseover: function () {
                    if (this != lastButton || !isState) {
                        $(this).removeClass().addClass(mouseover)
                    }
                },
                mouseout: function () {
                    if (this != lastButton || !isState) {
                        $(this).removeClass().addClass(normal)
                    }
                },
                mousedown: function () {
                    if (this != lastButton || !isState) {
                        if (lastButton != null) {
                            $(lastButton).removeClass().addClass(normal);
                        }

                        $(this).removeClass().addClass(mousedown);
                        lastButton = this;
                    }
                }
            });
        });
    }
})(jQuery);
