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);
