我刚刚尝试用 jquery 设置一些动画,获得一个漂亮的动画有点棘手。但是那个看起来还不错(DEMO)。
var expElem = $(".hover-spell");
var exp = expElem.text();
var run = false;
expElem.empty();
for(var i = 0; i <= exp.length; i++) {
expElem.append('<span>'+exp.charAt(i)+'</span>');
}
expElem.mouseover(function() {
if(run === true) return false;
run = true;
var stepDuration = 300;
var counter = 0;
(function anim(){
if(counter == exp.length -1) return false; //Remove -1 to get last "e" animated
counter++;
var nth = exp.length;
var elem = $('span:nth-child('+nth+')', expElem);
elem.slideUp(stepDuration, function() {
(function() {
if(counter == 1) return elem.prependTo(expElem);
else return elem.insertAfter($('span:nth-child('+(counter-1)+')', expElem));
})().slideDown(stepDuration, anim);
});
})();
});
让它与悬停(包括鼠标离开)一起工作有点复杂。您也可以尝试存储位置,然后将它们相互滑动,但又有点复杂。
