这篇文章给大家分享的是有关jQuery如何实现炫丽的3d旋转星空效果的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
该特效也是在Jquery插件库中找到的，感觉效果不错，说不定以后项目中要有绚丽的星空背景，拿来即用，收藏了下。

<script>
$(document).ready(function () {

transform: ' translate3d(0,0,-' + curR + 'px) rotateY(' + Math.random() * 360 + 'deg) rotateX(' + Math.random() * -50 + 'deg) scale(' + s + ',' + s + ')'
});
});
});
</script>
</body>
</html>运行的效果如下：
其中stopExecutionOnTimeout.js如下：
"use strict";"object"!=typeof window.CP&&(window.CP={}),window.CP.PenTimer={programNoLongerBeingMonitored:!1,timeOfFirstCallToShouldStopLoop:0,_loopExits:{},_loopTimers:{},START_MONITORING_AFTER:2e3,STOP_ALL_MONITORING_TIMEOUT:5e3,MAX_TIME_IN_LOOP_WO_EXIT:2200,exitedLoop:function(o){this._loopExits[o]=!0},shouldStopLoop:function(o){if(this.programKilledSoStopMonitoring)return!0;if(this.programNoLongerBeingMonitored)return!1;if(this._loopExits[o])return!1;var t=this._getTime();if(0===this.timeOfFirstCallToShouldStopLoop)return this.timeOfFirstCallToShouldStopLoop=t,!1;var i=t-this.timeOfFirstCallToShouldStopLoop;if(i<this.START_MONITORING_AFTER)return!1;if(i>this.STOP_ALL_MONITORING_TIMEOUT)return this.programNoLongerBeingMonitored=!0,!1;try{this._checkOnInfiniteLoop(o,t)}catch(n){return this._sendErrorMessageToEditor(),this.programKilledSoStopMonitoring=!0,!0}return!1},_sendErrorMessageToEditor:function(){try{if(this._shouldPostMessage()){var o={action:"infinite-loop",line:this._findAroundLineNumber()};parent.postMessage(JSON.stringify(o),"*")}else this._throwAnErrorToStopPen()}catch(t){this._throwAnErrorToStopPen()}},_shouldPostMessage:function(){return document.location.href.match(/boomerang/)},_throwAnErrorToStopPen:function(){throw"We found an infinite loop in your Pen. We've stopped the Pen from running. Please correct it or contact support@codepen.io."},_findAroundLineNumber:function(){var o=new Error,t=0;if(o.stack){var i=o.stack.match(/boomerang\S+:(\d+):\d+/);i&&(t=i[1])}return t},_checkOnInfiniteLoop:function(o,t){if(!this._loopTimers[o])return this._loopTimers[o]=t,!1;var i=t-this._loopTimers[o];if(i>this.MAX_TIME_IN_LOOP_WO_EXIT)throw"Infinite Loop found on loop: "+o},_getTime:function(){return+new Date}},window.CP.shouldStopExecution=function(o){return window.CP.PenTimer.shouldStopLoop(o)},window.CP.exitedLoop=function(o){window.CP.PenTimer.exitedLoop(o)};
效果还是挺不错的，你可以改变背景颜色等等定制。
jquery是一个简洁而快速的JavaScript库，它具有独特的链式语法和短小清晰的多功能接口、高效灵活的css选择器，并且可对CSS选择器进行扩展、拥有便捷的插件扩展机制和丰富的插件，是继Prototype之后又一个优秀的JavaScript代码库，能够用于简化事件处理、HTML文档遍历、Ajax交互和动画，以便快速开发网站。
