			<content:encoded><![CDATA[<p>经常会遇到这样一个情况：浏览器弹出对话框，提示脚本运行时间过长，询问“停止”还是“继续”。那究竟各个浏览器是如何判断在什么时候才弹出此对话框呢？</p>
<ul>
<li>IE：执行超过500W条JScript引擎语句出现提示。</li>
<li>Firefox：执行超过10秒出现提示。</li>
<li>Safari：执行超过5秒出现提示。</li>
<li>Opera：无论执行多久都不会出现提示，最有耐性。</li>
<li>Chrome：执行超过约8秒（估计值）出现提示。</li>
</ul>
<p><strong>注：</strong>当弹出类似alert的模式对话框的时候，是不计时。</p>
<p><strong>举一反三：</strong></p>
<p>此外，桌面程序、FLash空间等等都会被系统所检测到内存、代码长度、CPU占用等的变化而在临界的时候发出提示。</p>
<p>这个是为了说明程序有多智能，并且照顾到用户的体验吗？非也，这个是属于消费者的知情权，因为用户在不知情的情况下，继续让代码执行就会导致这些程序出现各种各样的问题，例如内存溢出等，所以，弹出这个提示的根本出发点是保护程序。</p>
