fen*_*nec 3 javascript jquery jquery-ui jquery-plugins dom-events
我正在尝试构建一个与计时器链接的进度条.例如,每秒将增加1%到条的宽度.现在我到了我可以点击一个按钮的部分,它开始进展.但这纯粹是任意的.我怎么能得到某种无限循环用jquery来每秒后更新一次吧？另一个问题可能更基本？我如何使用按钮来停止栏的进展？
两个问题

听起来你正在寻找setInterval.
var timerId = setInterval(function() {
// code you want to execute every second here
}, 1000);
// 1 second = 1000 milliseconds.
然后,当您不再希望代码每秒运行时,您可以执行以下操作:
clearInterval(timerId);
