Where did you get this code?1. It is declared as HTML5 doctype but why at the same time <html xmlns="http://www.w3.org/1999/xhtml">2. There is this jQuery library, but you are using plain js code inside the jquery document.ready() method.Do read out:HTML Tutorial[^]; andjQuery Tutorial[^]Coming back to your question, if you want some action to take place (e.g changing the value interval to that in a text box) upon the happening of some event (e.g. changing of value in the text box), then you have to first bind that action to that event. As it is now, they are not bound. Check these out:JS onchange Event[^]; orjQuery .change()[^]After you have updated the interval value, clear the current timer, then start the timer with a new interval, how to do this? Ask Google.try this<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head > <title></title> <script src="jquery-1.8.2.js"></script> <script type="text/javascript"> 这篇关于我想在运行时由用户在javascript的setinterval中更改超时的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！ 08-23 12:34
