Thank you in advance. 解决方案 ygulve wrote:document.getElementById('<%=txtTime.ClientId%>')"Do a viewsource of your page. Find the ID value of the textbox in it. Lets say it is "ctl00_txtTime" then use:document.getElementById('ctl00_txtTime') for getting the textbox object.when you use client Id in dotnet 3.5 sure was an erorrtxtTime.ID in dot net 3.5 or 3 txtTime.ClientId in dot net 4but ID not ClientId in dot net forcheck this onehttp://www.dreamtheweb.com/2013/12/pass-textbox-value-into-javascript.html 这篇关于如何将asp.net文本框控件传递给JavaScript函数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！
