Question

使用Asp.Net Web Services和Json-JQuery。我的代码很简单：加载aspx页面。单击按钮并调用Web服务。

它在Chrome中完美运行但在IE11中并不适用。即使我在浏览器控制台中执行一个简单的JQuery脚本，比如$（btnguardar），即返回undefined，chrome也会返回按钮。

有解决方法吗？

这是我的代码：（aspx文件）

由于

Answer 1

发现

$(btnAvanzar)

chrome和firefox支持

。但Internet Explorer需要以下语法

$("#btnAvanzar")

其他方式是

$(document.getElementById("btnAvanzar"))

然而写

需要太多
