老版本的ExtAspNet如果在js中获得控件的值

yc2018nian · 发表于 2018-4-19 10:23:10

请问各位大神,我这里的一个项目使用的是老版本的ExtAspNet,现在需要用js获取控件的值,但是使用Ext.getCmp('<%=ddlProduction.ClientID%>').getValue()时提示Ext.getCmp(...) is undefined ,用尽了各种办法还是无法获取控件的值,请问该怎么才能获取啊

Ext.getCmp(...) is undefined应该是说这个控件找不到，把完整代码发出来看下

在这写Ext.ready(function(){ 或者 onReady 不是 $(function () {

yc2018nian · 发表于 2018-4-19 18:17:40

我之后已经发现这个问题了,也要把一开始引用的jquery.js取消掉,然后里边用Ext的方法,不能用jquery的,虽然已经解决了,还是谢谢各位了.感谢!
