Hello Sir

I have designed a WebUser Control in asp .Net.There is a DropDowList control called ''ddlCity'' in the Usercontrol. I have used that user control in a content page. So how can i access the value of the DropDownList which is in Usercontrol from the Master page using Javascript. Plz help me Sir.

推荐答案

DropDownList的值，该值位于使用Javascript从母版页的Usercontrol中
一旦构建了整个页面，就没有HTML格式的主页面内容页面用户控件.将所有内容合并在一起，并形成HTML的单个页面.因此，从母版页访问usercontrol的控件将与在母版页上访问的控件相同.

试试:

value of the DropDownList which is in Usercontrol from the Master page using Javascript
Once the whole page is constructed, there is no master page-content page-user control in HTML format. All are clubbed together and a single page in HTML is formed. Thus, accessing a control of usercontrol from master page would be same as accessing a control on master page.

Try:

var dllcontrol = document.getElementById("<%=ddlCity.ClientID %>");
