AJAX & ASP.net, Referencing server controls in external file

由 ∥☆過路亽．° 提交于 2019-12-12 12:29:10
问题 I've got some JavaScript in an ASP.NET page that looks like this: var list = $get('<%=Topics.ClientID %>'); I have many functions written now where this syntax is used, and I would like to centralize my JavaScript and move this into an external JavaScript file.

I assume I should pass the control/control information as a parameter to the function, but I can't seem to get the syntax to work.
