Syntax error on a dropdownlist control

Author Name Status Posted Time Fang Poon 3/15/2009 11:08:56 PM Author is Offline Hi everybody, I'm trying to use a .js file to get autocomplete on a dropdownlist control in my ASP.NET application, but keep getting a syntax error. The error on the .js file is: Line 15, Char 1, Object Expected: var keys; var timeStamp; timeStamp = new Date(); function dd_onkeypress(DropDownList1) { var key = event.keyCode; event.returnValue=false; //a-z, A-Z, 0-9 if ((key>=97 && key<=122) || (key>=65 && key<=90) || (key>=48 && key<=57)) { key = String.fromCharCode(key); var now = new Date(); var diff = (now.getTime() - timeStamp.getTime()); timeStamp = new Date(); //1 seconds = 1000 milliseconds<BR> if (diff > 1000) { keys = key; } else { keys = keys + key; } var cnt; for (cnt=0;cnt<document.all (DropDownList1).children.length;cnt++) { var itm = document.all(DropDownList1).children[cnt].text; if (itm.substring(0,keys.length).toLowerCase()==keys.toLowerCase()) { document.getElementById(DropDownList1).selectedIndex = cnt; break; } } } //document.all(DropDownList1).onchange(); } In my Page_Load .aspx page, I've got: DropDownList1.Attributes.Add("onkeyup", "javascript:return dd_onkeypress(this);") Thank you Fang.

Fang Poon 3/16/2009 12:10:24 AM Sorry, the "Object Expected" is pointing to the HTML line of the .aspx page for the a sp:dropdownlist tag, and not the .js file Post Comments Re: Please post your ASP.NET code-behind Evzon Ologio 3/16/2009 12:11:04 AM Please post your ASP.NET code-behind and let me kn ow which is line 15?

The code behind is: DropDownList1.Attributes.Add("onkeypress", "javascript:dd_onkeypress(this);return false;") Line 15 is the HTML of: <asp:dropdownlist Post Comments Re: Have you declared DropDownList1?
