getElementbyId.style doesn't appear in external js file intellisense

Question

Hi All I'm new to asp.net developement. I'm trying to resize the height of a side nav div via js as the content panes for various options are loaded into hidden divs of variable height. The code: var contentDom = document.getElementById(main-content); var sidebarDom = document.getElementById(sidenav-content); var temp = contentDom.offsetHeight; sidebarDom.style.height = temp + px; works fine in the header of the aspx page. However when moved to an exisiting js file I don't get .offsetHeight or .style or .innerHTML etc. displaying in intellisense and these options are not working for me. Any help here is greatly appreciated? many thanks Steve.

hi Amit. Thanks for your response. by generic object of javascript do you mean that the js file is unaware the the element main-content is a div when using document.getElementById(main-conent)? Can you suggest a syntax for the above statement that would allow visual studio editor to display the intellisense correctly? I've heard this is simply a bug in visual studio 2008. Best Steve.

hello friend the intellisense you are looking for will not appear because the element you identified is stored in a generic object of javascript so you can use the .style of .offsetY etc.. with the element if it supports these methods.... like a div doestn't have value property to support but class property is supported by div and it won't appear in the intellisense yet. use IDE like Aptana studio for better javascript intellisense and support... create you javascript here and run any where.... also mozilla firebug plugin of firefox will help you a lot while playing with java script. get it from here
