javascript - IE slowing down after updatepanel partial update -


I am trying to keep a user control inside an UpdatePanel when the control is displayed, then text box Typing inside is a bit late in IE (6 and 8). Firefox's excellent performance is not only typing but also the scrolling experience for a few seconds.

User control (s) has a lot of JavaScript functions, which is ScriptManager.RegisterScriptBlock or register startupscript function .

Is there any idea why typing becomes so slow? I believe this is something to do with memory leaks due to the re-registration of jQuery functions. But I am unable to locate its source.

Javascript Whether you wrote by yourself or others or a trusted framework Is part of? Generic Tips: - Reduce processes and function calls - Representative events - Reuse cache and jQuery results (especially for IE) and when you know that the dom has changed. - Avoid recurrence until you know how to avoid all memory leak prone practices. - About form input, use 'focus' and 'blur' events, instead you can 'keypress' wherever you can. - When using 'keypress' events, Debian, Debans, Debans! (Google this)

Use: - To see the firebug profiler, which function is called and how often, it shows you why you need to reduce.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
