javascript - How to figure out if the window is closing in the callback of jQuerys unload(); method -


Is it possible that the event triggered by this event is $ (window)? Unload (); ? To be a little more specific, I'm only interested in this event when a user has closed the window (a popup), and not just when navigating from the current page.

I have seen the callback of event parameter unload () passed; But nothing appears in that object, which will be of use.

Does anyone know this solution?

Code: 

  $ (function () {$ (window). Unload (function (event) {//} This is clearly the pseudo code. Please help! If (event.type == 'closed') {// I had some expectations with these lines to work // make the content before the windows closed}}}}};  No, this is not possible for my knowledge. The document only learns about the unloading. Why is the business of the browser.

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....
