javascript - How to tell if a web page is being exited/unloaded via flash versus via normal HTML -


I have a flash app, which redirects to another page. I would love to trap any other window loading (clicking on the link / submitting the form) and warn the user that they will lose their progress in the flash app.

However, I can not find a way to tell that the click / change of URL / window unloads is being started from Flash vs. Normal Links etc.

Is there any way to detect it, and how reliable is it?

There is no point in what happened to an unload event directly in the event handler. However, you can get it by attaching an onclick event handler to each link on that page which sets a variable. In jQuery: Click 

  $ ("A") (function () {window.clickedLink = this});

You can read the link clicked on your unload event and tell the difference.

This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
