javascript - Closures in a for loop -


Closers in a loop are causing me problems I think I have to create another function to solve the problem Returns the function for, but I can not work with it's jQuery code

Here is a basic problem in a simple form: 

  function fu (val) {alert (val); } (Var i = 0; i & lt; 3; i ++) {$ ('# button' + i). Click (function () {foo (i);}); }

Naturally, clicking on any of three buttons will be given a warning 3. I want the functionality that will be warned by clicking on button 1, button 2 2 Will say etc.

How can I do this?

See the method. / P> 

  $ ('# button' + i) .bind ('click', {button: i}, function (event) {foo (event.data.button);});

From Docs:

Alternate EventData Parameter is not commonly used. Upon granted, this argument allows us to give additional information to the handler.

This parameter has to work around issues that are close to an easy use.

'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...
