javascript - Have newer versions of Internet Explorer fixed circular references memory leak? -


I am currently working in a project with Long Expatriate Pages (LLP), about the performance and memory leaks There is a need to worry about After reviewing some people, I have found that this may lead to a memory leak: 

  function addHandler () {var el = document.getElementById (' El '); El.onclick = function () {this.style.backgroundColor = 'red'; }; }

At first I did not understand, but it was easy to get many explanations for it. I have got a more detailed explanation on CodeProject and it is from Douglas Crockford.

Now my question is:

As far as I can understand, this specific leak is a IE-only bug Is it true? And, more important: As long as we do not have a version of Uncle Bill's company from Dear Blue Browser , then should I be worried about this leak?

Edit:

References about reliable final questions are desirable.

Edit # 2:

Maybe I'm wrong, but I think using the 'new' standardized interface for events, we get the same problem: 

  function addHandler () {var el = document.getElementById ('el'); El.addEventListener ('click', function () {this.style.backgroundColor = 'red';}); }

Since there is no direct task, I think this solves the problem, however, this API is only IE9 +, I wonder if we have the same problem as libraries fallback Is, such as jQuery: 

  var $ el = $ ('.h-el'); $ El.on ('click', function () {// ...});

I have to say that what this part of the code does on IE8 - there is not enough information about jQuery.

Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help?

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date ().
