Unable to focus an input using JavaScript in IE11

Question

I\'m unable to get IE11 to focus an input element after it is inserted into the DOM. The element won\'t receive text input after being focused, but its placeholder text is n

Answer 1

I don't think that your issue is coming from the focus() function, I think it's coming from the selector.

To prove it I just opened my IE11 and tried to focus the SO search input on the top right of the page using the following command:

document.getElementById('search')[0].focus()

So, just open your IE console (F12) and type that, it should focus the search input. If so, then the issue is coming from the selector which isn't an input as you may think.

It works on my IE 11.0.9600.17905

Answer 2

The issue was focusing in IE11 is broken when the css property -ms-user-select: none is applied to the input. So by changing:

* {
  -ms-user-select: none;
}

into

*:not(input) {
  -ms-user-select: none;
}

I was able to solve the problem. Here is a codepen for reproducing the issue: http://codepen.io/anon/pen/yNrJZz

Answer 3

As stated in https://stackoverflow.com/a/31971940, running element.focus() has no effect in IE11 when the css property -ms-user-select: none is set. A workaround can be

element.style['-ms-user-select'] = 'text';
element.focus()
element.style['-ms-user-select'] = '';

Does not work in IE: https://codepen.io/macjohnny-zh/details/WPXWvy

Works in IE, too: https://codepen.io/macjohnny-zh/details/LqOvbZ

Note: this also happens e.g. for

:-ms-input-placeholder {
  -ms-user-select: none;
}
