问题:

How can I disable the new functionality in Internet Explorer 10 that shows a little 'x' in a textbox when it's focused and I have content in it?

回答1:

input[type=text]::-ms-clear {
    display: none;
}

In IE 10+, text inputs (input[type=text]) show a (x) button on the right-side on the field once you start typing, it's used to clear/remove the entered text value.

In Chrome, search inputs (input[type=search]) show a similar button.

If you prefer to remove either of them for IE10+ and/or Chrome. You can add the style below to hide this button from the input.

See it in action... http://codepen.io/sutthoff/pen/jqqzJg

/* IE10+ */
::-ms-clear {
  display: none;
}

/* Chrome */
::-webkit-search-decoration,
::-webkit-search-cancel-button,
::-webkit-search-results-button,
::-webkit-search-results-decoration { 
  display: none; 
}

This is how I did it

input[type=text]::-ms-clear
{
    display: none;
}

回答4:

input::-ms-clear{
   display:none;
}

This did the trick for me.

Note that the style and CSS solutions don't work when a page runs in compatibility view. I'm assuming that this is because the clear button was introduced after IE7, and so the IE7 renderer used in compatibility view doesn't see ::-ms-clear as a valid style heading.
