Here is a fiddle:

Line in JQuery, that causes error:

return ( elem[ name ] = value );

This one seem to fail in JQuery since 1.7.1 at least


<input type="text" id="check"/><br/>

<input type="button" value="crash IE8!">



$('#check').val(5).prop('type', 'hidden');

The .attr() method can be used to set the content attribute on element creation, but type cannot be set in IE once the element has been created. If you were to use .attr(), jQuery simply throws an error in all browsers. Whether we do this in .prop() is debatable. I prefer to keep .prop() raw and low-level and rely on the user to know how to manipulate properties because there are exponentially more factors in dealing with properties.
