JavaScript IE8 Error - Object doesnt support This Property

Question

IE 8 says: it doesn't support this property or method:

Code is here (Error in coming in this whole part):

$('li').has('ul').mouseover(function(){
    $(this).children('ul').css('visibility','visible');
}).mouseout(function(){
    $(this).children('ul').css('visibility','hidden');
})

This code is a part of this function:

if ($.browser.msie && $.browser.version.substr(0,1) < 7) {
    $('li').has('ul').mouseover(function(){
        $(this).children('ul').css('visibility','visible');
    }).mouseout(function(){
        $(this).children('ul').css('visibility','hidden');
    })
}

What is wrong with this.. please help.

Answer 1

我不确定，但是小的修正使用$('li ul')而不是$('li').has('ul')
