如果跨度显示设置为内联执行此操作

Question

I'm working on a .net website that validates an input and if it fails adds an inline style "display:inline;"

Im trying to use jQuery to see this style and add a class to the respective input field.

if(!!$('span.errorp').length ){
   alert('hi');
} 

the above is what im currently using to ensure i can target the correct tag which works,

I guess i need something similar too...

if(!!$('span.errorp').display:inline ){
    alert('hi');
} 

Answer 1

Try the following

if ($('span.errorp').css('display') === 'inline') {
  ...
}

Answer 2

You can use something like:

$('span.errorp').css('display', 'inline');

It's not necessary to check for length. If there are no matches, nothing happens.

Answer 3

if($('span.errorp[style=display:inline]')) {
    // do stuff
}
