The powers of jQuery and CSS selectors

Previously, I utilized the following code to extract text from the data-placeholder attribute and apply it as a placeholder for my div.

[contentEditable=true]:empty:not(:focus):before {
    content:attr(data-placeholder)
}

While this method worked well before, I am now facing a different scenario where the project is entirely jQuery-based. I am aware of jQuery functions such as .empty(), .before(), :not(), and .focus(). Can these be used together in the same way as CSS selectors when using jQuery?

var div = $([contentEditable=true]:empty:not(:focus):before);

If not, what would be a more efficient approach when dealing with multiple functions like this?

Answer №1

An easy way to implement this is by adding a style element:

var customRule ='[contentEditable=true]:empty:not(:focus):before {'+
   ' content:attr(data-placeholder)'+
'}';
$('head').append('<style>'+customRule +'</style>');
