In jQuery, you can add an attribute to an element by using the attr function. You can also remove an attribute using the removeAttr function.
And when I define an attribute of css through the function $.css ? How do I remove?
The simplest solution would be to zero the element:
$.css("background-color", ""); // exemplo com background-color
Example:
$(function(){
var contador = 0;
$(".btn").click(function(){
if(contador == 0)
{
$(this).css("background-color", "blue");
contador = 1;
}
else
{
$(this).css("background-color", "");
contador = 0;
}
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><buttonclass="btn">Exemplo</button>Source: StackOverflow
Remove a CSS attribute:
$(el).css("color", "");
Remove multiple CSS attributes:
$(el).css({
"color": "",
"background-color": "",
"outline": "",
});
