清除jquery.animate（）中元素的最高值

Question

I have this css:

.hacer .contenido .caja .texto {
    position: absolute;
    bottom: -30px;
}

and I have this jquery

 var cajasHacer = $('.hacer').find('.contenido').find('.caja');

        cajasHacer.each(function () {

        $(this).mouseenter(function() {
            $(this).find('.texto').animate({top: '40px'} , 300);
        });

        $(this).mouseleave(function() {
            $(this).find('.texto').animate({ top: 'auto'} , 300);
        });
    });

I have used values for top: initial,unset and auto, but it doesn't clear the top value of the element and travel to bottom again when mouse leaves.

Answer 1

You can reset the top value through removing the style attribute values using .removeAttr() method.

var cajasHacer = $('.hacer').find('.contenido').find('.caja');

    cajasHacer.each(function () {

    $(this).mouseenter(function() {
        $(this).find('.texto').animate({top: '40px'} , 300);
    });

    $(this).mouseleave(function() {
        $(this).find('.texto').removeAttr('style');
    });

});

I think, you should store the initial top value of the element in a variable. So, when the mouseleave event triggers, you can add it to your element.

var topPos = $(element).offset().top;

and in your code:

var cajasHacer = $('.hacer').find('.contenido').find('.caja');

        cajasHacer.each(function () {

        $(this).mouseenter(function() {
            $(this).find('.texto').animate({top: '40px'} , 300);
        });

        $(this).mouseleave(function() {
            $(this).find('.texto').animate({ top: topPos} , 300);
        });
    });
