jquery animate function initialize the value

问题

$(element).delay(2000).animate(
    {
        scale: 1,
    },
    {
        duration: 1000,
        step: function(now) {
            scaleVal = now;
            $(element).attr("transform", "translate(" + centerX + " " + centerY + ") scale(" + scaleVal + ") translate(" + (-centerX) + " " + (-centerY) + ")");
        }
    }
);

Now the scale value starts from 0 and ends up in 1 but instead of this I want to start from 0.5 and ends up in 1.

How can I initialize the scale value in animate function?

回答1:

you need to use css function

$(ele).css('scale', 0.5).animate({scale:1});
