A JQuery function for SVG, to execute 2nd animation as soon as, 1st animation completes?


I applied the animation-delay technique, but to achieve a the handwriting effect animation, I had to cut the object wherever it intersects, and drew a path and converted it to a clipping mask, e.g. letter "W" divided into 4 parts and drew different paths for different part for the said above, and animating it, to give a clean handwriting effect, giving path a stroke width, It took me a lot more time as the font was too complicated.

Currently I am achieving the said animation using animation-delay, CSS function.

CSS Code

#W2-Path {
    animation-delay: .5s
}

#W3-Path {
    animation-delay: 1s
}

#W4-Path {
    animation-delay: 1.5s
}

#O-Path {
    animation-delay: 2s
}

#R1-Path-2 {
    animation-delay: 3.5s
}

#R2-Path-2 {
    animation-delay: 4s
}

#R3-Path-2 {
    animation-delay: 4.5s
}

#L1-Path-2 {
    animation-delay: 5s
}

#L2-Path-2 {
    animation-delay: 5.5s
}

#L3-Path-2 {
    animation-delay: 6s
}

#D1-Path {
    animation-delay: 6.5s
}

#D2-Path {
    animation-delay: 7s
}

I was thinking if there is any other way through which I can start the 2nd animation as the 1st animation completes, and it just keeps going on giving the animation more smoother effect and perfect timing, implementing JQuery?

Solution

  • I'm answering only for the latter W

    I've changed the svg code you have, because it can be done in a more simple way.

    You are wrapping every line in 2 groups. I'm using just the lines. Also you are using style="clip-path: url(#clip-path)" I've transformed this to a presentational attribute like so: clip-path="url(#clip-path)" because in javascript I want to set the animation-delay as inline style for the lines.

    An other change: I'm using stroke-dasharray: 8 and stroke-dashoffset: 8 since 8 is the length of the lines for the letter W. I know the length of the lines because I've used the getTotalLength() method.

    The stroke and the stroke-width are set only once for the group since the lines for the letter have the same style.

    The javascript is selecting all the lines in a group and then is looping through the lines and setting the animation-delay:${i*1}s where i is the nth line. Please observe that the order of the lines in the group is from the first to the 4-th and not vice versa as you have them in your code.

    let Wls = document.querySelector("#W").querySelectorAll("line");//all the lines in the W group
    
    Wls.forEach((l,i)=>{
    // for each line in the W group
    // set the style attribute
      l.setAttribute("style", `animation-delay:${i*1}s`)
    })
    body {
    	background: white;
    }
    
    svg {
      width: 90vh; 
      border:solid;
    }
    
    
    #W line{
      stroke-dasharray: 8;
      stroke-dashoffset: 8;
      animation: letter-animation 1s linear forwards;
    }
    
    
    @keyframes letter-animation {
        0% {
            stroke-dashoffset: 8;
        }
        100% {
            stroke-dashoffset: 0;
        }
    }

    UPDATE

    The OP is commenting:

    So when I was actually trying to implement it, I got on the letter "O", its a path not a line, I tried your method, its not appearing for path, what can be done for that any clue?

    In this case you'll have to animate the path. This time you don't need a different css animation and since the final value for the stroke-dashoffset is 0 you don't need a different animation. However you'll need to calculate the path's total length to use it for the path's stroke-dasharray and stroke-dashoffse. In this case is 20.4.

    let Wls = document.querySelector("#W").querySelectorAll("line")
    
    Wls.forEach((l,i)=>{
      l.setAttribute("style", `animation-delay:${i*1}s`)
    })

    	background: white;
    }
    svg {

    #W line{

      animation: letter-animation 1s linear forwards;

    #O path{
