// css
.a,.b,.c,.d {
 display: none;
}
// num
var matchList = ['a','b','c','d'];
$('.'+matchList[num]).show().siblings().hide();

Don't write too much, two lines of code are done.

you can set their initial styles to hide,
switch.

Don't those svg have a div outside, give it a class name (and give it an id, such as-sharpsvg-container), and then use the script to change only the class name of div. Through the css set in advance to control the display of aPermine bPerry cPerry d under different conditions.

  1. set the style first 

    $('-sharpsvg-container').attr('class','c'+ num);  //num-sharpsvg-containersvgdiv
