jsのreportValidity()を呼ぶとiosのsafariが落ちるバグの解消法

結論

validationが画面に表示されているときにもう一度reportValidity()を呼ぶと落ちる。
よって、setTimeoutとかでくくってやればいい。

問題のコード

validate.js
$("#form").find("input, select, textarea").on('blur', function(){didBlurInput()});

function didBlurInput(){
  $("#form").reportValidty();
}

blurした時に直でこれを呼ぶとまだ画面上にvalidationを表示する文字が表示されている。
画面上にvalidationを表示する文字が表示されている状態でもう一度reportValidty()を呼ぶとiOSのsafariだとバグって落ちる

解決したコード

validate.js
$("#form").find("input, select, textarea").on('blur', function(){didBlurInput()});

function didBlurInput(){
  setTimeout(function(){
    $("#form").reportValidty();
  }, 100);
}

よって次のようにしてやればblurが終わってvalidationの表示が消えてからreportValidty()が呼ばれるのでsafariが落ちなくなった。
