SVG路徑動畫從單擊按鈕開始

Question

我有一個SVG路徑動畫，此動畫目前處於無限循環中。 我希望動畫在單擊事件觸發之前是不可見的，然后一旦動畫完成（一次，不是無限次），該按鈕將不再起作用。

我添加了一個測試按鈕，但加載頁面后該動畫似乎仍然可以播放，並且該按鈕對此沒有任何作用。

 $("#button").click(function() { $('.dashed').toggleClass('path'); }); 

 .dashed{ stroke-dasharray: 10; } .path { stroke-dasharray: 1000; stroke-dashoffset: 1000; animation: dash 5s linear infinite; } @keyframes dash { from { stroke-dashoffset: 1000; } to { stroke-dashoffset: 0; } }

Answer 1

a）清空類.path但將其保留在該位置：

.path { }

b）將從.path刪除的動畫屬性添加到新的CSS類中，並將動畫屬性中的'infinite'替換為'1'。

.path-animation {
     stroke-dasharray: 1000;
     stroke-dashoffset: 1000;
     animation: dash 5s linear 1;
}

c）使用以下jquery來獲得所需的結果：

$("#button").click(function() {
   $('.path').attr('class', 'path path-animation');
   //5 secs delay to complete the animation before removing it and disabling the button.
   setTimeout(function() {
      $('.path').attr('class', 'path');
      $("#button").attr("disabled","disabled");
   }, 5000);
});

Answer 2

您需要對代碼進行以下小的更改：

1）首先從第一個<path>元素中刪除已經存在的<path class="path" 。 您希望按鈕稍后在點擊時添加

2）從animation: dash 5s linear infinite;更改動畫迭代計數 animation: dash 5s linear infinite; -這里的“無限”表示對動畫進行無限次迭代。 將其更改為animation: dash 5s linear 1;

.path {
  stroke-dasharray: 1000;
  stroke-dashoffset: 1000;
  animation: dash 5s linear 1;
}

3）然后在第一次單擊后禁用該按鈕，您可以

$('#button').on('click', function() {
  $('.dashed').addClass('path');
  $(this).prop('disabled', true);
});

簡單..讓我知道您是否遇到任何問題。

檢查這個..應該會幫助...

對於禁用按鈕，您可以使用此代碼

$("#button").click(function() {
          $('.path').css("animation"," dash 5s linear");
          $(this).attr("disabled","disabled");
         });
