回忆我的textille动画的问题

Question

我想为我的段落制作动画，点击按钮后会更换内容。因此按钮#start_animation应该启动textillate in动画，而按钮#out_animation应该会导致out动画。然后我点击第三个按钮#replaced_word，它取代了我的段落的内容。

重要提示：我总是点击同一行：

1. #start_animation

2. #out_animation

3. #replaced_word

所以这个词应该是一个动画（fadeIn），然后是另一个动画（fadeOut），然后被替换，然后我再次点击第一个按钮#start_animation和它一遍又一遍。问题是它只是第一次起作用。我的意思是直到我第二次点击#start_animation。我之前用代码写了这个问题，但是它太长了所以我以片段的形式做了。有什么想法吗？

$('#start_animation').click(function() {
  $('#sample_text').textillate('in');
  $('#paragraph').textillate('start');
  $('#paragraph').addClass('show');
});

/*-----------------------------------------------*/

$("#out_animation").click(function() {
  $('#sample_text').textillate('out');
  $('#paragraph').textillate('out');
  setTimeout(function() {
    $('#paragraph').removeClass('show');
  }, 1000);
});

var words = ["peter", "michael", "john", "derek", "chris"];

function replacing() {
  document.getElementById('paragraph').innerHTML = getRandomItem(words);
}

var btn2 = document.getElementById("replaced_word");

btn2.addEventListener("click", replacing);

function getRandomItem(array) {
  return array.splice(Math.floor(Math.random() * array.length), 1)[0];
}

/*-----------------------------------------------*/

$(function() {
  $('#paragraph').textillate({
    loop: false,
    autoStart: false,
    in: {
      effect: 'fadeIn',
      shuffle: false,
      delay: 80
    },
    out: {
      effect: 'fadeOut',
      shuffle: false,
      delay: 40,
      reverse: true
    }
  });
})

.show {
  opacity: 1!important;
}

#paragraph {
  opacity: 0;
}

Answer 1

问题是，每次更换段落中的文本时，都需要“重置”插件。好吧，你还需要替​​换元素DOM本身，否则插件将无法执行任何操作，因为它已经附加了DOM元素。

$('#start_animation').click(function() {
  $('#sample_text').textillate('in');
  $('#paragraph').textillate('start');
  $('#paragraph').addClass('show');
});

/*-----------------------------------------------*/

$("#out_animation").click(function() {
  $('#sample_text').textillate('out');
  $('#paragraph').textillate('out');
  setTimeout(function() {
    $('#paragraph').removeClass('show');
  }, 1000);
});

var words = ["peter", "michael", "john", "derek", "chris"];

function replacing() {
  $('#paragraph').replaceWith('<p id="paragraph">' + getRandomItem(words) + '</p>');
  init();
}

var btn2 = document.getElementById("replaced_word");

btn2.addEventListener("click", replacing);

function getRandomItem(array) {
  return array.splice(Math.floor(Math.random() * array.length), 1)[0];
}

function init() {
console.log('init');
  $('#paragraph').textillate({
    loop: false,
    autoStart: false,
    in: {
      effect: 'fadeIn',
      shuffle: false,
      delay: 80
    },
    out: {
      effect: 'fadeOut',
      shuffle: false,
      delay: 40,
      reverse: true
    }
  });
}

/*-----------------------------------------------*/

$(function() {
  init();
});

.show {
  opacity: 1!important;
}

#paragraph {
  opacity: 0;
}

<button id="out_animation">out animation</button>
<button id="replaced_word">replace word</button>
<p id="paragraph">TEST</p>

顺便说一句，为什么你需要手动完成所有这些工作人员？该插件似乎具有手动替换文本与转换的功能。

Answer 2

当您操作DOM以更改段落的文本时，textillate事件不再绑定到它。

一个简单的解决方案是使用<p id="paragraph"><span id="paragraph_text">TEST</span></p>并仅在#paragraph_text

上执行DOM操作

此外，我注意到$('#sample_text')未被使用，可以删除。

$('#start_animation').click(function() {
  $('#paragraph').textillate('start');
  $('#paragraph').addClass('show');
});

/*-----------------------------------------------*/

$("#out_animation").click(function() {
  $('#paragraph').textillate('out');
  setTimeout(function() {
    $('#paragraph').removeClass('show');
  }, 1000);
});

var words = ["peter", "michael", "john", "derek", "chris"];

function replacing() {
  document.getElementById('paragraph_text').innerHTML = getRandomItem(words);
}

var btn2 = document.getElementById("replaced_word");

btn2.addEventListener("click", replacing);

function getRandomItem(array) {
  return array.splice(Math.floor(Math.random() * array.length), 1)[0];
}

/*-----------------------------------------------*/

$(function() {
  $('#paragraph').textillate({
    loop: false,
    autoStart: false,
    in: {
      effect: 'fadeIn',
      shuffle: false,
      delay: 80
    },
    out: {
      effect: 'fadeOut',
      shuffle: false,
      delay: 40,
      reverse: true
    }
  });
})

.show {
  opacity: 1!important;
}

#paragraph {
  opacity: 0;
}
