元素的淡入正在转移和调整

时间：2018-07-03 17:03:45

标签： javascript html css object fadein

我已经建立了一个简单的网站，用户可以在其中键入单词，结果逐渐淡入相应的div。问题在于，一些新创建的<p></p>并插入到DOM中会向左移动或动态调整。您可以在这里检查结果：https://icelandico.github.io/nato-alphabet-decoder/。 如何避免这种吸引力？

这是负责此效果的代码部分：

<div class="item result"> </div> 

 .result,
 .full-codes-list {
     width: auto;
     white-space: nowrap;
     margin: 0 auto;
     text-align: center;
 }

.result p,
.full-codes-list tr {
    font-size: 1rem;
    letter-spacing: 5px;
    padding: 15px 0;
    color: #05386b;
    animation: fadeIn 1s;
    text-align: left;
}

@keyframes fadeIn {
    from { opacity: 0}
    to { opacity: 1}
}


  function putInDom() {
    let newParagraph = document.createElement('p');
    newParagraph.innerHTML = result[counter];
    resultDiv.appendChild(newParagraph);
    counter < result.length - 1 ? counter ++ : clearInterval(wordInsert)
 }

function decode() {
  inputValue = searchValue.value;
  inputValue = inputValue.toUpperCase().split("").filter(character => 
  character.match(/[\S]/));
  result = (inputValue.map(letter => letter in alphabet ? alphabet[letter] :
  letter));
}

alphabet变量是一个存储字母和相关代码的对象。

尝试此CSS，您的样式表中提供了CSS。我刚刚添加了text-align: center 

.result p {
    font-size: 2rem;
    text-align: center;
}

OR 

.result, .full-codes-list {
    width: 300px;
    white-space: nowrap;
    margin: 0 auto;
    text-align: center;
}

答案 1 :(得分：0)

好吧，我发现只有先出现一个简短的单词然后再出现一个较长的单词，才是这种情况。为什么？好吧，因为它创建了一个带有最小单词的div到该单词的宽度。然后出现一个更长的单词，宽度增加。因此，第一个单词向左移一点。当您以相反的方式进行操作时：长单词比短单词首先不会移动。

因此设置一定的宽度（例如10％）可能会有所帮助；

看看是否可行。

答案 2 :(得分：0)

我认为使用CSS Flexbox（详细信息here）将使其完全稳定。

基本上，您只需将其添加到现有CSS的结尾：

.result {
    display: flex;
    width: 100%;
    justify-content: center;
    text-align: center;
    flex-flow: row wrap;
    margin: 0;
}

.result p {
    flex: 1 100%;
    text-align: center;
}

这是一个示例（图标不起作用）：

const clearButton = document.querySelector('.menu--clear--button');
const searchButton = document.querySelector('.menu--search--button');
const searchValue = document.querySelector('.menu--value');
const resultDiv = document.querySelector('.result');
const fullCodeListTable = document.querySelector('.table-codes');
const contentDivs = Array.from(document.querySelectorAll('.content'));
const menuButtons = Array.from(document.querySelectorAll('.button'));
let inputValue;
let result;
let counter = 0;
let wordInsert;

// Input Buttons

clearButton.addEventListener('click', clearInput);
searchButton.addEventListener('click', function() {
  clearResult();
  decode();
  intervalAppend();
});

searchValue.addEventListener('keydown', function(event) {
  enterSearch(event.key)
});

// Menu Buttons

menuButtons.forEach(function(button) {
  button.addEventListener('click', function(e) {
    let clickedIndex = menuButtons.indexOf(e.target);
    clearResult();
    hideAndShowNextButton(e.target);
    clearDivs();
    showProperDiv(clickedIndex);
  })
});

function decode() {
  inputValue = searchValue.value;
  inputValue = inputValue.toUpperCase().split("").filter(character => character.match(/[\S]/));
  result = (inputValue.map(letter => letter in alphabet ? alphabet[letter] : letter));
}

function putInDom() {
  let newParagraph = document.createElement('p');
  newParagraph.innerHTML = result[counter];
  resultDiv.appendChild(newParagraph);
  counter < result.length - 1 ? counter ++ : clearInterval(wordInsert)
}

function clearInput() {
  searchValue.value = '';
}

function enterSearch(event) {
  if (event === 'Enter') {
    clearResult();
    decode();
    intervalAppend();
  }
}

function intervalAppend() {
  wordInsert = setInterval(putInDom, 500)
}

function clearResult() {
  counter = 0;
  resultDiv.innerHTML = '';
  result = [];
}

function generateList() {
  clearContent();
  let newTableRowHeader = document.createElement('tr');
  let newTableHeader1 = document.createElement('th');
  let newTableHeader2 = document.createElement('th');
  newTableHeader1.innerHTML = 'Symbol';
  newTableHeader2.innerHTML = 'Code';
  newTableRowHeader.appendChild(newTableHeader1);
  newTableRowHeader.appendChild(newTableHeader2);
  fullCodeListTable.appendChild(newTableRowHeader);
  for (key in alphabet) {
    let newCodeRow = document.createElement('tr');
    let newRowDataChar = document.createElement('td');
    let newRowDataCode = document.createElement('td');
    newRowDataChar.innerHTML = key;
    newRowDataCode.innerHTML = alphabet[key];
    newCodeRow.appendChild(newRowDataChar);
    newCodeRow.appendChild(newRowDataCode);
    fullCodeListTable.appendChild(newCodeRow)
  }
}

function clearContent() {
  while (fullCodeListTable.firstChild) {
    fullCodeListTable.removeChild(fullCodeListTable.firstChild);
  }
}

function hideAndShowNextButton(element) {
  menuButtons.forEach(function(button) {
    if (button.classList.contains('hidden')) {
      button.classList.remove('hidden')
    }
    element.classList.add('hidden');
  })
}

function clearDivs() {
  contentDivs.forEach(function(div) {
    div.classList.add('hidden')
  })
}

function showProperDiv(index) {
  contentDivs[index].classList.remove('hidden')
}
