javascript - 在 Javascript 中动画文本

转载作者：可可西里更新时间：2023-11-01 13:23:53

所以我的问题是我想在您按下回车键后在 js 中为文本(不透明度)设置动画，但我不知道如何使用我编写的代码来实现。我无法解释为什么我不能制作动画，但我可以展示我所有的代码，你会明白的。

function handle(e){
        if(e.keyCode === 13){
            e.preventDefault();
            theaction();
        }
    }
    function sleep(milliseconds) {
  var start = new Date().getTime();
  for (var i = 0; i < 1e7; i++) {
    if ((new Date().getTime() - start) > milliseconds){
      break;
    }
  }
}

function titleCase(str) {
     str = str.toLowerCase().split(' ');

     for(var i = 0; i < str.length; i++){
          str[i] = str[i].split('');
          str[i][0] = str[i][0].toUpperCase();
          str[i] = str[i].join('');
     }
     return str.join(' ');
}
function theaction() {
	var int = document.getElementById("every").value;
	var inp = int.toUpperCase();
	var lop;

对于奇怪的 ID 和函数名称，我深表歉意。没有 jquery plz，即使它会使它更容易。

P.S 即使你帮不了我，如果你能改进我的代码就好了。谢谢(:

最佳答案

如果我理解，要在呈现的文本上设置不透明度动画，您将:将过渡属性设置为 output 段落(已在您的 css 中设置)并在您的句柄函数中添加以下代码；

function handle(e){
  if(e.keyCode === 13){
    e.preventDefault();

    //---- added code
    document.getElementById("output").style.opacity = 0;
    setTimeout(function(){
      theaction();
      document.getElementById("output").style.opacity = 1;
    },500);
    //----
  }
}

所以首先将不透明度设置为 0 等待 500 毫秒后执行 theaction(); 并再次将不透明度设置为 1 ( css transition将制作动画)

在工作 fiddle 下面:

function handle(e){
  if(e.keyCode === 13){
    e.preventDefault();
    document.getElementById("output").style.opacity = 0;
    setTimeout(function(){
      theaction();
      document.getElementById("output").style.opacity = 1;
      //alert("yo")
    },500);
  }
}
function sleep(milliseconds) {
  var start = new Date().getTime();
  for (var i = 0; i < 1e7; i++) {
    if ((new Date().getTime() - start) > milliseconds){
      break;
    }
  }
}

function titleCase(str) {
   str = str.toLowerCase().split(' ');

   for(var i = 0; i < str.length; i++){
        str[i] = str[i].split('');
        str[i][0] = str[i][0].toUpperCase();
        str[i] = str[i].join('');
   }
   return str.join(' ');
}
