问题描述
好吧，这有点难以解释这一点，但我试图做在每当一个数字是产生或生成，它淡入，而不是只是弹出。
这里是我试图做的小提琴。我使用输入标记为数字和为语句生成其余 -
Okay so this is a bit hard to explain this, but I am trying to make where whenever a number is "spawned" or generated, it fades in instead of just popping up.
Here is the Fiddle that I am trying to do that with. I am using a input tag for the number and a for statement to generate the rest--
for (I = 0; I < $("#input:text").val(); I++) {
N.innerHTML += 1 + I + " "
}
我希望我解释得很好足够让人理解！
I hope I explained that well enough so people understand!

附加
span
Append
spanelements instead oftextso that you can easily select elements using selector.
p>使用 setTimeout 可以使用 index 连续发生。
Use setTimeout to make it happen serially using index.
尝试此操作：
var D = document,
In = D.getElementById("input"),
CC = D.getElementById("submit"),
N = D.getElementById("N"),
I;
$(In).keyup(function(Key) {
if (Key.keyCode == 13) {
for (var i = 0; i < $("#input:text").val().length; i++) {
var span = '<span style=\'display:none\'>' + (i + 1) + ' ' + $("#input:text").val()[i] + ' </span>'; //set display of `span` element as `none`
N.innerHTML += span;
}
}
$('#N span').each(function(i) {
setTimeout(function() {
$(this).hide().fadeIn(500);
}.bind(this), (i * 500)); // `.bind()` will pass the outer `this` context in`setTimeout` when handler is invoked
})
});
$(CC).click(function() {
N.innerHTML = "";
});
body {
cursor: default;
outline-width: 0px;
}
#main {
text-align: center;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<body>
<div id="main">
<input type="text" id="input" maxlength="3" placeholder="Press submit to clear all" />
<input type="submit" id="submit" />
</div>
<h1 id="N"></h1>
</body>
