我有一个通过jQuery创建的简单div ....
var split = document.createElement('div');
split.className ="item split";
$(split).html('<strong>SPLITTER</strong>');
我想在几个简单的函数中使用相同的变量。但是,似乎每当我将变量移出函数时,我只能创建一次div。然后所有其他实例都无法插入div。
测试代码段,它可能有助于更好地解释。
// Variable is created WITHIN the click function
$('#divide_btn').on('click', function() {
var split = document.createElement('div');
split.className = "item split";
$(split).html('<strong>SPLITTER</strong>');
$(split).hide(function() {
//stuff
}).insertAfter('.moved:last').slideDown(300);
});
// Variable is created OUTSIDE the click function.
var split2 = document.createElement('div');
split2.className = "item split";
$(split2).html('<strong>SPLITTER 2</strong>');
$('#divide_btn2').on('click', function() {
$(split2).hide(function() {
//stuff
}).insertAfter('.moved:last').slideDown(300);
});

body {
padding: 0 20px;
margin: 0;
}
span {
display: inline-block;
margin: 5px;
background: #aaa;
color: #eee;
padding: 5px 10px;
}
.item,
.moved,
.split {
padding: 5px 10px;
margin: 3px;
background: #eee;
}
.moved {
background: #fee;
}
.split {
background: #aaa;
}

<div class="main">
<div class="item">item</div>
<div class="item moved">item</div>
<div class="item">item</div>
<div class="item">item</div>
</div>
&#13;
注意区别&#34;内部&#34;按钮div在点击功能中创建,每次点击新div时都会创建(如预期的那样)。
对于&#34;外部&#34;按钮变量创建外部单击功能,只能创建一个div。
有没有办法为动态div使用外部变量,并且能够在函数中使用该变量,如果变量是内部的,函数的运行方式是相同的吗?
我正在寻求&#34;内部&#34;的功能。按钮..但我希望在所有我的函数中使用相同的变量,并且无需在需要的每个函数中复制div创建。
(注意动态div永远不会改变......因此,一旦设置了变量,就不需要编辑它。)
