我有html,我从js
显示数组这是代码
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<div id ="container">
<div id="data"></div>
<input id="text" type=text/>
<button id="get" onclick="getValue()">Update</button>
</div>
这里是js代码
var tasks = ["Task 1", "Task 2"];
$.each(tasks, function(){
$('#data').append('<li class="clickable">'+this + '</li>');
});
我从列表中获取元素
$(document).on('click', '.clickable', function() {
var str = $(this);
});
现在我需要通过js攻击它。我怎么能这样做?

您可以点击strike
元素执行此操作:
var tasks = ["Task 1", "Task 2"];
$.each(tasks, function(){
$('#data').append('<li class="clickable">'+this + '</li>');
});
$(document).on('click', '.clickable', function() {
$(this).css("text-decoration", "line-through");
});
&#13;
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<div id ="container">
<div id="data"></div>
<input id="text" type=text/>
<button id="get" onclick="getValue()">Update</button>
</div>
&#13;
但是如果你想在每次点击时添加和删除点击,请使用:
var tasks = ["Task 1", "Task 2"];
$.each(tasks, function(){
$('#data').append('<li class="clickable">'+this + '</li>');
});
$(document).on('click', '.clickable', function() {
$(this).toggleClass('strikeClass');
});
&#13;
.strikeClass{
text-decoration: line-through;
}
&#13;
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<div id ="container">
<div id="data"></div>
<input id="text" type=text/>
<button id="get" onclick="getValue()">Update</button>
</div>

您有两种选择。
1)包裹del
标签
$(document).on('click', '.clickable', function() {
var str = $(this);
srt.wrap("<del></del>");
});
2)添加样式属性
$(document).on('click', '.clickable', function() {
var str = $(this);
str.css("text-decoration", "line-through");
});

如果您需要删除元素,只需执行onClick="$(this).remove();"
$(document).ready(function() {
$(document).on('click', '.clickable', function() {
$(this).remove();
});
var tasks = ["Task 1", "Task 2"];
$.each(tasks, function() {
$('#data').append('<li class="clickable">' + this + '</li>');
});
});
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<div id="container">
<div id="data"></div>
<input id="text" type=text/>
<button id="get" onclick="getValue()">Update</button>
</div>

我不明白你的意思
$(document).on('click', '.clickable', function() {
var txt = this.textContent;
this.innerHTML = txt.strike();
});
