我在html代码中有5个分区,在第一个分区后有一个按钮"显示更多"已被放置。我想发一个jquery命令,它显示第二个部门点击按钮"显示更多"曾经和第三师再次点击按钮等等。
问题是我只能显示第二个分区并且第二次无法触发jquery脚本来显示第三个分区。
下面是我的Jquery和html。
$(document).ready(function(){
for(i=2;i<=5;i++)
{
$("#"+i).hide();
}
i=2; /* degrade the value of i */
$("button").on("click",function(){
//alert(i);
$("#button").remove();
$("#"+i).show();
var button="<button id='button' class='btn btn-primary'>show more</button>";
$("#"+i).after(button);
i=i+1;
});
});

你可以这样做。诀窍是:
$(":hidden").first().show()
<强>段强>
$(function () {
$("p:not(:first)").hide();
$("a").click(function (e) {
e.preventDefault();
$("p:hidden").first().show();
});
});
* {margin: 0; padding: 0; list-style: none; line-height: 1;}
p {display: inline-block; padding: 5px; border: 1px solid #ccc;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>Paragraph 1</p>
<p>Paragraph 2</p>
<p>Paragraph 3</p>
<p>Paragraph 4</p>
<p>Paragraph 5</p>
<a href="#">Show</a>
此外,您还可以再添加一项检查以查找是否还有隐藏的<p>
,然后您也可以删除该链接:
$(function () {
$("p:not(:first)").hide();
$("a").click(function (e) {
e.preventDefault();
$("p:hidden").first().show();
if (!$("p:hidden").length)
$(this).hide();
});
});
* {margin: 0; padding: 0; list-style: none; line-height: 1;}
p {display: inline-block; padding: 5px; border: 1px solid #ccc;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>Paragraph 1</p>
<p>Paragraph 2</p>
<p>Paragraph 3</p>
<p>Paragraph 4</p>
<p>Paragraph 5</p>
<a href="#">Show</a>

嗯,我想这是一个非常简短的解决方案:https://jsfiddle.net/hallleron/h6huonub/1/
使用detach()函数处理按钮。这样,您就不会丢失按钮的事件委派,而且资源密集程度也会降低。
关键部分是这一行:
var el = $('#button').detach();
$(document).ready(function(){
for(i=2;i<=5;i++)
{
$("#"+i).hide();
}
i=2;
$("button").on("click",function(){
var el = $('#button').detach();
$("#"+i).show();
$("#"+i).after(el);
i=i+1;
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="row">
<div class="col-md-4 col-sm-6 col-xs-12" id="1" style="border:1px solid red; height:200px; width:300px;"></div>
<button id='button' class='btn btn-primary'>show more</button>
<div class="col-md-4 col-sm-6 col-xs-12" id="2" style="border:1px solid red; height:200px; width:300px;"></div>
<div class="col-md-4 col-sm-6 col-xs-12" id="3" style="border:1px solid red; height:200px; width:300px;"></div>
<div class="col-md-4 col-sm-6 col-xs-12" id="4" style="border:1px solid red; height:200px; width:300px;"></div>
<div class="col-md-4 col-sm-6 col-xs-12" id="5" style="border:1px solid red; height:200px; width:300px;"></div>

编辑:添加了工作代码段。

这是因为初始化函数时第二个按钮不在DOM中。
而是使用它:
$('body').on('click', 'button', function(){
// Your code
});
$(document).ready(function(){
for(i=2;i<=5;i++)
{
$("#"+i).hide();
}
i=2; /* degrade the value of i */
$("body").on("click", "button" ,function(){
//alert(i);
$("#button").remove();
$("#"+i).show();
var button="<button id='button' class='btn btn-primary'>show more</button>";
$("#"+i).after(button);
i=i+1;
});
});

为什么要销毁你的按钮,然后尝试立即重新创建它?只需使用相同的按钮。否则,您将需要委托动态添加元素。
$("#button").click( () => $(`#${++i}`).show())
或者在ES5中:
$("#button").click( function(){ $("#" + (++i) }).show())
你说你正在摧毁按钮并重新创建它,所以它总是在最后显示的元素之后,好吧,将按钮直接放在所有隐藏的元素后面并留在这里......
答案 4 :(得分:0)
当您删除按钮并插入新按钮时,它没有附加您的点击处理程序。你可以做的是移动现有的按钮,它将保留点击处理程序。
$(document).ready(function() {
var i, $button = $('#button');
for (i = 2; i <= 5; i++) {
$("#" + i).hide();
}
i = 2; /* degrade the value of i */
$("button").on("click", function() {
var $i = $("#" + i);
$button.insertAfter($i);
$i.show();
i = i + 1;
});
});

确实,insertAfter
的文档提到了
如果以这种方式选择的元素被插入到DOM中其他位置的单个位置,则在目标(未克隆)之后将移动,并返回由inserted元素组成的新集合:

尝试这样做:

$("#" + i).hide();
}
var i = 2; /* degrade the value of i */
$("button").on("click", function() {

i = i + 1;
});
