[英]How to append each two divs to a div?
I have this list: 我有这个清单:
<div id="list">
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
</div>
I want to move each two elements (.item) inside a div with class="parent"
. 我想在每个带有class="parent"
的div中移动两个元素(.item)。 I tried with the following, but it doesn't work: 我尝试了以下操作,但不起作用:
var parent = $("<div class='parent'></div>");
$("#list .item:nth-child(1), #list .item:nth-child(2)").appendTo(parent);
$("#list .item:nth-child(3), #list .item:nth-child(4)").appendTo(parent);
$("#list .item:nth-child(5), #list .item:nth-child(6)").appendTo(parent);
parent is a single cached element so each time you use it it will not create a new parent. parent是单个缓存的元素,因此每次使用它都不会创建新的父元素。 Not sure if you looking for something like .wrap()? 不知道您是否正在寻找类似.wrap()的东西? http://api.jquery.com/wrap/ or .wrappAll() http://api.jquery.com/wrapAll/ http://api.jquery.com/wrap/或.wrappAll() http://api.jquery.com/wrapAll/
$('#list').children().wrapAll('<div class="parent"/>');
Store the childrens in an array, then create as many parents as needed and put them back in your list, here is the code: 将孩子存储在一个数组中,然后根据需要创建尽可能多的父母,并将其放回列表中,代码如下:
var list = $("#list"),
items = $.makeArray($(".item"));
list.html("");
for (var i=0; i < items.length; i++) {
if (i%2 == 0) list.appendChild($('<div class="parent"/>'));
$("#list div:last-child").appendChild(items[i]);
}
You can wrap each two child element like this: 您可以像这样包装每两个子元素:
var childLists= $('.item');
for(var i = 0, l = childLists.length; i < l; i += 2) {
childLists.slice(i, i+2).wrapAll('<div class="parent"></div>');
}
You can use wrapAll()
method as follows: 您可以如下使用wrapAll()
方法:
$(".item:even").each(function(){ $(this).next().addBack().wrapAll("<div class='parent'></div>"); })
*{ margin:0; padding:0; } body{ background:silver; } .parent{ height:100px; padding:5px; margin:5px; text-align:center; background:dodgerblue; } .item{ height:40px; line-height:40px; margin:5px 0; background:#fff; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="list"> <div class="item">1</div> <div class="item">2</div> <div class="item">3</div> <div class="item">4</div> <div class="item">5</div> <div class="item">6</div> </div>
you can try this:without wrap you can get it. 您可以尝试以下方法:无需包装即可获得。
<script>
$(document).ready(function(){
var parent = document.createElement("div");
parent.className = "parent";
x = document.getElementById("list");
parent.appendChild(x);
document.body.appendChild(parent);
});
</script>
<div id="list">
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
</div>
