快速搜索谷歌会显示这个脚本

// create function, it expects 2 values.
function insertAfter(newElement,targetElement) {
    // target is what you want it to go after. Look for this elements parent.
    var parent = targetElement.parentNode;

    // if the parents lastchild is the targetElement...
    if (parent.lastChild == targetElement) {
        // add the newElement after the target element.
        parent.appendChild(newElement);
    } else {
        // else the target has siblings, insert the new element between the target and it's next sibling.
        parent.insertBefore(newElement, targetElement.nextSibling);
    }
}

步骤1。准备要素:

var element = document.getElementById('ElementToAppendAfter');
var newElement = document.createElement('div');
var elementParent = element.parentNode;

步骤2。在后面追加:

elementParent.insertBefore(newElement, element.nextSibling);

简单的JavaScript代码如下:

附加:

element.parentNode.insertBefore(newElement, element);

添加后:

element.parentNode.insertBefore(newElement, element.nextSibling);

但为了便于使用，可以在这里添加一些原型:

通过构建以下原型，您将能够直接从新创建的元素调用这些函数。

newElement.appendBefore(元素); newElement.appendAfter(元素);

.appendBefore(元素)的原型

Element.prototype.appendBefore = function (element) {
  element.parentNode.insertBefore(this, element);
},false;

.appendAfter(元素)的原型

Element.prototype.appendAfter = function (element) {
  element.parentNode.insertBefore(this, element.nextSibling);
},false;

代码片段以查看所有操作:

/* Adds Element BEFORE NeighborElement */ Element.prototype.appendBefore = function(element) { element.parentNode.insertBefore(this, element); }, false; /* Adds Element AFTER NeighborElement */ Element.prototype.appendAfter = function(element) { element.parentNode.insertBefore(this, element.nextSibling); }, false; /* Typical Creation and Setup A New Orphaned Element Object */ var NewElement = document.createElement('div'); NewElement.innerHTML = 'New Element'; NewElement.id = 'NewElement'; /* Add NewElement BEFORE -OR- AFTER Using the Aforementioned Prototypes */ NewElement.appendAfter(document.getElementById('Neighbor2')); div { text-align: center; } #Neighborhood { color: brown; } #NewElement { color: green; } <div id="Neighborhood"> <div id="Neighbor1">Neighbor 1</div> <div id="Neighbor2">Neighbor 2</div> <div id="Neighbor3">Neighbor 3</div> </div>

在JSFiddle上运行它

可以使用appendChild函数在元素之后插入。

参考:http://www.w3schools.com/jsref/met_node_appendchild.asp

你可以在新版本的Chrome, Firefox和Opera中调用after()方法。这种方法的缺点是Internet Explorer还不支持它。

例子:

// You could create a simple node
var node = document.createElement('p')

// And then get the node where you want to append the created node after
var existingNode = document.getElementById('id_of_the_element')

// Finally you can append the created node to the exisitingNode
existingNode.after(node)

一个简单的HTML代码来测试: <！DOCTYPE html > < html > 身体< > < p id =“了”> < / p > < p id = "下来“> < / p > <button id="switchBtn" onclick="switch_place()“>开关的地方> < /按钮 <脚本> 函数switch_place () { var downElement = document.getElementById("down") var upElement = document.getElementById("up") downElement.after (upElement); . getelementbyid(“switchBtn”)。innerHTML = "切换!" ｝ > < /脚本 < /身体> < / html >

正如预期的那样，它在向下的元素之后移动向上的元素

if( !Element.prototype.insertAfter ) {
    Element.prototype.insertAfter = function(item, reference) {
        if( reference.nextSibling )
            reference.parentNode.insertBefore(item, reference.nextSibling);
        else
            reference.parentNode.appendChild(item);
    };
}
