我正在使用wordpress,我想在页面上使用Javascript添加一些HTML代码。我不想制作儿童主题,然后编辑php文件。风险很高,我不知道php。
我想添加一个兄弟div。这是默认的示例代码。
<div class="div1">
<div class="div1inside">
Text
</div>
</div>
<div class="div2">
<div class="div2inside">
Text
</div>
</div>
现在我想在div1和div2之间添加我的自定义div及其内部html。
<div class="mydiv">
<div class="mydivinside">
Text
</div>
</div>
请告诉我如何使用Javascript。

有(至少)两种方式,第一种方式:
// document.querySelector() finds, and returns, the first element
// matching the supplied selector (or null, if no element is found):
var el1 = document.querySelector('.div1');
// here we create an adjacent element from the string of HTML,
// the 'afterend' argument states that this adjacent element
// follows the el1 node, rather than preceding it or appearing
// within:
el1.insertAdjacentHTML('afterend', '<div class="mydiv"><div class="mydivinside">Text</div></div>');
var div1 = document.querySelector('.div1');
div1.insertAdjacentHTML('afterend', '<div class="mydiv"><div class="mydivinside">Text</div></div>');
&#13;
<div class="div1">
<div class="div1inside">
Text
</div>
</div>
<div class="div2">
<div class="div2inside">
Text
</div>
</div>
&#13;
第二个是您首先创建要插入的<div>
,然后使用parentNode.insertBefore()
:
var htmlString = '<div class="mydiv "><div class="mydivinside">Text</div></div>',
// here we create a <div> element:
div = document.createElement('div'),
// we retrieve the element after which the new
// element should be inserted:
div1 = document.querySelector('.div1');
// assign the supplied HTML string to the innerHTML of the
// created element:
div.innerHTML = htmlString;
// and use parentNode.insertBefore to insert the desired element
// (the first argument) before the element identified in the
// second argument, which is the nextSibling of the found
// 'div1' element:
div1.parentNode.insertBefore(div.firstChild, div1.nextSibling);
var htmlString = '<div class="mydiv "><div class="mydivinside">Text</div></div>',
div = document.createElement('div'),
div1 = document.querySelector('.div1');
div.innerHTML = htmlString;
div1.parentNode.insertBefore(div.firstChild, div1.nextSibling);
&#13;
<div class="div1">
<div class="div1inside">
Text
</div>
</div>
<div class="div2">
<div class="div2inside">
Text
</div>
</div>
&#13;

使用Node#insertBefore
方法。
// create a div element
var div = document.createElement('div');
// set class name
div.className = 'mydiv';
// set html contents
div.innerHTML = ' <div class="mydivinside"> Text </div>';
// get .div2 element
var ele = document.querySelector('.div2');
// insert before the .div2 element by getting
// its parent node
ele.parentNode.insertBefore(div, ele);
<div class="div1">
<div class="div1inside">
Text
</div>
</div>
<div class="div2">
<div class="div2inside">
Text
</div>
</div>

你可以这样做吗?
var firstDiv = document.getElementById('div1');
firstDiv.parentNode.insertBefore(document.getElementById('new-div'), firstDiv.nextSibling);
但是,假设您的new-div
已经在dom中。
编辑:要动态创建new-div

你可以使用before方法在div1和div2之间追加一个div。这是一个例子:
$('.div2inside').before("<div class='mydiv'><div class='mydivinside'>Text</div></div>");
