Question

如何使用JavaScript创建和设置（并附加到页面）包含内容的div？我知道这是可能的，但是怎么样？

Answer 1

var div = document.createElement("div");
div.style.width = "100px";
div.style.height = "100px";
div.style.background = "red";
div.style.color = "white";
div.innerHTML = "Hello";

document.getElementById("main").appendChild(div);

<body>
<div id="main"></div>
</body>

var div = document.createElement("div");
div.style.width = "100px";
div.style.height = "100px";
div.style.background = "red";
div.style.color = "white";
div.innerHTML = "Hello";

document.getElementById("main").appendChild(div);
OR
document.body.appendChild(div);

使用父引用而不是document.body。

Answer 2

取决于你是如何做到的。纯javascript：

var div = document.createElement('div');
div.innerHTML = "my <b>new</b> skill - <large>DOM maniuplation!</large>";
// set style
div.style.color = 'red';
// better to use CSS though - just set class
div.setAttribute('class', 'myclass'); // and make sure myclass has some styles in css
document.body.appendChild(div);

使用jquery做同样的事情很容易：

$('body')
.append('my DOM manupulation skills dont seem like a big deal when using jquery')
.css('color', 'red').addClass('myclass');

干杯！

Answer 3

此解决方案使用jquery库

$('#elementId').append("<div class='classname'>content</div>");

Answer 4

虽然此处的其他答案有效，但我注意到您要求提供内容的div。所以这是我的版本与额外的内容。 JSFiddle链接在底部。

JavaScript （带评论） ：

// Creating a div element
var divElement = document.createElement("Div");
divElement.id = "divID";

// Styling it
divElement.style.textAlign = "center";
divElement.style.fontWeight = "bold";
divElement.style.fontSize = "smaller";
divElement.style.paddingTop = "15px";

// Adding a paragraph to it
var paragraph = document.createElement("P");
var text = document.createTextNode("Another paragraph, yay! This one will be styled different from the rest since we styled the DIV we specifically created.");
paragraph.appendChild(text);
divElement.appendChild(paragraph);

// Adding a button, cause why not!
var button = document.createElement("Button");
var textForButton = document.createTextNode("Release the alert");
button.appendChild(textForButton);
button.addEventListener("click", function(){
    alert("Hi!");
});
divElement.appendChild(button);

// Appending the div element to body
document.getElementsByTagName("body")[0].appendChild(divElement);

<强> HTML：

<body>
  <h1>Title</h1>
  <p>This is a paragraph. Well, kind of.</p>
</body>

<强> CSS：

h1 { color: #333333; font-family: 'Bitter', serif; font-size: 50px; font-weight: normal; line-height: 54px; margin: 0 0 54px; }

p { color: #333333; font-family: Georgia, serif; font-size: 18px; line-height: 28px; margin: 0 0 28px; }

注意：从Ratal Tomal借来的CSS行

Answer 5

以下是我使用的解决方案之一：

var div = '<div id="yourId" class="yourClass" yourAttribute="yourAttributeValue">blah</div>';

如果您希望属性和/或属性值基于变量：

var id = "hello";
var classAttr = "class";
var div = '<div id='+id+' '+classAttr+'="world" >Blah</div>';

然后，附加到身体：

document.getElementsByTagName("body").innerHTML = div;

很容易就是馅饼。

Answer 6

您可以像这样创建

board.style.cssText = "position:fixed;height:100px;width:100px;background:#ddd;"

document.getElementById("main").appendChild(board);

完整的Runnable片段：

＆＃13;

var board;
board= document.createElement("div");
board.id = "mainBoard";
board.style.cssText = "position:fixed;height:100px;width:100px;background:#ddd;"
    
document.getElementById("main").appendChild(board);

＆＃13;

<body>
<div id="main"></div>
</body>

＆＃13;

Answer 7

使用id名称

创建div

var divCreator=function (id){
newElement=document.createElement("div");
newNode=document.body.appendChild(newElement);
newNode.setAttribute("id",id);
}

将文字添加到div

var textAdder = function(id, text) {
target = document.getElementById(id)
target.appendChild(document.createTextNode(text));
}

测试代码

divCreator("div1");
textAdder("div1", "this is paragraph 1");

输出

this is paragraph 1

Answer 8

这将在具有自定义CSS且类名称为Custom的函数或脚本标记内

 var board = document.createElement('div');
 board.className = "Custom";
 board.innerHTML = "your data";
 console.log(count);
 document.getElementById('notification').appendChild(board);

Answer 9

我想做的另一件事是创建一个对象，然后循环遍历该对象并设置类似的样式，因为这样可能会很乏味地逐个编写每个样式。

var bookStyles = {
   color: "red",
   backgroundColor: "blue",
   height: "300px",
   width: "200px"
};

let div = document.createElement("div");

for (let style in bookStyles) {
 div.style[style] = bookStyles[style];
}

body.appendChild(div);

Answer 10

您可以使用以下方法：

document.write()

很简单，我在下面的文档中解释

document.write("<div class='div'>Some content inside the div (It is styled!)</div>")

.div {
  background-color: red;
  padding: 5px;
  color: #fff;
  font-family: Arial;
  cursor: pointer;
}

.div:hover {
  background-color: blue;
  padding: 10px;
}

.div:hover:before {
  content: 'Hover! ';
}

.div:active {
  background-color: green;
  padding: 15px;
}

.div:active:after {
  content: ' Active! or clicked...';
}

<p>Below or above well show the div</p>
<p>Try pointing hover it and clicking on it. Those are tha styles aplayed. The text and background color changes.</p>
