如何使用JavaScript创建div并设置样式？

How can I use JavaScript to create and style (and append to the page) a div, with content? I know it's possible, but how?

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);

Use parent reference instead of document.body.

使用父引用而不是document.body。

Depends on how you're doing it. Pure javascript:

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);

Doing the same using jquery is embarrassingly easy:

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');

Cheers!

干杯!

this solution uses the jquery library

此解决方案使用jquery库

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

While other answers here work, I notice you asked for a div with content. So here's my version with extra content. JSFiddle link at the bottom.

虽然这里的其他答案有效，但我注意到你要求一个包含内容的div。所以这是我的版本与额外的内容。 JSFiddle链接在底部。

JavaScript (with comments):

JavaScript（带注释）：

// 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);

HTML:

HTML：

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

CSS:

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; }

Here's one solution that I'd use:

这是我使用的一个解决方案：

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

If you wanted the attribute and/or attribute values to be based on variables:

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>';

Then, to append to the body:

然后，附加到身体：

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

Easy as pie.

易如反掌。

You can create like this

你可以这样创建

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

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

Complete Runnable Snippet:

完整的Runnable片段：

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);

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

create div with id name

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);
}

add text to div

将文本添加到div

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

test code

测试代码

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

output

产量

this is paragraph 1
