这将在一个自定义CSS的函数或脚本标记中，类名为custom

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

这将在一个自定义CSS的函数或脚本标记中，类名为custom

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

这里有一个我会使用的解决方案:

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

如果你想让属性和/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，附加到正文:

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

容易得很。

下面是一个小例子，它使用了一些漂亮的可重用DOM实用函数:

// DOM utility functions: const ELNew = (tag, prop) => Object.assign(document.createElement(tag), prop), ELS = (sel, par) => (par ?? document).querySelectorAll(sel), EL = (sel, par) => (par ?? document).querySelector(sel); // Task: const EL_new = ELNew("div", { className: "item", textContent: "Hello, World!", onclick() { console.log(this.textContent); }, style: ` font-size: 2em; color: brown; background: gold; ` }); // Append it EL("body").append(EL_new);

此外，你还可以使用Object.assign()对元素进行样式化，如下所示:

// Add additional styles later:
Object.assign(EL_new.style, {
  color: "red",
  background: "yellow",
  fontSize: "3rem",
});

这取决于你怎么做。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做同样的事情非常简单:

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

干杯!

你可以这样做

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

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

完整的可运行代码片段: var董事会; 董事会= document.createElement (" div "); 董事会。id = "主板"; board.style.cssText = "位置:固定;高度:100px;宽度:100px;背景:#ddd;" . getelementbyid(“主要”).appendChild(板); 身体< > < div id = "主" > < / div > 身体< / >
