var div = document.createElement("div"); Div.style.width = "100px"; Div.style.height = "100px"; Div.style.background = "red"; Div.style.color = "白色"; div.innerHTML = "Hello"; . getelementbyid(“主要”).appendChild (div); 身体< > < div id = "主" > < / div > 身体< / >

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。

我喜欢做的另一件事是创建一个对象，然后循环遍历对象并设置样式，因为逐个编写每个样式会很乏味。

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);

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< / >

创建id为name的div

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

向div添加文本

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

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!
