我如何使用JavaScript创建和风格(并追加到页面)一个div，与内容? 我知道这是可能的，但怎么做呢?
当前回答
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。

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< / >
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。
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);
你可以使用下面的方法:
document.write()
这是非常简单的，在下面的文件我解释
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>
