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
虽然其他答案在这里工作，我注意到您要求一个div与内容。所以这是我的版本，有额外的内容。JSFiddle链接在底部。
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:
<body>
<h1>Title</h1>
<p>This is a paragraph. Well, kind of.</p>
</body>
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:CSS线条借用Ratal Tomal

其他回答
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。
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。
这个解决方案使用jquery库
$('#elementId').append("<div class='classname'>content</div>");
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>
