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

这个解决方案使用jquery库

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

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

JSFiddle: https://jsfiddle.net/Rani_Kheir/erL7aowz/

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!
