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
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< / >
其他回答
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。
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。
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
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

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