使用JavaScript将DOM元素添加到Body的最佳方法 [英] Best way to add DOM Element to Body with JavaScript
问题描述
我需要在每个页面放置此代码:
I need to put at every page this code:
document.body.innerHTML += '<div style="position:fixed; text-align:center; left:30px; widht: 200px;bottom: -12px;"> <div class="card" style="position: relative;background: #EC2D2D;border-radius: 5px;padding: 20px 0 0px 0;box-sizing: border-box;box-shadow: 0 2px 4px rgba(0, 0, 0, 0.12), 0 1px 3px rgba(0, 0, 0, 0.24);-webkit-transition: .3s ease;transition: .3s ease;"> <h1 class="title" style="position: relative;z-index: 1;border-left: 5px solid #FFFFFF;margin: 0 0 25px;padding: 10px 0 10px 10px;color: #FFFFFF;font-size: 32px;font-weight: 600;/* text-transform: uppercase; */">50% less</h1> <div class="button-container" style="margin: 0 20px;text-align: center;"> <button style="outline: 0;cursor: pointer;position: relative;display: inline-block;background: 0;color: #EC2D2D;background: #fff;width: 170px;border: 2px solid #C70A0A; padding: 10px 0;font-size: 14px;font-weight: 600;line-height: 1;text-transform: uppercase;overflow: hidden;-webkit-transition: .3s ease;transition: .3s ease;"><span>Bid and Book Now</span></button> </div> <div class="footer" style="margin: 20px 0 0;color: #FFFFFF !important;font-size: 14px;font-weight: 100;text-align: center;"> <p style="color: inherit;text-decoration: none;-webkit-transition: .3s ease;transition: .3s ease;">BEST RATES - only on website</p> <p style="font-size: 10px;">End in: 1d 2h 33m</p></div> </div> <div class="card alt" style="position: absolute;top: 40px;border: 3px solid #ED2553;right: -40px;z-index: 10;width: 80px;height: 80px;background: #FFFFFF;background-image: url("http://i.imgur.com/32T7CPH.jpg");border-radius: 100%;box-shadow: none;padding: 0;-webkit-transition: .3s ease;transition: .3s ease;"> </div> </div> ';
此代码在每个页面都不能正常工作。此外,我认为它非常慢并且对某些页面造成问题。如何用 appendChild
或类似的东西来写这个?
This code doesn't work well at every page. Also, I think its very slow and makes problem for some pages. How can I write this with appendChild
or something similar?
我不能使用JQuery的 append
因为我必须使用普通的JavaScript代码。
I can't use JQuery's append
because I have to use plain JavaScript code.
使用 appendChild $这段代码会是什么样子? c $ c>?
推荐答案
方法 appendChild
take节点并将此节点添加到调用它的元素。
The method appendChild
take a node and add this node to the element on which it was called.
var node = document.createElement("DIV");
var textNode = document.createTextNode("My Div content");
node.appendChild(textNode);
document.body.appendChild(node);
你不能使用 appendChild
包含整个html的字符串。
You can't use appendChild
with a string containing the whole html.
您可以做的是创建一个节点。使用巨大的字符串设置 innerHTML
。然后将节点附加到正文。
What you can do is create a node. Set its innerHTML
with the huge string. Then append the node to the body.
代码应与此类似:
var content = ....
var newNode = document.createElement("DIV");
newNode.innerHTML = content;
document.body.appendChild(newNode);
