How to dynamically create divs using Js

This article mainly introduces tips on deduplication or statistics of PHP two-dimensional arrays based on a certain field. It has a certain reference value. Now I share it with you. Friends in need can refer to it

This is the original CSS style

.item{float:left;overflow:hidden;margin-left:8px;margin-top:10px;width: 320px; height: 
250px;background-repeat: no-repeat; background-image:url(../images/bgred.jpg)} 
.curve{position:relative;width:320px; height:250px; z-index:1; left: 75px; top: -40px;}

The code for dynamically creating p is as follows:

for(j = 0;j*8 <str.length; j++) 
{ 
var myp = window.frames["displayFrame"].document.createElement("p"); 
myp.setAttribute("id","itemp"+j); 
myp.style.styleFloat="left"; 
myp.style.overflow="hidden"; 
myp.style.marginLeft="8px"; 
myp.style.marginTop="10px"; 
myp.style.width="320px"; 
myp.style.height="250px"; 
myp.style.backgroundRepeat="no-repeat"; 
myp.style.backgroundImage="url(image/bgred.jpg)" 
window.frames["displayFrame"].document.body.appendChild(myp); 
var curvep =window.frames["displayFrame"].document.createElement("p"); 
curvep.setAttribute("id","curvep"+j); 
curvep.style.position="relative"; 
curvep.style.zIndex=1; 
curvep.style.left="75px"; 
curvep.style.top="-40px"; 
curvep.style.width="320px"; 
curvep.style.height="250px"; 
window.frames["displayFrame"].document.getElementById("pitem"+j).appendChild(curvep); 
}

Add the p element to HTML.
You can also define one in HTML SPAN

window.frames["displayFrame"].document.getElementById("spanId").appendChild(myp); 
window.frames["displayFrame"].document.body.appendChild(myp);

Both IE and Firefox support it.
Another thing to note is this CSS element
Floating effect: float:left
The code under IE is: myp.style. styleFloat="left";
The code in Firefox is: myp.style.cssFloat="left";
Other elements such as this:
In CSS writing, it is usually: margin-left:8px
And when adding dynamically, it needs to be removed - :myp.style.marginLeft="8px";
There is no careful study on the case sensitivity issue.
