How to dynamically create and remove divs in js_javascript skills

The example in this article describes the method of dynamically creating and removing divs in js. Share it with everyone for your reference. The specific implementation method is as follows:

//创建div
function createDiv(){
 if(document.getElementByIdx_x("newD")!=null)
  document.body.removeChild(document.getElementByIdx_x("newD"));
 var Div = document.create_rElement("div");//创建div
 Div.setAttribute("id", "newD");
 Div.style.position = "absolute";
 Div.style.height = "160px";
 Div.style.width = "400px";
 Div.style.border = "1px solid grey";
 Div.style.background = "white";
 Div.style.paddingTop = "40px";
 Div.style.zIndex = "100";
 Div.style.left = 100 +"px";//注意Firefox下必须加"px"
 Div.style.top = 100 +"px";
 Div.style.textAlign = "center";
 Div.style.fontSize = "18px";
 var str = "<div id=\"divClose\" onclick=\"removeDiv()\" style=\"width:16px;height:16px;float:right;margin-top:-40px;background:url(images/divClose.gif);\"><\/div>";
 Div.innerHTML = str + title;
 document.body.appendChild(newD);
}
//移除创建的div
function removeDiv(){
 document.body.removeChild(document.getElementByIdx_x_x("newD"));
}

I hope this article will be helpful to everyone’s JavaScript programming design.
