html div 移除,js动态创建及移除div的方法
本文实例讲述了js动态创建及移除div的方法。分享给大家供大家参考。具体实现方法如下：
//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.innerHTML = str + title;
document.body.appendChild(newD);
}
//移除创建的div
function removeDiv(){
document.body.removeChild(document.getElementByIdx_x_x("newD"));
}
希望本文所述对大家的javascript程序设计有所帮助。
