OnMouseOver功能不起作用

Question

我制作了带有社交链接的图片的图片地图。但是，当我将链接更改为在新窗口中打开时，我丢失了我的OnMouseOver游标。顺便说一句，这全是在JavaScript中。我试图把它放进去，但它似乎并没有在任何地方工作。当我点击图像时，它们会进入一个新窗口，但光标不会改变，因此用户不知道它们在链接上。代码如下。

任何关于如何恢复的想法都会很棒。谢谢！

document.getElementById('topdiv').innerHTML = "<img border=\"0\" style=\"padding-right: 10px;\" src=\"../images/social_hor.png\" usemap=\"#socialmap\"><map name=\"socialmap\"><area shape=\"rect\" coords=\"320,0,365,50\" onClick=\"window.open('https://www.facebook.com/NCHSoftware')\" OnMouseOver='this.style.cursor='pointer';'><area shape=\"rect\" coords=\"375,0,420,50\" onClick=\"window.open('https://plus.google.com/+nchsoftware')\"><area shape=\"rect\" coords=\"425,0,470,50\" onClick=\"window.open('https://twitter.com/nchsoftware')\">"

所以我翻译这，你在你的问题贴太可怕了线（我想这就是为什么人们没有给你任何问题考虑），我想出了这个例子给你，当然你仍然需要在页面中正确实现它。

CSS

myImage { 
    padding-right: 10px; 
} 

HTML

<div id="topdiv"></div> 

的Javascript

var topdiv = document.getElementById('topdiv'), 
    map, 
    tempVar; 

function area1() { 
    alert("you clicked in area1"); 
} 

function area2() { 
    alert("you clicked in area2"); 
} 

function area3() { 
    alert("you clicked in area3"); 
} 

function pointerOn(evt) { 
    evt.target.style.cursor = "hand"; 
} 

function pointerOff(evt) { 
    evt.target.style.cursor = "auto"; 
} 

map = document.createElement("map"); 
map.name = "socialmap"; 

tempVar = document.createElement("area"); 
tempVar.shape = "rect"; 
tempVar.coords = "0,0,99,50"; 
tempVar.href = "#"; 
tempVar.addEventListener("click", area1, false); 
tempVar.addEventListener("mouseover", pointerOn, false); 
tempVar.addEventListener("mouseout", pointerOff, false); 
map.appendChild(tempVar); 

tempVar = document.createElement("area"); 
tempVar.shape = "rect"; 
tempVar.coords = "100,0,199,50"; 
tempVar.href = "#"; 
tempVar.addEventListener("click", area2, false); 
tempVar.addEventListener("mouseover", pointerOn, false); 
tempVar.addEventListener("mouseout", pointerOff, false); 
map.appendChild(tempVar); 

tempVar = document.createElement("area"); 
tempVar.shape = "rect"; 
tempVar.coords = "200,0,299,50"; 
tempVar.href = "#"; 
tempVar.addEventListener("click", area3, false); 
tempVar.addEventListener("mouseover", pointerOn, false); 
tempVar.addEventListener("mouseout", pointerOff, false); 
map.appendChild(tempVar); 

topdiv.appendChild(map); 

tempVar = document.createElement("img"); 
tempVar.className = "myImage"; 
tempVar.src = "http://i860.photobucket.com/albums/ab165/ATnightshift/image001.gif"; 
tempVar.useMap = "#socialmap"; 
topdiv.appendChild(tempVar);
