javascript div背景图片
div如下：
6501f6ca163bee15a674f5d3b0943dae
16b28748ea4df4d9c2150843fecfba68
javascript方法:
function changeImg(obj){
obj.style.backgroundImage = "url(img/yygk1.png)";
//obj.style.backgroundImg = "url(img/yygk1.png)";
//obj.style.background = "url(img/yygk1.png)";
}
div原本是有背景图片的，当鼠标移动到div上的时，期望改变背景图片为yygk1.png,但实际运行结果是背景图片没了，这是怎么回事呢？
回复讨论(解决方案)
测试了一下，LZ的代码很好用啊。
测试的时候DIV本没有图片。鼠标移动到上面就显示了。
没什么问题
背景图片的 url 正确不？

obj.style.backgroundImage = "url(img/yygk1.png)";

}

你要保证背景图片路径正确才行

你要保证背景图片路径正确才行 这个url在哪里定义呢？我还以为这是个关键字呢，难道它只是个变量？
$(function(){
$("div").onmouseover(function(){
$(this).css("background-image","img/yygk1.png")
})
})
我比较习惯用JQuery 写,图片路径要正确,在同一级目录下可以直接写文件夹的名称,上一级就得用../

不需要定义，LZ写的URL正确
又测试了一次，可以正确执行。

不是的，晕死，你懂不懂CSS的基本知识啊，url(img/yygk1.png)，能去了解一下基本的知识么？

我也测了一下，不过要先将3f1c4e4b6b16bbbd69b2ee476dc4f83a中的2个0c6dc11e160d3b678d68754cc175188a标签改到6c04bd5ca3fcae76e30b72ad730ca86d标签中才可行，否则会报js异常。如下：
