在IE或Firefox中不会改变的背景图像和颜色

Question

我有一些非常简单的javascript构建,在Chrome中运行良好.但是,有一些东西在IE和Firefox中无效.这是代码:

function updateColors(){
    ChangeCSSRule('background-color',color,2);
    ChangeCSSRule('color',textcolor,0);
    ChangeCSSRule('color',textcolor,1);
    ChangeCSSRule('background-image','url(borders/r_edge_'+imgcolor+'.png)',3);
    ChangeCSSRule('background-image','url(borders/l_edge_'+imgcolor+'.png)',4);
    ChangeCSSRule('background-image','url(borders/t_edge_'+imgcolor+'.png)',5);
    ChangeCSSRule('background-image','url(borders/b_edge_'+imgcolor+'.png)',6); 
}   

function ChangeCSSRule(xElement, xValue, value){
    var strCSS = 'cssRules';
    if(document.all){
        strCSS = 'rules';
    }
    document.styleSheets[0][strCSS][value].style[xElement] = xValue;
}

这是样式表:

.firstName {
   font-family: Verdana, Geneva, sans-serif;
   font-size: 20px;
   margin: 0px; 
}
.lastName {
   font-family: Verdana, Geneva, sans-serif;
   font-size: 25px;
   text-wrap: none;
   margin: 0px;
}
.bg {
   background-color: #ffffff;
}
.r_edge {
   background-image: url(borders/r_edge_white.png); 
   background-repeat: repeat-y;     
}
.l_edge {
   background-image: url(borders/l_edge_white.png); 
   background-repeat: repeat-y;
}
.t_edge {
   background-image: url(borders/t_edge_white.png); 
   background-repeat: repeat-x;
}
.b_edge {
   background-image: url(borders/b_edge_white.png); 
   background-repeat: repeat-x;
}
.right {
   text-align: right;
}

我把星号放在几行不起作用的旁边.奇怪的是,ChangeCSSRule函数适用于两条"颜色"线.有什么建议？

在javascript中更改CSS属性时,您需要使用它们来构造它们,例如:background-color变为backgroundColor,background-image变为backgroundImage.
