我有一些非常简单的 javascript 可以在 Chrome 中正常工作。但是,有一些东西在 IE 和 Firefox 中不起作用。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;
}

我在几行不起作用的行旁边加上了星号。奇怪的是,ChangeCSSRule 函数作用于两条“颜色”线。有什么建议么?

在 javascript 中更改 CSS 属性时,您需要对它们进行驼峰式处理,例如:background-color 变为 backgroundColor,background-image 变为 backgroundImage。
