句法？单击元素时将字符串变量设置为字符串值

$('#Colors span').live('click', function(){
    var layerFind = "BACK";

    if ($(this).hasClass('.CI_W')) {
        layerFind = "WHITE";
    } else if ($(this).hasClass('.CI_U')) {
        layerFind = "BLUE";
    } else {
        layerFind = "BASE";
    }       

    $("#Base").attr("src", 'Layers/' + layerFind + '.png');
});

我有代表颜色的图标的跨度。当用户单击该图标时，字符串变量 layerFind 会更改为适当的颜色。然后将该字符串用作图像文件的 src。目前它适用于 BASE 字符串值，这是我加载页面时的默认值，但它不响应跨度单击。

我想知道 switch 语句是否更有意义。稍后我将需要这个脚本来组合单击的颜色。例如，如果我单击白色图标和黑色图标，则字符串变为 WB，缩写，并且具有该名称的图像文件是灰色图像。如果我单击 3 个或更多，那么它会使用辅助默认值，例如 RAINBOW 等。

$('#Colors span').live('click', function(){
    var layerFind = "BACK";

    if ($(this).hasClass('.CI_W')) {
        layerFind = "WHITE";
    } else if ($(this).hasClass('.CI_U')) {
        layerFind = "BLUE";
    } else {
        layerFind = "BASE";
    }       

    $("#Base").attr("src", 'Layers/' + layerFind + '.png');
});

I have spans that are icons that represent colors. When a user clicks the icon, the string variable layerFind changes to the appropriate color. This string is then used as the src for an image file. Currently it works for the BASE string value, that is the default when i load the page, but it doesn't respond to the span clicks.

I'm wondering if a switch statement makes more sense. Later on i will need this script to be able to combine the colors clicked. For example, if i click the white icon and the black icon, the string becomes WB, an abbreviation, and the image file with that name is a gray image. If i click 3 or more, then it uses a secondary default, for example, RAINBOW or something.
