推荐答案

尝试一下:

Try this:

var images = {
  0: 'images/pic1.png',
  1: 'images/pic2.png',
  2: 'images/pic3.png'
}

function setImage(elementId, imageIndex) {
  document.getElementById(elementId).src = images[imageIndex];
}

您可以使用类似于以下的代码创建阵列服务器端:

You can create the array server side using code similar to this:

string[] files = System.IO.Directory.GetFiles("d:\\picture");
        System.Text.StringBuilder sb = new StringBuilder();
        string relativePath = "images";
        int fileIndex = 0;
        sb.AppendLine("var images = {");
        foreach (string file in files)
        {
          System.IO.FileInfo fi = new FileInfo(file);
          sb.AppendLine((fileIndex > 0 ? "," : "") + fileIndex + ": '" + relativePath + "/" + fi.Name + "'");
        }
        sb.AppendLine("};");

        System.Web.UI.HtmlControls.HtmlGenericControl script = new System.Web.UI.HtmlControls.HtmlGenericControl("script");
        script.Attributes.Add("language", "javascript");
        script.Attributes.Add("type", "text/javascript");
        script.InnerText = sb.ToString();

        this.Controls.Add(script);
