这是显示的内容：
public string GetGift(int PageSize, int PageIndex)
{
GeneralConfigInfo config = GeneralConfigs.GetConfig();
OnlineUserInfo oluserinfo = OnlineUsers.UpdateInfo(config.Passwordkey, config.Onlinetimeout);
string username = oluserinfo.Username;
StringBuilder HtmlBuilder = new StringBuilder();
List<Exchange> ListExchange = ExchangeHelper.GetExchange(PageSize, PageIndex);

for (int i = 0; i < ListExchange.Count; i = i + 2)
{
HtmlBuilder.AppendLine("<div class=\"rightItem\">");

HtmlBuilder.AppendLine("<div class=\"rightSubItem\">");
HtmlBuilder.AppendLine("<div class=\"subItemImg\"><img src=\"" + ListExchange[i].ExchangeSmallPic + "\" /></div>");
HtmlBuilder.AppendLine("<div class=\"subItemTxtArea\">");
HtmlBuilder.AppendLine("<p class=\"subItemTitle\">"+ListExchange[i].ExchangProduct+"</p>");
HtmlBuilder.AppendLine("<div class=\"subItemContent\">");
HtmlBuilder.AppendLine("<p class=\"subItemIntro\">会员换购价：</p>");
HtmlBuilder.AppendLine("<p class=\"subItemPrice\"><font style=\"font-size:20px; font-family:Arial, Helvetica, sans-serif\">" + ListExchange[i].BeanCount.ToString().Trim() + "</font>  乐豆</p>");
HtmlBuilder.AppendLine("<p class=\"subItemCount\">仅剩 "+ListExchange[i].ExchangeCount.ToString()+" 件</p>");
HtmlBuilder.AppendLine("</div>");
HtmlBuilder.AppendLine("<p class=\"subItemBtn\"><a onclick=\"gift(" + username + "," + Countintegral.Sum(oluserinfo.Userid) + "," + ListExchange[i].BeanCount.ToString().Trim() + "," + ListExchange[i].ExchangeId + ")\"><img src=\"images/giftExchange_btn.jpg\" /></a></p>");
HtmlBuilder.AppendLine("</div>");
HtmlBuilder.AppendLine("</div>");



HtmlBuilder.AppendLine("</div>");
}
return HtmlBuilder.ToString();
}//红色部分是调用的js文件（点击图片无反应）
js文件:function gift(username, num,num2,url) {
if (username == "游客") {
alert("请先登陆");
}
else {
if (num < num2) {
alert("你的积分不够！");
}
else {
window.location.replace("exchange.aspx?exchangeid="+url);
}
}
}

HtmlBuilder.AppendLine("<p class=\"subItemBtn\"><a onclick=\"gift('" + username + "','" + Countintegral.Sum(oluserinfo.Userid) + "','" + ListExchange[i].BeanCount.ToString().Trim() + "','" + ListExchange[i].ExchangeId + "')\"><img src=\"images/giftExchange_btn.jpg\" /></a></p>");

加上单引号

[YISUKU_LEE]

onclick

a onclick=\"gift('" + username + "','"

需要单引号的。

HtmlBuilder.AppendLine("<p class=\"subItemBtn\" id=\"subItemBtn\"><a href=\" javascript:gift('" + username + "','" + Countintegral.Sum(oluserinfo.Userid) + "','" + ListExchange[i ].BeanCount.ToString().Trim() + "','" + ListExchange[i ].ExchangeId + "')\"/><img src=\"images/giftExchange_btn.jpg\"/> </a></p>");
