javascript - C# - 从代码隐藏中添加 javascript 函数

Question

DBDataSet.tblAdsDataTable dtAds = client.getAdsDate(ref errCode, AdsType, AdsSlot, Country);
        string ss = "";
        string aa = "";
        if (dtAds.Rows.Count > 0)
        {
            foreach (DBDataSet.tblAdsRow dr in dtAds)
            {
                DateTime date = dr.AdsDate;
                string AdsDate = date.ToString("dd/MM/yyyy");

                ss += '"' + AdsDate + '"' +",";  
                aa = ss.TrimEnd(','); // equal to "01/01/2018","02/01/2018"

                string jquery = "var naArray = ["+ aa +"];";;
                ClientScript.RegisterStartupScript(typeof(Page), "a key","<script>" + jquery + "</script>");
            }
        }

嗨，从上面的代码中，我想在代码后面添加 javascript，如 <script> var naArray = ["01/01/2018","02/01/2018"];</script> 。但是，当我执行时，它变成 <script> var naArray = ["01/01/2018"]; <script>数组中缺少“02/01/2018”。如果有人可以提供帮助，我们将不胜感激。谢谢。

您正在 foreach 循环内为 jquery 变量设置值。它应该在循环之外。尝试按如下方式更新您的代码。

DBDataSet.tblAdsDataTable dtAds = client.getAdsDate(ref errCode, AdsType, AdsSlot, Country);
string ss = "";
string aa = "";
if (dtAds.Rows.Count > 0)
{
    foreach (DBDataSet.tblAdsRow dr in dtAds)
    {
        DateTime date = dr.AdsDate;
        string AdsDate = date.ToString("dd/MM/yyyy");

        ss += '"' + AdsDate + '"' +",";                  
    }
    aa = ss.TrimEnd(','); // equal to "01/01/2018","02/01/2018"
    string jquery = "var naArray = ["+ aa +"];";;
    ClientScript.RegisterStartupScript(typeof(Page), "a key","<script>" + jquery + "</script>");
}
