我试图从C#多次调用JavaScript函数,但它只执行一次。从不同参数的C#多次调用javascript函数

这里是我的C#代码

DataTable table = new DataTable(); 
       string data = " * "; 
       string fromTable = " Decoration "; 

       table = SqlHelper.LoadMyTableData(data, fromTable); 

       int i = 0; 
       foreach (DataRow row in table.Rows) 
       { 
        string id = row["DecrationID"].ToString(); 
        string name = row["DecorationName"].ToString(); 
        string details = row["DecorationDetails"].ToString(); 
        string servicesOffered = row["ServicesOffered"].ToString(); 
        string imagePath = row["DecorationImagePath"].ToString(); 

        //ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text", "Func('" + id + "')", true); 
        string scriptKey = "text" + id; 
        ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text5", "populateDecor('" + id + "','" + name + "','" + details + "','" + servicesOffered + "', '" + imagePath + "')", true); 
        i++; 
       } 

JavaScript函数

<script type="text/javascript" > 
     function populateDecor(id, name, details, servicesOffered, imagePath) { 

      alert(name); 

      var text = "<div class=\"row ae__dec-details__item\">"; 
      text += " <div class=\"col-md-10\">"; 
      text += " <div class=\"media\">"; 
      text += "<div class=\"media-left\"> <a href=\"#\"> <img src=\"" + imagePath + "\" width=\"200\" alt=\"...\" class=\"media-object\" /></a> </div>"; 
      text += "<div class=\"media-body\">"; 
      text += "<h3 class=\"media-heading\">" + name + "</h3>"; 

      text += "<label>" + servicesOffered + "</label>"; 
      text += "<p>" + details + "</p>"; 
      text += "</div> </div> </div>"; 
      text += "<div class=\"col-md-2 ae__dec-details__ca\">"; 
      text += "<a href=\"EventSketch-decorEdit.aspx?dp=" + id + "\" style=\"color:cornflowerblue; background-color:white; margin-bottom:5px\" class=\"ae__btn\">Edit</a>"; 
      text += "<a href=\"EventSketch-decor-confirmPackage.aspx?dp=" + id + "\" class=\"ae__btn\">Select</a>"; 
      text += "</div> </div>"; 

      $(".col-md-12").append(text); 

     } 
</script> 

我有不同的脚本键尝试它。但仍然只有第一个记录被附加在div中。

在此先感谢。

可以传递只有4个参数是这样'ScriptManager.RegisterStartupScript(Page.GetType(), “text5”, “populateDecor('” +编号+ “ ''” +名字+“”注册脚本,'+ details +'','“+ servicesOffered +”','“+ imagePath +”')“,true);' –

你会在浏览器控制台上发现任何js错误吗? –

你可以试试这个:你需要在调用finction结束时添加;

DataTable table = new DataTable(); 
       string data = " * "; 
       string fromTable = " Decoration "; 

       table = SqlHelper.LoadMyTableData(data, fromTable); 

       int i = 0; 
       foreach (DataRow row in table.Rows) 
       { 
        string id = row["DecrationID"].ToString(); 
        string name = row["DecorationName"].ToString(); 
        string details = row["DecorationDetails"].ToString(); 
        string servicesOffered = row["ServicesOffered"].ToString(); 
        string imagePath = row["DecorationImagePath"].ToString(); 

        //ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text", "Func('" + id + "')", true); 
        string scriptKey = "text" + id; 
        ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text5", "populateDecor('" + id + "','" + name + "','" + details + "','" + servicesOffered + "', '" + imagePath + "');", true); 
        i++; 
       }

我建议轻松解决这个问题。我们建议使用文字进行此类操作。添加文字元素之前,添加到页面的底部。我添加了asp.net文字和javascript示例。

Default.aspx的

<body> 
<form id="form1" runat="server"> 
    <div> 

    </div> 

</form> 
<asp:Literal ID="ltrMessage" runat="server"></asp:Literal> 

Default.aspx.cs

 protected void Page_Load(object sender, EventArgs e) 
    { 
     ltrMessage.Text="<script>alert('OK')</script>"; 
    } 

希望它能帮助。

从您的代码,看来,你已经通过了关键 PARAM为硬编码(如text5),错过了分号调用函数一样@Bharatsing说,他的回答结束。

在代码中替换下面的任何行并尝试。希望它可以帮助你..

ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text"+ i, "populateDecor('" + id + "','" + name + "','" + details + "','" + servicesOffered + "', '" + imagePath + "');", true); 

OR

注:对于这个ID应该是所有行唯一那么只有它才能正常工作。

ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text"+ id, "populateDecor('" + id + "','" + name + "','" + details + "','" + servicesOffered + "', '" + imagePath + "');", true);
