Question

目前我随时添加评论。它将注释添加到数据库，但冻结了我所拥有的按钮，因此它们不起作用。虽然如果我刷新页面，他们会再次工作。添加评论后是否有办法让页面刷新。目前以下是我的代码。

<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
        <title>
            Untitled Document
        </title>

        <cfquery datasource="AccessTest" name="qTest">
            SELECT P.Account, P.Image, P.Image_ID, C.Remarks, C.Users, C.Accounts, C.Date_Time
            FROM PictureDB AS P
            INNER JOIN CommentsDB AS C
            ON C.Image_ID = P.Image_ID
            ORDER BY P.Image_ID
        </cfquery>

        <script src="http://code.jquery.com/jquery-2.0.3.js">

        </script>

        <script>
            $(document).ready(function(){
                  var images = {
                    <cfoutput query="qTest" group="Image_ID">
                        "#qTest.Image_ID#": {
                            "image": "#qTest.Image#",

                            </cfoutput>
                            ]
                        },
                    </cfoutput>
                };
                  $("button").click(function(event){
                    event.preventDefault();
                    var id = $(this).data("id");
                    var src = images[id].image;
                    var desc = images[id].remarks.toString();

                    $("#theImage").attr("src", src).removeClass("hide");
                    $("#theDescription").html(desc).removeClass("hide");

你以前没有发过这个代码吗？

为什么不在执行查询后再执行<cflocation>？这样，用户不会刷新并重新提交表单，它也可以解决您的问题。

<cfif IsDefined("form.InsertComments")>
      <cfquery datasource="AccessTest">
            INSERT INTO CommentsDB (Remarks, Image_ID, Date_Time )
            VALUES
                 (
                    <cfqueryparam value="#form.Remarks#" cfsqltype="CF_SQL_LONGVARCHAR">
                    ,<cfqueryparam value="#form.Image_ID#" cfsqltype="cf_sql_integer">
                    ,<cfqueryparam value="#now()#" cfsqltype="cf_sql_timestamp">
                 )
      </cfquery>
      <cflocation url="URL OF PAGE" addToken="false" />
</cfif>
