如何在jquery选项卡单击功能中调用coldfusion查询
我写了一个jquery函数。嗯，调用 Coldfusion 查询来动态地将元素附加到垃圾邮件中，但这不起作用。谁能告诉我出了什么问题吗？
$('a.clikceble',$this).click(function(){
<cfloop query="GET_ALL_STUDENT_INFO_QUERY">
alert("inside");
$(".quick_time_dl a").attr("href", "index.cfm?event=location.index§ion=download&topic_id=<cfoutput>#URLDecode(url.topic_id)#</cfoutput>&video_id=<cfoutput>#URLDecode(url.video_id)#</cfoutput>&video_name=<cfoutput>#URLDecode(url_mov)#</cfoutput>&video_type=lif_mov");
$(".win_media_dl a").attr("href", "index.cfm?event=location.index§ion=download&topic_id=<cfoutput>#URLDecode(url.topic_id)#</cfoutput>&video_id=<cfoutput>#URLDecode(url.video_id)#</cfoutput>&video_name=<cfoutput>#URLDecode(url_wmv)#</cfoutput>&video_type=lif_wmv");
<cfif len(url_pdf)>
$("#url_pdf").attr("href", "../assets/teaching_notes_pdf/<cfoutput>#URLDecode(url_pdf)#</cfoutput>");
$(".pdf_desc").append($("#url_pdf"));
alert($(".pdf_desc").append($("#url_pdf")));
$("#url_pdf").show();
</cfif>
<cfif len(pdf_transcript)>
$("#pdf_transaction").attr("href", "../assets/teaching_notes_transcripts/<cfoutput>#URLDecode(pdf_transcript)#</cfoutput>");
$(".pdf_desc").append($("#pdf_transaction"));
alert($(".pdf_desc").append($("#pdf_transaction")));
$("pdf_transaction").show();
</cfif>
</cfloop>
I wrote a jquery function . um calling to a coldfusion query to dynamically append elements to a spam but this is not working . can any one tell what s wrong?
$('a.clikceble',$this).click(function(){
<cfloop query="GET_ALL_STUDENT_INFO_QUERY">
alert("inside");
$(".quick_time_dl a").attr("href", "index.cfm?event=location.index§ion=download&topic_id=<cfoutput>#URLDecode(url.topic_id)#</cfoutput>&video_id=<cfoutput>#URLDecode(url.video_id)#</cfoutput>&video_name=<cfoutput>#URLDecode(url_mov)#</cfoutput>&video_type=lif_mov");
$(".win_media_dl a").attr("href", "index.cfm?event=location.index§ion=download&topic_id=<cfoutput>#URLDecode(url.topic_id)#</cfoutput>&video_id=<cfoutput>#URLDecode(url.video_id)#</cfoutput>&video_name=<cfoutput>#URLDecode(url_wmv)#</cfoutput>&video_type=lif_wmv");
<cfif len(url_pdf)>
$("#url_pdf").attr("href", "../assets/teaching_notes_pdf/<cfoutput>#URLDecode(url_pdf)#</cfoutput>");
$(".pdf_desc").append($("#url_pdf"));
alert($(".pdf_desc").append($("#url_pdf")));
$("#url_pdf").show();
</cfif>
<cfif len(pdf_transcript)>
$("#pdf_transaction").attr("href", "../assets/teaching_notes_transcripts/<cfoutput>#URLDecode(pdf_transcript)#</cfoutput>");
$(".pdf_desc").append($("#pdf_transaction"));
alert($(".pdf_desc").append($("#pdf_transaction")));
$("pdf_transaction").show();
</cfif>

最好的方法是，当您单击选项卡时，通过 ajax 方法调用 Coldfusion 页面。只需使用查询创建一个 Coldfusion 页面，并通过 JSON 格式返回结果。您可以将 jquery ajax 函数与 json 数据类型一起使用，然后循环结果集，最后将其附加到 DOM。对“jquery Coldfusion”进行简单的谷歌搜索会返回大量结果，例如“使用 ColdFusion、jQuery 和 CFC 的轻松 AJAX"。
The best way to do this, when you click your tab, call your coldfusion page via ajax method. Just create a coldfusion page with the query, and returs the results via JSON format. You can use jquery ajax function with json data type, then loop over your result set and finally append it to your DOM. A simple google search for 'jquery coldfusion' returns lot of results, such as "Easy AJAX using ColdFusion, jQuery and CFCs".
在此代码中，首先将执行服务器端代码（cfloop、cfif 等）并创建客户端 java 脚本。在您的情况下，如果查询（GET_ALL_STUDENT_INFO_QUERY）有3条记录，那么在处理服务器端之后，它将创建脚本三次并将其返回到浏览器，但它不会在点击事件中处理任何查询操作（服务器端代码）。要处理单击事件（来自客户端）的服务器端操作，您需要使用 Ajax。
In this code, first the server side code will execute(the cfloop, cfif,etc.) and will create the client side java script. IN your case if the query(GET_ALL_STUDENT_INFO_QUERY) has 3 records then after processing the server side it will create the script three times and return it to the browser, but it will not processes any query operation(server side code) at the click event. To processes a server side operation on the click event(from the client side) you need to use the Ajax.
