我的页面上有超链接
<a id="delete-file" href="">
<img border="0" src="images/delete_.png" alt="Delete File" width="20" height="20" />
</a>
我试图在单击时阻止默认操作并改为运行AJAX函数。出于某种原因,当我点击它时,它只是将我带到页面的顶部,我的AJAX没有被解雇。没有控制台错误消息。
有人可以用我的语法帮助我吗?

$(document).on("click","##delete-file",function(e){
ajaxDelete();
e.preventDefault();
});
尝试放置包含## delete-file(在DOM之前加载)的任何div,代替文档。
$(document).ready(function(){
$("#wrapper-div").on("click","##delete-file",function(e){
ajaxDelete();
e.preventDefault();
});
});
如果由于Cold Fusion而无法使用ID,请尝试在链接中添加一个类:
<a id="delete-file" href="" class="delete-btn">
然后尝试
$(document).ready(function(){
$(".delete-btn").on("click",function(e){
ajaxDelete();
e.preventDefault();
});
});

这是一个很长的镜头,但我认为问题是你没有逃脱所有的哈希标志。请注意您的网址:
url: "actionpages/delete_attachment.cfm?ticketID=#URL.ticket_id#&file_path=#filecheck.file_path#"
url: "actionpages/file_upload_action.cfm?ticket_id=#url.ticket_id#",
你正在逃避你的ID的哈希标志,但不是那里,所以我猜你的服务器正在改变你的Javascript,造成错误并阻止代码执行。你也应该尝试双击它们。
如果它确实是Id的问题,那么也许你可以像这样使用其他jQuery构造函数:
$(document.getElementById('delete-file'));

好的,所以我假设错误与我的AJAX调用失去了它们的唯一性有关,因为AJAX的代码在我之外是正确的。我基本上不得不调整我的代码,以便我的AJAX代码在我的标签内,但更重要的是,函数提供了唯一的名称,并从我的输出中传递了唯一的数据。
以下是我修改过的正确代码:
<cfoutput>
<table width="50%" border="0" cellpadding="5">
<tr bgcolor="##CCCCCC">
<td width="8%"> </td>
<td width="67%" ><strong>Filename</strong></td>
<td width="18%" ><strong>Actions</strong></td>
</tr>
<cfloop query="filecheck">
<tr bgcolor="###iif(currentrow MOD 2,DE('ffffff'),DE('efefef'))#" class="btnav" onmouseover="style.backgroundColor='##FFFFCC';"
onmouseout="style.backgroundColor='###iif(currentrow MOD 2,DE('ffffff'),DE('efefef'))#'">
<td><img src="images/Paper-Clip-icon.png" alt="Attachment" /><br /></td>
<td><a href="https://#subscriber.hostName#.#subscriber.baseURL#/ticket-uploads/#filecheck.file_path#" target="_blank">#filecheck.file_path#</a>
(Record-ID #ID#)
</td>
<td>
<a id="delete-file#ID#" class="delete-btn#ID#" href="">
<img border="0" src="images/delete_.png" alt="Delete File" width="20" height="20" />
</a>
<!---Script to upload file link --->
<script>
$(document).ready(function(){
$(".delete-btn#ID#").on("click",function(e){
// ajaxDelete();
console.log("Start of prevent.");
e.preventDefault();
console.log("Calling AJAX with id of #ID#.");
ajaxDelete#ID#();
});
function ajaxDelete#ID#() {
console.log("ajaxDelete function called");
$.ajax({
