jquery cfml trigger（'change'）不工作 [英] jquery cfml trigger('change') not working

问题描述

我需要的是绑定到列出文件类型的查询的cfselect，列出保存的文件的cfdiv，以及扫描图像以保存为PDF文件的按钮，其名称以输入值为前缀字段。

What I need is a cfselect bound to a query that lists file types, a cfdiv that lists the saved files, and a button that scans an image to be saved as a pdf file with the name prefixed by the value of the input field.

简单页面。

<cfselect name="DocType" id="DocType" class="selectClass" query="qGetDocTypes" display="name" value="DocTypeID">
<input name="ScanDocument" id="ScanDocument" type="text" value="" class="ScanDocument">

<cfdiv id="handler_#docAreaID#" bind="url:#request.controlurl#documentHandler/?docareaID=#docareaID#&variableID=#variableID#&Fav=#attributes.Fav#&userid=#attributes.userid#&showform=1&ScannedDocument={ScanDocument@change}">




// remove blanks from text
ScanDoc1 = $('input.scandocument').val();
ScanDoc = ScanDoc1.replace(/\s/g, '');
<cfoutput>
ColdFusion.navigate('url:#request.controlurl#documentHandler/?docareaID=#docareaID#&variableID=#variableID#&Fav=#attributes.Fav#&userid=#attributes.userid#&showform=1&ScannedDocument='+ScanDoc);
</cfoutput>

coldFusion.Navigate不会刷新CFdiv，它也会触发onBrowseAway的事件主要形式动作。我可以通过手动更改输入的值来模拟div刷新，但是在我得到这个工作后，它将被隐藏。

The coldFusion.Navigate does NOT refresh the CFdiv, and it also trigger an event for onBrowseAway I use for the main form action. I can simulate the div refresh by manually changing the value of the input but it will be hidden after I get this to work.

推荐答案

让我先介绍一下，我没有使用 ColdFusion.navigate 功能之前，但根据这里的文档该函数需要是一个链接目标。它需要在 a 标记的 href 部分中。看看我引用的文档页面上的示例。因此，尝试将您的代码添加到 a 标签，如下所示：

Let me preface this by stating that I have not used the ColdFusion.navigate functionality before but according to the documentation here the function needs to be a link target. It needs to be in the href portion of an a tag. Look at the example on the documentation page that I referenced. So try adding your code to an a tag like this:

<cfoutput>
<a href="javascript:ColdFusion.navigate('#request.controlurl#documentHandler/?docareaID=#docareaID#&variableID=#variableID#&Fav=#attributes.Fav#&userid=#attributes.userid#&showform=1&ScannedDocument='+ScanDoc,'handler_#docAreaID#');">click here</a>
</cfoutput>

请注意，我删除了 url：从您的代码。这似乎没有必要。

Notice that I removed the url: text from your code. That does not appear to be necessary.

它也出现了，因为你缺少函数的容器参数。该文档声明，如果您缺少此参数，链接将被视为正常的URL，整个页面将被刷新。 （虽然你的代码不是一个链接？）

It also appeared as though you are missing the container parameter for the function. The documentation states that if you are missing this parameter the link will be treated as a normal URL and the entire page will be refreshed. (Although your code was not a link?)

此外，我不知道你是否可以像函数一样引用函数的URL中的ColdFusion变量。这些是服务器端的，这个功能是客户端（javascript）。就像我说的，我从来没有使用过这些，但这些是我的阅读文档后的想法。

Also, I'm not sure if you can reference the ColdFusion variables in the URL of the function like you are. Those are server-side and this function is client-side (javascript). Like I said, I have never used this before but these are my thoughts after reading that documentation.
