jquery cfml trigger('change') not working

问题

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.

Simple page.

<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>

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.

回答1:

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>

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

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?)

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.

回答2:

$('input.ScanDocument').trigger('Change');

if I were to guess, I would say that the capital "C" is the problem. JavaScript is case-sensitive.
