我的CFC的JSON响应是retunring HTML代码 [英] JSON response from my CFC is retunring HTML code
问题描述
这里有一个奇怪的问题。我使用jquery调用CFC并返回一个字符串。我然后试图填充一个表单字段与该字符串。
I have a strange issue here. I am making a call to a CFC using jquery and returning a string. I am then trying to populate a form field with that string. For some reason, my response is including HTML code along with the query results.
以下是JSON响应在控制台中的显示效果：
Here is how the JSON response looks in the console:
> Gary Turner check_out.cfm:146 Successfully ran JSON, now changing
> input value check_out.cfm:149 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML
> 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <head>
> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
>
> </head> <body>
>
>
>
>
>
> </body>
> 274.00
这是我的JQUERY：
Here is my JQUERY:
<!---Populate Grand Total --->
<script>
function PopulateGrandTotal(){
// Populate the customer alert DIV based on the customer selection
console.log( $("#customer_checkout>option:selected").attr("Value") );
$.ajax({
url:'cfcs/grand_totalDIV.cfc?method=getTotal&returnformat=json',
//dataType: 'text',
data: { customer_checkout: $("#customer_checkout>option:selected").attr("Value") },
success: function(response) {
console.log('Successfully ran JSON, now changing input value');
$("#grand_total_due").val( response );
console.log(response);
},
error: function(response){
console.log('Error');
}
});
}
</script>
这是我的CFC：
<cffunction name="getTotal" access="remote" returntype="string">
<cfargument name="customer_checkout" type="any" required="true">
<!--- localize function variables --->
<cfset var dataDetail = "">
<cfquery name="dataDetail" datasource="#datasource#" >
select grand_total
from service_ticket
where company_name = <cfqueryparam value="#ARGUMENTS.customer_checkout#" cfsqltype="cf_sql_varchar">
</cfquery>
<cfoutput query="dataDetail">
<cfreturn dataDetail.grand_total>
</cfoutput>
</cffunction></cfcomponent>
这是我的表格：
<cfform id="form" name="form" method="post" action="signature_popup.cfm" >
<br><br>
<div align="center"><cfselect class="required" queryPosition="below" query="get_ticket" display="company_name" name="customer_checkout" id="customer_checkout" tabindex="0" onchange="PopulateGrandTotal();" ><option>---Make A Selection---</option></cfselect>
<br><br>
<div id="grant_totalDIV" >
<h2><label for="grand_total_due">Total Amount Due:</label><input type="text" name="grand_total_due" id="grand_total_due"> </h2>
</div>
<br>
推荐答案
您应该查看Application.cfc文件 - Application.cfm - 它可能是设置页眉/页脚值。查找可能提示您的onrequestend（）和Onrequest（）或onrequeststart（）。
You should look at your Application.cfc file - or Application.cfm - it is probably setting up header/footer values. Look for "onrequestend()" and "Onrequest()" or "onrequeststart()" - that might clue you in.
您可能还有一个自定义标签类型方法
You might also have a custom tag type approach in there -- something that wraps every request.
您的 returnType将需要设置为json ，否则您只需要输入274.00即可没有json包装。
Your returnType will need to be set to json - otherwise you just get "274.00" with no json wrappers.
要修复HTML，您必须检查CFC，而不是运行相关函数。或者，您可以在CFC的文件夹中使用单独的Application.cfc，完全排除这些功能。当你直接从代码（如createobject（））中访问你的CFC时，这样一个单独的Application.cfc不起作用 - 但是当它们是你的示例中的请求的基本模板时就可以播放。
To fix the HTML you have check for a CFC and not run the function in question. Alternately you can use a separate Application.cfc in the folder of your CFCs that excludes those functions altogether. Such a separate Application.cfc is not in play when you access your CFC's directly from code (as in createobject()) - but comes in to play when they are the base template for a request as in your example.
记住，你可以使用method = getTotal&等等 - 无需在控制台中解决此问题，直到您在浏览器中获得正确的结果。
Remember that you can test right from the browser using method=getTotal& etc. - no need to troubleshoot this in the console until you get the results correct in the browser.
