ColdFusion Prefix serialized JSON with - json

Question

In the CF 2016 Administrator page, by selecting the check box "Prefix serialized JSON with" //ABC (form example), it will break the function below, because it will add the string //ABC to the JSON
How can we remove the prefix //ABC before parsing the JSON, please?
<cffunction name="searchData" access="remote" returnformat="JSON">
<cfquery name="getData" datasource="#dataSource#">
SELECT *
FROM aTable
</cfquery>
<cfreturn serializeJSON(getData)>
</cffunction>
Thank you for your help

We have an option for this prefix Serialized JSON uncheck the Prefix serialized JSON with options in our admin comes under the options cfadmin - > Server Settings - > setting table you can see that options. FYR, Please refer my below images & sample codes,
Before uncheck the prefix option:
<cfset struct = {"name":"thiraviam", "age":24}>
<cfdump var="#serializeJSON(struct)#">
Output:
//abc{"name":"thiraviam","age":24}
After uncheck the prefix option:
<cfset struct = {"name":"thiraviam", "age":24}>
<cfdump var="#serializeJSON(struct)#">
Output:
{"name":"thiraviam","age":24}

I hope it's help you more. Thank you !

You did not provide how you are calling this service. Regardless, all you need to do when calling a service which prefixes the JSON data is remove the prefixed data before processing the response. Below is an example using jQuery to make an AJAX call to such a service.
For jQuery AJAX the key for this is to use the dataFilter option. The dataFilter option gives you access to the raw response so it can be sanitized.
A function to be used to handle the raw response data of XMLHttpRequest. This is a pre-filtering function to sanitize the response. You should return the sanitized data. The function accepts two arguments: The raw data returned from the server and the 'dataType' parameter.
From the jQuery documentation
Here is an example. Notice how the dataFilter in this case is removing the first 2 characters from the response with this code; data.substr(2). For your example you would need to increase that to 5 in order to remove //ABC.
$.ajax({
type: 'POST',
cache: false,
data: {property1:'somevalue',property2:'someothervalue'},
dataFilter: function(data, type) {return data.substr(2)},
dataType: 'json',
url: 'https://www.somedomain.com/api/service/',
success: function(data, stat, resp) {
if(!data.error) {
// good return so do what you need to do
// this is assuming the service returns an 'error' field
// the JSON data is accessible by using data.fieldname format
} else {
// bad return so trap it
}
},
error: function(resp, stat, err) {
// service call failed so trap it
}
});
