我可以在ajax错误调用中使用变量而不是函数名称吗？

Question

I have an Ajax call that works fine, but I am now trying to polish the code a bit

                $.ajax({
                url: wbURL,
                dataType: "xml",
                contentType: "text/xml; charset=\"utf-8\"",
                type: "POST",
                headers: '@"HEADER DATA',
                data: dataPacket,

                success: dealWithResonse,

                error: dealWithError
            });

what I am now trying to do is replace the success and error function names with variables so I can use it for other jobs.

var SuccessFunctionCall =  dealWithResonse;                      
var ErrorFunctionCall = dealWithError;

                $.ajax({
                url: wbURL,
                dataType: "xml",
                contentType: "text/xml; charset=\"utf-8\"",
                type: "POST",
                headers: '@"HEADER DATA',
                data: dataPacket,

                success: SuccessFunctionCall,

                error: ErrorFunctionCall
            });

But my program stops at this point, assumingly as it can't find a function called ErrorFunctionCall.

can I use a variables vaule instead of an actual function name?

Thank you in advance

Answer 1

You may define those functions as global and assign them to what you want:

var SuccessFunctionCall = function(){dealWithResonse()};
var ErrorFunctionCall = function(){dealWithError()};

and call them as members of window:

success: window[SuccessFunctionCall](),
error: window[ErrorFunctionCall]()

Finally I have to say that I am not sure why you want to assign functions to variable names. You may define those functions directly and call them as you need.

Answer 2

You should define those functions in your variables as shown below:

 $(document).ready(function(){ var SuccessFunctionCall = function dealWithResonse(){ console.log("success"); }; var ErrorFunctionCall = function dealWithError(){ console.log("error"); }; $.ajax({ url: 'http:test', dataType: "xml", contentType: "text/xml; charset=\\"utf-8\\"", type: "POST", headers: '@"HEADER DATA', data: '', success: SuccessFunctionCall, error: ErrorFunctionCall }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js"></script>
