Question

I have following string which needs to be parsed using JS.

function () {\n     MyClass.prototype.doSomethingFunction();\n       5-6 lines of coding\n  }

I tried parsing it, trimming whitespaces and newlines but nothing worked for me. Please let me know how can I get function name (doSomethingFunction) from the above string.

How I’m getting this string:

I have a queue where my functions are stored. Later in time my code picks a function from this queue (some logic here) and execute them. It works perfectly ok for me. But I just want to print the name of the function out of it! It’s like ‘(classOBJ.myFunctionsQueue[n])()’ is used to execute a function which is stored at nth location in myFunctionsQueue array. Make sense or I’m doing something wrong in here?

Thanks

Try a reg expression matching like this

var str = "function() {\n MyClass.prototype.doSomethingFunction();\n 5 - 6 lines of coding\n}";

var matches = str.match(/prototype\.(.+?)\(\)/);
if(matches){
    alert(matches[1]);
}
