Get function parameters from a JS function which is a string

I am parsing a webpage and I obtain the following JS function as a string

"translate(737.4170532226562,136.14541625976562)"

I want to parse the string to obtain the two parameters of the function.

I can parse the string upto the '(' and ',' and ')' to get the arguments - I wanted to know if there is any other method to get the parameters from this string function.

Solution

  • You can use regex for this purpose. For example this one: /([\d\.]+),([\d\.]+)/

    var str = "translate(737.4170532226562,136.14541625976562)";
var args = /([\d\.]+),([\d\.]+)/.exec(str)
var a1 = args[1], a2 = args[2];

document.write(['First argument: ', a1, '<br> Second argument: ', a2].join(''))
