run a jquery string command

Question

I have a string that contains a jquery command How can I execute this string?

var myCommand = "$('#update').html('hello world!');";

Why do you have a string that has JavaScript code in it? Where is it coming from? — gen_Eric

You should not try to execute command from string, if you need to reuse them you should use a function:

var myCommand = function(){
    $('#update').html('hello world!');
}

and then call it

myCommand();

Otherwise you must use eval() but it's not a best practice.

Or you could use globalEval() which is better since it doesn't use eval()

var myCommand = function(){
    $('#update').html('hello world!');
}
$(function()
{ myCommand();
});
