jquery calling a function

Question

Hi,

yet again thanks for looking.

i like to call a function (eg. comment_disp, post_disp or any other i create later on).

i have created a json function with url, fname and id can i use fname as a function name?

// on document ready runs
json('comments.php','comment_disp');

• url = url to get
• fname = function
• name id = post or any other data id.

json = function(url,fname,id){
$.getJSON(url,(fname));
}

comment_disp = function(json){
}

Answer 1

Functions are first-class objects in JavaScript. You can put them into parameters directly, no need to transport their name as string.

So instead of

json = function(url,fname,id){ $.getJSON(url,(fname)); }

do

json = function(url,f,id){ $.getJSON(url, f); }

and call it as

json('comments.php', comment_disp);

Answer 2

Assuming your functions are available in the "global scope" (i.e. not written as a private member of another class/constructor), you can call your functions by string name like this:

window['comment_disp']();

This would be the equivalent of calling

comment_disp();
