I want to know if its possible to over-ride a setting that is part of an included js that i dont have direct access to.

below is the js in question. the only part i want to change is the Tab-key feature. can I wite a new function to switch back to 'unchecked' onload? I want it unchecked by default.

var useTabKey  = 1;     // 1 = enable tab-key feature / 0 = no tab-key
var tabbedMode = 1;     // Default TabMode in editbox: 1 = On; 0 = Off (This option has no effect if useTabKey is != 1!)
var tspace = "    ";    // Convert tab to value of tspace (default is 4 spaces)
var B_open = 0;
var I_open = 0;
var U_open = 0;
var QUOTE_open = 0;
var PHP_open = 0;
var CODE_open = 0;
var SQL_open = 0;
var HTML_open = 0;

Edited 3 Years Ago by Dani: Formatting fixed

For first 2 lines i.e:

var useTabKey = 1; // 1 = enable tab-key feature / 0 = no tab-key
var tabbedMode = 1;

since these are global variables u can easily change there value.


for third part to change, find out on which event that function is called, then bind ur modified handler to that event.

Thankyou for answering , its called onload I beleive, but how do I....

bind ur modified handler to that event.

I havent got a clue!
