Set a Field Equal to Something

tmcw () — Fri, 10 Nov 2006 05:55:58 GMT

A basic code sample for tcm_write_macros. It sets a custom field to a value



/* also - custom-1, custom-2, custom-3, custom-4, custom-5, etc for custom fields. */

var obj = document.getElementById('custom-3');

obj.value = "VALUE";

Javascript - Sleep

whitetiger () — Fri, 07 Jul 2006 00:19:01 GMT

// Effettuare uno sleep dello script di uno script



function pause(millisecondi)

{

    var now = new Date();

    var exitTime = now.getTime() + millisecondi;



    while(true)

    {

        now = new Date();

        if(now.getTime() > exitTime) return;

    }

}

Events

willcodeforfoo () — Tue, 13 Jun 2006 01:17:42 GMT

I like being able to attach 'events' to buttons/links like this... don't think prototype can do this



$("a.codeButtonB").click(function(){$("pre.codeB").toggle()});
