I couldn't find a short and sweet answer to this one, so I made an answer and I'm sharing it here if you need it. Enjoy!
// from this
var arr = ['remove', 'specific', 'value', 'from', 'javascript', 'array']; // 6 items
// to this ("specific" value removed)
var arr = ['remove', 'value', 'from', 'javascript', 'array']; // 5 items
// use this (removes "specific")
arr.splice(arr.indexOf('specific'), 1);
// full example
var arr = ['remove', 'specific', 'value', 'from', 'javascript', 'array'];
var value_to_remove = 'specific';
arr.splice(arr.indexOf(value_to_remove), 1);
// note: to support IE (anger rising as I type), you'll need this (thanks James!):
if (!Array.prototype.indexOf)
{
Array.prototype.indexOf = function(elt /*, from*/)
{
var len = this.length >>> 0;
var from = Number(arguments[1]) || 0;
from = (from < 0)
? Math.ceil(from)
: Math.floor(from);
if (from < 0)
from += len;
for (; from < len; from++)
{
if (from in this &&
this[from] === elt)
return from;
}
return -1;
};
}
