I originally blogged about this on my other site lazygnome.net but that was simply a quick place to record it.
I present to you a very quick and handy way of replicating PHP’s trim() function in JS:
return value.replace(/(^s+|s+$)/g, '');
There it is, simple and usable.
I don’t claim to be original with this code. I’m sure that others have done exactly the same themselves. But it surprises me that JS doesn’t come with such a text manipulation method by default.
