It is great to write plugins that make your development (and hopefully
others too) faster and easier. I would just like to point out a few
things that could make your plugin a little more robust.
First a plugin's 'this' points to the jQuery object. With that in mind
you can simply write the above plugin like this:
jQuery.fn.fieldFocus = function() {
this.get(0).focus();
};
And if you wanted to be able to chain method together you would do it like this:
jQuery.fn.fieldFocus = function() {
this.get(0).focus();
return this;
};
Or you could call focus on each of the elements in the jQuery object like this:
jQuery.fn.fieldFocus = function() {
return this.each(function() {
if (this.focus) this.focus();
});
};
Inside of the each method the 'this' points to the actual DOM element
and not the jQuery object. I check for focus first so as not to cause
an error on elements that don't have the method.
Hope that helps.
