If I call
$(".myClass")
I get an array of elements. If I now want to get the first element as jquery element I would do something like this:
$($(".myClass").get(0))
So I wrap the DOM-Element, which I get from the array again with the jQuery operator. Is there a more elegant way to do this? Some get method, which returns a jQuery element for example?
The jQuery selector finds particular DOM element(s) and wraps them with jQuery object. For example, document. getElementById() in the JavaScript will return DOM object whereas $('#id') will return jQuery object.
$() = window. jQuery() $()/jQuery() is a selector function that selects DOM elements. Most of the time you will need to start with $() function. It is advisable to use jQuery after DOM is loaded fully.
The jQuery inArray() method is used to find a specific value in the given array. If the value found, the method returns the index value, i.e., the position of the item. Otherwise, if the value is not present or not found, the inArray() method returns -1. This method does not affect the original array.
ready(function() { $('#list li'). click(function() { alert($(this). attr("id")); alert($(this). text()); }); });
Use the eq()
method:
$(".myClass").eq(0)
This returns a jQuery object, whereas .get()
returns a DOM element.
.eq()
lets you specify the index, but if you just want the first you can use .first()
, or if you just want the last you can use (surprise!) .last()
.
"I get an array of elements."
No you don't, you get a jQuery object which is an array-like object, not an actual array.
If you plan to use jQuery much I suggest spending half an hour browsing through the list of all methods.
