Question

请教一下jquery选择器 这样写是什么意思？

$({deg: 0}).animate({deg: angle}, {
duration: duration,
easing: easing,
step: function(now) {
$elem.css({
transform: 'rotate(' + now + 'deg)'
});
},
complete: complete || $.noop
});
其中$({deg:0}) 这样写是什么意思。

Answer 1

// 排除class为buyao的子元素
$('div>:not(.buyao)')

Answer 2

你好

{deg:0} 是代表一个 object

追问

那如果这么写$({deg:0})是什么意思

追答

范例: ( demo: http://jsfiddle.net/TrueBlueAussie/cfmzau1w/ )

I'm a div!

// Create a pseudo jQuery object (not connected to a DOM element)
var po = $({
deg: 0
});

// This is just the target object we want to change
$elem = $('#result');

// Use animate on the object, to make use of the step callback
po.animate({
deg: 360
}, {
duration: 5000,
step: function (now) {
// Take the computed value and use it on a real element!
$elem.css({
transform: 'rotate(' + now + 'deg)'
});
}
});
