与其他 Javascript 框架相比，为什么 jQuery 被如此广泛地采用?

I have used both jQuery and MooTools. This particular essay tends to reflect how I feel about both frameworks. jQuery is great for DOM Manipulation, but seem to be limited to helping you do that.

功能方面，jQuery 和 MooTools 可以轻松实现 DOM 选择和操作:

// jQuery
$('#someContainer div[class~=dialog]')
    .css('border', '2px solid red')
    .addClass('critical');

// MooTools
$('#someContainer div[class~=dialog]')
    .setStyle('border', '2px solid red')
    .addClass('critical');

jQuery 和 MooTools 允许轻松实现 AJAX:

// jQuery
$('#someContainer div[class~=dialog]')
     .load('/DialogContent.html');

// MooTools (Using shorthand notation, you can also use Request.HTML)
$('#someContainer div[class~=dialog]')
     .load('/DialogContent.html');

jQuery 和 MooTools 可以轻松实现 DOM 动画:

// jQuery
$('#someContainer div[class~=dialog]')
    .animate({opacity: 1}, 500);

// MooTools (Using shorthand notation, you can also use Fx.Tween).
$('#someContainer div[class~=dialog]')
    .set('tween', {duration: 500}) 
    .tween('opacity', 1);

jQuery 提供以下附加功能:
