Question

(function ($) {
window.AppView = Backbone.View.extend({
  el: $("body"),
  events: {
    "click #add-friend":  "showPrompt",
  },
  showPrompt: function () {
    var friend_name = prompt("Who is your friend?");
  }
});
var appview = new AppView;
})(jQuery);

Can anyone explain me what is el here. Is it element?
Does the el argument accept object, if so can i pass my custom view object where my button or elements need to be added...

Answer 1

Yes it s a DOM element.
No you cannot pass a custom object. You either specify an existing element, or creating one from the tagName, className, id and attributes properties of the view. If you don t specify an element, it defaults to a div

都写在""http://documentcloud.github.com/backbone/#View-el" rel="noreferr" 的官方文件上

Answer 2

Alladnian 回答, 但我要补充的是, 当使用 < code>el 时, 您可以使用 < code>$el , 这是您视图元素中缓存的 jQuery 对象。

所以您总是可以简单地通过您想要使用的标签( 一致性、简洁性和灵活性), 然后将其命名为 < code>$el , 将其用作 jQuery 对象。

this.$el.addClass("active");
