我有一个事件的视图。
events: {
'click button.add-prediction': 'addPrediction'
},
addPrediction: function(event) {
var currentPredictions = this.model.get('count');
this.model.set('count', currentPredictions + 1);
this.$el.find('.add-prediction').html('predicted').addClass('selected');
},
这样做:
this.$el.find('.add-prediction').html('predicted').addClass('selected');
似乎不是正确的方法,但是当我这样做时,
$(event.target).html('predicted').addClass('selected');
DOM没有更新,为什么?我做错了什么?
这是完整视图。
Event.Views.PredictionsView = Backbone.View.extend({
tagName: 'div',
className: 'stats',
events: {
'click button.add-prediction': 'addPrediction',
'click button.add-prediction.selected': 'removePrediction'
},
initialize: function() {
this.model.on('change', this.render, this);
},
removePrediction: function() {
var currentPredictions = this.model.get('count');
this.model.set('count', currentPredictions - 2);
this.$el.find('.add-prediction').html('Predict').removeClass('selected');
this.$el.removeClass('selected');
this.$el.parent().find('.add-prediction').removeAttr('disabled');
},
addPrediction: function() {
var currentPredictions = this.model.get('count');
this.model.set('count', currentPredictions + 1);
this.$el.find('.add-prediction').html('Remove prediction').addClass('selected');
this.$el.addClass('selected');
this.$el.parent().find('.add-prediction:not(.selected)').attr('disabled', 'true');
},
setTemplate: function() {
var that = this;
$.get('templates/singleEvent/team-details.html', function(data) {
that.template = _.template(data);
that.render();
}, 'html');
return this;
},
render: function() {
var eventTemplate = this.template(this.model.toJSON());
$(this.el).html(eventTemplate);
return this;
}
});
不幸的是我不能制作一个jsFid,因为它过于复杂并且使其工作需要很长时间。 谢谢。
答案 0 :(得分:1)
event.target不要参考按钮。
event.target [0]指按钮。
尝试
$(event.target[0]).html('predicted').addClass('selected');
或
event.target.html('predicted').addClass('selected');
