我对bootstrap的popover和骨干有一个奇怪的问题。
我的骨干代码:
App.Views.UploadBox = Backbone.View.extend({
el: '#upload-box',
events: {
'click #upload-file': 'openPicker',
'change #upload-file-input': 'handleFileUpload'
//'mouseover #upload-file': 'hoverMessage'
},
initialize: function () {
this.uploader = this.$('#upload-file-input');
this.$("#upload-file").popover({ title: 'some title', content: 'helo world' });
this.button = this.$('#upload-file');
}, ...
上传框:
<div class="span2 offset1" id="cannon-upload-box">
<a href="#" class="btn media-header span10"
id="upload-file" rel="popover">UploadFile</a>
<input id="upload-file-input"
type="file" placeholder="Choose File" style="display: none">
</div>
代码应该做什么:当将鼠标悬停在a元素(id = upload-file)上时,应该是一个弹出消息。
代码实际在做什么:当悬停没有任何反应时,但是当单击按钮时,骨干操作会根据需要被触发,但也会弹出跳转但作为常量元素!

设置弹出框时需要触发选项,如下所示:
this.$("#upload-file").popover({
title: 'some title',
content: 'helo world' ,
trigger: 'hover' // show up on hover default is 'click'
});
试试吧!
