Question

我有一个Backbone App，我通过API获取Twitter推文，该结果以字符串形式返回结果。我需要的是使字符串中的http可点击。我怎样才能做到这一点？

这是文本字符串：

 Who does John wish he could have sung with over the span of his career? See the video answer here! http://t.co/pbPXaDkGEJ

我希望它像

<span>Who does John wish he could have sung with over the span of his career? See the video answer here! <a href="http://t.co/pbPXaDkGEJ"> click here</a></span>

我尝试过这样的事情：

function replaceURLWithHTMLLinks(text) {
   var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
   return text.replace(exp,"<a href='$1'>$1</a>"); 
}

但那不起作用......

[UPDATE]

好的，我要添加我的Backbone View：

function (App, Backbone) {

    var ArtistTwitter = App.module();

    ArtistTwitter.View = Backbone.View.extend({
        tagName: 'ul',
        className: 'actweets',
        template: 'artistTwitter',
        initialize: function() {
            this.listenTo(this.collection, 'all', this.render);
        },
        serialize: function() {
            return this.collection ? this.collection.toJSON() : [];
        }
    });
    ArtistTwitter.ArtistTwitterCollection = Backbone.Collection.extend({
        url: function() {
            return '/myproject/index.php/api/social_feeds/fetchNewTweet/' + this.artist_id;
        }
    });

    return ArtistTwitter;
}

我尝试在afterRender - 函数中添加上面提到的替换代码但是没有用...

欢迎任何建议......

它正确地替换了链接，但您需要稍微修改它以获得预期的输出。如果我理解正确，您只需将sencond $ 1更改为静态文本'click here'即可获得所需的输出：

function replaceURLWithHTMLLinks(text) {
  var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
  return text.replace(exp,"<a href='$1'>click here</a>"); 
}

这将返回：

replaceURLWithHTMLLinks("Who does John wish he could have sung with over the span of his career? See the video answer here! http://t.co/pbPXaDkGEJ ")

"Who does John wish he could have sung with over the span of his career? See the video answer here! <a href='http://t.co/pbPXaDkGEJ'>click here</a> "

更新：

在这种情况下，我认为你应该能够通过在你的模型视图中添加repleaceURLWithHTMLLinks来获得你想要的东西（你粘贴的视图是你的集合）并实现渲染方法：

ArtistTwitterItemView.View = Backbone.View.extend({
    tagName: 'li',

    replaceURLWithHTMLLinks: function(text) {
       var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
       return text.replace(exp,"<a href='$1'>click here</a>"); 
    },

    // something like this (copy paste will not work but it might get you on the track): 
    // it looks like this should in be a model view 
    // in collections view you should iterate through your collection and call render for each item
    // in the case for model view call replaceURLWithHTMLLinks before rendering:
    render: function(){
       var data = this.model.toJSON();
       _.extend(data, { replacedText: replaceURLWithHTMLLinks(data.text) });
       var html = _.template($(this.template), data);
       this.$el.html(html);
    }
});
