我希望将 Backbone.js 与命名空间下划线库一起使用。有谁知道我如何告诉 Backbone 引用 下划线 和不 _

谢谢！马特

截至今天（版本 0.5.3），Backbone 本身还没有准备好，但可以做到：

您需要放置请求 underscore.js 和 backbone.js 的脚本标记 在 script 标记中的第一个/早期，并在 underscore,backbone 脚本之间的脚本中执行 _.noConflict()和其余的脚本加载。这是一个示意图版本：（

<!DOCTYPE html>
<html>
  <head>
    <title>Labbo</title>
    <script src="underscore.js"></script>
    <script src="backbone.js"></script>
    <script>
      var underscore = _.noConflict();
    </script>

    <script>
      // In it's own script tag for readability
      console.log('_ object: ', _);
      console.log('"underscore" object: ', underscore);
      var m = new Backbone.Model({});
      console.log('Dummy backbone model: ', m);
    </script>

    <!-- Load your other scripts. From here on the '_' global isn't defined -->
    <!-- any more. -->
    <!-- <script src="your_other_scripts.js"></script> -->
  </head>

  <body>
    Open Developer Tools / Firebug and check the output in the console.
  </body>
</html>

无法将其放在 jsfiddle 上，因为为了演示，您需要控制脚本标签的确切位置）。

As of today (version 0.5.3) Backbone isn't ready for this in it self but it can be done:

You need to put your script tags requesting underscore.js and backbone.js first/early among your script tags, and do your _.noConflict() in a script between the underscore,backbone scripts and the rest of the script loading. Here's a schematic version:

<!DOCTYPE html>
<html>
  <head>
    <title>Labbo</title>
    <script src="underscore.js"></script>
    <script src="backbone.js"></script>
    <script>
      var underscore = _.noConflict();
    </script>

    <script>
      // In it's own script tag for readability
      console.log('_ object: ', _);
      console.log('"underscore" object: ', underscore);
      var m = new Backbone.Model({});
      console.log('Dummy backbone model: ', m);
    </script>

    <!-- Load your other scripts. From here on the '_' global isn't defined -->
    <!-- any more. -->
    <!-- <script src="your_other_scripts.js"></script> -->
  </head>

  <body>
    Open Developer Tools / Firebug and check the output in the console.
  </body>
</html>

(Couldn't put this on jsfiddle beacuse to demo you need control over excactly where the script tags go).
