未捕获的语法错误:意外标记: [英] Uncaught SyntaxError: Unexpected token :

问题描述

我在我的 MooTools 脚本中运行 AJAX 调用，这在 Firefox 中运行良好，但在 Chrome 中我收到一个 Uncaught SyntaxError: Unexpected token : 错误，我无法确定原因.注释掉代码以确定错误代码的位置不会产生任何结果，我认为这可能是返回 JSON 的问题.在控制台中检查我看到返回的 JSON 是这样的:

I am running an AJAX call in my MooTools script, this works fine in Firefox but in Chrome I am getting a Uncaught SyntaxError: Unexpected token : error, I cannot determine why. Commenting out code to determine where the bad code is yields nothing, I am thinking it may be a problem with the JSON being returned. Checking in the console I see the JSON returned is this:

{"votes":47,"totalvotes":90}

我没有发现它有任何问题，为什么会出现这个错误?

I don't see any problems with it, why would this error occur?

vote.each(function(e){
  e.set('send', {
    onRequest : function(){
      spinner.show();
    },
    onComplete : function(){
      spinner.hide();
    },
    onSuccess : function(resp){
      var j = JSON.decode(resp);
      if (!j) return false;
      var restaurant = e.getParent('.restaurant');
      restaurant.getElements('.votes')[0].set('html', j.votes + " vote(s)");
      $$('#restaurants .restaurant').pop().set('html', "Total Votes: " + j.totalvotes);
      buildRestaurantGraphs();
    }
  });

  e.addEvent('submit', function(e){
    e.stop();
    this.send();
  });
});

推荐答案

我刚刚解决了这个问题.标准请求调用出现问题，所以这是我使用的代码:

I have just solved the problem. There was something causing problems with a standard Request call, so this is the code I used instead:

vote.each(function(element){                
  element.addEvent('submit', function(e){
    e.stop();
    new Request.JSON({
      url : e.target.action, 
      onRequest : function(){
        spinner.show();
      },
      onComplete : function(){
        spinner.hide();
      },
      onSuccess : function(resp){
        var j = resp;
        if (!j) return false;
        var restaurant = element.getParent('.restaurant');
        restaurant.getElements('.votes')[0].set('html', j.votes + " vote(s)");
        $$('#restaurants .restaurant').pop().set('html', "Total Votes: " + j.totalvotes);
        buildRestaurantGraphs();
      }
    }).send(this);
  });
});

如果有人知道标准 Request 对象为什么会给我带来问题，我很想知道.

If anyone knows why the standard Request object was giving me problems I would love to know.
