引导程序弹出窗口不起作用 [英] Bootstrap popover is not a function

问题描述

我目前正在尝试开发一个Chrome插件，以发现每个访问的网页中出现的不同名称.

I am currently trying to develop a Chrome plugin that spots occurrences of different names inside each visited web page.

当插件找到名称时，它基本上会在其旁边添加一个图标.单击后，将显示一个引导弹出窗口，其中包含有关此人的更多信息.

When the plugin finds a name, it basically adds an icon next to it. When clicked, a bootstrap popover should appear with more information about the person.

当我尝试运行代码时，出现此错误:

When I try to run my code, I get this error:

VM887:1未捕获的TypeError:$(...).popover不是函数(...)

VM887:1 Uncaught TypeError: $(...).popover is not a function(…)

这是我的代码:

$('head').append('<script async src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.1/jquery.min.js"></script>\
<script async src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>');

$(document).ready(function(){
  var name = "Nicolas";
  // console.log('Document is ready.. scanning for politicians...');
  //var hashmap = db_reader.getHashMap();

  var counter = {i: 0}; //Occurences. Singleton to be passed by reference and not by value.
  $('p').each(function(index) {
    addImage(this, counter);
  });

  $('li').each(function(index) {
    addImage(this, counter)
  });

  $('head').append(
    "<script>$(function(){$('[data-toggle=\"popover\"]').popover();});\
</script>"
  );

});

function addImage(context, counter) {
  var body = $(context).text();
  var word;
  var reg = /[A-Z]+[a-z]*/gm;
  while(word = reg.exec(body)){
    // console.log("while");
    if(word == name){
      // console.log(word);
      var image = '<a href="#" data-toggle="popover" title="Popover Header" data-content="A wonderful content" id="popover'+counter.i+'" class="politicianFind">\
<img alt="name" src="https://s15.postimg.org/pei4ci3fv/fdp.png">\
</a>';
      // console.log("Replacing HTML");
      $(context).html(body.replace(word, word + " " + image));
      counter.i++;
    }
  }
}

我已经进行了很多搜索，但是找不到针对此问题的任何解决方法.

I have already searched a lot but I wasn't able to find any fix for this issue.

推荐答案

我认为这是因为当您调用方法popover时，引导脚本尚未加载.

I think that it's because when you call the method popover the bootstrap script not yet loaded.

您有2个选项:

1. 要在$(window).load上调用方法- http://output.jsbin.com/qoteqe
2. 在DOM中包含引导程序和jQuery引用，而不在脚本中加载它们: http://output.jsbin .com/tamoda

1. To call the method on $(window).load - http://output.jsbin.com/qoteqe
2. Include the bootstrap and jQuery references in the DOM and not load them in the script: http://output.jsbin.com/tamoda

顺便说一句，为什么还要添加另一个jQuery引用?如果您显然使用$('head').append，则页面中已经包含jQuery.不是吗?

By the way why do you add another jQuery reference? If you are using $('head').append clearly you have jQuery in your page already. Isn't?
