使用Chrome扩展程序隐藏关键字的父级

我是Chrome扩展程序的新手，所以我很难知道为什么我没有得到预期的结果。

我有一个脚本，可让您添加关键字。我希望我的程序跟踪关键字并隐藏关键字的父div。本质上，它将过滤掉您不想看到的内容。就像贾斯汀·比伯或金·卡戴珊。

我可以毫无问题地添加关键字，但无法隐藏内容。

我认为问题是我可能没有正确定位正在查看的页面的dom。

可能缺少许可？

有人可以告诉我如何使用扩展程序吗？

keyword.js

$(document).ready(function () {

$('#add').click( function() {
   var Description = $('#description').val();
  if($("#description").val() === '') {
    $('#alert').html("<strong>Warning!</strong> You left the to-do empty");
    $('#alert').fadeIn().delay(1000).fadeOut();
    return false;
   }
   $('#keyWords').prepend("<li><input id='check' name='check' type='checkbox'/>" + Description + "</li>");
   $('#form')[0].reset();
   var keyWords = $('#keyWords').html();
   localStorage.setItem('keyWords', keyWords);
   return false;
});

if(localStorage.getItem('keyWords')) {
$('#keyWords').html(localStorage.getItem('keyWords'));
}

$('#clear').click( function() {
window.localStorage.clear();
location.reload();
return false;
});

}); // End of document ready function


$(document).ready(function() {
  $("div p:contains(localStorage.getItem('keyWords')).parent('div').hide()");
}); //end of document ready function

这是我的Manifest.json

  "version" : "1.0",
   "permissions": [
   "activeTab",
   "storage"
   ],

      "128": "icon128.png"        
  }
  },
     "manifest_version": 2
}

您需要将项目存储在数组中，因为:contains()只能处理单个字符串。

更新的代码：

var keyWordArray = [];
//if the existing local storage was not an array, delete it
if(localStorage["keyWords"].substr(0,1) != '[') {
    //empty local storage
    localStorage["keyWords"] = '';
} else {
    //parse the array, and store it in keyWordArray
    keyWordArray = JSON.parse(localStorage["keyWords"]);
}



$(document).ready(function () {

    $('#add').click( function() {
    var Description = $('#description').val();
    if($("#description").val() === '') {
        $('#alert').html("<strong>Warning!</strong> You left the to-do empty");
        $('#alert').fadeIn().delay(1000).fadeOut();
        return false;
        }

    $('#form')[0].reset();
    var keyWords = $('#keyWords').html();

    //add the new keyword to the array
    keyWordArray.push(Description);
    //overwrite the array in localStorage with the new, updated array
    localStorage["keyWords"] = JSON.stringify(keyWordArray);
    //call loadKeyWords() to rebuild the UL and hide any matching elements
    loadKeyWords();
    return false;
    });


    function loadKeyWords() {
    //clear the existing data
        $('#keyWords').html('');
    //for all the items in the array...
        for(var i = 0; i < keyWordArray.length; i++) {
        //add them to the UL
            $('#keyWords').append('<li><input id="check" name="check" type="checkbox">'+keyWordArray[i]+'</li>');
      //and hide any DOM elements that have the keyword
      $("div:contains('"+keyWordArray[i]+"')").hide();    
        }
    }

    $('#clear').click( function() {
        window.localStorage.clear();
        location.reload();
        return false;
    });

    loadKeyWords();
}); //end of document ready function
