Javascript：数组有点长时不起作用

Question

I want to replace Chinese characters to unicode and the unicode to pinyin (pronunciations of those characters) so that I can make Hansi (Persianized pronunciations). I do this using arrays. I don't have any problem with this:

 // here i got the chinese character and replaced it with unicode      
     var chini =  document.getElementById("ch1").value.charCodeAt(0);       
     var chiniuni= chini.toString(16);   


var mapUni1 = { 
"3007":"ling2", "4e00":"yi1", "4e01":"ding1", "4e02":"kao3", "4e03":"qi1", "4e04":"shang4---shang3", "4e05":"xia4", "4e06":"---", "4e07":"wan4---mo4", "4e08":"zhang4", "4e09":"san1", "4e0a":"shang4---shang3", "4e0b":"xia4", "4e0c":"ji1", "4e0d":"bu4", "4e0e":"yu3---yu4", "4e0f":"mian3", "4e10":"gai4","4e11":"chou3", "4e12":"chou3", "4e13":"zhuan1", "4e14":"qie3---ju1", "4e15":"pi1", "4e16":"shi4", "4e17":"shi4", "4e18":"qiu1", "4e19":"bing3", "4e1a":"ye4", "4e1b":"cong2", "4e1c":"dong1", 
        };

    var roo = new RegExp(Object.keys(mapUni1).join("|"),"gi");
    pinyin = chiniuni.toLowerCase().replace(roo, function(matched){
      return mapUni1[matched];
    });

   document.getElementById("bbb").innerHTML = pinyin

But since there are a lot of Chinese characters (21000 in my work), the array must be a little long, and I read that it can be much much longer. But in my case, when I put a little more in the array, the code does not work at all:

         var chini =  document.getElementById("ch1").value.charCodeAt(0);       
         var chiniuni= chini.toString(16);   


    var mapUni1 = { 
        "3007":"ling2", "4e00":"yi1", "4e01":"ding1", "4e02":"kao3", "4e03":"qi1", "4e04":"shang4---shang3", "4e05":"xia4", "4e06":"---", "4e07":"wan4---mo4", "4e08":"zhang4", "4e09":"san1", "4e0a":"shang4---shang3", "4e0b":"xia4", "4e0c":"ji1", "4e0d":"bu4", "4e0e":"yu3---yu4", "4e0f":"mian3", "4e10":"gai4","4e11":"chou3", "4e12":"chou3", "4e13":"zhuan1", "4e14":"qie3---ju1", "4e15":"pi1", "4e16":"shi4", "4e17":"shi4", "4e18":"qiu1", "4e19":"bing3", "4e1a":"ye4", "4e1b":"cong2", "4e1c":"dong1", "4e1d":"si1", "4e1e":"cheng2", "4e1f":"diu1", "4e20":"qiu1", "4e21":"liang3", "4e22":"diu1", "4e23":"you3", "4e24":"liang3", "4e25":"yan2", "4e26":"bing4", "4e27":"sang1---sang4", "4e28":"shu4", "4e29":"jiu1", "4e2a":"ge4", "4e2b":"ya1", "4e2c":"qiang2---pan2", "4e2d":"zhong1---zhong4", "4e2e":"ji3", "4e2f":"jie4", "4e30":"feng1", "4e31":"guan4", "4e32":"chuan4", "4e33":"chan3", "4e34":"lin2", "4e35":"zhuo1", "4e36":"zhu3", "4e37":"---", "4e38":"wan2",

PS: I know about difficulties of arrays but I have my own reasons to do this only in this way, so please do not suggest to use different methods. Thanks.

Answer 1

The long object has an extra colon at:

 "507b":"lu":"3---lou2", 
            ^
