使用javascript刪除字符串中的特定字符

Question

• 我有一串

    var tStr="[[[{"Name":"A","No":"8000444284"}],{"Name":"B","No":"8485990983"}],{"Name":"C","No":"0000000000"}]"; 

• 在此字符串中，我嘗試刪除所有[和]

我的代碼是：

function trim(str, characters) 
{
  var c_array = characters.split('');
  var result  = '';
  for (var i=0; i < characters.length; i++)
    result += '\\' + c_array[i];
  return str.replace(new RegExp('^[' + result + ']+|['+ result +']+$', 'g'), '');
}

並且此功能用作

trim(str,'[ ]');

在調用var tStr="[[[{"Name":"A","No":"8000444284"}],{"Name":"B","No":"8485990983"}],{"Name":"C","No":"0000000000"}]";

多數民眾贊成在不工作，請任何人幫助我... :)

試試這個。用empty string替換。請參閱演示。

var re = /\[|\]/g;
var str = '[[[{"Name":"A","No":"8000444284"}],{"Name":"B","No":"8485990983"}],{"Name":"C","No":"0000000000"}]';
var subst = '';

var result = str.replace(re, subst);
