oPaging是未定义与数据表和Twitter的自举

Question

的一个项目，我用数据表1.10.2用，有一个与引导式的分页，这个脚本：

$.extend($.fn.dataTableExt.oPagination, { 
    bootstrap: { 
     fnInit: function(oSettings, nPaging, fnDraw) { 
     var els, fnClickHandler, oLang; 
     oLang = oSettings.oLanguage.oPaginate; 
     fnClickHandler = function(e) { 
      e.preventDefault(); 
      if (oSettings.oApi._fnPageChange(oSettings, e.data.action)) { 
      return fnDraw(oSettings); 
      } 
     }; 
     $(nPaging).addClass("pagination").append("<ul>" + "<li class=\"prev disabled\"><a href=\"#\">&larr; " + oLang.sPrevious + "</a></li>" + "<li class=\"next disabled\"><a href=\"#\">" + oLang.sNext + " &rarr; </a></li>" + "</ul>"); 
     els = $("a", nPaging); 
     $(els[0]).bind("click.DT", { 
      action: "previous" 
     }, fnClickHandler); 
     return $(els[1]).bind("click.DT", { 
      action: "next" 
     }, fnClickHandler); 
     }, 
     fnUpdate: function(oSettings, fnDraw) { 
     var an, i, iEnd, iHalf, iListLength, iStart, ien, j, oPaging, sClass, _results; 
     oPaging = oSettings.oInstance.fnPagingInfo(); 
     iListLength = 5; 
     an = oSettings.aanFeatures.p; 
     i = void 0; 
     ien = void 0; 
     j = void 0; 
     sClass = void 0; 
     iStart = void 0; 
     iEnd = void 0; 
     iHalf = Math.floor(iListLength/2); 
     if (oPaging.iTotalPages < iListLength) { 
      iStart = 1; 
      iEnd = oPaging.iTotalPages; 
     } else if (oPaging.iPage <= iHalf) { 
      iStart = 1; 
      iEnd = iListLength; 
     } else if (oPaging.iPage >= (oPaging.iTotalPages - iHalf)) { 
      iStart = oPaging.iTotalPages - iListLength + 1; 
      iEnd = oPaging.iTotalPages; 
     } else { 
      iStart = oPaging.iPage - iHalf + 1; 
      iEnd = iStart + iListLength - 1; 
     } 
     i = 0; 
     ien = an.length; 
     _results = []; 
     while (i < ien) { 
      $("li:gt(0)", an[i]).filter(":not(:last)").remove(); 
      j = iStart; 
      while (j <= iEnd) { 
      sClass = (j === oPaging.iPage + 1 ? "class=\"active\"" : ""); 
      $("<li " + sClass + "><a href=\"#\">" + j + "</a></li>").insertBefore($("li:last", an[i])[0]).bind("click", function(e) { 
       e.preventDefault(); 
       oSettings._iDisplayStart = (parseInt($("a", this).text(), 10) - 1) * oPaging.iLength; 
       return fnDraw(oSettings); 
      }); 
      j++; 
      } 
      if (oPaging.iPage === 0) { 
      $("li:first", an[i]).addClass("disabled"); 
      } else { 
      $("li:first", an[i]).removeClass("disabled"); 
      } 
      if (oPaging.iPage === oPaging.iTotalPages - 1 || oPaging.iTotalPages === 0) { 
      $("li:last", an[i]).addClass("disabled"); 
      } else { 
      $("li:last", an[i]).removeClass("disabled"); 
      } 
      _results.push(i++); 
     } 
     return _results; 
     } 
    } 
    }); 

    if ($.fn.DataTable.TableTools) { 
    $.extend(true, $.fn.DataTable.TableTools.classes, { 
     container: "DTTT btn-group", 
     buttons: { 
     normal: "btn", 
     disabled: "disabled" 
     }, 
     collection: { 
     container: "DTTT_dropdown dropdown-menu", 
     buttons: { 
      normal: "", 
      disabled: "disabled" 
     } 
     }, 
     print: { 
     info: "DTTT_print_info modal" 
     }, 
     select: { 
     row: "active" 
     } 
    }); 
    $.extend(true, $.fn.DataTable.TableTools.DEFAULTS.oTags, { 
     collection: { 
     container: "ul", 
     button: "li", 
     liner: "a" 
     } 
    }); 
    } 

}).call(this); 

它工作时，我有一个DataTable，但当我有多个数据表时，它会在线路if (oPaging.iTotalPages < iListLength) {处中断。对于所有数据表，我看到oSettings.oInstance为空，期望最后一个。

我能做些什么才能使它工作？

下面添加

$.fn.dataTableExt.oApi.fnPagingInfo = function (oSettings) 
      { 
       return { 
        "iStart":   oSettings._iDisplayStart, 
        "iEnd":   oSettings.fnDisplayEnd(), 
        "iLength":  oSettings._iDisplayLength, 
        "iTotal":   oSettings.fnRecordsTotal(), 
        "iFilteredTotal": oSettings.fnRecordsDisplay(), 
        "iPage":   oSettings._iDisplayLength === -1 ? 
         0 : Math.ceil(oSettings._iDisplayStart/oSettings._iDisplayLength), 
        "iTotalPages": oSettings._iDisplayLength === -1 ? 
         0 : Math.ceil(oSettings.fnRecordsDisplay()/oSettings._iDisplayLength) 
       }; 
      };
