ngTable自定义/重写过滤器

在使用ngTable 时用到了需要进行按时间过滤，但是ngTable并没有该功能，所以需要自定义过滤器，但是如果自定义了过滤器，则会覆盖原来的，所以就需要重写过滤器

ngTable过滤器的原理是按照过滤的条件遍历所有的列表项内容，如果满足过滤条件则返回true，显示该记录，如果不满足条件则返回false，不显示该条记录，过滤条件有任何变化都会触发过滤

text:根据字符匹配，如果被过滤的值有该字符，则显示该记录

number:根据数值进行匹配，如果数值相等，则显示该记录

select:根据下拉列表选择的值进行匹配，如果值相等，则显示该记录

添加自定义的过滤器控件
- 在HTML中

<script type="text/ng-template" id="/filter/js/startDateFilter.html"> <input type="text"> </script>

添加自定义的过滤器控件
- 在js中

$scope.customFilter = {
            start:{
                id:'/filter/js/startDateFilter.html',placeholder:'Start'
            }
        }

需要在ngTable的配置中指定过滤器

$scope.userTable = new NgTableParams({},{
                // initial sort order
                filterDelay: 0,filterOptions: {filterFn: $scope.customFilterFn},dataset: data
            });

为指定列设置控件

<td data-title="'日期'" filter="customFilter"> {{user.date|date:'yyyy-MM-dd'}} </td>

重写过滤器方法，实现过滤器功能

$scope.customFilterFn = function (date,filterValues) {
 return data.filter(function (item) {
                var result = true;
                if (typeof(filterValues.name) != undefined && filterValues.name != null) {
                    result = result && (item.name.indenOf(filterValues.name) > -1);
                }

                if (typeof(filterValues.sex) != undefined && filterValues.sex != null) {
                    result = result && (item.sex == filterValues.sex);
                }

                if (typeof(filterValues.startDate) != undefined && filterValues.startDate != null) {
                    result = result && (item.startDate >= filterValues.startDate);
                }
 return result;
            })
        }

ngTable自定义/重写过滤器

ngTable过滤器的原理是按照过滤的条件遍历所有的列表项内容，如果满足过滤条件则返回true，显示该记录，如果不满足条件则返回false，不显示该条记录，过滤条件有任何变化都会触发过滤
