我想總結基於文本框變量提供的過濾器的總分。我在最後附上我的JavaScript。有沒有人有任何建議來總結Angular中的多個字段？Angular JS過濾
我正在將這個簡單的例子集成到一個更大的一組列（如其中的10個）。我正在考慮使用JSON對象來表示每列的總和，但我不確定如何將所有內容與多列數據進行集成。
// app.js
var app = angular.module('sortApp', [])
.controller('mainController', function($scope) {
$scope.sortType = 'fish'; // set the default sort type
$scope.sortReverse = false; // set the default sort order
$scope.searchFish = ''; // set the default search/filter term
$scope.searchName = '';
// create the list of sushi rolls
$scope.sushi = [
{ name: 'Cali Roll', fish: 'Crab', tastiness: 2, score: 3 },
{ name: 'Philly', fish: 'Tuna', tastiness: 4, score: 2 },
{ name: 'Tiger', fish: 'Eel', tastiness: 7, score: 5 },
{ name: 'Rainbow', fish: 'Variety', tastiness: 6: score, 1 }
];
$scope.totalRecords = function(searchFish, searchName) {
\t return $scope.sushi.reduce(function(current, record) {
\t \t if(filterSushi(record, searchFish, searchName))
\t \t {
\t \t \t return current + record.tastiness;
\t \t }
\t \t else
\t \t {
\t \t \t return current;
\t \t }
\t }, 0);
};
});
function filterSushi(record,searchFish, searchName)
{
\t var lowName = null;
\t var lowFish = null;
\t if(searchName.length > 0)
\t {
\t \t lowName = searchName.toLowerCase();
\t }
\t if(searchFish.length > 0)
\t {
\t \t lowFish = searchFish.toLowerCase();
\t }
var termInName = true;
var termInFish = true;
\t \t \t
\t if(lowName != null)
\t {
\t \t termInName = record.name.toLowerCase().indexOf(lowName) > -1;
\t }
\t if(lowFish != null)
\t {
\t \t termInFish = record.fish.toLowerCase().indexOf(lowFish) > -1;
\t }
\t return !(!termInFish || !termInName);
}
app.filter('myTableFilter', function(){
// Just add arguments to your HTML separated by :
// And add them as parameters here, for example:
// return function(dataArray, searchTerm, argumentTwo, argumentThree) {
return function(dataArray, fish, name) {
// If no array is given, exit.
if (!dataArray) {
return;
}
// If no search term exists, return the array unfiltered.
//else if (!searchTerm) {
// return dataArray;
//}
// Otherwise, continue.
else {
var lowName = null;
\t \t var lowFish = null;
\t \t \t if(name.length > 0)
\t \t \t {
\t \t \t \t lowName = name.toLowerCase();
\t \t \t }
\t \t \t if(fish.length > 0)
\t \t \t {
\t \t \t \t lowFish = fish.toLowerCase();
\t \t \t }
// Return the array and filter it by looking for any occurrences of the search term in each items id or name.
return dataArray.filter(function(item){
var termInName = true;
var termInFish = true;
\t \t \t
\t \t \t if(lowName != null)
\t \t \t {
\t \t \t \t termInName = item.name.toLowerCase().indexOf(lowName) > -1;
\t \t \t }
\t \t \t if(lowFish != null)
\t \t \t {
\t \t \t \t termInFish = item.fish.toLowerCase().indexOf(lowFish) > -1;
\t \t \t }
//return termInFish || termInName || termInTastiness;
\t \t \t return !(!termInFish || !termInName);
});
