Question

我正在设计一个应用程序来执行与数据库相关的一些CRUD操作。作为我的应用程序的一部分，我试图基于两个输入实现搜索，一个是下拉/组合框，另一个是输入。一旦用户输入完成将文本输入文本然后点击搜索，它应该获取与该特定记录相关的所有信息并将其填充到文本框中

无法使用两个输入处理搜索。任何帮助表示赞赏。

这是

var myapp = angular.module("myModule", []);
myapp.controller("myController", function($scope){
	
	var listProducts = [
		{ id: '100', name: "Macy", price: 200, quantity: 2 },
		{ id: '100', name: "Macy", price: 100, quantity: 1 },
		{ id: '101', name: "JCPenny", price: 400, quantity: 1 },
		{ id: '102', name: "Primark", price: 300, quantity: 3 },
		{ id: '103', name: "H&M", price: 600, quantity: 1 }
	];
	
	$scope.listProducts = listProducts;
	
	$scope.del = function(id){
		var txt = confirm("Are you sure??")
			if (txt==true){
				var index = getSelectedIndex(id);
				$scope.listProducts.splice(index,1);
			}
		
	};
	
	$scope.selectEdit = function(id){
		var index = getSelectedIndex(id);
		var product = $scope.listProducts[index];
		$scope.id=product.id;
		$scope.name=product.name;
		$scope.price=product.price;
		$scope.quantity=product.quantity;
	};
	
//	$scope.searchproduct= function(item){
//		var product = 
//	}
	
	function getSelectedIndex(id){
		for(i=0; i<$scope.listProducts.length; i++)
			if($scope.listProducts[i].id == id)
				return i;
		return -1;
	}
});

<!DOCTYPE html>

您需要一个搜索参数对象。您可以在search.id中存储来自组合的输入，并从search.quantity

中的文本输入输入

<select ng-model="search.id">
    <option ng-repeat="products in listProducts">{{products.id}}</option>
</select>
Quantity:
<input type="text" ng-model="search.quantity">

在selectEdit功能中，您将按搜索对象进行过滤。

$scope.selectEdit = function(){
    var index = getSelectedIndex($scope.search);
    ...
}

getSelectedIndex看起来像这样

function getSelectedIndex(search){
    for(i=0; i<$scope.listProducts.length; i++)
        if($scope.listProducts[i].id == search.id && $scope.listProducts[i].quantity == search.quantity)
            return i;
    return -1;
}
