Question

我正在尝试更改我的函数，我可以搜索数组以尝试匹配数组项的任何部分并返回其索引值，此时它必须与整个searchTerm匹配。

        function arrayObjectIndexOf(myArray, searchTerm, property) {
            for (var i = 0, len = myArray.length; i < len; i++) {
                if (myArray[i][property] === searchTerm) return i;
            }
            return -1;
        }
        $scope.input.icon = "https://mapbuildr.com/assets/img/markers/solid-pin-blue.png";
        var look = arrayObjectIndexOf($scope.icons, $scope.input.icon, 'imageSrc');

以下是我的示例图标数组。

        $scope.icons = [
            {text: 'Black Solid', imageSrc: 'https://mapbuildr.com/assets/img/markers/solid-pin-black.png' },
            {text: 'Blue Solid', imageSrc: 'https://mapbuildr.com/assets/img/markers/solid-pin-blue.png' },
            {text: 'Green Solid', imageSrc: 'https://mapbuildr.com/assets/img/markers/solid-pin-green.png' },
            {text: 'Purple Solid', imageSrc: 'https://mapbuildr.com/assets/img/markers/solid-pin-purple.png' },
            {text: 'Red Solid', imageSrc: 'https://mapbuildr.com/assets/img/markers/solid-pin-red.png' },
            {text: 'Yellow Solid', imageSrc: 'https://mapbuildr.com/assets/img/markers/solid-pin-yellow.png' },
            {text: 'Orange Solid', imageSrc: 'https://mapbuildr.com/assets/img/markers/solid-pin-orange.png' }
        ];

这就是我要在$scope.icons数组中匹配的内容，它将返回索引值

        $scope.pin = "/assets/img/markers/solid-pin-red.png";

您只需使用JavaScript .search()方法。

这将搜索您的字符串，如果找不到相等的子字符串将返回-1。所以你的比较应该是这样的：

if (myArray[i][property].search(searchTerm) !== -1) 
    return i;

这是JSFiddle来说明：http://jsfiddle.net/vxcjw45d/7/

Javascript匹配数组和返回索引值
