根据json对象的值替换json数组里的值

功能：

var fruitArry=[{name:'durian'},{name:'peach'},{name:'banana'},{name:'pitaya'},{name:'apple'},{name:'cherry'}];
      var fruit={'banana':'香蕉','peach':'桃子','durian':'榴莲','pitaya':'火龙果'};

将   fruitArry   中  name 的值根据 fruit 的 key 值进行替换：如果 fruitArry 的值在 fruit 中也有，那就将 fruitArry 替换为 fruit 的值，如果没有，则值不变。

方法一：

    <script type="text/javascript">
        var fruitArry = [{
            name: 'durian'
        }, {
            name: 'peach'
        }, {
            name: 'banana'
        }, {
            name: 'pitaya'
        }];
        var fruit = {
            'banana': '香蕉',
            'peach': '桃子',
            'durian': '榴莲',
            'pitaya': '火龙果'
        };
        for (var key in fruit) {
            for (var i = 0; i < fruitArry.length; i++) {
                if (key == fruitArry[i].name) {
                    fruitArry[i].name = fruit[key];
                }
            }
        }
        console.log(fruitArry);
    </script>

方法二：

     <script type="text/javascript">
         var fruitArry = [{
             name: 'durian'
         }, {
             name: 'peach'
         }, {
             name: 'banana'
         }, {
             name: 'pitaya'
         }, {
             name: 'apple '
         }, {
             name: 'cherry '
         }];
         var fruit = {
             'banana': '香蕉',
             'peach': '桃子',
             'durian': '榴莲',
             'pitaya': '火龙果'
         };
         fruitArry.forEach(function(item) {
             if (fruit[item.name]) {
                 item.name = fruit[item.name];
             }
         });
         console.log(fruitArry);
     </script>

方法三：

    <script type="text/javascript">
        var fruitArry = [{
            name: 'durian'
        }, {
            name: 'peach'
        }, {
            name: 'banana'
        }, {
            name: 'pitaya'
        }, {
            name: 'apple '
        }, {
            name: 'cherry '
        }];
        var fruit = {
            'banana': '香蕉',
            'peach': '桃子',
            'durian': '榴莲',
            'pitaya': '火龙果'
        };
        fruitArry = fruitArry.map(function(item) {
            if (fruit[item.name]) {
                return {
                    name: fruit[item.name]
                }
            } else {
                return {
                    name: item.name
                }
            }
        });
        console.log(fruitArry);
    </script>
