28.json数组，select选择，input输出对应数据

效果：选择对应的车类，下面的input会实时出现车价。

html:

<form action="" class="priceModelform1"> <!-- select选择  motorcycle1 --> <select class="motorcycle1" name="motorcycle1" id="motorcycle1" οnchange="motorcycleChange1()" > <option value="">请选择</option> <option value="0">汽车</option> <option value="3">轿车</option> </select> <!-- input输出数据  purchase1 --> <input class="purchase1" type="number" readonly="readonly" value="">

</form>

js:

var cartConfig={ "0":{"purchaseMoney":10}, "3":{"purchaseMoney":7.5}}; function motorcycleChange1(){ var motorcycle1= $("#motorcycle1 option:selected").val();//console.log(motorcycle1); var a= $(".purchase1").val(cartConfig[motorcycle1].purchaseMoney);//console.log(a); }
