我有以下几点：
alert("before: " + JSON.stringify(scenario_data)); // Outputs: {"1":{"amount":{"value":"","inputflag":false},"numberout":{"value":"","inputflag":false},"discount":{"value":"","inputflag":false}},"2":{"amount":{"value":"","inputflag":false},"numberout":{"value":"","inputflag":false},"discount":{"value":"","inputflag":false}}}
scenario_data[1]['amount']['value'] = 1234;
alert("After: " + JSON.stringify(scenario_data)); // Outputs: {"1":{"amount":{"value":1234,"inputflag":true},"numberout":{"value":"","inputflag":false},"discount":{"value":"","inputflag":false}},"2":{"amount":{"value":1234,"inputflag":true},"numberout":{"value":"","inputflag":false},"discount":{"value":"","inputflag":false}}}
为什么都scenario_data[1]['amount']['value']和scenario_data[2]['amount']['value']被设置为1234？
因为scenario_data[0]和scenario_data[1]指向同一个对象。因此，当您转换为json时，两个元素都具有相同的表示形式。您可以通过检查的值进行验证scenario_data[0] == scenario_data[1]。
