如果网址中存在“ id”参数，则需要重定向网址；如果网址中不存在“ id”参数，则无法正常工作

Question

我有一些代码，首先，如果URL中有“ id”参数，则语句URL成功重定向。 如果删除了“ id”参数，则会显示空白页。 如果声明可行，还会在下面列出吗？

/ *实际值* /

if(incomingPayload && incomingPayload.id && incomingPayload.id != 12345){
        incomingPayload.id = 12345;
}

已修复

      if(incomingPayload && incomingPayload.id && incomingPayload.id != 12345){
            incomingPayload.id = 12345;
            console.log('first if statement');
        }
        else if (incomingPayload || incomingPayload.id || incomingPayload.id == "") {
            incomingPayload.id = 12345;
            console.log('second if staement', incomingPayload.id )
        }

如果URL中未提及“ id”参数，我想重定向

Answer 1

这是我的答案吗？

 if(incomingPayload && incomingPayload.id && incomingPayload.id != 1234){
            incomingPayload.id = 1234;
            console.log('came here because different id params available');
        }
        else if (!incomingPayload.id) {
            incomingPayload.id = 1234;
            console.log('came here because no id params')
        }
