$( "#selectlist" ).change(function(event) {
  if (this.value == 1 || this.value == 2) {
    $(".form-control").show();
  } else {
    $(".form-control").hide();
  }
});

Answer 2

我会使用名为from django.shortcuts import render, redirect from . models import User from django.contrib import messages # Create your views here. def index(request): return render(request, 'logReg/index.html') def register(request): viewsResponse = User.objects.add_user(request.POST) if viewsResponse['isRegistered']: request.session['user_id'] = viewsResponse['user'].id request.session['user_fname'] = viewsResponse['user'].first_name return redirect('users:success') else: for errors in viewsResponse['errors']: messages.error(request, errors) return redirect('users:index') def success(request): if 'user_id' not in request.session: messages.error(request, 'Must be logged in!') return redirect('users.index') return render(request, 'logReg/success.html') def login(request): viewsResponse = User.objects.login_user(request.POST) if viewsResponse['isLoggedIn']: request.session['user_id'] = viewsResponse['user'].id request.session['user_fname'] = viewsResponse['user'].first_name return redirect('users:success') else: for errors in viewsResponse['errors']: messages.error(request, errors) return redirect('users:index') def logout(request): return redirect('users.index')的自定义属性。更新选择后，您的内容将自动更新。有什么不错的，你要做的就是添加另一个选项和另一个带有valueTie属性的div，然后再启动并运行另一个选项。

＆＃13;

valueTie

＆＃13;

$("#selectlist").change(function () {
  $("[valueTie]").hide()
  $("[valueTie='" + $(this).val() + "']").show();
});

$("#selectlist").change();

＆＃13;

如果选择跨度/隐藏输入值为SMTH
