确保选中页面上的所有单选按钮。

Question

我有一个页面，下面有很多单选按钮。我的用户必须 检查每一行。我正在寻找一种点击我的保存按钮的方式 我检查了所有单选按钮，并确保使用有限的 javascript 或 jquery 代码检查它们。

我怎样才能做到这一点？

            <div id="HealthCheck1">           
                <div id="HCBudget">
                    <label for="budgethealth">Budget Health</label>
                    <span class="radiored"><input type="radio" id="bhred" name="budgethealth" value="red" @(Model.BudgetHealth == "3" ? "checked='checked'" : "")></input></span>
                    <span class="radioyellow"><input type="radio" id="bhyellow" name="budgethealth" value="yellow" @(Model.BudgetHealth == "2" ? "checked='checked'" : "")></input></span>
                    <span class="radiogreen"><input type="radio" id="bhgreen" name="budgethealth" value="green" @(Model.BudgetHealth == "1" ? "checked='checked'" : "")></input></span>
                </div>
                <hr>
                <div id="HCTeam">
                    <label for="teamhealth">Team Health</label>
                    <span class="radiored"><input type="radio" id="thred" name="teamhealth" value="red" @(Model.TeamHealth == "3" ? "checked='checked'" : "")></input></span>
                    <span class="radioyellow"><input type="radio" id="thyellow" name="teamhealth" value="yellow" @(Model.TeamHealth == "2" ? "checked='checked'" : "")></input></span>
                    <span class="radiogreen"><input type="radio" id="thgreen" name="teamhealth" value="green" @(Model.TeamHealth == "1" ? "checked='checked'" : "")></input></span>
                </div>
                <hr>
                <div id="HCRisk">
                    <label for="riskhealth">Risk Health</label>
                    <span class="radiored"><input type="radio" id="rhred" name="riskhealth" value="red" @(Model.RiskHealth == "3" ? "checked='checked'" : "")></input></span>
                    <span class="radioyellow"><input type="radio" id="rhyellow" name="riskhealth" value="yellow" @(Model.RiskHealth == "2" ? "checked='checked'" : "")></input></span>
                    <span class="radiogreen"><input type="radio" id="rhgreen" name="riskhealth" value="green" @(Model.RiskHealth == "1" ? "checked='checked'" : "")></input></span>
                </div>
            </div>      
            <div id="ProgHealthStat" class="btnholder">
                <button id="Save" class="sendbtn">Save Changes</button>
            </div>

我尝试了这行代码，但没有运气。尽管单选按钮都被选中，但我仍然收到警报。

            $('div.HealthCheck1:not(:has(:radio:checked))')

Answer 1

为每个包含单选按钮的 div 赋予一个类属性（例如 class="foo"）。然后你可以这样做：

$(document).ready(function() {
  $('#Save').on('click', function() {
    if ($('.foo:not(:has(:radio:checked))').length) {
      alert('Please finish filling out the form');
    }
  });
})
