Question

我在验证工作时遇到了一些问题。我基本上需要确保填充所有文本框，并勾选至少一个复选框。文本字段很简单，但填充复选框的方式使其变得困难。这是我的表单看起来的片段，之后还有很多。我可以在复选框上更改事件或删除它们吗？

<form id="orderForm" action="#" method="get" onsubmit="return cdSubmitValidate();">
    <section id="selectCD">
        <h2>Select CDs</h2>
<div class='item'>
        <span class='CDTitle'>A Biography of the Rev. Absalom Dawe</span>
        <span class='CDYear'>2001</span>
        <span class='catDesc'>Comedy</span>
        <span class='CDPrice'>11.70</span>
        <span class='chosen'><input type='checkbox' name='CD[]' value='651' title='11.70' onclick='checkBoxCheck(this)'/></span>
    </div>
<div class='item'>
        <span class='CDTitle'>A Bronx Tale Soundtrack</span>
        <span class='CDYear'>2000</span>
        <span class='catDesc'>Death Metal</span>
        <span class='CDPrice'>7.80</span>
        <span class='chosen'><input type='checkbox' name='CD[]' value='652' title='7.80' onclick='checkBoxCheck(this)'/></span>
    </div>
<div class='item'>
        <span class='CDTitle'>A Little Deeper</span>
        <span class='CDYear'>2000</span>
        <span class='catDesc'>Rap/R&B</span>
        <span class='CDPrice'>8.30</span>
        <span class='chosen'><input type='checkbox' name='CD[]' value='653' title='8.30' onclick='checkBoxCheck(this)'/></span>
    </div>

        <div id="retCustDetails" class="custDetails">
            Forename <input type="text" name="forename" id="forename" />
            Surname <input type="text" name="surname" id="surname" />
        </div>
<p><input type="submit" name="submit" value="Order now!" id="sub1"/></p>

到目前为止试了这个无济于事。

function cdSubmitValidate(){
  var forename = document.getElementById('forename').value;
  var surname = document.getElementById('surname').value;
  var checkboxTicked;

  function checkBoxCheck(elemName){

    if (elemName.checked == true) {
    checkboxTicked = true;
    }else if (elemName.checked == false) {
    checkboxTicked = false;
    }
  };

  if (!forename || !surname || checkboxTicked) {
    alert("Input criteria not met. Please Review and try again");
    return false;
  }

};

我认为这会解决问题，首先将checkBoxCheck()函数移出cdSubmitValidate()函数，也移动checkboxTicked。我认为问题是在控制台记录的函数内调用一个函数：

未捕获的ReferenceError：未定义checkBoxCheck。

同样在你的if声明中，条件是

if (!forename || !surname || checkboxTicked)

我将其更改为if (!forename || !surname || !checkboxTicked)

CodePen

var checkboxTicked;

function cdSubmitValidate() {
  var forename = document.getElementById('forename').value,
    surname = document.getElementById('surname').value;

  if (!forename || !surname || !checkboxTicked) {
    alert("Input criteria not met. Please Review and try again");
    return false;
  }

};

function checkBoxCheck(elemName) {

  if (elemName.checked == true) {
    checkboxTicked = true;
  } else if (elemName.checked == false) {
    checkboxTicked = false;
  }
};
