javascript - 显示/隐藏单选表格

我试图显示“个人”形式并在选中“个人”单选时隐藏“父”形式，并试图显示“父母”形式并在选中父单选时隐藏“个人”形式。我的JavaScript函数似乎不起作用，有什么问题的想法吗？

HTML：

<!-- Radio check 1 -->
    <div class="form-check form-check-inline">

CSS：

#individual {
    display: block;
}

#parent {
    display: none;
}

JavaScript：

function radioCheck() {
    var radio1 = document.getElementById("radio1");
    var radio2 = document.getElementById("radio2");
    var individual = document.getElementById("individual");
    var parent = document.getElementById("parent");
    if (radio2.checked == true){
        individual.style.display = "none";
        parent.style.display = "block";
    }
    else {
        individual.style.display = "block";
        parent.style.display = "none";
    }
}

最佳答案

由于默认情况下选中了一个单选按钮，因此您必须在页面加载时调用或调用radioCheck()。同样不要忘记关闭所有input元素。

function radioCheck() {
    var radio1 = document.getElementById("radio1");
    var radio2 = document.getElementById("radio2");
    var individual = document.getElementById("individual");
    var parent = document.getElementById("parent");
    if (radio2.checked == true){
        individual.style.display = "none";
        parent.style.display = "block";
    }
    else {
        individual.style.display = "block";
        parent.style.display = "none";
    }
}
radioCheck()

<!-- Radio check 1 -->
<div class="form-check form-check-inline">
    <label class="form-check-label">
        <input class="form-check-input" type="radio" name="radios" id="radio1" onclick="radioCheck()" checked/>
        Individual
    </label>
</div>

<!-- Radio check 2 -->

<div class="form-check form-check-inline">
    <label class="form-check-label">
        <input class="form-check-input" type="radio" name="radios" id="radio2" onclick="radioCheck()"/>
        Parent of a child
    </label>
</div>

<!-- Form for individual -->
