Question

我正在创建一个表单部分，当用户选中相应的复选框时，该部分显示输入字段（文本或选择字段）。我遇到的问题是，如果您显示了选择和一个文本输入，如果您尝试单击要键入的文本字段，它将跳转焦点到选择，使得无法在字段中键入。

我使用jQuery来实现功能（最新版本）并执行以下javascript代码来实现此目的。随之而来的HTML就在这之下。

//Class Year Dropdown
$("#ifClassScholashipsSelected").css("display", "none");
$(".enableClassYearSelection").click(function() {
    if ($("input[name=Class_Scholarships]:checked").val() == "class_scholarships") {
        $("#ifClassScholashipsSelected").slideToggle("fast"); //Slide Down Effect
    } else {
        $("#ifClassScholashipsSelected").slideToggle("fast"); //Slide Up Effect
    }
});
//Other Funds Dropdown
$("#ifOtherFundsSelected").css("display", "none");
$(".enableOtherFunds").click(function() {
    if ($('input[name=OtherFunds]:checked').val() == "other_funds") {
        $("#ifOtherFundsSelected").slideDown("fast"); //Slide Down Effect
    } else {
        $("#ifOtherFundsSelected").slideUp("fast"); //Slide Up Effect
    }
});
//In Memory Of Dropdown
$("#ifInMemoryOfSelected").css("display", "none");
$(".enableInMemoryOf").click(function() {
    if ($('input[name=InMemoryOf]:checked').val() == "in_memory_of") {
        $("#ifInMemoryOfSelected").slideDown("fast"); //Slide Down Effect
    } else {
        $("#ifInMemoryOfSelected").slideUp("fast"); //Slide Up Effect
    }
});
//In Honor Of Dropdown
$("#ifInHonorOfSelected").css("display", "none");
$(".enableInHonorOf").click(function() {
    if ($('input[name=InHonorOf]:checked').val() == "in_honor_of") {
        $("#ifInHonorOfSelected").slideDown("fast"); //Slide Down Effect
    } else {
        $("#ifInHonorOfSelected").slideUp("fast"); //Slide Up Effect
    }
});

这对以下代码产生影响：

<input type="checkbox" name="Class_Scholarships" value="class_scholarships" class="enableClassYearSelection" />
    <label><strong>Class Scholarships</strong>

<div id="ifClassScholashipsSelected">

Answer 1

这是因为您的HTML无效。

在HTML的开头附近，您打开<label>标记。在<label>标记内，您可以打开<div>标记。然后，在关闭<label>代码之前关闭<div>代码。

这是禁忌。移动您的</label>标记即可运行：

更改： jsFiddle

<label><strong>Class Scholarships</strong>  <div id="ifClassScholashipsSelected"> <em>Please select the appropriate class below</em></label> <br />

要 jsFiddle

<label><strong>Class Scholarships</strong></label>  <div id="ifClassScholashipsSelected"> <em>Please select the appropriate class below</em><br />

Answer 2

因为这行问题

<label><strong>Class Scholarships</strong>
<!--Dropdown if selected-->
<div id="ifClassScholashipsSelected">
<em>Please select the appropriate class below</em></label> <br />
    <select name="SelectedClassYear">

您在Div之前打开标签并在Div中关闭它。

 <label> 
 <div>
 </label> 
 </div>

这是The JsFiddle Demo
