How can I show a hidden div when a select option is selected?(10个答案)
25天前关闭
我有一个选择块,其中包含三个类别的元素和与这些类别相关联的div。我希望如果我们选择一个类别,与此类别相关联的div会显示。否则,让它们保持隐藏。我希望以下div:husband_name,number_name只有在我们选择pregnant_wife的时候才显示。但是当我这样做的时候,husband_name div工作正常,而不是number_bytes.这是代码:
<div class="modal-body row">
<form role="form" action="patient/addNew" class="clearfix" method="post" enctype="multipart/form-data">
<div class="form-group col-md-6">
<label for="exampleInputEmail1"><?php echo lang('category'); ?></label>
<select class="form-control m-bot15" name="categorie" value='' id="category" onchange="changeCategorie()">
<option value="F#" > Sélect a category </option>
<option value="pregnant_wife" <?php
if (!empty($patient->category)) {
if ($patient->category== 'pregnantWife') {
echo 'selected';
}
}
?> > pregnant_wife </option>
<option value="Personnal" <?php
if (!empty($patient->category)) {
if ($patient->category== 'Personnal') {
echo 'selected';
}
}
?> > Personnal</option>
<option value="Other" <?php
if (!empty($patient->category)) {
if ($patient->category== 'Other') {
echo 'selected';
}
}
?> > Other</option>
</select>

这是JavaScript代码:
var categorie = document.getElementById("categorie");
divUsband.style.display = 'none';
// divEnfants.style.display = 'none';
function changeCategorie() {
if (categorie.value == "FemmeEnceinte") {
divUsband.style.display = 'block';
// divEnfants.style.display = 'block';
} else {
divUsband.style.display = 'none';
// divEnfants.style.display = 'none';
}
}

首先,你在HTML中有很多错误。当你在一个元素上使用id属性时,它应该是唯一的。其他元素不应该有相同的id。你的select元素没有value属性。它们从用户选择的options元素中获取值。我对你的HTML做了一些修改,我有一个JavaScript脚本,可以隐藏和显示丈夫和孩子的div。

下面是根据用户选择的内容来处理显示和隐藏div的JavaScript。
