[英]show/hide div based on radio button checked
我試圖根據選中的單選按鈕顯示/隱藏文本字段。 這是我的代碼; 如果我不使用表格標簽,效果很好,使用表格標簽時,Javascript不起作用
<script type="text/javascript">
function onchange_handler(obj, id) {
var other_id = (id == 'personal')? 'corporate' : 'personal';
if(obj.checked) {
document.getElementById(id + '_form_fields').style.display = 'block';
document.getElementById(other_id + '_form_fields').style.display = 'none';
} else {
document.getElementById(id + '_form_fields').style.display = 'none';
document.getElementById(other_id + '_form_fields').style.display = 'block';
}
}
</script>
<table>
<tr>
<td colspan="2">
<input type="radio" name="tipo_cadastro" value="individual_form" id="individual_form" style="margin:0px !important" onchange="onchange_handler(this, 'personal');" onmouseup="onchange_handler(this, 'personal');">
<strong>Individual Form</strong>
<input type="radio" name="tipo_cadastro" value="corporation_form" id="corporation_form" style="margin:0px !important" onchange="onchange_handler(this, 'corporate');" onmouseup="onchange_handler(this, 'corporate');">
<strong>Corporation Form</strong>
</td><tr>
<!-- If Individual Form is checked -->
<div id="personal_form_fields">
<tr><td>First Name</td>
<td><input type="text" name="First_Name" value=""></td>
</tr>
<tr><td>Last Name</td>
<td><input type="text" name="Last_Name" value=""></td>
</tr>
</div>
<!-- If Corporation Form is checked -->
<div id="corporate_form_fields" style="display: none;">
<tr><td>Company</td>
<td><input type="text" name="company_name" value=""></td>
</tr>
</div>
</table>
putvande的“奇怪標記”可能意味着您的<div id="personal_form_fields">
在表中,其父級是table
標簽。 那是不對的。 tr
應該包含td
,其中包含div
,而不是相反。
如果您嘗試更改可見性,則可能是此語法錯誤。
只需將一個類添加到每個組的TR中,然后顯示/隱藏該類...
<script type="text/javascript">
function onchange_handler(obj, id) {
var other_id = (id == 'personal')? 'corporate' : 'personal';
if(obj.checked)
{
class_display(id + '_form_fields','block');
class_display(other_id + '_form_fields','none');
} else {
class_display(id + '_form_fields','none');
class_display(other_id + '_form_fields','block');
}
}
function class_display(tr_class,display)
{
var tr_ele = document.getElementsByClassName(tr_class);
for (var i = 0; i < tr_ele.length; ++i) {
var item = tr_ele[i];
item.style.display = display;
}
}
</script>
