我有一个HTML表,其中包含一个带有3个选项的下拉列表,是,否,豁免,还有一个复选框。我设置了Yes = 1,No = 0和Exempt = 2的值。在页面加载时,如果下拉值等于0或2,则应禁用该复选框。如果下拉值等于1,则应启用该复选框。但是,目前我没有得到正确的结果。我之前能够得到第一行的值,但是没有遍历整个表格。
如何遍历整个表格以查找下拉列表的每个值,还可以根据下拉列表中的内容启用/禁用复选框?
使用Javascript:
$(document).ready(function () {
$('#billing_table tr').each(function() {
var checked = $(this).find($(".billed-select")).val();
console.log(checked);
if(checked != "1") {
$('.paid').attr('disabled', true);
} else {
$('.paid').attr('disabled', false);
}
});
});
HTML表:
<table id="billing_table">
<thead>
<tr>
<td style="display: none">Account</td>
<td>Collector Name</td>
<td>Customer</td>
<td>Bill Date</td>
<td>Days Until<br>Next Action</td>
<td>Next Action</td>
<td>Billed</td>
<td>Bill<br>Amount</td>
<td>Payment<br>Due Date</td>
<td>Notes</td>
<td>Paid</td>
<td>Save</td>
</tr>
</thead>
<tbody>
<?php
foreach ($dbh->query($bill) as $rows) {
?>
<tr class="row">
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<?php if ($rows ['Billed Status'] == 'Billed') {?>
<td>
<select class="billed-select">
<option class="selection" value="1" selected>Yes</option>
<option class="selection" value="0">No</option>
<option class="selection" value="2">Exempt</option>
</select>
</td>
<?php } else if ($rows ['Billed Status'] == 'Unbilled'){ ?>
<td>
<select class="billed-select">
<option class="selection" value="1">Yes</option>
<option class="selection" value="0" selected>No</option>
<option class="selection" value="2">Exempt</option>
</select>
</td>
<?php } else if ($rows ['Billed Status'] == 'Exempt'){ ?>
<td>
<select class="billed-select">
<option class="selection" value="1">Yes</option>
<option class="selection" value="0">No</option>
<option class="selection" value="2" selected>Exempt</option>
</select>
</td>
<?php } ?>
<td></td>
<td></td>
<td></td>
<?php if ($rows ['Payment Status'] == 'Paid') {?>
<td align="center"><input type="checkbox" id="paid" class="paid" name="paid" checked></td>
<?php } else { ?>
<td align="center"><input type="checkbox" id="paid" class="paid" name="paid"></td>
<?php } ?>
<td></td>
</tr>
<?php

修改了php out以显示一个选中的值,该值将被禁用。
$(document).ready(function() {
// add row class, avoid headers
$('#billing_table tr.row').each(function() {
var checked = $(this).find(".billed-select").find("option:selected").val();
console.log("checked:",checked);// alerts 0
$(this).find('.paid').prop('disabled', (checked != "1"));
});
});
