我正在尝试基于pdo-query生成的单选输入标签禁用和启用选择字段,但无法正确执行。
select字段确实被prop('disabled',true)禁用,但转回启用状态无效。 (代码中注释块中的示例标签列表)
我尝试了各种方法,例如onClick,onChange等,但这些方法似乎均未达到预期的效果。我还在这里搜索了有关此问题的各种主题,但所有这些主题显然都在使用无线电输入本身并提供了具体的选择。例如,其中一个是我之前咨询过的线程
Enable/Disable a button on select of radio button in jquery
我的情况是我有一个带有动态标签的不确定无线电输入域,所以我不能使用像if (val = this || val = that)
请参考以下代码和我期望的解决方案
<form name='enter_slip_data' action='submitPatData.php' method='post' class='needs-validation' novalidate>
<div class='form-group'>
<select name='doctor_name' id='doctor_name_id' class='custom-select' required>
<option selected disabled value=''>Select Doctor</option>
<!-- function below will print options of doctor names fetched from database -->
<?php echo getDocNameList(); ?>
</select>
</div>
<div class='form-group'>
<input type='text' name='patient_name' class='form-control' placeholder='Enter Patient Name' required/>
</div>
<div class='form-group'>
<input type='text' name='patient_telephone' class='form-control' placeholder='Enter Patient Telephone' required/>
</div>
<div class='form-group'>
<input type='text' name='patient_address' class='form-control' placeholder='Enter Patient Address' required/>
</div>
<div class='form-group'>
<input type='text' name='patient_age' class='form-control' placeholder='Enter Patient Age' required/>
</div>
<div class='form-group'>
<select name='patient_gender' class='custom-select' required>
<option selected disabled>Select Gender</option>
<option value='male'>Male</option>
<option value='female'>FeMale</option>
</select>
</div>
<div class='form-group'>
<div class='btn-group btn-group-toggle' style='flex-flow: row wrap;border-radius:5px;overflow:hidden;' data-toggle='buttons'>
<?php
/* function below will fetch records from database and print labels with radio inputs
These inputs could be of any number with at least one of them named 'Drip Case'
i-e-
------------------------------------------------------
| Drip Case | Histatmy | Sk. Stitch | LSCS | ND & DNC |
------------------------------------------------------
Clicking on drip case disables the above select box
Clicking on any other label should enable it back

function getOperationList(){
global $db;
$getOPType = $db->prepare("SELECT * from operation_types");
$getOPType->execute();
$opType = '';
if($getOPType->rowCount() > 0){
while($showOpTypes = $getOPType->fetch(PDO::FETCH_ASSOC)){
$opType .= "<label id='opType_label'class='btn btn-secondary success' style='border-radius:0;'>";
$opType .= "<input type='radio' id='op_type' name='op_type' value='".$showOpTypes['id']."' autocomplete='off'>" . $showOpTypes['name'];
$opType .= "</label>";
}
return $opType;
}
}
?>
</div>
</div>
<div class='form-group'>
<input type='text' name='patient_fee' class='form-control' placeholder='Enter Fees' required/>
</div>
<div class='form-group'>
<input type='hidden' name='dept' id='dept' value='Operation' />
<input type='hidden' name='test_type' value='2' />
<button type='button' class='btn btn-secondary' disabled><?php echo getReciptNo(); ?></button>
<button type='submit' name='submitPatData' class='btn btn-secondary' value='Print Recipt'>Print Recipt</button>
<button type='button' class='btn btn-danger' data-dismiss='modal'>Cancel</button>
</div>
</form>
我现在要使用的jQuery代码是
$('#opType_label').click(function(){
if($(this).text() == 'Drip Case'){
$('#doctor_name_id').prop("selectedIndex", 0);
$('#doctor_name_id').prop("disabled", true);
} else {
$('#doctor_name_id').prop("disabled",false);
}
});
使用上面的代码,我可以在单击Drip-Case
标签时禁用选择框,但是当我单击任何其他预期效果的标签时,都不会启用选择框
答案 0 :(得分:0)
我看到的最大问题是,您为每个单选标签使用了#opType_label ID。您每个人都需要一个唯一的ID或使用一个类。-DanielG
正如丹尼尔(Daniel)所述,我使用了类而不是od ID,它现在可以正常工作。
while($showOpTypes = $getOPType->fetch(PDO::FETCH_ASSOC)){
$opType .= "<label id='opType_label'class='btn btn-secondary success opType' style='border-radius:0;'>";
$opType .= "<input type='radio' id='op_type' name='op_type' value='".$showOpTypes['id']."' autocomplete='off'>" . $showOpTypes['name'];
$opType .= "</label>";
}
$('.opType').click(function(){
if($(this).text() == 'Drip Case'){
$('#doctor_name_id').prop("selectedIndex", 0);
$('#doctor_name_id').prop("disabled", true);
} else {
$('#doctor_name_id').prop("disabled",false);
}
});
