我有一个 MySQL 表和模型 patient_entry，其中包含字段 patient_name、city 和 state.我还有另一个表/模型 health_card，它也包含 patient_name、city 和 state.
I have a MySQL table and model patient_entry which contains fields patient_name, city and state. I also have another table/model health_card which also contains patient_name, city and state.
假设 patient_entry 表已经填充了 patient_name、city 和 state.
Suppose the patient_entry table is already filled with patient_name, city and state.
当我在 health_card 表单中输入数据时，当我通过与 patient_entry 表相关的下拉字段选择 patient_name 时，我想要要自动填充的相关 city 和 state 字段.
When I am entering data in health_card form, when I select the patient_name via drop-down field related to patient_entry table, I want the related city and state fields to be auto-filled.
我用于 health_card 的 _form.php 看起来像这样:
My _form.php for health_card looks like this:
<head>
<script>
$this->registerJs("$('#healthcard-patient_name').on('change',function(){
$.ajax({
url: '".yiihelpersUrl::toRoute("HealthCard/patient")."',
dataType: 'json',
method: 'GET',
data: {id: $(this).val()},
success: function (data, textStatus, jqXHR) {
$('#healthcard-city').val(data.city);
$('#healthcard-pincode').val(data.pin);
},
beforeSend: function (xhr) {
alert('loading!');
},
error: function (jqXHR, textStatus, errorThrown) {
console.log('An error occured!');
alert('Error in ajax request');
}
});
});");
</script>
</head>
并且在我添加的控制器中，根据建议，这个:
And in the controller I have added, as per the suggestion, this:
public function actionPatient($id){
// you may need to check whether the entered ID is valid or not
$model= appmodelsPatientEntry::findOne(['id'=>$id]);
return yiihelpersJson::encode([
'city'=>$model->disrict_city,
'pin'=>$model->pin_code
]);
}
您所需要的只是调用 AJAX 请求来获取所需的字段.就像下面这样:
All you need is calling an AJAX request to get needed fields. Just act like below:
(我不知道你的型号名称)看看你的表格，看看你的 patient_name 字段的 id 是什么.它通常是 modelname-fieldname.我假设您的模型名称是 Patient.因此，patient_name 的 id 将是 patient-patient_name.
(I do not know your model name)take a look at your form and see what is the id of your patient_name field. It is usually modelname-fieldname. I assume that your model name is Patient. So, the id of patient_name would be patient-patient_name.
添加 ajax 请求(在您看来).
Add an ajax request (in your view).
调用 AJAX 的代码可能如下所示:
The code for calling AJAX could look just like below:
$this->registerJs("$('#patient-patient_name').on('change',function(){
$.ajax({
url: '".yiihelpersUrl::toRoute("controllerName/patient")."',
dataType: 'json',
method: 'GET',
data: {id: $(this).val()},
success: function (data, textStatus, jqXHR) {
$('#patient-city').val(data.city);
$('#patient-state').val(data.state);
},
beforeSend: function (xhr) {
alert('loading!');
},
error: function (jqXHR, textStatus, errorThrown) {
console.log('An error occured!');
alert('Error in ajax request');
}
});
});");
注意事项:
city 和 state 字段的 id 具有以下 id(s):patient-city 和 state-city 相对.我没有考虑代码清理的任何条件.请确保用户数据正确.
city and state fields has the following id(s): patient-city and state-city relatively. I didn't consider any conditions for code cleaning. Please make sure that user data is correct.
操作代码:
public function actionPatient($id){
// you may need to check whether the entered ID is valid or not
$model= appmodelsPatient::findOne(['id'=>$id]);
return yiihelpersJson::encode([
'city'=>$model->city,
'state'=>$model->state
]);
}
