我需要在yii 1.1.X
中运行提交按钮之前运行一个函数我的函数是getcode()，格式为
这是我在 _form.php
中的代码我希望从此函数中设置（group textfiled）

/* @var $model Text */
/* @var $form CActiveForm */
?>
<div class="form">
<?php $form=$this->beginWidget('CActiveForm', array(

// 'validateOnType'=>'true', // validate with EVERY keystroke, hooray!
// 'validationDelay'=>10, // not related to this post--but cool!
// // default delay is 200 ms
// ),
)); ?>
<p class="note">Fields with <span class="required">*</span> are required.</p>
<?php echo $form->errorSummary($model); ?>

试试这个（请替换所需的值，尤其是ACTION_NAME） -
更改视图文件 -
<?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save' ); ?>
到
<?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save', array('id' => 'text_form_submit') ); ?>
将此内容写在视图文件的末尾 -
<script>
$(document).ready(function() {
$('#text_form_submit').click(function(ev) {
ev.preventDefault();
$.ajax({
type: 'GET',
dataType: 'JSON',
url: '<?php echo Yii::app()->createUrl("text/ACTION_NAME"); ?>',
success:function(data){
if(data !== null) {
$('#Text_group').val(data);
$('#text-form').submit();
}
},
error: function() {
alert("Error occured!!!.");
},
});
return false;
});
});
</script>
在TextController中 -
创建一个新动作（与ACTION_NAME替代的内容相同） -
public function actionACTION_NAME() {
$groupNumber = Text::model()->maxIdNote();
echo json_encode($groupNumber);
exit();
}
