本文介绍了yii:如何在运行提交按钮之前运行一个函数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我需要在 yii 1.1.X 中运行提交按钮之前运行一个函数
我的函数是这种形式的getcode()
这是我在 _form.php
中的代码
我想从这个函数中设置(组文本文件)的值
<div class="form"><?php $form=$this->beginWidget('CActiveForm', array('id'='=>'文本形式','enableAjaxValidation'=>TRUE,'focus'=>array($model,'group'),//'clientOptions'=>array(//'validateOnChange'=>true,//默认值.输入更改时验证//'validateOnType'=>'true',//每次击键都验证，万岁！//'validationDelay'=>10,//与这篇文章无关——但是很酷！////默认延迟为 200 毫秒//),));?><p class="note">带有 <span class="required">*</span> 的字段</p><?php echo $form->errorSummary($model);?><div class="row"><?php echo $form->labelEx($model,'subject');?><?php echo $form->textField($model,'subject',array('size'=>60,'maxlength'=>80));?><?php echo $form->error($model,'subject');?>
<div class="row"><?php echo $form->labelEx($model,'matn');?><?php echo $form->textField($model,'matn',array('size'=>60,'maxlength'=>255));?><?php echo $form->error($model,'matn');?>
<div class="row"><?php echo $form->labelEx($model,'group');?><?php echo $form->textField($model,'group',array('value'=>$groupNumber, 'size'=>20,'maxlength'=>20));?><?php echo $form->error($model,'group');?>
<?php $userX=yii::app()->session['idX'];?><div class="row"><?php//echo $form->labelEx($model,'user_id');?><?php echo $form->textField($model,'user_id',array('value'=>$userX,'type'=>"hidden"));?><?php//echo $form->error($model,'user_id');?>
<div class="row"><?php echo $form->labelEx($model,'Privacy');?><?php echo $form->dropDownList($model,'Privacy', array('1'=>'Public','2'=>'Only me'));?><?php echo $form->error($model,'Privacy');?>
<div class="行按钮"><?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save' );?>
<?php $this->endWidget();?></div><!-- 形式--><?php函数getcode(){$groupNumber =Text::model()->maxIdNote();}
如何在保存表单之前运行此功能.
这是我的文本模型

解决方案
试试这个(请替换必填值，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') );?>
在视图文件末尾写这个 -
在文本控制器中 -
创建一个新动作(与替换ACTION_NAME时提到的相同)-
公共函数 actionACTION_NAME() {$groupNumber = Text::model()->maxIdNote();回声 json_encode($groupNumber);出口();}
i need run a function before run submit button in yii 1.1.X
my function is getcode() in this form
this is my code in _form.php
i want set value of ( group textfiled ) from this function

// // default delay is 200 ms
// ),
)); ?>

解决方案
Try this (please replace the required values, especially ACTION_NAME) -
Change in view file -
<?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save' ); ?>
to
<?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save', array('id' => 'text_form_submit') ); ?>
Write this at the end of the view file -
<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>
In TextController -
Create a new action (same as what is mentioned in replacement to ACTION_NAME) -
public function actionACTION_NAME() {
$groupNumber = Text::model()->maxIdNote();
echo json_encode($groupNumber);
exit();
}
