Question

我尝试创建searchMap（）函数，并在搜索按钮点击事件中调用它，但它不起作用并给我以下错误：

Uncaught ReferenceError: searchMap is not defined

我无法解释代码的问题

这是视图文件的代码

    <?php
/* @var $this EventListController */
/* @var $model EventList */
/* @var $form CActiveForm */
?>
<script  type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script>
<?php  $baseUrl = Yii::app()->baseUrl;  $cs = Yii::app()->getClientScript(); $cs->registerScriptFile($baseUrl.'/js/gmaps.js',CClientScript::POS_END ); ?>

<div class="form">
<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'event-list-form',
    // Please note: When you enable ajax validation, make sure the corresponding
    // controller action is handling ajax validation correctly.
    // There is a call to performAjaxValidation() commented in generated controller code.
    // See class documentation of CActiveForm for details on this.
     'enableAjaxValidation'=>true,   
        'htmlOptions' => array('enctype' => 'multipart/form-data'),

您没有向CClientScript::registerScript提供$position参数。默认情况下，Yii将JavaScript代码的加载推迟到CClientScript::POS_READY，其中：

脚本插入到jQuery的ready函数中。

您的onclick处理程序正在全局范围内查找命名函数;而Yii已经将你的脚本置于jQuery的准备状态（可能在匿名函数中）。

您有两种选择：

将$position设为CClientScript::POS_HEAD或CClientScript::POS_BEGIN。（注意：这不是最理想的，因为它可以在加载jQuery之前触发。也就是说，$尚未定义。）

删除onclick处理程序并使用jQuery绑定事件，例如：

向id元素添加input属性：

<input type="button" class="btn" value="Search" id="search_map" />

使用jQuery的on：

$('#search_map').on('click', function(){
    alert($('#address').val());
});

Yii - js功能不起作用
