如何在Yii页面上将JavaScript与CHtml button（）一起使用

Question

I'm trying to use JavaScript in my page. My JavaScript code is:

function edit(){
  alert("test"); 
  return document.getElementById("confirm").value="";
}

Calling this, by onclick function

<?php echo CHtml::button("Edit",array('title'=>"Edit",'onclick'=>'js:edit();')); ?>

both where in same page and confirmation.php

Answer 1

Yii::app()->clientScript->registerScript('register_script_name', "
    $('#editButton').click(function(){
       alert('edit');
       return false;
    });
", CClientScript::POS_READY);

<?php echo CHtml::button("Edit",array('title'=>"Edit",'id'=>"editButton")); ?>

Answer 2

Set an ID for your button:

<?php echo CHtml::button("Edit",array('title'=>"Edit",'id'=>'myButton')); ?>

JS:

window.onload = function() {
    document.getElementById("myButton").onclick = function() {
        alert("test");
        document.getElementById("confirm").value = "";
        return false;
    }
}

Or you can just remove the js: part from your code:

<?php echo CHtml::button("Edit",array('title'=>"Edit",'onclick'=>'edit()')); ?>
