javascript確認框問題

Question

我在此鏈接上使用了確認框

<a href="<?php echo Yii::$app->params["url"]; ?>admin/index/deletcompany&companyid=<?php echo $Companydata['company_id']; ?>&userid=<?php echo $userid; ?>" id="<?php echo $Companydata['company_id']; ?>" onclick="confirmdialog()"><span class="glyphicon glyphicon-trash" title="Delete"></span></a>

JavaScript代碼

function confirmdialog(e){
     var r=confirm("Are you sure you want to delete this company?");
        if(r == true)
        {

         return true;
        }
        else
        {
         return false;
      }     

    }  

但是每執行一次案例操作，然后單擊“取消”。請給我我的問題。

Answer 1

不使用Onclick事件和自定義函數：

<a href="javascript:if(confirm('Are you sure you want to delete this company?')){ window.location='<?php echo Yii::$app->params["url"]; ?>admin/index/deletcompany&companyid=<?php echo $Companydata['company_id']; ?>&userid=<?php echo $userid; ?>'; };" id="<?php echo $Companydata['company_id']; ?>"><span class="glyphicon glyphicon-trash" title="Delete"></span></a>

通過將自定義函數用於Onclick事件：

<a href="<?php echo Yii::$app->params["url"]; ?>admin/index/deletcompany&companyid=<?php echo $Companydata['company_id']; ?>&userid=<?php echo $userid; ?>" id="<?php echo $Companydata['company_id']; ?>" onclick="return confirmdialog();"><span class="glyphicon glyphicon-trash" title="Delete"></span></a>

<script type="text/javascript">
    function confirmdialog(){
        return confirm('Are you sure you want to delete this company?');
    }
</script>

通過使用JQuery：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>

<a class="my_anchors" href="<?php echo Yii::$app->params["url"]; ?>admin/index/deletcompany&companyid=<?php echo $Companydata['company_id']; ?>&userid=<?php echo $userid; ?>" id="<?php echo $Companydata['company_id']; ?>"><span class="glyphicon glyphicon-trash" title="Delete"></span></a>

    <script type="text/javascript">
    $(document).ready(function(){
        $( ".my_anchors" ).click(function() {
          return confirm('Are you sure you want to delete this company?');
        });
    });
    </script>

Answer 2

試試這個html onclick="return confirmdialog()"

<a href="delete.php" onclick="return confirmdialog()">delete</a>

和js

function confirmdialog(e){
 if(!confirm("Are you sure you want to delete this company?"){
     return false;
  }     

}
