防止laravel link_to_action双击执行 [英] prevent laravel link_to_action to perform on double click

问题描述

在我的laravel项目负责人中，我编写了一个用于批准和拒绝约会的代码.拒绝约会后，该条目将从数据库中删除，并再次重定向到列表.

In my laravel project controller i wrote a code for approve and reject appointments. on rejecting the appointment the entry will be deleted from database and redirect again to the listing table.

我在拒绝部分使用了此代码

i used this code in reject section

html_entity_decode(link_to_action('AdminController@getAtoggle', '<img src="'.$icon2.'"alt=asknow width=20 height=20/>',array($data['appointment_id'],2),array('title'=>'Click Me For Reject','ondblclick' => "event.preventDefault();")));

但是当双击" Trying to get property of non-object "时仍显示错误.我很清楚这是因为，第一次单击时，该条目已从数据库中删除，因此第二次单击时，没有要删除的条目在db中.但是如果用户双击我不想向他们显示此错误消息或404页面.

But still when double clicks " Trying to get property of non-object " error is showing. I clearly know this occurs because , on first click the entry is deleted from database so the second click there is no entry to delete in db. but in case the user double clicks i don't want to show them this error message or 404 page.

有什么办法可以防止双击.我在"ondblclick"中尝试了"alert"，但这同时显示了警报和错误页面.

so is there any way to prevent double clicks. i tried "alert" in "ondblclick" but that shows both alert and error page.

推荐答案

我认为问题在于您正在尝试使用event进行初始化.

I think the problem is you're trying to use event before it's been initialised.

尝试将代码从<a>标记移至JS文件，尝试使用此jQuery

Try move the code from the <a> tag to your JS files, try this jQuery

$( "#target" ).dblclick(function(event) {
  event.preventDefault();
});

我将event传递到回调中，以便您可以运行preventDefault().

I'm passing in event into the callback so you can run preventDefault().
