How to lock touch in thinkphp

With the development of mobile Internet, more and more websites need to adapt to mobile phones and achieve responsive layout. In this process, the processing of touch events has become an essential link. In ThinkPHP development, how to lock touch is an issue that everyone is more concerned about.

1. What is a touch event?

Touch events refer to the user’s behavior of operating by touching the phone screen. For example, tap, slide, long press and other operations.

In WEB development, touch events also need to be processed to achieve interaction with users. For example, when a user taps a button, the corresponding operation will be triggered.

2. How does ThinkPHP handle touch events?

In ThinkPHP, handling touch events is similar to how other events are handled. Capture touch events by using JavaScript on the view and then send a request to the server for processing.

The following is a simple example of using jQuery to capture touch events:

<script type="text/javascript">

$('#button').on('touchstart', function(e){

    e.preventDefault();//阻止默认行为

    var id = $(this).attr('data-id');//获取按钮ID

    $.ajax({

        url:'处理触摸事件的地址',//处理触摸事件的地址

        type:'POST',

        data:{'id':id},//传递参数

        success:function(data){

            //处理返回结果

        }

    });

});

</script>

In the above code, jQuery's touchstart event is used to capture the touch event of the button and send it to the button through Ajax. The server sent the request. On the server side, we need to write corresponding processing code to respond to this request.

3. How to lock touch?

Since touch events are feedback from the user's active behavior, if the user operates frequently, it may cause the system to respond slowly or crash. Therefore, sometimes it is necessary to lock the touch of a certain area to limit the user's operation range.

In ThinkPHP, we can lock touch events through CSS styles. By adding the style pointer-events:none to an element, you can prevent that element from receiving touch events. For example, the following code:

<div class="box" style="pointer-events:none;">该区域被锁定，不能触摸</div>

In the above code, the style pointer-events:none is added to the div element of the box class, and the element cannot respond to touch events.

4. Summary

The above is an introduction to how to handle touch events and how to lock touches. In website development, the processing of touch events is inevitable, and the corresponding technical solution needs to be selected according to specific needs. At the same time, in order to improve user experience and ensure system stability, proper locking of touch operations is also necessary.
