JS button button implements submit button submission effect

When using the form today, I used POST update and delete operations at the same time. However, the submit form will be all submitted once it is submitted, so the implementation method that comes to mind is to use button implementation. The code implementation is as follows:

Form settings:

<form method=”post” name=”linkform”>

Hidden act method settings, the code is as follows:

<input name=”act” type=”hidden” />

The last key is the setting of the button, the update button, the code is as follows:

<input onclick=”document.linkform.act.value='update'; document.linkform.submit();” name=”update” type=”button” value=”更新” />

Delete button, the code is as follows:

<input onclick=”if(confirm(‘你确定要删除数据吗？')){ document.linkform.act.value='delete'; document.linkform.submit();return true;}return false; ” type=”button” value=”删除” />

The above is the JS that the editor introduces to you The button button implements the submit button submission effect
