Assign values ​​to multiple spans through jquery after the page is loaded

Since I want to display the current time in several places after the page is loaded, I need to assign values ​​to multiple spans.

The span code is written as follows: 

<span name="currentDate"></span> （多个span）

jQuery writing: 

<script> 
$(document).ready(function() { 
var currentDate = new Date().toLocaleDateString(); 
$("span[name='currentDate']").each(function() { 
$(this).text(currentDate); 
}); 
}); 
</script>
