$（'< some element here>' ）.on（'dragstart'，function（）{
 $（this）.css（cursor，move）; 
}）; 
 

但是，这将永久地更改元素上的光标，以切换此光标更改添加

  $（'< some element here>'）on（'dragend'，function（）{
 $ ）.css（cursor，default）; //或任何要还原到
}的指针）; 
 

I want to change the cursor when dragging, so I try this way:

function drag (event) {

    localStorage.setItem("no", $(event.target).data("no"));

    $("html").css("cursor", "move");

}

<tr draggable="true" class="memo_item move" id="memo_<?php echo $memo->memo_no?>" ondragstart="drag(event, this);" data-no="<?php echo $memo->memo_no?>"></tr>

but it doesn't work.

And I can't use JQueryUi.

How can I change cursor?

Simply implement this kind of event setup in your code...

$('<some element here>').on('dragstart', function() {
  $(this).css("cursor", "move");
});

However, this will permanently change the cursor on the element, to toggle this cursor change add

$('<some element here>').on('dragend', function() {
  $(this).css("cursor", "default"); // or whatever pointer you want to revert to
});
