用于抓取游标的CSS(拖放)

Question

我有一个JavaScript webapp,用户需要抓住背景来移动整个屏幕.所以我希望光标在它们悬停在背景上时发生变化.在-moz-grab和-moz-grabbingCSS光标是非常理想的.当然,它们只适用于Firefox ...其他浏览器是否有相同的游标？我是否必须做一些比标准CSS游标更自定义的东西？

Answer 1

如果其他人偶然发现这个问题,这可能就是您所寻找的:

.grabbable {
    cursor: move; /* fallback if grab cursor is unsupported */
    cursor: grab;
    cursor: -moz-grab;
    cursor: -webkit-grab;
}

 /* (Optional) Apply a "closed-hand" cursor during drag operation. */
.grabbable:active {
    cursor: grabbing;
    cursor: -moz-grabbing;
    cursor: -webkit-grabbing;
}

Answer 2

我认为move可能是你正在做的最接近的标准光标值:

move
表示要移动的东西.

Answer 3

CSS3 grab和grabbing现在允许值cursor.为了提供跨浏览器兼容性的几个回退,包括自定义游标文件,完整的解决方案如下所示:

.draggable {
    cursor: move; /* fallback: no `url()` support or images disabled */
    cursor: url(images/grab.cur); /* fallback: Internet Explorer */
    cursor: -webkit-grab; /* Chrome 1-21, Safari 4+ */
    cursor:    -moz-grab; /* Firefox 1.5-26 */
    cursor:         grab; /* W3C standards syntax, should come least */
}

.draggable:active {
    cursor: url(images/grabbing.cur);
    cursor: -webkit-grabbing;
    cursor:    -moz-grabbing;
    cursor:         grabbing;
}

Answer 4

比CSS游标更"自定义"意味着某种类型的插件,但您可以使用CSS完全指定自己的游标.我认为这个列表有你想要的:

.alias {cursor: alias;}
.all-scroll {cursor: all-scroll;}
.auto {cursor: auto;}
.cell {cursor: cell;}
.context-menu {cursor: context-menu;}
.col-resize {cursor: col-resize;}
.copy {cursor: copy;}
.crosshair {cursor: crosshair;}
.default {cursor: default;}
.e-resize {cursor: e-resize;}
.ew-resize {cursor: ew-resize;}
.grab {cursor: grab;}
.grabbing {cursor: grabbing;}
.help {cursor: help;}
.move {cursor: move;}
.n-resize {cursor: n-resize;}
.ne-resize {cursor: ne-resize;}
.nesw-resize {cursor: nesw-resize;}
.ns-resize {cursor: ns-resize;}
.nw-resize {cursor: nw-resize;}
.nwse-resize {cursor: nwse-resize;}
.no-drop {cursor: no-drop;}
.none {cursor: none;}
.not-allowed {cursor: not-allowed;}
.pointer {cursor: pointer;}
.progress {cursor: progress;}
.row-resize {cursor: row-resize;}
.s-resize {cursor: s-resize;}
.se-resize {cursor: se-resize;}
.sw-resize {cursor: sw-resize;}
.text {cursor: text;}
.url {cursor: url(https://www.w3schools.com/cssref/myBall.cur),auto;}
.w-resize {cursor: w-resize;}
.wait {cursor: wait;}
.zoom-in {cursor: zoom-in;}
.zoom-out {cursor: zoom-out;}

Answer 5

您可以使用创建自己的游标并将其设置为光标cursor: url('path-to-your-cursor');,或者找到Firefox并复制它们(奖励:在每个浏览器中都有一个很好的一致性).

Answer 6

我可能来晚了，但是您可以尝试下面的代码，该代码对我的拖放有效。

.dndclass{
    cursor: url('../images/grab1.png'), auto; 

}

.dndclass:active {
    cursor: url('../images/grabbing1.png'), auto;
}

您可以在上面的URL中使用下面的图像。确保它是PNG透明图像。如果没有，请从Google下载一个。
