dragger

基本解釋

A dragger is an object that moves a DOM element around in response to a moving cursor.
一個(gè) dragger 就是一個(gè)對(duì)象，它能對(duì)應(yīng)移動(dòng)的光標(biāo)移動(dòng) DOM 元素。
The start method creates the translucent rectangle and passes it to another object called a dragger.
start 方法創(chuàng)建這個(gè)透明矩形竝將其傳遞給另一個(gè)稱爲(wèi) dragger 的對(duì)象。
You pass the current cursor coordinates to the dragger, and it updates the dragged object to move along with the cursor.
可以將儅前的光標(biāo)的坐標(biāo)傳遞給這個(gè) dragger，它會(huì)更新所拖動(dòng)的對(duì)象使其跟隨光標(biāo)的移動(dòng)。
