Example code for jQuery to realize random dragging of divs (general code)_jquery

Pay attention to the location where js is placed. It should be placed close to it. If it is covered by others, it cannot be moved.

For example:

<div id="move">可移动的DIV</div>

Introduce jquery.js, jquery-ui.js,

<script scr="http://code.jquery.com/jquery-1.10.2.js"></script>
<script scr="http://code.jquery.com/ui/1.11.4/jquery-ui.js"></script>

One sentence:

$("#move").draggable();

If you wish, the mouse will change into a hand shape when you click and hold:

$("#move").mousedown(function(){
$(this).css("cursor","pointer");
}).mouseup(function(){
$(this).css("cursor","default");
});

Let me share with you a common code jquery to implement a common method of dragging divs

<script type="text/javascript"><!-- 
$(document).ready(function() 
{ 
$(".show").mousedown(function(e)//e鼠标事件 
{ 
$(this).css("cursor","move");//改变鼠标指针的形状 
var offset = $(this).offset();//DIV在页面的位置 
var x = e.pageX - offset.left;//获得鼠标指针离DIV元素左边界的距离 
var y = e.pageY - offset.top;//获得鼠标指针离DIV元素上边界的距离 
$(document).bind("mousemove",function(ev)//绑定鼠标的移动事件，因为光标在DIV元素外面也要有效果，所以要用doucment的事件，而不用DIV元素的事件 
{ 
$(".show").stop();//加上这个之后 
var _x = ev.pageX - x;//获得X轴方向移动的值 
var _y = ev.pageY - y;//获得Y轴方向移动的值 
$(".show").animate({left:_x+"px",top:_y+"px"},10); 
}); 
}); 
$(document).mouseup(function() 
{ 
$(".show").css("cursor","default"); 
$(this).unbind("mousemove"); 
}) 
}) 
// --></script>
