在div上使用拖放和旋转

你好，我需要你把旋转以及拖放到一个单独的div ..我试过下面的代码，但只有当表单加载后，我可以拖放它被禁用。我可以在任何时候旋转，但无法拖放...请帮助！在div上使用拖放和旋转

<style> 
    #mainTarget{ 
width:300px; 
height:200px; 
position:relative; 
top:100px; 
left:25% 
} 

.mainTarget{position:absolute; width:300px; height:200px;} 

#target{ 
position:absolute; 
height:20px; 
width:20px; 
background:url(http://files.softicons.com/download/system-icons/human-o2-icons-by-oliver-scholtz/png/128x128/actions/object-rotate-left.png) no-repeat top center #ffffff; 
background-size:100%; 
cursor:pointer; 
z-index:1; 
top:0; 
right:0;  
} 
#target1{ 
position:absolute; 
height:20px; 
width:20px; 
background:url(http://files.softicons.com/download/system-icons/human-o2-icons-by-oliver-scholtz/png/128x128/actions/object-rotate-left.png) no-repeat top center #ffffff; 
background-size:100%; 
cursor:pointer; 
z-index:1; 
bottom:0; 
left:0;  
} 

    #mainTarget1{ 

width:320px; 
height:200px; 
position:relative; 

} 

    .mainTarget1{position:absolute; width:300px; height:200px;}

你最好重写JS。重新开始并为图像定义两个容器 - 一个用于旋转，另一个用于应用翻译。此外，如果你打算使用jQueryUI可拖拽并且坚持这一点。下面是一个简单的示例使用从您的代码并没有jQuery UI的唯一事件鼠标的位置，并纳入两个集装箱的想法（在所有不精）：

var dragging = false; 
var rotating = false; 
var target = $('#target'); 
var target1 = $('#target1'); 
var mainTarget = $('#mainTarget'); 
var mainTarget1 = $('#mainTarget1'); 
var rad = mainTarget.width()/2; 
var elOfs = $('.mainTarget').offset(); 
var elPos = { 
     x: elOfs.left, 
     y: elOfs.top 
} 
target.mousedown(function() {; 
     dragging = false; 
     rotating = true; 
}); 
$(".mainTarget").mousedown(function (a) { 
     dragging = true; 
     rotating = false; 
}); 
$(document).mouseup(function (a) { 
     dragging = (dragging) ? false : dragging; 
     rotating = (rotating) ? false : rotating;  
}); 
$(document).mousemove(function (e) { 
     var mPos = { 
      x: e.pageX - elPos.x, 
      y: e.pageY - elPos.y 
     }; 
     var getAtan = Math.atan2(mPos.x - rad, mPos.y - rad); 
     var getDeg = -getAtan/(Math.PI/180) + 135; //135 = (180deg-45deg) 
     $('p').text(getDeg); 
     var style_position = $("#mainTarget").attr("style");  
     $("#style").val(style_position); 
     if (rotating) { 
      $('#rotate').css({ 
       transform: 'rotate(' + getDeg + 'deg)' 
      }); 
     } 
     if (dragging) { 
      mainTarget.css({ 
       transform: 'translate(' + mPos.x + 'px,' + mPos.y + 'px)' 
      }); 
     } 

});

这里是HTML：

<p>degrees</p> <span> rotate</span> 

<input type="text" id="style" name="style" /> 
<div id="mainTarget"> 
    <div id="rotate"> 
     <img src="http://www.joomlaworks.net/images/demos/galleries/abstract/7.jpg" width="300" class="mainTarget" /> 
     <div id="target">&nbsp;</div> 
    </div> 
</div>

和一个新的CSS规则：

#rotate{ 
    position:relative; 
    width:300px; 
    height:200px; 
}

here is the fiddle
