Question

您好我在我的项目中使用jquery resizable，rotate（）[https://cdn.jsdelivr.net/gh/godswearhats/jquery-ui-rotatable@1.1/jquery.ui.rotatable.min.js]。

所以当这个函数调用i得到句柄来旋转和调整div的大小。

$( function() {

        var inputLocalFont = document.getElementById("user_file");
        inputLocalFont.addEventListener("change",previewImages,false);

        function previewImages(){
            var fileList = this.files;

            var anyWindow = window.URL || window.webkitURL;

                for(var i = 0; i < fileList.length; i++){
                  var objectUrl = anyWindow.createObjectURL(fileList[i]);
                  $('.new-multiple').append('<div class="img-div"><img src="' + objectUrl + '" class="newly-added" /></div>');
                  window.URL.revokeObjectURL(fileList[i]);
                }

        $( ".img-div" ).draggable();
	      $('.img-div').rotatable();
        $( ".img-div" ).resizable({aspectRatio:true});
              $(".newly-added").on("click", function(e) {
	   $(".newly-added").removeClass("img-selected");
       $(this).addClass("img-selected");
	    e.stopPropagation()
    });

	  $(document).on("click", function(e) {
		if ($(e.target).is(".newly-added") === false) {
		  $(".newly-added").removeClass("img-selected");
		}
	  });
              
              } 
});

.new-multiple{
  width:400px !important;
  height:400px !important;
  background:white;
  border:2px solid red;
  overflow:hidden;
  }
  
  
 .img-div{
   width:200px;
   height:200px;
 } 
 .newly-added{
    width:100%;
    height:100%;
} 

.img-selected{
  box-shadow: 1px 2px 6px 6px rgb(206, 206, 206);
  border:2px solid rgb(145, 44, 94);
}
.ui-resizable-handle.ui-resizable-se.ui-icon.ui-icon-gripsmall-diagonal-se {
    background-color: white;
    border: 1px solid tomato;
}
.ui-rotatable-handle.ui-draggable {
    background-color: white !important;
    border: 1px solid tomato;
}

 <div class="new-multiple"></div>

因此，当我上传图片时，我会得到像这样的控制句柄

但我想放置像这样的自定义控件句柄

我如何使用css和jquery实现这一目标。请帮忙

在resizable中设置<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.4/lodash.min.js"></script>选项后，您可以使用CSS管理它们。他们的风格和位置。

.ui-resizable-handle {
  border: 0;
  border-radius: 50%;
  background-color: #00CCff;

}

.ui-resizable-nw {
  top: -7px;

.ui-resizable-ne {

.ui-resizable-e {

.ui-resizable-sw {

.ui-resizable-se {

.ui-resizable-se.ui-icon {

.ui-rotatable-handle {
  background-size: 14px;
  background-repeat: no-repeat;
  background-position: center;
  border: 0;
  border-radius: 50%;
  background-color: #00CCff;
