使用CSS在div周围自定义叠加层-jQuery可调整大小的自定义句柄

Question

Hi i am using jquery resizable, rotatable() [ https://cdn.jsdelivr.net/gh/godswearhats/jquery-ui-rotatable@1.1/jquery.ui.rotatable.min.js] in my project .

So when this function called i get handles to rotate and resize the div.

 $( 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; }

When you set the handles option in resizable, you can then manage them with CSS. Their style and location.

CSS Snippet

.ui-resizable-handle {
  border: 0;
  border-radius: 50%;
  background-color: #00CCff;
  width: 14px;
  height: 14px;
}

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

.ui-resizable-ne {
  top: -7px;
  right: -7px;
}

.ui-resizable-e {
  top: calc(50% - 7px);
  right: -7px;
}

.ui-resizable-w {
  top: calc(50% - 7px);
  left: -7px;
}

.ui-resizable-sw {
  bottom: -7px;
  left: -7px;
}

.ui-resizable-se {
  right: -7px;
  bottom: -7px;
}

.ui-resizable-se.ui-icon {
  display: none;
}

.ui-rotatable-handle {
  background-size: 14px;
  background-repeat: no-repeat;
  background-position: center;
  border: 0;
  border-radius: 50%;
  background-color: #00CCff;
  margin-left: calc(50% - 9px);
  bottom: -5px;
  width: 18px;
  height: 18px;
}

JavaScript

$(function() {
  var inputLocalFont = $("#user_file");
  inputLocalFont.change(previewImages);

  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]);
      var $newDiv = $("<div>", {
        class: "img-div"
      });
      var $newImg = $("<img>", {
        src: objectUrl,
        class: "newly-added"
      }).appendTo($newDiv);
      $(".new-multiple").append($newDiv);
      $newDiv.draggable();
      $newDiv.rotatable();
      $newDiv.resizable({
        aspectRatio: true,
        handles: "ne, nw, e, se, sw, w"
      });
      $newDiv.find(".ui-icon").removeClass("ui-icon ui-icon-gripsmall-diagonal-se");
      window.URL.revokeObjectURL(fileList[i]);
    }
    $(".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");
      }
    });
  }
});
