jQuery UI可调整大小也可以反向调整

Question

如何使jQuery UI Resizable也可以反向调整.

假设在html中有两个div标签,如果我向上调整意味着另一个东西必须向下调整大小

<script>
        $(function() {
        $("#resizable").resizable({alsoResize: ".myiframe"});

    });
</script>
<div id = "resizable">
        This is the resizable content...
</div>

<div class="myframe">
   This must resize in reverse direction...
</div>

我尝试了但没有用,请指导解决这个问题

Answer 1

通过修改jQuery用于实现alsoResize选项的代码,我们可以自己做出alsoResizeReverse选择.然后我们可以简单地使用如下:

$("#resizable").resizable({
    alsoResizeReverse: ".myframe"
});

原始alsoResize选项的结构已经在各种版本的jQuery UI上进行了更改,我的原始代码在较新版本中不起作用.我将在1.8.1和1.11.4版本中提供添加此功能的代码.

只有几件事情必须改变,如明显的重命名alsoResize,以alsoResizeReverse和减去delta加入它(是什么让逆转调整大小)来代替.原始alsoResize代码从jQuery UI 版本1.8.1的第2200 行和版本1.11.4的第7922行开始.您可以在此处看到所需的一些更改.

要添加alsoResizeReverse功能,请将其添加到您的javascript(这应该放在document.ready()之外):

对于较新版本的jQuery UI(示例基于v1.11.4):

$.ui.plugin.add("resizable", "alsoResizeReverse", {

    start: function() {
        var that = $(this).resizable( "instance" ),
            o = that.options;

        $(o.alsoResizeReverse).each(function() {
            var el = $(this);
            el.data("ui-resizable-alsoresizeReverse", {
                width: parseInt(el.width(), 10), height: parseInt(el.height(), 10),
                left: parseInt(el.css("left"), 10), top: parseInt(el.css("top"), 10)
            });
        });
    },

    resize: function(event, ui) {
        var that = $(this).resizable( "instance" ),
            o = that.options,
            os = that.originalSize,
            op = that.originalPosition,
            delta = {
                height: (that.size.height - os.height) || 0,
                width: (that.size.width - os.width) || 0,
                top: (that.position.top - op.top) || 0,
                left: (that.position.left - op.left) || 0
            };

        $(o.alsoResizeReverse).each(function() {
            var el = $(this), start = $(this).data("ui-resizable-alsoresize-reverse"), style = {},
                css = el.parents(ui.originalElement[0]).length ?
                    [ "width", "height" ] :
                    [ "width", "height", "top", "left" ];

            $.each(css, function(i, prop) {
                var sum = (start[prop] || 0) - (delta[prop] || 0);
                if (sum && sum >= 0) {
                    style[prop] = sum || null;
                }
            });

            el.css(style);
        });
    },

    stop: function() {
        $(this).removeData("resizable-alsoresize-reverse");
    }
});

对于旧版本(基于v1.8.1 - 我的原始答案):

$.ui.plugin.add("resizable", "alsoResizeReverse", {

    start: function(event, ui) {

        var self = $(this).data("resizable"), o = self.options;

        var _store = function(exp) {
            $(exp).each(function() {
                $(this).data("resizable-alsoresize-reverse", {
                    width: parseInt($(this).width(), 10), height: parseInt($(this).height(), 10),
                    left: parseInt($(this).css('left'), 10), top: parseInt($(this).css('top'), 10)
                });
            });
        };

        if (typeof(o.alsoResizeReverse) == 'object' && !o.alsoResizeReverse.parentNode) {
            if (o.alsoResizeReverse.length) { o.alsoResize = o.alsoResizeReverse[0];    _store(o.alsoResizeReverse); }
            else { $.each(o.alsoResizeReverse, function(exp, c) { _store(exp); }); }
        }else{
            _store(o.alsoResizeReverse);
        }
    },

    resize: function(event, ui){
        var self = $(this).data("resizable"), o = self.options, os = self.originalSize, op = self.originalPosition;

        var delta = {
            height: (self.size.height - os.height) || 0, width: (self.size.width - os.width) || 0,
            top: (self.position.top - op.top) || 0, left: (self.position.left - op.left) || 0
        },

        _alsoResizeReverse = function(exp, c) {
            $(exp).each(function() {
                var el = $(this), start = $(this).data("resizable-alsoresize-reverse"), style = {}, css = c && c.length ? c : ['width', 'height', 'top', 'left'];

                $.each(css || ['width', 'height', 'top', 'left'], function(i, prop) {
                    var sum = (start[prop]||0) - (delta[prop]||0); // subtracting instead of adding
                    if (sum && sum >= 0)
                        style[prop] = sum || null;
                });

                //Opera fixing relative position
                if (/relative/.test(el.css('position')) && $.browser.opera) {
                    self._revertToRelativePosition = true;
                    el.css({ position: 'absolute', top: 'auto', left: 'auto' });
                }

                el.css(style);
            });
        };

        if (typeof(o.alsoResizeReverse) == 'object' && !o.alsoResizeReverse.nodeType) {
            $.each(o.alsoResizeReverse, function(exp, c) { _alsoResizeReverse(exp, c); });
        }else{
            _alsoResizeReverse(o.alsoResizeReverse);
        }
    },

    stop: function(event, ui){
        var self = $(this).data("resizable");

        //Opera fixing relative position
        if (self._revertToRelativePosition && $.browser.opera) {
            self._revertToRelativePosition = false;
            el.css({ position: 'relative' });
        }

        $(this).removeData("resizable-alsoresize-reverse");
    }
});

我有一个问题,让"Simen Echholt"代码与jQuery 1.9.1/jquery-ui(1.10.2)一起工作,但是当我用" $(this).data(" resizable ") "with" $(this).data(" ui-resizable ") ".

Answer 3

更新到jQuery 2.1.1和jQuery UI 1.11.2.

$.ui.plugin.add("resizable", "alsoResizeReverse", {

  start: function() {
    var that = $(this).resizable("instance"),
      o = that.options,
      _store = function(exp) {

            width: parseInt(el.width(), 10),
            height: parseInt(el.height(), 10),
            left: parseInt(el.css("left"), 10),
            top: parseInt(el.css("top"), 10)
          });
        });
      };

    if (typeof(o.alsoResizeReverse) === "object" && !o.alsoResizeReverse.parentNode) {
      if (o.alsoResizeReverse.length) {
        o.alsoResizeReverse = o.alsoResizeReverse[0];
        _store(o.alsoResizeReverse);
      } else {
        $.each(o.alsoResizeReverse, function(exp) {
          _store(exp);
        });
      }
    } else {
      _store(o.alsoResizeReverse);
    }
  },

  resize: function(event, ui) {
    var that = $(this).resizable("instance"),
      o = that.options,

        top: (that.position.top - op.top) || 0,

      _alsoResizeReverse = function(exp, c) {
        $(exp).each(function() {

          $.each(css, function(i, prop) {
            var sum = (start[prop] || 0) - (delta[prop] || 0);
            if (sum && sum >= 0) {
              style[prop] = sum || null;
            }
          });

          el.css(style);
        });
      };

    if (typeof(o.alsoResizeReverse) === "object" && !o.alsoResizeReverse.nodeType) {
      $.each(o.alsoResizeReverse, function(exp, c) {
        _alsoResizeReverse(exp, c);
      });
    } else {
      _alsoResizeReverse(o.alsoResizeReverse);

  },

  stop: function() {
    $(this).removeData("resizable-alsoResizeReverse");
  }
});
$(function() {

  $("#resizable").resizable({
    alsoResizeReverse: ".myframe"

});

#resizable,
.myframe {
  border: 1px solid black;
  padding: 10px;
  margin-bottom: 20px;
  width: 50%;
  height: 150px
