如何停止可拖动元素Jquery Ui的大小调整？

Question

I have a working area ,where I can drag&drop and resize my element.

$(objName).draggable({
    start: function (ev, ui) {$(this).css({opacity:0.3})},

    cursor:'move',
    containment: 'parent',
    snap:true,
    stop: function (ev, ui) {
        $(this).css({opacity:1});
        var pos = $(ui.helper).offset();
        console.log($(this).attr("id"));
        console.log(pos.left)
        console.log(pos.top)
    }
})
.resizable({ghost:true,

});

But if I start resizing it ,the size can't be fixed by the borders of working area.

What you need to do is confine the Element on the resize as well as the Draggable to the working area like so

$(objName).draggable({
    start: function (ev, ui) {$(this).css({opacity:0.3})},

    cursor:'move',
    snap:true,
    drag: function(e, ui){
        var topRightCornerPos_x = $(this).css('left') + $(this).width();
        var bottomLeftConerPos_y = $(this).css('top') + $(this).width();

        if(topRightCornerPos_x > $(this).parent().width()){
            var maxLeft = $(this).parent().width() - $(this).width();
            $(this).css('left', maxLeft);
        }
        if(bottomLeftConerPos_y  > $(this).parent().height()){
            var maxTop = $(this).parent().height() - $9this).height();
            $(this).css('top', maxTop);
        }
    },
    stop: function (ev, ui) {
        $(this).css({opacity:1});
        var pos = $(ui.helper).offset();
        console.log($(this).attr("id"));
        console.log(pos.left)
        console.log(pos.top)
    }
})
.resizable({ghost:true,
    containment: $('#workingarea_id')
});

or again you can use containment: 'parent' in the resizable params
