Question

当您将鼠标悬停在绿色突出显示上时，会出现一系列颜色。这将允许您更改突出显示的颜色。顺便说一句，SO编辑器正在使#change_color div的偏移量测量不正确。 如何将其设置在哪里，除非鼠标位于.green_mark或#change_color之上，#change_color隐藏了其可见性？

$(".green_mark").mouseover(function() {
    var offsets = $(this).offset();
    var top = offsets.top;
    var new_top = top - 10;
    var left = offsets.left;
    var new_left = left - 10;
    $("#change_color").css("visibility","visible");
    $('#change_color').css({
      'top':new_top+'px',
      'left':new_left+'px'
    });
 });

#change_color { 
    position:absolute;
    border:grey solid 1px;
    background: #373737;
    padding: 5px;
    border-radius: 3px;
    -webkit-touch-callout: none; /* iOS Safari */
    -webkit-user-select: none;   /* Chrome/Safari/Opera */
    -khtml-user-select: none;    /* Konqueror */
    -moz-user-select: none;      /* Firefox */
    -ms-user-select: none;       /* Internet Explorer/Edge */
    user-select: none;           /* Non-prefixed version, currently
                                 not supported by any browser */
    visibility: hidden;

Answer 1

使用mouseout事件：

$(".green_mark").mouseout(function() {
$("#change_color").css("visibility","hidden");});

如果你从绿色鼠标移动到达颜色div，它会出错，所以要确保位置错误是固定的，所以你永远不要让绿色覆盖颜色div（所以颜色div接近足够）;您可以在鼠标位置渲染颜色div来修复该部分。

Answer 2

您可以订阅mouseenter和mouseleave个活动。

var colorPickerHovered = false;
var timer;

$(".green_mark").mouseenter(function() {
        if(timer){
        clearTimeout(timer);
    }
    var offsets = $(this).offset();
    var top = offsets.top;
    var new_top = top - 10;
    var left = offsets.left;
    var new_left = left - 10;
  $("#change_color").css("visibility","visible");
    $('#change_color').css({
  'top':new_top+'px',
  'left':new_left+'px'
    });
 });

$(".green_mark").mouseleave(function(){
    timer = setTimeout(function(){
    if(!colorPickerHovered){
      $("#change_color").css("visibility","hidden");
  }
  }, 250)
})

$("#change_color").mouseenter(function(){
    colorPickerHovered = true;
})

$("#change_color").mouseleave(function(){
    colorPickerHovered = false;
  $(this).css("visibility","hidden");
})
