可调整大小的左右箭头

Question

我正在尝试向左侧和右侧添加2个圆圈到可调整大小的div并设置它们的样式。我添加它们似乎没问题，但是当我尝试调整右侧左侧时，圆圈在同一位置保持不变。想法是用可调整大小的div移动圆圈。你能帮我吗？

$("#resizable").resizable({
  containment: "#image-container-step2",
  handles: "e,w"
});

#resizable {
  background: red;
  position: absolute;
  height: 10px;
  width: 200px;
  top: 100px;
  /*left: 100px;*/
}

#resizable .resizers {
  width: 100%;
  height: 100%;
  border: 3px solid #4286f4;
  box-sizing: border-box;
}

#resizable .resizers .resizer {
  width: 25px;
  height: 25px;
  border-radius: 50%;
  background: white;
  border: 3px solid #4286f4;
  position: absolute;
}

#resizable .resizers .resizer.left {
  left: -5px;
  top: -7px;
  cursor: w-resize;
  /*resizer cursor*/
}

#resizable .resizers .resizer.right {
  left: 190px;
  top: -7px;
  cursor: e-resize;
  /*resizer cursor*/
}

<div id="resizable">

    <div class="resizer right"></div>
  </div>
</div>

Answer 1

而不是给.resizer.right left: 190px只是给它right: -5px。现在，如果您调整大小，它将与该行。希望能帮助到你

代码已更新，现在它也可以通过圆圈重新调整大小

$("#resizable").resizable({
  containment: "#resizable",
  handles: "e,w"
});

#resizable {
  background: red;
  position: absolute;
  height: 10px;
  width: 200px;
  top: 100px;
  /*left: 100px;*/
}

#resizable .resizers {
  width: 100%;
  height: 100%;
  border: 3px solid #4286f4;
  box-sizing: border-box;
}

#resizable .resizers .resizer {
  width: 25px;
  height: 25px;
  border-radius: 50%;
  background: white;
  border: 3px solid #4286f4;
  position: absolute;
}
#resizable .ui-resizable-handle{
    width: 31px;
    height: 31px;
    top: 50%;
    transform: translateY(-50%);
}
#resizable .resizers .resizer.left,#resizable .resizers .resizer.right{
top:50%;
transform:translateY(-50%);
}
#resizable .resizers .resizer.left {
  left: -5px;
  cursor: w-resize;
  /*resizer cursor*/
}

#resizable .resizers .resizer.right {
  right: -5px;
  cursor: e-resize;
  /*resizer cursor*/
}
