隐藏绝对定位的div溢出会破坏Javascript [英] Hiding overflow of absolutely positioned div disrupts Javascript

问题描述

我在解决方案方面获得了一些帮助，使该箭头"在单击时与上方对象的中间对齐...正在起作用.

I got some help with a solution to make this "arrow" align with the middle of the objects above it on click...it was working.

从那时起，我在设计上做了更多工作，需要将"wrap" div的溢出设置为position:relative以隐藏箭头的x轴溢出...有效，但是:

Since then, I have done some more work on the design and needed to set the overflow of the "wrap" div to position:relative in order to hide x-axis overflow of the arrow...that works, but:

现在对齐已结束.我不知道为什么原因，因为我对jQuery不好:(

Now the alignment has gone off. I can't figure out why as I am no good with jQuery :(

一个重要的注意事项:该网站具有响应能力，并且现在调整浏览器的宽度正在使箭头位置发疯(仅因为我已将自动换行设置为position:relative).

One important note: this site is responsive, and adjusting the browser width is now doing crazy stuff to the arrow position (only since I've changed the wrap to position:relative).

感谢您的帮助！

HTML:

<div class="container">                        
        <div class="row">

                <ol class="flexslider-nav">
                    <li class="threecol">

            <div class="row">

                <div class="twelvecol last">

                     <div class="arrow-wrap">

                </div><!--end col-->

            </div><!--end row-->

CSS:

   .container p {
       color: #fff;
       line-height: 100px;
       background: #000;
       text-align: center;
       margin: 20px 0 0 0;
    }

    .flexslider p {
        margin-top:0px;
        background:transparent;
        color:#000000;
    }

    .flexslider {
        border-bottom:1px #000 solid;
        border-left:1px #000 solid;
        border-right:1px #000 solid;
    }

    h1, h2, h3 {
        text-align:center;
    }

    .flexslider-nav li img {
        display:block;
        margin:0px auto;
    }

    .arrow {
      position:absolute;
      background:transparent url(http://nillabean.com/images/arrow.png) repeat-x bottom center;
      width:2200px;
      height:40px;
    }

    .arrow-wrap {
        position:relative;       
        height:35px;
        border:1px #C00 solid;
    }

​

JQUERY:

        var start_pos = $("#discover").offset().left + $("#discover").width()/2 - $(".arrow").width()/2;

    $(".arrow").css("left", start_pos);

    $(".btn-workflow").click(function(event){
        var x = $(this).offset().left;

        var img_width = $(this).width();
        var arrow_width = $(".arrow").width();

        var arrow_x = x + img_width/2 - arrow_width/2;

        $(".arrow").animate({
            "left": arrow_x
        }, "slow");
    });  

图像:

这最终是我要尝试的工作...边框和透明度使此操作变得比仅添加简单箭头还要困难.

This is ultimately what I'm trying to do...the border and transparency are making this more difficult than just adding s simple arrow.

推荐答案

http://jsfiddle.net/y86RG/13/ 那行得通吗?这就是我所做的改变

http://jsfiddle.net/y86RG/13/ Will that work? Here's what I have changed

.arrow {
  position:absolute;
  background:transparent url(http://nillabean.com/images/arrow.png) repeat-x bottom center;
  left: 0;
  top: 0;
  right: 0;
  height:35px;
}

.arrow-wrap {
    position:relative;       
    height:35px;
    border:1px #C00 solid;
}

然后在JS中，删除以下行

And in the JS, removed the following line

//        $(".arrow").css("left", start_pos);
