HTML - 来自一个div的子元素覆盖其他div

时间:2017-09-04 06:42:34

标签: javascript jquery html css

我在divs页面中连续两次HTML

首先div包含spanrelative的{​​{1}}。这就是为什么它超过了第二个div。

我有一个与两个div关联的点击事件。

当我点击第positionspan的部分时,它会触发第一个div点击事件,但我想在此处触发第二个div's点击事件

有没有办法实现这一目标。

enter image description here

div's
function div1Clicked() {
  alert('div 1 clicked');
}

function div2Clicked() {
  alert('div 2 clicked');
}
#div1 {
  border: 1px solid gainsboro;
  height: 100px;
  width: 13%;
  background: red;
  display: inline;
  float: left;
}

#div1 span {
  width: 316px;
  height: 30px;
  background: green;
  float: left;
  margin-top: 39px;
  position: relative;
}

#div2 {
  border: 1px solid gainsboro;
  height: 100px;
  width: 13%;
  background: red;
  display: inherit;
  float: left;
}

如果您不需要在子跨度上使用任何悬停状态,您可以这样做。请记住,这与你的html略有不同,但它可以很容易地转换为你的html / css,我现在没有时间去做。

你要做的是在:after更高的两个div上添加z-index,这将覆盖span并作为javascript的触发区域。不要介意我看起来很奇怪的css"它的BEM。你可以使用你的javascript触发器,它会很好用。如果您不熟悉所选浏览器中的devtools,则可以使用alert()代替console.log()

DEMO

<div class="block">
  <div class="block__column block__column--left js-action-1"></div>
  <div class="block__column block__column--right js-action-2"></div>

   <div class="block__description">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Nihil, voluptas!</div>
</div>


.block {
  display: flex;
  position: relative;
}

.block__column {
  width: 50%;
  height: 20rem;
  position: relative;
}

.block__column:after {
  content: '';
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  z-index: 2;
}

.block__column:hover {
  cursor: pointer;
}

.block__column--left {
  background-color: deepskyblue;
}

.block__column--right {
  background-color: deeppink;
}

.block__description {
  position: absolute;
  top: 50%;
  left: 2rem;
  right: 2rem;
  background-color: white;
}


$('.js-action-1').on('click', function() {
 console.log('clicked the left column');
});

$('.js-action-2').on('click', function() {
 console.log('clicked the right column');
});

<div onclick="div2Clicked()" id="div2" style="

}

function div2Clicked(){
alert('div 2 clicked');
}
</script>
</body></html>

如果触发事件父elemnet(div1)事件,则单击span元素,因此无法获得正确的输出。但是你得到输出一些检查条件。请参考下面的片段

function div1Clicked(){
if($("div:first").width() < event.offsetX)
div2Clicked()
else
alert('div 1 clicked');
}

由于跨度位于div1中,当它被点击时,它将仅触发div1 click事件,即使它与div2重叠。因此,如果您可以使用绿色范围的点击事件,它可能会有所帮助。它仍会触发div1点击事件。

    <html><head></head>
    <body>
    <div onclick="div1Clicked()" id="div1" style="
        border: 1px solid gainsboro;
        height: 100px;
        width: 13%;
        background: red;
        display: inline;
        float: left;
    ">
    <span style="
        width: 316px;
        height: 30px;
        background: green;
        float: left;
        margin-top: 39px;
        position: relative;
    " onclick="spanClicked()">
    </span>
    </div>

    <div onclick="div2Clicked()" id="div2" style="
        border: 1px solid gainsboro;
        height: 100px;
        width: 13%;
        background: red;
        display: inherit;
        float: left;
    ">

    function div1Clicked(){
    alert('div 1 clicked');
    }

    function spanClicked(){
    alert('span clicked');

    function div2Clicked(){
    alert('div 2 clicked');
    }

如果click-events上的span不是必需的,您可以将pointer-events: none应用于该范围,该范围将完全忽略该范围内的点击次数。

&#13;
function div1Clicked() {
  alert('div 1 clicked');
}

function div2Clicked() {
  alert('div 2 clicked');
}
&#13;
#div1 {
  border: 1px solid gainsboro;
  height: 100px;
  width: 13%;
  background: red;
  display: inline;
  float: left;
}

#div1 span {
  width: 316px;
  height: 30px;
  background: green;
  float: left;
  margin-top: 39px;
  position: relative;
  pointer-events: none;  /*This will make the span click-through*/
}

#div2 {
  border: 1px solid gainsboro;
  height: 100px;
  width: 13%;
  background: red;
  display: inherit;
  float: left;
}
&#13;
<body>
  <div onclick="div1Clicked()" id="div1">
    <span></span>

  <div onclick="div2Clicked()" id="div2">

您可以执行以下代码段...

$('.first,.second').click(function(){
	alert($(this).attr('class'))
})
.first{
    width:200px;
    height:300px;
    background-color:red;
    display:inline-block;
    float:left;
    position:relative;
}
span{
