我有一个网页,其中将单击事件绑定到元素上。用户单击特定元素时。我想从html或body标签开始生成元素的XPath。即“绝对Xpath”
假设在下面的html示例中,我单击跨度为“ USA”的文本,因此绝对Xpath 为
/html[1]/body[1]/div[2]/div[1]/div[1]/span[1]
<html>
<body>
<div class="header">Countries</div>
<div class="row">
<div class="row_in">
<div class="row_in_in">
<span>India</span>
</div>
</div>
</div>
<div class="row">
<div class="row_in">
<div class="row_in_in">
<span>USA</span>
</div>
</div>
</div>
<div class="row">
<div class="row_in">
<div class="row_in_in">
<span>UK</span>
</div>
</div>
</div>
<div class="row">
<div class="row_in">
<div class="row_in_in">
<span>France</span>
</div>
</div>
</div>
</body>
</html>
我们是否有任何库可在其中帮助我生成XPath并将元素Dom传递给XPath?
我遇到了几个库,但是这些库基于提供的Xpath帮助检测html内的内容。
答案 0 :(得分:1)
您需要遍历clicked元素及其父元素来完成此工作。因此,您可以调用函数嵌套来完成这项工作。
var xpath;
$("*").click(function(e){
xpath = '';
addXpath($(this));
console.log(xpath);
e.stopPropagation();
});
function addXpath($ele){
var tagName = $ele[0].tagName.toLowerCase();
var index = $ele.parent().children(tagName).index($ele)+1;
xpath = '/'+tagName +'['+index+']'+ xpath;
!$ele.parent().is(document) ? addXpath($ele.parent()) : "";
}
