js代碼，鼠標(biāo)在頁(yè)面點(diǎn)擊時(shí)，記錄元素的Xpath
代碼：
function mouse_down(event){
var x = event.clientX, y = event.clientY
var element = document.elementFromPoint(x, y)
if (!element) {
console.log("error: no element")
}
console.log(readXPath(element))
}
function readXPath(element) {
count = 1
result = ""
while (true){
count += 1
if(count>99){
break
}
if (element == document.body){
console.log('/html/body/' + result)
break
}
else
{
tag_index = 0
tmp = element.parentElement
for(var i=0;i<tmp.childElementCount;i++){
if (tmp.children[i].tagName == element.tagName){
tag_index += 1
}
if (element == tmp.children[i]){
result = element.tagName.toLowerCase() + "[" + String(tag_index) + "]" + "/" +result
// console.log(result)
break
}
}
element = tmp
}
}
}
document.onmousedown = mouse_down
