javascript 获取当前位置的文本

Question

如何获取鼠标所在位置的文本？ 我现在有一些这样的

document.body.onmousemove = function(){
    //todo:Get text at mouse position
}

Answer 1

One way of doing so is using [PrototypeJs][1]

Try this one let me know if there is any problem

$(document.body).observe('click', respondToClick);

function respondToClick(event) {
  var element = event.element();
  var source = element.innerHTML;
}
