javascript在mose postion獲取文本

Question

如何在鼠標位置獲取文本？ 我現在已經有些喜歡這個

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; 
}
