我正在实施扩展程序以记录所有浏览器操作
$(document).on()正在少数几个网站上工作，$("a").on()正在少数网站上工作。所以我把它们放在dom.js的单个文件中。截至目前，它正在录制两个动作。如何处理只记录一个动作？
请帮帮我。
var bindEventToNewElement = function(e) {
var target = $(e.target.tagName);
$(target).off().on('click',function (e) {
alert("target");
if (e.target !== this) return;
// e.stopPropagation();
var content="";
if($(this).text()!==undefined){
content=$(this).text();
}
if(($(this).attr('href')=="")||($(this).attr('href')=="#")||($(this).attr('href')==null)) {
sendmsg(getPath(this), "click",'',content,"link",traverseElement(this),window.location.href,getElementName(this));
}else{
sendmsg($(this).attr('href'), "redirect", '',content,"link",traverseElement(this),window.location.href,getElementName(this));
}
$(target).off();
$(document).off('click','a');
$(document).on('click','a');
$("a").on('click');
});
};
/**
* DOMNodeInserted event for adding dynamic html content
*/
$(document).on('DOMNodeInserted','a',bindEventToNewElement);
/*
* Event of clicking on anchor tag and attaching event to root level document
*/
$(document).on('click','a', function(obj) {
if (obj.target !== this) return;
// obj.stopPropagation();
var content="";
if($(this).text()!==undefined){
content=$(this).text();
}
if(($(this).attr('href')=="")||($(this).attr('href')=="#")||($(this).attr('href')==null)) {
sendmsg(getPath(this), "click",'',content,"link",traverseElement(this),window.location.href,getElementName(this));
}else{
sendmsg($(this).attr('href'), "redirect", '',content,"link",traverseElement(this),window.location.href,getElementName(this));
}
});
/*
* Event of clicking on anchor tag and attaching event handler directly to the DOM
*/
$("a").on('click',function(obj) {
if (obj.target !== this) return;
var content="";
if($(this).text()!==undefined){
content=$(this).text();
}
if(($(this).attr('href')=="")||($(this).attr('href')=="#")||($(this).attr('href')==null)) {
sendmsg(getPath(this), "click",'',content,"link",traverseElement(this),window.location.href,getElementName(this));
}else{
sendmsg($(this).attr('href'), "redirect", '',content,"link",traverseElement(this),window.location.href,getElementName(this));
}
$(document).off('click','a');
