问题描述
如何拦截文档中的链接点击?它必须是跨平台的。
我正在寻找这样的东西:
<$ p $内容是innerHTML的div
var content = document.getElementById(ControlPanelContent);
content.addEventListener(click,ContentClick,false);
函数ContentClick(event){
if(event.href ==http:// oldurl)
{
event.href =的 http:// NEWURL;
$ b
感谢您的帮助。 b $ b
解决方案
for(var ls = document.links,numLinks = ls.length,i = 0; i< numLinks; i ++){
ls [i] .href =...酷刑小狗在这里...;
code
$ b 或者,如果你只是想拦截,而不是改变,添加一个onclick处理程序。这会在导航到url之前被调用:
var handler = function(){
...折磨小猫这里...
for(var ls = document.links,numLinks = ls.length,i = 0; i< numLinks; i ++){
ls [i] .onclick =处理程序;
$ / code>
请注意 document.links
还包含具有 href
属性的 AREA
元素 - 而不仅仅是 A
元素。
how do I intercept link clicks in document?it must be cross-platform.
I am looking for something like this:
// content is a div with innerHTML
var content = document.getElementById("ControlPanelContent");
content.addEventListener("click", ContentClick, false);
function ContentClick(event) {
if(event.href == "http://oldurl")
{
event.href = "http://newurl";
}
}
Thanks in advance for help.
解决方案 for (var ls = document.links, numLinks = ls.length, i=0; i<numLinks; i++){
ls[i].href= "...torture puppies here...";
}
alternatively if you just want to intercept, not change, add an onclick handler. This will get called before navigating to the url:
var handler = function(){
...torment kittens here...
}
for (var ls = document.links, numLinks = ls.length, i=0; i<numLinks; i++){
ls[i].onclick= handler;
}
Note that document.links
also contains AREA
elements with a href
attribute - not just A
elements.
