基于innerHTML中的script广告实现代码[广告全部放在一个js里面][原创]_广告代码

 如果不清楚innerHtml的脚本如何运行的可以参考这篇文章
http://www.gxlcms.com/article/234.htm
下面的代码目的就是防止有些网站需要将一些特别的广告放到script中，大家可以完全用iframe替换，联盟广告大家可以用后加载的方式，特别处理。
推荐的代码的写法：
代码如下:
if(PageClass==2)
{
//顶部通栏 468*60用iframe方式加载
set_innerHTML('Head_2_2',All_Top_468_60);
//顶部468*60
set_innerHTML('Head_5',All_Top_970_60);
Temp_Adv='src="https://www.gxlcms.com/show/html/List_1_1_4.html" style="margin-bottom:5px;">';
set_innerHTML('List_1_1_4',Temp_Adv);

//下载右边文字 直接地址+图片 推荐
Temp_Adv='| 脚本之家 ';
document.getElementById("Soft_1_2_4_h2").innerHTML+=Temp_Adv;
// set_innerHTML('Soft_1_2_2_1_2',Temp_Adv);
}

上面的是4668*60 上面的是4668*602 因为直接用的是inner所有不显示。 var PageClass=1 //上面主要是为了区分页面，首页，列表页，内容页的控制，原理不错 var global_html_pool = []; var global_script_pool = []; var global_script_src_pool = []; var global_lock_pool = []; var innerhtml_lock = null; var document_buffer = ""; function set_innerHTML(obj_id, html, time) { if (innerhtml_lock == null) { innerhtml_lock = obj_id; } else if (typeof(time) == "undefined") { global_lock_pool[obj_id + "_html"] = html; window.setTimeout("set_innerHTML('" + obj_id + "', global_lock_pool['" + obj_id + "_html']);", 20); return; } else if (innerhtml_lock != obj_id) { global_lock_pool[obj_id + "_html"] = html; window.setTimeout("set_innerHTML('" + obj_id + "', global_lock_pool['" + obj_id + "_html'], " + time + ");", 20); return; } function get_script_id() { return "script_" + (new Date()).getTime().toString(36) + Math.floor(Math.random() * 100000000).toString(36); } document_buffer = ""; document.write = function (str) { document_buffer += str; } document.writeln = function (str) { document_buffer += str + "\n"; } global_html_pool = []; var scripts = []; html = html.split(/<\/script>/i); for (var i = 0; i < html.length; i++) { global_html_pool[i] = html[i].replace(/') + 1); scripts[i].src = scripts[i].src.match(/src\s*=\s*(\"([^\"]*)\"|\'([^\']*)\'|([^\s]*)[\s>])/i); if (scripts[i].src) { if (scripts[i].src[2]) { scripts[i].src = scripts[i].src[2]; } else if (scripts[i].src[3]) { scripts[i].src = scripts[i].src[3]; } else if (scripts[i].src[4]) { scripts[i].src = scripts[i].src[4]; } else { scripts[i].src = ""; } scripts[i].text = ""; } else { scripts[i].src = ""; scripts[i].text = scripts[i].text.substr(scripts[i].text.indexOf('>') + 1); scripts[i].text = scripts[i].text.replace(/^\s*<\!--\s*/g, ""); } } var s; if (typeof(time) == "undefined") { s = 0; } else { s = time; } var script, add_script, remove_script; for (var i = 0; i < scripts.length; i++) { var add_html = "document_buffer += global_html_pool[" + i + "];\n"; add_html += "document.getElementById('" + obj_id + "').innerHTML = document_buffer;\n"; script = document.createElement("script"); if (scripts[i].src) { script.src = scripts[i].src; if (typeof(global_script_src_pool[script.src]) == "undefined") { global_script_src_pool[script.src] = true; s += 2000; } else { s += 10; } } else { script.text = scripts[i].text; s += 10; } script.defer = true; script.type = "text/javascript"; script.id = get_script_id(); global_script_pool[script.id] = script; add_script = add_html; add_script += "document.getElementsByTagName('head').item(0)"; add_script += ".appendChild(global_script_pool['" + script.id + "']);\n"; window.setTimeout(add_script, s); remove_script = "document.getElementsByTagName('head').item(0)"; remove_script += ".removeChild(document.getElementById('" + script.id + "'));\n"; remove_script += "delete global_script_pool['" + script.id + "'];\n"; window.setTimeout(remove_script, s + 10000); } var end_script = "if (document_buffer.match(/<\\/script>/i)) {\n"; end_script += "set_innerHTML('" + obj_id + "', document_buffer, " + s + ");\n";

[Ctrl+A 全选 注:如需引入外部Js需刷新才能执行]
经测试发现，如果想在有运行script的上面加广告是不可能的因为这些脚本是后执行的，所有脚本广告可以直接在脚本中写入，不要随便的后加入了。

但如果是其它的广告是可以前面加入广告的，一些网站都是直接通过script控制全站的广告，虽然脚本之家暂时没有使用这种方法，不过在以后我们也会参考这个方法。

最主要的是广告，大家可以尽量的避免使用script,尽量的使用iframe或直接代码，图片链接等方法是非常不错的。
