小编Bil*_*oon的帖子

当我编写客户端代码时,我使用HTML/CSS/JavaScript和最近的jQuery来加速编码,并使用改进的方法来实现相同的目标.

在我的文本编辑器中,我使用zen-coding来加速代码编写,并避免错误.我暂时将zen-coding视为一个jQuery插件,但它有一个致命的缺陷,你希望在任何javascript开始之前编写HTML并将其发送到客户端.

虽然我们可以使用JavaScript服务器(env.js或node.js),因此使用JavaScript和jQuery做了很多开发服务器端,但我不喜欢移动它,因为它是一种新兴技术,并且有很多不同和缺点(还有一些主要优点).

我想继续使用PHP服务器端,但以我最熟悉的方式开发,熟悉哪个是客户端JavaScript.

因此 - 我一直在研究QueryPath,这是一个jQuery的PHP端口,旨在获取jQuery的最佳和最相关的部分,并重新设计它以适应服务器环境.

这一切都很棒,我现在一直在研究两个能够解析zen编码的PHP类,它们在组合时可以作为一个很好的模板引擎,也可以避免代码中的错误.

我遇到的问题是zen编码解析器都不支持任何接近完整的zen编码功能集.

所以最后我的问题(抱歉相当冗长的介绍)

1. 我可以在我的PHP代码中使用更好的服务器端zen编码解析器吗？
2. 是否有一个好的(非常简洁和全功能)替代模板系统使用禅编码？(我知道这不是最初为此任务设计的)
3. 有没有更好的方法来实现我的最终目标,即缩小我编码客户端和服务器端的方式之间的界限？
4. 是否有一个PHP库实现了大量的实用程序函数,通过使用它将增强我的代码的安全性/性能,而无需我学习所有内部工作？(就像jQuery为javascript做的那样)

注意:我正在寻找功能等同而不是句法相似性 - 尽管两者对我来说都是一个加分.

这是一些注释的测试代码,应该阐明我想要实现的目标:

<?php

    // first php based zen-coding parser
    // http://code.google.com/p/zen-php
    require_once 'ZenPHP/ZenPHP.php';
    // my own wrapper function
    function zp($abbr){ return ZenPHP::expand($abbr); }

    // second php based zen-coding parser
    // https://github.com/philipwalton/PW_Zen_Coder
    require_once 'PW_Zen_Coder/PW_Zen_Coder.php';
    $zc = new PW_Zen_Coder;
    // my own wrapper function
    function pwzc($abbr){ global $zc; return $zc->expand($abbr); }

    // php port of jQuery with a new server-side flavor
    // http://querypath.org/
    require_once 'QueryPath/QueryPath.php';

    // …

有没有办法在html()被触发后启动一个事件？如:

$.post("ajax.php", {data :data}, function(data){
   $("#countries").html(data, function(){
      alert("test");
   });
});

这不起作用.

编辑:我问这个是因为我想做一些事情(另一个电话)来自呼叫的信息...我想简化示例...我想程序员总是想知道为什么...

所以这里是更新的例子

 $.post("ajax.php", {data :data}, function(data){
   $("#countries").html(data, function(){
        var id = $("#countries option:selected").attr("id");
        getRegions(id);
   });
});

是否有加密的javascript实现,包括合理的否定？

我想要展示这里描述的功能的东西:http://en.wikipedia.org/wiki/Deniable_encryption

可拒绝加密允许加密邮件的发件人拒绝发送该邮件.这需要值得信赖的第三方.可能的情况如下:

1. 爱丽丝是鲍勃的妻子,他怀疑他的妻子正在通奸.她想和她的秘密情人卡尔沟通.她创造了两把钥匙,一把打算保密,另一把打算牺牲.她将秘密密钥(或两者)传递给卡尔.
2. 爱丽丝构建了卡尔无害消息M1(打算透露给鲍勃在发现的情况下)和罪证情书M2卡尔.她从消息M1,M2中构造了密文C并将其通过电子邮件发送给Carl.
3. Carl使用他的密钥解密M2(也可能是M1,以便读取假邮件).
4. 鲍勃发现有关给卡尔的电子邮件,变得可疑并强迫爱丽丝解密邮件.
5. Alice使用牺牲密钥并向Bob显示无害消息M1.由于Bob不知道另一个密钥,他必须假设没有其他消息M2.

如何格式化ISO格式的javascript日期,但在当地时间？

与myDate.toISOString()我收到时间:"2012-09-13T19:12:23.826Z"

但是在这里,它是22:13,那么我如何在上面的格式中包含时区？

我最后做了......

pad=function(e,t,n){n=n||"0",t=t||2;while((""+e).length<t)e=n+e;return e}
c = new Date()
c.getFullYear()+"-"+pad(c.getMonth()+1)+"-"+pad(c.getDate()-5)+"T"+c.toLocaleTimeString().replace(/\D/g,':')+"."+pad(c.getMilliseconds(),3)

我正在尝试确定比特币区块链中的交易是否已经确认.我使用此url从blockchain.info访问了该事务的JSON表示:https://blockchain.info/tx/62f9419e56ac1b628840aaf52307867f9856d7a52b3c1d945a9938a3021cbf2c?show_adv = false&format = json

我在响应中找不到任何表明它有多少确认的内容......

我正在运行量角器来测试angularjs app.一切正常,但是当生成浏览器窗口时,它在后台,所以我必须使用cmd-tab来查找它,并且错过了开始时发生的事情.

有没有什么办法可以编程方式将浏览器窗口带到前台？

我正在寻找一个javascript库来转换带有移动符号的PGN文件,包括片段和目的地,如:

... 3. cxd5 Qxd5 ...

仅使用方形坐标编写符号,例如:

... 3. c4-d5 h5-d5 ...

如果没有图书馆,那么使这块岩石坚固起来将是一项相当大的工作,因为它必须逐步完成每一步,并验证合法的移动以确定哪一块可以到达目的地广场.

有什么javascript可以帮助我,或者我可以轻松移植的另一种语言？

我扩展了jQuery对象以返回它的内部HTML ...

$.fn.toString = function() {
  return this.html();
};

console.log("The inner HTML is: " + $("<div>Here, <i>there</i>, everywhere</div>"));

有什么理由说这不是默认行为吗？这会破坏什么吗？

更新以回复答案/评论

首先,除了依赖于将jQuery对象强制转换为字符串以及匹配该字符串中的文本的类型检查之外,我看不出它会如何破坏.我错了吗？

这将返回outerHTML集合中连接的所有元素.这对任何人都有意义吗？对我而言,它有点意义.

var li, list;

$.fn.toString = function() {
  var out;
  out = [];
  $.each(this, function(k, v) {
    return out.push($(v)[0].outerHTML);
  });
  return out.join("\n");
};

list = $("<ul>\n  <li>some <a href='/'>link</a> items</li>\n  <li>some <a href='/'>link</a> items</li>\n  <li>some <a href='/'>link</a> items</li>\n  <li>some <a href='/'>link</a> items</li>\n  <li>some <a href='/'>link</a> items</li>\n</ul>");

li = $("li", list);

console.log("The html of it..: " + li);

我试图在这样的玉石线中间使用mixin ......

p some paragraph text !{ 'this'+'works' } but !{ +myMixin() } breaks it!

但它不起作用.我无法弄清楚如何在一行玉的中间引用mixin.可能吗？

我正在尝试验证日期输入,所以如果它是正确的,我处理一种方式,如果无效,我处理另一种...

var date, datestring, e;

datestring = "2012-03-222";

try {
  date = new Date(datestring);
  /* Ends up logging `Invalid Date`
  */

  console.log(date);
} catch (_error) {
  e = _error;
  /* Should come here and log `Error: Invalid Date` or the likes
  */

  console.log("Erorr: " + e);
}

我可以检查返回的字符串,看看它是否Invalid Date存在,但是我很惊讶这try/catch对于这种情况不起作用,并担心可能有其他错误消息我不匹配.

我该如何处理这个问题？
