小编sco*_*ohh的帖子

我想验证文件名

文件或文件夹的名称不应包含\ /？%*:| "<>.

你能建议我在preg_match()中使用正则表达式吗？

谢谢.

我有一个来自可视网站优化器的javascript代码,它将放在HTML标题上:

var _vwo_code=(function(){
var account_id=7237,
settings_tolerance=2000,
library_tolerance=1500,
use_existing_jquery=true,
// DO NOT EDIT BELOW THIS LINE
f=false,d=document;return{use_existing_jquery:function(){return use_existing_jquery;},library_tolerance:function(){return library_tolerance;},finish:function(){if(!f){f=true;var a=d.getElementById('_vis_opt_path_hides');if(a)a.parentNode.removeChild(a);}},finished:function(){return f;},load:function(a){var b=d.createElement('script');b.src=a;b.type='text/javascript';b.innerText;b.onerror=function(){_vwo_code.finish();};d.getElementsByTagName('head')[0].appendChild(b);},init:function(){settings_timer=setTimeout('_vwo_code.finish()',settings_tolerance);this.load('//dev.visualwebsiteoptimizer.com/j.php?a='+account_id+'&u='+encodeURIComponent(d.URL)+'&r='+Math.random());var a=d.createElement('style'),b='body{opacity:0 !important;filter:alpha(opacity=0) !important;background:none !important;}',h=d.getElementsByTagName('head')[0];a.setAttribute('id','_vis_opt_path_hides');a.setAttribute('type','text/css');if(a.styleSheet)a.styleSheet.cssText=b;else a.appendChild(d.createTextNode(b));h.appendChild(a);return settings_timer;}};}());_vwo_settings_timer=_vwo_code.init();

但我想只在这种情况下运行此代码:

$(document).ready(function(){
  if($('#selectedLang').val() == 'en_US')
  {
    //run the visual website optimizer code
  }
});

我试过这个,但返回错误"_vwo_code未定义"

$(document).ready(function(){
  if($('#selectedLang').val() == 'en_US')
  {
    var _vwo_code=(function(){
    var account_id=7237,
    settings_tolerance=2000,
    library_tolerance=1500,
    use_existing_jquery=true,
    // DO NOT EDIT BELOW THIS LINE
    f=false,d=document;return{use_existing_jquery:function(){return use_existing_jquery;},library_tolerance:function(){return library_tolerance;},finish:function(){if(!f){f=true;var a=d.getElementById('_vis_opt_path_hides');if(a)a.parentNode.removeChild(a);}},finished:function(){return f;},load:function(a){var b=d.createElement('script');b.src=a;b.type='text/javascript';b.innerText;b.onerror=function(){_vwo_code.finish();};d.getElementsByTagName('head')[0].appendChild(b);},init:function(){settings_timer=setTimeout('_vwo_code.finish()',settings_tolerance);this.load('//dev.visualwebsiteoptimizer.com/j.php?a='+account_id+'&u='+encodeURIComponent(d.URL)+'&r='+Math.random());var a=d.createElement('style'),b='body{opacity:0 !important;filter:alpha(opacity=0) !important;background:none !important;}',h=d.getElementsByTagName('head')[0];a.setAttribute('id','_vis_opt_path_hides');a.setAttribute('type','text/css');if(a.styleSheet)a.styleSheet.cssText=b;else a.appendChild(d.createTextNode(b));h.appendChild(a);return settings_timer;}};}());_vwo_settings_timer=_vwo_code.init();
  }
});

请帮我解决这个问题？提前致谢!

我想计算具有类名"items"并具有属性"style = display:none"的div.

<div id="skills">
<div class="items" style="display:none">1</div>
<div class="items">2</div>
<div class="items">3</div>
<div class="items" style="display:none">4</div>
<div class="items" style="display:none">5</div></div>

输出应该是'3'.

================================================== =========

除了问题:

<div id="skills1">
<div class="items" style="display:none">1</div>
<div class="items">2</div>
<div class="items">3</div>
<div class="items" style="display:none">4</div>
<div class="items" style="display:none">5</div></div>

<div id="skills2">
<div class="items" style="display:none">1</div>
<div class="items" style="display:none">2</div>
<div class="items" style="display:none">3</div>
<div class="items" style="display:none">4</div>
<div class="items" style="display:none">5</div></div>

输出应该是'3'和'5'.

这是我的代码(从第35行开始):

location /

{

  index index.php;
  root  /home/body;

  if ($request_filename !~ (js|css|images|robots\.txt|index\.php.*) ) {
    rewrite ^/(.*)$ /index.php/$1 last;
  }
}

这是错误:

[emerg]: unknown directive "location" in /opt/nginx/conf/nginx.conf:35

任何人都可以帮忙解决这个问题吗？提前致谢.

如何在codeigniter中允许uri中的特殊字符(如:ä,é,î,ø,ù)

如何在java中以随机顺序打印数组？

例:

int [] myArray = {5,4,3,2,1};

打印时,结果可能是:

3 2 1 4 5

要么

4 3 2 5 1
