问题 I think that there is either an error in my code, or my PHP or Apache is set up incorrectly. When I submit a form with a hidden field in it, I do not get any data in my $_POST array...

HTML FORM <form action='/utils/login.php ' method='POST'> <table> <tr> <td colspan='2'> Login </td> </tr> <tr> <td> Username </td> <td> <input type='text' name='userid' value='' size='12' /> </td> </tr> <tr> <td> Password <

微信小程序--hidden不生效原因及解决方案

阅读更多关于微信小程序--hidden不生效原因及解决方案

微信官方文档里有提到说hidden是所有组件都有的属性，但我实际编码中发现并不是这样的！！！！例如如下布局： <view hidden="true" style="display:flex;flex-direction: row;"> <text>text1</text> <text>text2</text> </view> 你会发现 hidden 没生效。经我实验发现 hidden 元素对块状布局才生效，所以这段代码里导致 hidden 没生效的罪魁祸首是 display:flex 。把这个去掉就可以了。如果一定要用 flex 布局怎么办？其实这里想用 hidden 无非就是想影藏这个布局， display:none 也能做到隐藏。这里可以用一个取巧的方法，动态设置 display 属性，示例如下： <view hidden="true" style="display:{{hideview ? none : flex}};flex-direction: row;"> <text>text1</text> <text>text2</text> </view> 这里的 hideview 是在对应的 js 里是一个变量，由 js 来动态控制。后话 hidden 隐藏布局，虽然隐藏了，但是还是会占空间。 display:none 隐藏不占据空间。来源： oschina 链接：

How to find hidden properties/methods in Javascript objects?

阅读更多关于 How to find hidden properties/methods in Javascript objects?

问题 I would like to automatically determine all of the properties (including the hidden ones) in a given Javascript object, via a generalization of this function: function keys(obj) { var ll = []; for(var pp in obj) { ll.push(pp); } return ll; } This works for user defined objects but fails for many builtins: repl> keys({"a":10,"b":2}); // ["a","b"] repl> keys(Math) // returns nothing! Basically, I'd like to write equivalents of Python's dir() and help(), which are really useful in exploring new
