children

I've trying to create custom text field using TextInput element (I need it to use validator and custom style). But I can't hide part of TextInput content expanding (see image). I have similar problem with other elements, while it have root item (container) what contains other items, childrens can be seen if they are placed out of container coordinates. How can I make childrens parts hidden if they're out of root container? There is the code, but it's actually just template, I've tried to uze z attribute, with no success.

children是什么意思呢？就是我们拿到组件内部的props的时候，有props.children这么一个属性，大部分情况下，我们直接把 props.children 渲染到 JSX 里面就可以了。很少有情况我们需要去操作这个 children 。 但是如果一旦你需要去操作这个 children 。我们推荐使用 React.children 的 api , 而不是直接去操作他。 虽然说我们大部分情况下拿到的 children 是合理的 react element 或者是一个数组，但是 React 有提供 api 去操作他，那么他一定是有一个合理的原因的。 打开 React.js 源码，找到 children Children: { map, forEach, count, toArray, only, } 这个 children 是个对象，这个对象里面有 5 个属性，这个 5 个属性看上去就跟我们数组的操作非常的像，前两个是最重要的，也就是 map 和 forEach ，就相当于一个数组的 map 和 forEach 方法，我们可以理解为意义是一样的，但是实际的操作跟数组的 map 和 forEach 会有一点的区别。 这里 map 是所有逻辑里面最复杂的一个。而 map 和 forEach 是差不多的，他们唯一的区别是一个有返回，一个没有返回，map 是通过我们传入一个方法之后

I'm passing a var el into a function. el contains previously grabbed element (using getElementById) and when I console.log el in the function I get the following: The problem comes in when I try to grab an element inside of the el using: el.getElementsByName('fname'); I get the error: Uncaught TypeError: Object #<HTMLDivElement> has no method 'getElementsByName' The getElementsByName() API is at the document object level. It's not an HTMLElement method. You could use querySelectorAll() instead: var fnames = el.querySelectorAll('[name=fname]'); It's not supported in older browsers however. 来源：

I have this code which is located on the search.php page and retrieves all the categories for each post and echo's out a link to the first category: $category = get_the_category(); //print_r($category); if ($category) { echo '<a href="' . get_category_link( $category[0]->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category[0]->name ) . '" ' . '>' . $category[0]->name.'</a> '; What I need to do is use a similar code but that gets the child-most/deepest category in the array? This is the array thats printed out: [0] => stdClass Object ( [term_id] => 170 [name] => ACS Series

I have a function which gets the ids of all children of a parent from my DB. So, if I looked up id 7, it might return an array with 5, 6 and 10. What I then want to do, is recursively find the children of those returned ids, and so on, to the final depth of the children. I have tried to write a function to do this, but I am getting confused about recursion. function getChildren($parent_id) { $tree = Array(); $tree_string; if (!empty($parent_id)) { // getOneLevel() returns a one-dimentional array of child ids $tree = $this->getOneLevel($parent_id); foreach ($tree as $key => $val) { $ids = $this

So my list looks something like this: <div="list"> <ul> <li class="page item">Parent 1 <ul> <li class="page item">Child of Parent 1 and Parent of Grandchild <ul> <li class="page item">Grandchild</li> </ul> </li> </ul> </li> </ul> </div> This is through Wordpress' list_wp_pages along with a custom CSS suckerfish-like dropdown CSS code. Nothing can be changed in the unordered list itself, so I need to find a way to add a CSS style to only child pages that are also parents (Child of a Parent 1...). I've been trying to add an arrow icon only to child pages that have child pages of their own. I

I got the following situation: I got a table structure like this: <tr> <td>text</td> <td>text</td> <td>text</td> <td><a href="#"><img src="#" /></td> <td><span style="display:hidden"><a href="#">e</a> <a href="#">e</a></td> </tr> What I'm doing with the following function is displaying the hidden span on hover of the table row. However it quirks whenever I hover the childElements inside the tr: the anchored image and the span itself. How can I fix this? // Reveal item options on hover $$('#financedata tr').invoke('observe', 'mouseover', function(event) { event.target.up().childElements()[4]
