Do I really have to do sth. like this? That is one strategy, yes. On bi-directional relationships there is an “owning” and a “non-owning” side of the relationship. Because the owning side in your case is on Child, you need to set the relationship there for it to be persisted. The owning side is usually … Read more
The advantage of separating the child from the child css selector would only be if you’d like to use the parent for something else. Otherwise, it’s slightly faster to do it in one call, like expect(element(‘#parent_1 > .red’)).toBe(‘red’); since Protractor doesn’t need to make two calls to the browser in this case. Another reason to … Read more
Assuming that structure is static you can do this: var mainDiv = document.getElementById(‘mainDiv’), childDiv = mainDiv.getElementsByTagName(‘div’)[0], requiredDiv = childDiv.getElementsByTagName(‘div’)[1]; Further reading: .getElementsByTagName() (from MDN).
This can be done using the grunt-contrib-copy plugin. The main thing to note is that you can change the destination programmatically by using a rename function (which takes in the destination and source of each file). Here is a (somewhat brittle) sample Gruntfile.js that should copy to your desired structure: module.exports = function(grunt) { // … Read more
Create a property (or method) on FormOptions, say GetMyResult: using (FormOptions formOptions = new FormOptions()) { formOptions.ShowDialog(); string result = formOptions.GetMyResult; // do what ever with result… }
No. If the parent is killed, children become children of the init process (that has the process id 1 and is launched as the first user process by the kernel). The init process checks periodically for new children, and waits for them (thus freeing resources that are allocated by their return value). The question was … Read more
Because .children contains an HTMLCollection [MDN], not an array. An HTMLCollection object is an array-like object, which exposes a .length property and has numeric properties, just like arrays, but it does not inherit from Array.prototype and thus is not an array. You can convert it to an array using Array.prototype.slice: var children = [].slice.call(document.getElementById(…).children); ECMAScript … Read more
Update The below made sense for 2013. However, now, I would use the :not() selector as described below. CSS can be overwritten. DEMO: http://jsfiddle.net/persianturtle/J4SUb/ Use this: .parent { padding: 50px; border: 1px solid black; } .parent span { position: absolute; top: 200px; padding: 30px; border: 10px solid green; } .parent:hover span { border: 10px solid … Read more
The getParent method returns a ViewParent, not a View. You need to cast the first call to getParent() also: RelativeLayout r = (RelativeLayout) ((ViewGroup) this.getParent()).getParent(); As stated in the comments by the OP, this is causing a NPE. To debug, split this up into multiple parts: ViewParent parent = this.getParent(); RelativeLayout r; if (parent == … Read more
How about: $query = “SELECT p1.id, (SELECT COUNT(1) FROM post_table p2 WHERE p2.parent_id = p1.id) as num_children FROM post_table p1 WHERE p1.parent_id = 0”; or if you put an alias on the p1.id, you might say: $query = “SELECT p1.id as p1_id, (SELECT COUNT(1) FROM post_table p2 WHERE p2.parent_id = p1.id) as num_children FROM post_table … Read more
