The parent component should pass a callback to the children, and each child would trigger that callback when its state changes. You could actually hold all of the state in the parent, using it as a single point of truth, and pass the “selected” value down to each child as a prop. In that case, … Read more
You can use the eq method to reduce the matched set of elements to one at a specific index: $(this).siblings(“.bar”).eq(0).text() That will select the first element in the set. In your case, you could simply use prev, as the element you’re looking for comes directly before the clicked element: $(this).prev(“.bar”).text() The problem with the array … Read more
To hide an element, use: display: none; visibility: hidden; To show an element, use: display: block; visibility: visible; The difference is: Visibility handles the visibility of the tag, the display handles space it occupies on the page. If you set the visibility and do not change the display, even if the tags are not seen, … Read more
Calling .parents(“.box .something1”) will return all parent elements that match the selector .box .something. In other words, it will return parent elements that are .something1 and are inside of .box. You need to get the children of the closest parent, like this: $(this).closest(‘.box’).children(‘.something1’) This code calls .closest to get the innermost parent matching a selector, … Read more
You should be looking for the second tr that has the td that equals ‘ Color Digest ‘, then you need to look at either the following sibling of the first td in the tr, or the second td. Try the following: //tr[td=’Color Digest’][2]/td/following-sibling::td[1] or //tr[td=’Color Digest’][2]/td[2] http://www.xpathtester.com/saved/76bb0bca-1896-43b7-8312-54f924a98a89
Well… sure… just access the parent and then the children. node.parentNode.childNodes[] or… using jQuery: $(‘#innerId’).siblings() Edit: Cletus as always is inspiring. I dug further. This is how jQuery gets siblings essentially: function getChildren(n, skipMe){ var r = []; for ( ; n; n = n.nextSibling ) if ( n.nodeType == 1 && n != skipMe) … Read more
This is called the adjacent sibling selector, and it is represented by a plus sign… h1.hc-reform + p { clear:both; } Note: this is not supported in IE6 or older.
Tired of sys.path hacks? There are plenty of sys.path.append -hacks available, but I found an alternative way of solving the problem in hand. Summary Wrap the code into one folder (e.g. packaged_stuff) Create setup.py script where you use setuptools.setup(). (see minimal setup.py below) Pip install the package in editable state with pip install -e <myproject_folder> … Read more
No, there is no “previous sibling” selector. On a related note, ~ is for general successor sibling (meaning the element comes after this one, but not necessarily immediately after) and is a CSS3 selector. + is for next sibling and is CSS2.1. See Adjacent sibling combinator from Selectors Level 3 and 5.7 Adjacent sibling selectors … Read more
