![]() Other than that, when having a lot of stuff to perform a if/else is usually more appropriate, and if doing a lot of if/else/elseif checking, a switch/case is probably better. You could also do something similar to this, and there are many different ways to use a ternary: $(div)(300) Return someOtherVar or function //some does not have the class. A jQuery plugin that allows the user to bind keyboard shortcut events to any element and when a key combination is pressed, an event is triggered following that. In other words you can do: var some = $(some).length ? This returns something, so usually it's used like so: var some = someVar=true ? "it's true" : "it's false" You can also do: some = true ? "it's true" : null To ensure cross-platform compatibility, the snippet must be well-formed.The shorthand IF/ELSE you are reffering to is called a ternary operator, and it's not chainable in the same way as a IF/ELSE statements, nor is it chainable as a jQuery method, and there are some limits to it's use, you can however place one inside the other, like so: some = true ? someMore = true ? "it's true" : "it's false" : "it's false" ![]() For example, Internet Explorer prior to version 8 will also convert all href properties on links to absolute URLs, and Internet Explorer prior to version 9 will not correctly handle HTML5 elements without the addition of a separate compatibility layer. As a result, the elements inserted may not be representative of the original string passed.įiltering isn't, however, limited to these tags. During this process, some browsers filter out certain elements such as, , or elements. innerHTML property to parse the passed HTML and insert it into the current document. When passing in complex HTML, some browsers may not generate a DOM that exactly replicates the HTML source provided. When the parameter has a single tag (with optional closing tag or quick-closing) - $( "" ) or $( "" ), $( "" ) or $( "" ) - jQuery creates the element using the native JavaScript. In most cases, jQuery creates a new element and sets the innerHTML property of the element to the HTML snippet that was passed in. If the HTML is more complex than a single tag without attributes, as it is in the above example, the actual creation of the elements is handled by the browser's. What if other JavaScript frameworks also use the sign as a shortcut If two different frameworks are using the same shortcut, one of them might stop working. There are many other popular JavaScript frameworks like: Angular, Backbone, Ember, Knockout, and more. Elements being injected into a different document should be created using that document, e.g., $("hello iframe", $("#myiframe").prop("contentWindow").document). As you already know jQuery uses the sign as a shortcut for jQuery. ownerDocument matching the document into which the jQuery library was loaded. The few that do will have an explicit note on their API documentation page.Ī common use of single-DOM-element construction is to call jQuery methods on an element that has been passed to a callback function through the keyword this:įor explicit parsing of a string to HTML, use the $.parseHTML() method.īy default, elements are created with an. Please note that although you can pass text nodes and comment nodes into a jQuery collection this way, most operations don't support them. Elements will be copied from the array as-is and won't be unwrapped if they're already jQuery collections. A jQuery object is created from the array elements in the order they appeared in the array unlike most other multi-element jQuery operations, the elements are not sorted in DOM order. The second and third formulations of this function create a jQuery object using one or more DOM elements that were already selected in some other way. find() method, so $( "span", this ) is equivalent to $( this ).find( "span" ). Internally, selector context is implemented with the. When the search for the span selector is restricted to the context of this, only spans within the clicked element will get the additional class.
