![]() To ensure cross-platform compatibility, the snippet must be well-formed. 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. Elements being injected into a different document should be created using that document, e.g., $("hello iframe", $("#myiframe").prop("contentWindow").document). ![]() ![]() 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" ). For a runnable example, refer to the demo of the ImageEditor. Default Tools The ImageEditor creates a set of default tools for image editing. Internally, selector context is implemented with the. The ImageEditor provides a predefined collection of tools that are used to interact with the widget. The images are resizable and draggable: $('#objects img').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. Let’s start with the styling of the content and the image container: #contentĮvery time we drop a new image we insert it into the “images” array. We will also provide a delete icon to remove the element. In each item we will use a slider to allow the rotation of the respective element. The objects sidebar contains all the draggable elements and the tools area will show a list of all the used elements. The markup is pretty simple: we have a main container with the objects sidebar, the main image and the tools area:
