Jquery option setzen

Due to the way browsers interact with plugins and external code, the. We can retrieve several distinct values for a single element one at a time, or as a set:. The above lines alert the data values that were set on the body element. If no data at all was set on that element, undefined is returned. As of jQuery 1. The treatment of attributes with embedded dashes was changed in jQuery 1. The second statement of the code above correctly refers to the data-last-value attribute of the element.

In case no data is stored with the passed key, jQuery searches among the attributes of the element, converting a camel-cased string into a dashed string and then prepending data- to the result. So, the string lastValue is converted to data-last-value. Set the HTML contents of each element in the set of matched elements. Additionally, jQuery removes other constructs such as data and event handlers from child elements before replacing those elements with the new content.

As of jQuery 1. For example, Internet Explorer prior to version 8 will 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. In Internet Explorer up to and including version 9, setting the text content of an HTML element may corrupt the text nodes of its children that are being removed from the document as a result of the operation. If you are keeping references to these DOM elements and need them to be unchanged, use.

This method is not available on XML documents. For selects, checkboxes and radio buttons, you can use: When this value is sent to the server via XHR, however, carriage returns are preserved or added by browsers which do not include them in the raw value. A workaround for this issue can be achieved using a valHook as follows:. Get the single value from a single select and an array of values from a multiple select and display their values. Set the value of each element in the set of matched elements.

In this case, the input s and the option s having a value that matches one of the elements of the array will be checked or selected while those having a value that doesn't match one of the elements of the array will be unchecked or unselected, depending on the type. Setting values using this method or using the native value property does not cause the dispatch of the change event. For this reason, the relevant event handlers will not be executed.
