Retrieving Tag Names with jQuery
Querying elements in jQuery provides access to various attributes, including the tag name. This guide explores effective methods for obtaining the tag name of a given selected element.
Obtaining Tag Names
The .prop() method allows you to retrieve the tag name using .prop("tagName"). Here are some examples:
jQuery("<a>").prop("tagName"); // Returns "A" jQuery("<h1>").prop("tagName"); // Returns "H1" jQuery("<coolTagName999>").prop("tagName"); // Returns "COOLTAGNAME999"
For convenience, you can create a custom function as follows:
jQuery.fn.tagName = function() { return this.prop("tagName"); };
This allows you to use:
jQuery("<a>").tagName(); // Returns "A" jQuery("<h1>").tagName(); // Returns "H1" jQuery("<coolTagName999>").tagName(); // Returns "COOLTAGNAME999"
Note that tag names are typically returned in uppercase. If you prefer lowercase names, you can modify the custom function:
jQuery.fn.tagNameLowerCase = function() { return this.prop("tagName").toLowerCase(); };
Examples with lowered tag names:
jQuery("<a>").tagNameLowerCase(); // Returns "a" jQuery("<h1>").tagNameLowerCase(); // Returns "h1" jQuery("<coolTagName999>").tagNameLowerCase(); // Returns "cooltagname999"
