jQuery hasAttr checking to see if there is an attribute on an element [duplicate]

Question

How do you check if there is an attribute on an element in jQuery? Similar to hasClass, but with attr?

For example,

if ($(this).hasAttr("name")) {     // ... } 

Answer 1

var attr = $(this).attr('name');  // For some browsers, `attr` is undefined; for others, // `attr` is false.  Check for both. if (typeof attr !== 'undefined' && attr !== false) {     // ... }
