Simply JavaScript - Question on hasClass
I am trying to work some of the illustrated examples to get a better feel on how they function. Presently I am having trouble with a portion of the hasClass from page 88.
I retyped the code to be a simple function:
then in a html doc I have this:Code:function has(target, theClass) { alert(target.className); var pattern = new RegExp("(^| )" + theClass + "( |$)"); if (pattern.test(target.className)) { return true; } return false; }
If I understand correctly I thought target.className would get the class name of the element passed to it, thus I expected to have the function return True, but I consistently get False. I got False whether I put in an element with the class or without it. I then put the alert(target.className) in to see what the value was showing has and I get "Undefined". So presently I am not sure if I am doing something incorrect or it maybe that I don't have a proper understanding of className. Any help would be appreciated.Code:<body onload='has("h3", "red");'> <p class="red">I should be white background black text</p> <h7>no class</h7> <h3 class="red">Some class</h3> </body> </html>
Thank you.
