jQuery simple value get issue with .val()

问题

I have the following code:

$('.document').ready(function(){
   alert($('font.someClass').val());
});

Here is a Fiddle with it.

Does anyone know why I can not return the value of a font tag?

Am I to assume that you are not allowed to call the value or set the value of a font tag.

回答1:

.text() not .val() - .val() is for form elements.

回答2:

The val() method get values from value which exists for form elements (like input). You is looking to get the text from some DOM element, so use the text() method.

I updated your Fiddle here with the code:

$(document).ready(function() {
   alert($("font.someClass").text());
});

回答3:

This will get you the text:

$('.document').ready(function(){
 alert($('font.someClass').text());
});
