如何获取跨度标签的值？

Question

I want to get the contents of a span tag but what I have isn't working. An alert shows an empty dialog box. I've tried the following but nothing works.

var test=$('#test').val()
var test=$('span#test').val()
var test=$('td span#test').val()

Can someone tell me what I'm doing wrong?

Answer 1

span elements do not have a value property.

Instead, use html() for the HTML or text() for the text nodes.

Answer 2

$('span#test').text()

will give you the text. val() is for the attribute value

Answer 3

You are correct almost, but instead of the val() to Need to say html().

 var test=$('#test').html();
 var test=$('span#test').html();
 var test=$('td span#test').html();

Answer 4

a span doesn't have a value attribute.

You should instead do the following

var test=$('span#test').html()

or

var test=$('span#test').text()

Answer 5

use this

var test=$('#test').html()

Answer 6

You should use .text() . .val() is only for input elements.

var test = $('span#test').text();
