Changing text after an input field

Question

How do I change the "2 Year Subscription" to "2 year:" without losing the input field

<div class="radioOption subscription1Col3">
<input class="buyNow" type="radio" name="product2" value="6_0" checked="">2 Year Subscription</div>

Answer 1

This is relatively simple, and I'd suggest the following (though currently untested):

var input = $('.radioOption.subscription1Col3 input'),
    text = input[0].nextSibling.nodeValue,
    newText = text.replace(/ subscription/i,': ');
input[0].nextSibling.nodeValue = newText;

Or possibly this version might be preferred, since it leaves the adjusted text wrapped in a label element, which aids UI and makes it easier to target that text content in future:

var input = $('#inputID'),
    label = $('<label />',{'for' : 'inputID'})
    .text(input[0].nextSibling.nodeValue.replace(/ Subscription/i,': '));
input.parent().empty().append(input, label);

JS Fiddle demo .

This does, though, require the input to have an id attribute so that the label is semantically attached to that input .

Answer 2

另一种方法是更改textContent

$('.buyNow')[0].nextSibling.textContent = "New Content"

Answer 3

jQuery doesn't support accessing text nodes, only elements, so you would need to use the DOM methods in Javascript to access the text node:

var nodes = $('.radioOption')[0].childNodes;
nodes[nodes.length-1].nodeValue= '2 Year';

If you put an element around the text:

<div class="radioOption subscription1Col3">
  <input class="buyNow" type="radio" name="product2" value="6_0" checked="">
  <span>2 Year Subscription</span>
</div>

Then you can use just jQuery to access it:

$('.radioOption span').text('2 Year');
