Changing text after an input field

问题

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>

回答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;

JS Fiddle demo.

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.

Another way will be to change the textContent

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

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');
