下拉值填充输入框

Question

I am having issues changing some code to work on another area but slightly different.

The example in this jsFiddle http://jsfiddle.net/rgin/A8Nxp/354/ shows the original code but now I need it do something different

I have list of years so when one is selected I need to the price to appear in the empty textbox beside it. Each option has its own price.

<div align="right">Year Required </div>
</td>
<td><span class="wpcf7-form-control-wrap years-required"><select name="years-required"       class="wpcf7-form-control wpcf7-select wpcf7-validates-as-required" aria-required="true">   
<option value="">---
</option><option value="00/01">00/01</option>
<option value="01/02">01/02</option>
<option value="02/03">02/03</option>
<option value="03/04">03/04</option>
<option value="04/05">04/05</option>
<option value="05/06">05/06</option>
<option value="06/07">06/07</option>
<option value="07/08">07/08</option>
<option value="08/09">08/09</option>
<option value="09/10">09/10</option>
<option value="10/11">10/11</option>
<option value="11/12">11/12</option>
<option value="12/13">12/13</option>
</select></span>  <span class="wpcf7-form-control-wrap price">
<input type="text" name="price" value="" size="40" class="wpcf7-form-control wpcf7-text wpcf7-validates-as-required" id="pricetwo" aria-required="true" />
</span></td>

EDIT price list

01/02 - £150

02/03 - £135

03/04 - £120

04/05 - £105

05/06 - £90

06/07 - £75

07/08 - £65

08/09 - £64

09/10 - £63

10/11 - £62

11/12 - £61

12/13 - £60

Just need help modifying the jQuery in the jsFiddle example to meet the needs above.

EDIT I can not change the value of the options as I am using Contact Form 7 plugin with wordpress. So require the prices to be in the jQuery. Example 01/02 selected £150 appears in text field.

Answer 1

1) I don't find any price value in your code.
2) But I think, you're trying to display the value of select element in the textbox

.val() Here I used to get the current value of the selected option/textbox.

change Here I have binded the change event with .on() event Handler attachment like

$('select').on('change', function(){
    $('#pricetwo').val($(this).val());
});

Here is the JSFiddle

Updates: The value of option, need not to be same as innerHTML.

so change the select values like this

  <option value="">---</option>
    <option value="1">00/01</option>
    <option value="2">01/02</option>
    <option value="3">02/03</option>
    <option value="4">03/04</option>
    <option value="5">04/05</option>
    <option value="6">05/06</option>
    <option value="7">06/07</option>
    <option value="8">07/08</option>
    <option value="9">08/09</option>
    <option value="10">09/10</option>
    <option value="11">10/11</option>
    <option value="12">11/12</option>
    <option value="13">12/13</option>

Here is an updated fiddle

Answer 2

You have to set price in value of each option in drop-down . for ex :

<select name="years-required" class="wpcf7-form-control wpcf7-select wpcf7-validates-as-required" aria-required="true">   
<option value="">---</option>
<option value="£150">01/02</option>
<option value="£135">02/03</option>
<option value="£120">03/04</option>
<option value="£105">04/05</option>
<option value="£90">05/06</option>
<option value="£75">06/07</option>
<option value="£65">07/08</option>
<option value="£64">08/09</option>
<option value="£63">09/10</option>
<option value="£62">10/11</option>
<option value="£61">11/12</option>
<option value="£60">12/13</option>
</select>

If you don't want to change your values, you could add an additional data- attribute (HTML5)

HTML snippet

<option data-price="£11.99" value="1">1</option>
<option data-price="£12.99" value="2">2</option>
and so on...

JQuery:

$('#payslips-required').change(function(){
    var selected = $(this).find('option:selected');
    var price = selected.data('price');
    $('#price').val( price );
});
