在PHP中动态更改文本

Question

hey guys i am building a form in which i want when a user select an option from the dropdown menus a text to be displayed and calculate the price.

The dropdown menu is:

<select id="recipient" name="recipient" tabindex="6" class="selmenu">  
            <option value="staff">Site Staff</option>  
            <option value="editor">Editor-in-Chief</option>  
            <option value="technical">Tech Department</option>  
            <option value="pr">Public Relations</option>  
            <option value="support">General Support</option>  
        </select>

and the other dropdown menu is:

<select id="recipient" name="recipient" tabindex="6" class="selmenu">  
            <option value="one">1</option>  
            <option value="two">2</option>  
            <option value="three">3</option>  
            <option value="four">4</option>  
            <option value="five">5</option>  
        </select>

What i want to do is when the user selects something from the first and the second menu i want a textfield to change dynamically... can anyone point me the way?

Answer 1

only ajax/jquery could do that in combination of php step might be...

1. onchange of any dropdown make a ajax request to php script.

2. return the json response from php script

3. use this response to either manipulate your form or display data on page.

Answer 2

you don't need to use php for this, it can all be done with jquery/javscript

an example using jquery is below (i had to rename your second select as you had re-used an ID):

$('.selmenu').change(function() {
  $('#output').text($('#recipient option:selected').text() + ' ' + $('#recipient2 option:selected').text());
})

output is the id of your textbox.

on a select value being changed, output will be filled with the selected value in both select controls
