I have some php code that generates a random password. Next to a text box I have some text which says \"click to Generate a random password\".

I have some php code that generates a random password. Next to a text box I have some text which says "click to Generate a random password".

What I am looking to achieve is when the text in double quotes above is clicked that the PHP code is run and the generated random password is then pasted into the text box开发者_如何学运维 which is beside the text above in double quotes.

How could do this? I am thinking maybe jQuery but not sure how I would do what I want above.

Here you are... complete and working example :)
Put files 'index.html' and 'passgenerator.php' into same directory.

index.html

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title></title>
        <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
        <script type="text/javascript">
            $(document).ready(function(){
                $('#generate').click(function(){
                    $.get('passgenerator.php', function(data) {
                        $('[name=password]').val(data);
                    });
                })
            });
        </script>
    </head>
    <body>
        <form action="">
            <input type="text" name="password">
            <input type="button" id="generate" value="Generate password">
        </form>
    </body>
</html>

passgenerator.php

<?php
echo sha1(uniqid());
?>

either use ajax to call the script page that generates the password or like col. shrapnel says port the generating function to javascript (which is a better idea)

Example (with jquery using ajax)

$.get("/PasswordGenerator.php",function(password)
{
    $("#TextboxID").val( password );
});

where TextboxID is the id of the textbox u want the password to be added to.

Don't do it in php. Just do it in javascript. Here is a very neat tutorial that should show you the step by step instructions: http://www.mediacollege.com/internet/javascript/number/random.html

Patrick Evans is right. You can setup your form like this :

<input type="button" value="Generate" onclick="generate();">

And in section you have to define a function

<script type="text/javascript">
    function generate(){
$.get("/PasswordGenerator.php",function(password)
{
    $("#TextboxID").val( password );
});
}
</script>

Try this ajax call to get the content using ajax and display it on the div.

$("#generate").click(function(){
 $.get('url:to:urPHP',{

                    data:urData
                  },function(data){
                  $("#generatedPassword").html(data);
                  });

});
<input type="" id="generate" value="click to Generate a random password" />
<div id="generatedPassword">

<div>
