Question

I want to create a link with the following href attribute:

app\process?val=12000

but the value for the val parameter (in this case 12000) must come from the value of a textbox on the page.

I know that I can use $(#textbox).value() to get the value, but I need to change the link when the value changes.

Here’s an EXAMPLE of something you could try.

HTML:

<input type="text" id="text"></input>
<button type="button" id="button">Get Link</button>
<br/>
<a href="#">Test Link</a>

jQuery:

$("#button").on("click", function(){
    param = $("#text").val();
    alert("www.example.com\apps?val=" + param);
    $("a").attr("href", "www.example.com\apps?val=" + param);
});​

In the OP you have $(#textbox).value(), but there are a few things wrong with this. First the selector needs to be wrapped in quotes like $("#textbox") where textbox is the ID of the element. Also, .value() is not a function in jQuery and is actually .val()
