Question

I have a form with an input textbox and a button. When I click on a button I want to go to a different page depending on the value of the input textbox. For example:

<form name="frm1" id="frm1" action="page.php">
    <input type="text" name="txt_name" id="txt_name" value="simple text" />
    <input type="button" Onclick="redirect_to('page2.php/?id=8&input=this.txt_name.value')" value="Save" />
</form>

How can I get this value? Can this be done without using a function?

Answer 1

if you have something like :

<form>
  <input type="text" name="formelem" />
  <input type="button" />
</form>

you can put to the button :

onclick="redirect_to('page.php/?id=8&input='+this.form.formelem.value)"

you are on the button, so “this” will be the button and you need to get the form from which you can get the input

another way ( if you don’t need a form for another purpose ) would be to just put :

<input type="text" id="formelem" />
<input type="button" onclick="redirect_to('page.php/?id=8&input='+document.getElementById('formelem').value)" />
