Get value from hidden field using jQuery

This should work:

var hv = $('#h_v').val();
alert(hv);

If you don't want to assign identifier to the hidden field; you can use name or class with selector like:

$('input[name=hiddenfieldname]').val();

or with assigned class:

$('input.hiddenfieldclass').val();

Use val() instead of text()

var hv = $('#h_v').val();
alert(hv);

You had these problems:

• Single quotes was not closed
• You were using text() for an input field
• You were echoing x rather than variable hv
