Get value from hidden field using jQuery

I have a <inpu开发者_Go百科t type="hidden" value="" id='h_v' class='h_v'> Using jQuery I want to alert the user to this value .

I am using

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

But its not working, any clues!

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

---

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();

---

This should work:

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

---

html

<input type="hidden" value="hidden value" id='h_v' class='h_v'>

js

var hv = $('#h_v').attr("value");
alert(hv);

example

---

var hiddenFieldID = "input[id$=" + hiddenField + "]";
var requiredVal= $(hiddenFieldID).val();

---

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

Closing the quotes in var hv = $('#h_v).text(); would help I guess
