How to Read the value in a hiddenField from javascript

Question

我想在javascript / Jquery的隐藏字段中读取一个值。如何实现？

Answer 1

try this

var value=$('#HidennfieldID').val()

value will hold the value of hidden field

Answer 2

It's the same as for a regular field:

document.forms[xxx].elements[yyyy].value

xxx is the name of the form, or its number. yyyy is the name of the element (or its number).

You can also use document.getElementById() to get either the form or the field.

Answer 3

Use the field name or id, eg

var fVal = $('[name="name"]').val();
var fVal = $('#id').val();

Answer 4

<input type="hidden" value="12345" id="ixd" name='ixd' />

var val = document.getElementById("ixd").value;

Answer 5

This an example to read and write value just with pure javascript.

<input type="hidden" id="field-id" />

<script type="text/javascript">
    document.getElementById('field-id').value = "your value which you want to insert";
    alert(document.getElementById('field-id').value);
</script>
