How to get hidden field value in JavaScript
In JavaScript, you can use following two ways to get hidden field value in a form :
- document.getElementById(‘hidden field id’).value
- document.formName.elements[‘hidden field name’].value
See an example here…
<html>
<body>
<script type="text/javascript">
function printIt(){
alert(document.getElementById('abcId').value);
alert(document.formName.elements['abcName'].value);
}
</script>
<h1>Access Hidden value in JavaScript</h1>
<form name="formName">
<input type=hidden id="abcId" name="abcName"
value="Wall Street! Money Never Sleep"/>
<input type=button value="Get Value" onclick="printIt()" />
</form>
</body>
</html>
If the button is clicked, it will prompts the hidden field value “Wall Street! Money Never Sleep”.
