HTML DOM Input Reset form property


The HTML DOM Input Reset form property is used for returning the form reference that contains the given reset button. If the reset button is outside the form then it will simply return NULL. This property is read-only.

Syntax

Following is the syntax for input Reset form property.

resetObject.form

Example

Let us look at an example for the Input Reset form property −

 Live Demo

<!DOCTYPE html>
<html>
<body>
<h1>Input reset form Property</h1>
<form id="FORM_1" style="border:solid 2px green;padding:2px">
UserName: <input type="text" id="USR"> <br>
Location: <input type="text" id="Age"> <br><br>
<input type="reset" id="RESET1">
</form>
<p>Get the form id by clicking on the below button</p>
<button type="button" onclick="formId()">GET FORM</button>
<p id="Sample"></p>
<script>
   function formId() {
      var P=document.getElementById("RESET1").form.id;
      document.getElementById("Sample").innerHTML = "The id of the form containing the reset button is: "+P ;
   }
</script>
</body>
</html>

This will produce the following output −

On clicking the GET FORM button −

In the above example −

We have created an <input> element with type=”reset”, id=”RESET1”. Clicking on this button will reset the form data. This button is inside a form that contains two text fields and the form also has an inline style applied to it.

<form style="border:solid 2px green;padding:2px">
UserName: <input type="text" id="USR"> <br>
Location: <input type="text" id="Age"> <br><br>
<input type="reset" id="RESET1">
</form>

We then created a button GET FORM that will execute the formId() method on being clicked by the user.

<button type="button" onclick="formId()">GET FORM</button>

The formId() method uses the getElementById() method to get the input field with type reset and gets the id property of the form object that contains the reset button. It then assigns this value to variable P and displays in the paragraph with id “Sample” using its innerHTML property −

function formId() {
   var P=document.getElementById("RESET1").form.id;
   document.getElementById("Sample").innerHTML = "The id of the form containing the reset button is: "+P ;
}
