Place JavaScript data in an Input field [duplicate]

Solution 1:

Use the value attribute:

document.getElementById("prdtotal").value = "1.00";

document.getElementById() returns the actual DOM object (a handle/reference to the <input> element).

Also note your missing double quote before the closing parenthesis.

I would suggest you to take a look at the Mozilla Developer Network (MDN):

• HTMLElement: a reference of all attributes a (general) HTML element can have.

• HTMLInputElement: a reference of all special attributes an input element (e.g. <textarea>, <input>) can have.

Solution 2:

You've found the element using getElementById but you've not specified its the value property you want to set.

document.getElementById("prdtotal").value="1.00"
