I want to create a invisible form anywhere into a HTML page dynamically using JavaScript and then submit automatically.
I want to create the form given below:
<form name='myForm' method='post' action='http://www.another_page.com/index.htm'> <input type='text' name='myInput' value='Values of my input'> <input type='hidden1' value='Hidden value 1'> <input type='hidden2' value='Hidden value 2'> </form>
I tried using the JavaScript below:
my_form=document.createElement('FORM'); my_form.name='myForm'; my_form.method='POST'; my_form.action='http://www.another_page.com/index.htm'; my_tb=document.createElement('INPUT'); my_tb.type='TEXT'; my_tb.name='myInput'; my_tb.value='Values of my Input'; my_tb.appendChild(my_form); document.body.add(my_form,document.body.elements[0]); document.my_form.submit();
But not working? How can I do that? Please help.
The task is to create an HTML form dynamically with the help of JavaScript. There are two approaches that are discussed below. Approach 1: Use document. createElement() to create the new elements and use setAttribute() method to set the attributes of elements.
If you want to dynamically add elements, you should have a container where to place them. For instance, a <div id="container"> . Create new elements by means of document. createElement() , and use appendChild() to append each of them to the container.
The values will be input.name and input.Create a function called handleFormChange. Assign this function to the input fields as an onChange event. This onChange event takes two parameters, index and event. Index is the index of the array and event is the data we type in the input field.
You're adding the form element as a child of the text box.
my_tb.appendChild(my_form);
Should be
my_form.appendChild(my_tb);
Also, I don't see where you're trying to create the hidden elements, but it's the same thing as adding a text box.
Another problem - trying to reference the form as document.xxx means that xxx is the name of the form. But anyway, try
my_form=document.createElement('FORM'); my_form.name='myForm'; my_form.method='POST'; my_form.action='http://www.another_page.com/index.htm'; my_tb=document.createElement('INPUT'); my_tb.type='TEXT'; my_tb.name='myInput'; my_tb.value='Values of my Input'; my_form.appendChild(my_tb); my_tb=document.createElement('INPUT'); my_tb.type='HIDDEN'; my_tb.name='hidden1'; my_tb.value='Values of my hidden1'; my_form.appendChild(my_tb); document.body.appendChild(my_form); my_form.submit();
var myform = document.createElement("form"); product = document.createElement("input"); product.value = JSProduct; product.name = "Product"; myform.action = "myForm.aspx"; myform.method = "post"; form1.appendChild(product); document.body.appendChild(form1); form1.submit();
This will create a form and which has a child element product ("Input type") you have to append child element to parent element like product to form and form to DOM root elemnt body and document and you can add atribut of the form as action and method this will do your thing.
