I need to create a jsp form with javascript. The problem is to assign the data path.

Imagine $form.work = "Hello Work";

If I create the form with html:

<div id='workForm'> Work:<input value=${form.work}></input> </div>

The input will show the work value (Hello Work). But I need to create this div form with js, something like:

var oDiv = document.createElement('div');
oDiv.setAttributte('id', 'workForm');
var oInput= document.createElement('input');
oDiv.appendChild(oInput)
...

I tryed to add an attribute to the input like:

oInput.addAttributte('value', '${form.work}')

But it shows: ${form.work} not Hello Work

Can someone help me?

Thanks!

Try this,

var work = "<%=form.work%>";

or

var work = "${form.work}"
alert(work);

If the window/ System alert had provided what you need, then you can setAttribute("value", work) to the hidden field or the JSP element you needed.

You're close, you must use template literals (backticks) https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals

oInput.setAttribute('value', `${form.work}`)
