I have a login form in struts and I want to have focus on the username field when the page loads.
I am using <html:form> tag and I cannot get this form using its name from javascript as document.formName.username .
How can I do this?

You should also paste the relevant code, i.e. your form with the textfield on which you're trying to transfer the focus to.asgs– asgs2011-03-25 12:47:34 +00:00Commented Mar 25, 2011 at 12:47

Assign an id to the input element that you want to focus on, then do:
document.getElementById("myInputId").focus();
Alternately, don't give it an id, and do:
document.getElementsByName("username")[0].focus();

We cannot assign id to the form like <html:form id="formName"> /so the best way to do this is to access a particular form in a sequence it appears. Same is the ssequence case for form elements. document.forms[0].elements[0]

@imran, no, id is set when you specify a name to your action in
struts-config.xml (use <html:html xhtml="true"> if your <html:form> doesn't render an id attribute.We cannot assign id to the form like

if you have <html:form action="/someAction"> and in your struts-config.xml, you've specified a name for that action (which points to an ActionForm) and your html declaration is <html:html xhtml="true"> and inside your form you have <html:input> (with name of "userName"), then you can do this in your javascript:
document.formName.userName.value;
else
document.forms["formName"].userName.value;
