RE: JavaScript and text field

[Chen, Gin]

function check()
{
        var inputvalue = document.getElementById("item").value;
        alert( inputvalue );
}

dont worry that it says get element by id. it actually checks both name and
id.
another way to do it is:

function check()
{
        var inputvalue = document.getElementsByName("item")[0].value;
        alert( inputvalue );
}

Subject: JavaScript and text field


Hi, 

I have some problems to access a text field.

I have this JSP code:

<html:form action="criteria.do" method="post" onsubmit="javascript:check()">
<html:text property="item" size="40" />....

And want to access the value of the item field:

function check(){
        var inputvalue = document.all.item.value;
        alert(inputvalue);
        var inputvalue = document.forms[0].item.value;
        alert(inputvalue);
}

No of these variant runs. In an another application I have the 2 solution
and it works. Are there any depedencies between struts and JS?
