use id instead of name

[gecekule]

Hello,

use id="test1" and id="test2" instead of name="test1" and name="test2"

did not work: var ThisRadio = AllFormElements.name; => var ThisRadio = AllFormElements.id;

How do I run with id=""?

Thanks in advance

<SCRIPT LANGUAGE="JAVASCRIPT">
function RadioValidator()
{
    var ShowAlert = '';
    var AllFormElements = window.document.getElementById("FormID").elements;
    for (i = 0; i < AllFormElements.length; i++) 
    {
        if (AllFormElements[i].type == 'radio') 
        {
            var ThisRadio = AllFormElements[i].name;
            var ThisChecked = 'No';
            var AllRadioOptions = document.getElementsByName(ThisRadio);
            for (x = 0; x < AllRadioOptions.length; x++)
            {
                 if (AllRadioOptions[x].checked && ThisChecked == 'No')
                 {
                     ThisChecked = 'Yes';
                     break;
                 } 
            }   

            var AlreadySearched = ShowAlert.indexOf(ThisRadio);
            if (ThisChecked == 'No' && AlreadySearched == -1)
            {
            ShowAlert = ShowAlert + ThisRadio + ' radio button must be answered\n';
            }     

        }
    }
    if (ShowAlert != '')
    {
    alert(ShowAlert);
    return false;
    }
    else
    {
    return true;
    }
}

JavaScript uses the id attribute, PHP uses the name attribute. To use the id attribute in JavaScript simply write your code as:

var my_var = document.getElementById('some_id').value;

You can do it even easier if you're using jQuery by writing:

var my_var = $('#some_id').val();

that's a bit over simplified ! Javascript can access elements by name, though agreed, getting value by id is more direct.

I am sorry, I do not know English, do not fully understand.

Can be in something different instead of id="test1"? xxx="test1" ?

I use google translate, forgive me

Thanks

An HTML element's "id" attribute is used to identify the element inside a document. Every "id" in a document has to be different because the "id" identifies one element.

Elements that represent form fields have a "name" attribute that is used when the form is submitted.

All of the radio buttons in a group need to have the same "name". That is what makes them a group. They can't have the same "id", because that would break the rule that says all "id" attributes have to be different.

Indeed, but for beginners I always stick with the JavaScript = id, PHP = name.
