Changing variable name using a loop

[viceyo]

Hi!

I'm new to Javascript and I'm trying to write a script in which I need to use diferent variable names. The names are used from here:

<img border="0" alt="Visit W3Schools!" src="052407-ektron-pmsa-authentication.gif" name="b1" width="26" ...

I have several images which go from b1 to b5 but I want to be able to change that. For example, to add or remove images with almost no code changes.

I use a javascript to change the atributes of the image. For example:

document.b1.width=50;

I would like to be able to use a loop to change the atributes from all images without having to use a code line for each one (for example with a loop, using a variable to change the name b1, b2...).

Thanks in advance.

hi ...

instead of using the name-attribute use the id:

[HTML]<img border="0" alt="Visit W3Schools!" src="052407-ektron-pmsa-authentication.gif" id="b1" width="26"/>[/HTML]
now you may use a function like this:

function set_width() {
    for (var i = 1; i <=5; i++) {
        var img = document.getElementById('b' + i);
        img.width = 'whatever_value';
    }
}
 

kind regards
