Question

so, i have a website im building just for something to do.

I do not have a lot of experience with javascript but i want this link of code to apply to 4 buttons and it changes the src and whatever is between the square brackets based on what button it is.

function changehome(){
    document.images["homeimg"].src= "homelinku.jpg";
    return true;
}

Can anyone show me how this can be done, i expected it to be possible using the parentheses?

Answer 1

You can define function with parameters and pass their to the function:

<input type="button" onClick = "changehome('homeimg', 'homelinku.jpg')" />

…

function changehome(img, src){
    document.images[img].src= src;
    return true;
}
