    Arrow var + var?

    Hi,

    I am new in Javascript... i would like to know if it is possible to get this result:

    I have this var:
    var test= document.forms.forms1

    i would like to complete it another var like:
    var test1= .name.value=""

    is it possible to do smth like:
    var test3= test+test1 ?

    I simply would like to specify only part of the code (document.forms...) and add the other part by using a different var, in the way to change it according to the situation. Is it possible?

    Thank you

    does this get close:

    Code:
    <body>
    <form name="form1">
    <input name="name" value="tom"/>
    </form>
    <script type="text/javascript"> 
    var test1="name"
    var test2="value"
    var test3=document.forms.form1[test1][test2];
    alert(test3)
    </script>
    </body>

    Hi,

    Yes.. it is exactly this...
    Is it possible to do in the way that a var test1 include both name and value?
    in the way that i will get the same result but just with one var?

    Thank you

    there's not a good one that I can think of. You could do something like this:
    Code:
    <script type="text/javascript"> 
    var test1="name|value"
    var test3=document.forms.form1[test1.split("|")[0]][test1.split("|")[1]];
    alert(test3)
    </script>
    but it's probably more trouble than it's worth.

    Being that all form elements have a value (or can be given one), you might find that this is more useful:
    Code:
    <script type="text/javascript"> 
    var test1="name"
    var test3=document.forms.form1[test1].value;
    alert(test3)
    </script>
    if not, maybe you could describe a little more what you are trying to do - there may be a simpler solution...

    Thank you for your answers!

    is it possible to put two var inside a If statement?

    es, to write smth like this:

    if ((var1 > 1) || (var2>1)) ...

    in only one expression (to put var1 and var 2 together).

    Thank you

    Hi,

    I understood that it is possible to write if (var1 && var2 >1)... and if i want to write "or"... Do i have to write if (var1>1 || var2>1) or there is also another way?

    thx!

    each condition has to be evaluated separately...

    Code:
    var1=3;
    var2=4;
    
    alert(var1>2 || var2>1);
    alert(var1>4 || var2>5);
    alert(var1>1 && var2>2);
    alert(var1>3 && var2>1);
