passing variables assigned from input box

[phub11]

Hi all,

I'm try to set up a hidden variable that takes the value of an input:

bFINALTEXT1 = document.createTextNode("Final:");
bFINAL1 = document.createElement("input");
bFINAL1.style.width="5em";
bFINAL1.type="text"
bFINAL1.name=compXY+'comp[]';
//bFINAL1.onblur=function(){getfinal(this.value);};
 
bMAX1 = document.createElement("input");
bMAX1.type="hidden"
bMAX1.name=compXY+'comp[]';
//
bMAX1.value=bFINAL1.value
 

As you can see, I had originally been using a function (getfinal) which works fine if I don't dynamically add duplicate inputs that get different values. To solve this problem. I was hoping that I could just copy the X.value across, but it doesn't work.

Any ideas?

Thanks in advance

At the time you are assigning the value to the hidden input, the text input has no value. And the expression bMAX1.value=bFINAL1.value doesn't provide a synchronise mechanism for run time.

So you would have to do it when some event is fired. onchange can be a good choice.

a.onchange = function() {b.value = this.value;}

I don't understand the purpose behind it, as at the end, you have two variables of same value, that can also be done at server end(?).
