[RESOLVED] Dynamic field in a function (simple)

Copy linkTweet thisAlerts:
Feb 04.2009

I had a simple ajax function (note: this is not an ajax question) that was working fine:

[CODE]function ajaxFunction()

…

document.myForm.my_field_name.innerHTML = ajaxRequest.responseText;

…

ajaxRequest.open(“GET”, “/ajax/fieldlist.php?value=” + document.myForm.my_other_field_name.value, true);

[/CODE]

I want to make the fields dynamic, so I passed them in the function parameters, and now it isn’t working:

[CODE]function ajaxFunction(modifyfield,targetfield)

…

document.myForm.getElementById(targetfield).innerHTML = ajaxRequest.responseText;

…

ajaxRequest.open(“GET”, “/ajax/fieldlist.php?value=” + document.myForm.getElementById(modifyfield).value, true);

[/CODE]

Any help would be greatly appreciated. I’m very confused here.

@MrNobodyFeb 04.2009 — I have used this before and it works perfectly:
[CODE]var ele = document.forms['myFormName'].elements;
ajaxRequest.open("GET", "/ajax/fieldlist.php" +
"?" + encodeURI(ele['myFieldName'].name) +
"=" + encodeURI(ele['myFieldName'].value), true);[/CODE]
Naturally, if you already know what name you wish to use in the query string, then you don't have to go for the [B]name[/B] property. But, I wanted to show you how it can be done for when the field name is coming from a variable or when you are building a longer query string using a for loop.
