Can not pass html array to JS

Question

Hi I'm having trouble sending html form array to JS. I have dynamic html form and some fields:

<div id="fields">
<input type="text" name="ppav[]" id="p" />
<input type="text" name="quantity[]" id="q" size="3" />
<input type="text" name="price[]" id="pr" size="10" />
<input type="text" name="sum" id="su" size="10" disabled="disabled"/>
<br />
</div>

in JS i tried using this function but getting undefined alert instead of result:

var welements = document.getElementsByName('ppav[]');
for (var i = 0, j = welements.length; i < j; i++) {
    var an_element = welements[i];
    alert(an_element.selectedIndex);
}

Why are you trying to pull selectedIndex from a text input? — Michael Berkowski

What did you expect? the selectedIndex property returns the index of the selected option in a select element. If you want the value of your input fields, try alert(an_element.value);
