Question

Since I’m more versed in php thank in js I’ll try to explain what I need from a php perspective. I need to pass to a javascript function an array:

array('fieldname' => 'value', 'fieldname2' => 'value2' ...);

Thne the function would do this

foreach(array as k => v) {
  <input name='fieldname' value='value'/>
  <input name='fieldname2' value='value2'/>
  ...
}

I don’t know how to do this, I understand that js don’t have multidimensional array, so I wonder what is the correct way to do this in javascript?

p.s. I understand that there is a library that make available the php function to js, but I want to learn what is the best practice to do this in pure js.

Thank you very much

<script type="text/javascript">
// <![CDATA[

  // Create an associative array.
  var array = {'fieldname': 'value', 'fieldname2': 'value2'};

  for (var key in array) {
      // Create an input element and set its name and value.
      var input = document.createElement("input");

      input.name  = key;
      input.value = array[key];

      // There's no simple "insert an element right here"; you have to pick
      // where in the document to add the input box.
      document.body.appendChild(input);
  }
