fenway Posted November 16, 2006 Share Posted November 16, 2006 I don't know what you mean by "pass an element a function". Link to comment https://forums.phpfreaks.com/topic/27491-question-about-arrays/#findComment-125736 Share on other sites More sharing options...
extrovertive Posted November 17, 2006 Share Posted November 17, 2006 Just do something like this.var obj = document.form.elements;and then loop through obj searching for a type that matches "text"and get the value of it.

fenway Posted November 17, 2006 Share Posted November 17, 2006 As was mentioned earlier, if you iterate though .length of this element, you should be able to get at the values.

fenway Posted November 21, 2006 Share Posted November 21, 2006 Your form field is called "friends[]", not "friends". Link to comment https://forums.phpfreaks.com/topic/27491-question-about-arrays/#findComment-127689 Share on other sites More sharing options...
