基本数组的东西 [英] Basic array stuff
问题描述
这是基本的，我用Google搜索但没有找到太多帮助。
我有一个文本元素字段数组。他们都需要具有相同的
名称。所以，让名字全部用[]或单独构建为
a [0]，[1]，[2]等等。括号需要在那里，因为我会
在PHP中使用$ _POST {''a'']获取它们的值作为数组。
我想做的是在javascript中设置个人的价值
元素，比如a [3]。我尝试了很多组合
1 - 将所有ID设置为
a）a
b）a []
c）单独作为[0]，[1]等。
2 - 使用document.getElementById
3 - 使用document.getElementsByName
任何时候我从名称创建和反对，然后尝试使用那个
对象，我得到对象没有属性在Firebug中。这是真的
我是否尝试obj.value或obj [i] .value。
所以，请，
1 - 如何设置id属性？
2 - 如何在阵列中访问或设置单个成员？
3 - 对于name属性，我应该使用a []或单独构建它们
或者就javascript而言无关紧要？
是的，这是基本的，但我一直在现在几个小时在圈子里
所以任何帮助都将受到赞赏。
This is kind of basic, and I googled but didn''t find much help.
I have an array of text element fields. They all need to have the same
name. So, let the name be either all with a[] or build individually as
a[0], a[1], a[2], etc. The brackets need to be there because I will
obtaining the values of them as an array using $_POST{''a''] in php.
What I want to do is in javascript set the value of an individual
element, say a[3]. I have tried many combinations of
1 - setting the ids all as
a) a
b) a[]
c) individually as a[0], a[1], etc.
2 - using document.getElementById
3 - using document.getElementsByName
Any time I create and object from the name, and then try to use that
object, I get "object has no properties" in Firebug. This is true
whether I try obj.value or obj[i].value.
So, please,
1 - How do I set the id attribute?
2 - How do I access or set an individual member in the array?
3 - For the name attribute, should I use a[] or individually build them
or does it not matter as far as javascript is concerned?
Yes, this is basic, but I have been going in circles for a few hours now
so any help will be appreciated.

_POST {''a''在PHP中。
