Question

我试图从特定形式获取元素的值。因为FOREACH我有100个表单..我可以获取Form name = 1表单名称= 10但我无法从特定表单中获取隐藏值。谁能帮我？感谢。

[% FOREACH k_bilgi IN k_bilgiler %]
<form name='[% k_bilgi.i%]'>
<input type="hidden" name="itemnumberi" value="[% k_bilgi.itemnumber %]" />
<input type="hidden" name="returndate" value="[% k_bilgi.returndate %]" />
<input type="hidden" name="title" value="[% k_bilgi.title %]" />
<input type="hidden" id="author" name="author" value="[% k_bilgi.author %]" />
<input type="hidden" name="branchname" value="[% k_bilgi.branchname %]" />
</form>
[% END %]

我的javascript代码（b将是1或10或40）

function gonderildi(b) {
var div1 = document.forms[i];
alert(div1)     // this works.
var a = document.forms[i].elements['itemnumberi'];
alert(a);  // this is not work..

Answer 1

document.forms[i].querySelector("input[name='itemnumberi']")

Answer 2

如果使用id属性，它会更简单，更强大。 ID的查询速度更快。您可以像这样更改代码：

[% FOREACH k_bilgi IN k_bilgiler %]
    <form name='[% k_bilgi.i%]'>
        <input type="hidden" id="itemnumberi_[% k_bilgi.i%]" name="itemnumberi" value="[% k_bilgi.itemnumber %]" />
    </form>
[% END %]

function gonderildi(b) {
    var div1 = document.forms[i];
    var a = document.forms[i].getElementById('itemnumberi_' + i);

Answer 3

我想，你需要传递索引..试试这个。

function gonderildi(b) {
var div1 = document.forms[i];
alert(div1)     // this works.
var a = document.forms[i].elements[0];
alert(a);  // It should work ..

如何从特定形式获取隐藏价值？
