JS findet automatisch das Menü der Dropdown-Auswahl und Auswahl (Beispielcode)

复制代码代码如下::

Funktion find_select (Name)

{

var select = document.getElementsByName (Name);

var find_str = document.getElementById ('to_find_str'). Wert;

if (auswählen)

{

select = select [0];

var child = select.childnodes;

var can = false, text = '', len = child.length, is_end = true;

für (var i = 0; i <len; i ++)

{

if (kann)

{

text = child [i] .Text;

if (Text &&

text.indexof (find_str)! =-1)

{

//console.log(text);

Kind [i] .Selected = true;

var v = Kind [i] .Value;

select.Value = v;

select.onchange (v);

is_end = false;

brechen;

}

}

if (Kind [i]. Ausgewählt)

Can = wahr;

}

if (is_end)

alarm ('已没有匹配内容');

}

}

复制代码代码如下::

<tr>

<td> <? php echo $ l_specialActivityidentifier?> </td>

<td>

<select name = "Aktivität [Identifier]" id = "Identifier" Onchange = "Change_Activity (this.value)">

<Option Value = ""> 请选择 </Option>

<? Php

foreach ($ acityTypes als $ row) {

echo '<option value = "'. $ Row ['name']. '</Option>';

}

?>

</select>

-<input value = '' id = 'to_find_str' size = 16 style = "text-align: center;" /> <input value = 'find' onclick = 'find_select ("Aktivität [Identifier]")' type = button />

</td>

</tr>
