JS secara otomatis menemukan menu drop-down pilih dan pilih (kode sampel)

复制代码代码如下:

function find_select (name)

{

var select = document.geteLementsbyname (name);

var find_str = document.geteLementById ('to_find_str'). value;

if (pilih)

{

SELECT = SELECT [0];

var child = select.childnodes;

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

untuk (var i = 0; i <len; i ++)

{

if (can)

{

text = anak [i] .text;

if (text &&

text.indexof (find_str)! =-1)

{

//console.log(text);

anak [i] .doSted = true;

var v = anak [i] .value;

SELECT.VALUE = V;

SELECT.Onchange (V);

is_end = false;

merusak;

}

}

if (anak [i]. Dipilih)

can = true;

}

if (is_end)

peringatan ('已没有匹配内容');

}

}

复制代码代码如下:

<tr>

<td> <? PHP gema $ l_specialactivityIdentifier?> </td>

<td>

<Pilih Nama = "Activity [Identifier]" ID = "Identifier" Onchange = "Change_Activity (this.Value)">

<Option value = ""> 请选择 </pection>

<? php

foreach ($ activitytypes as $ row) {

echo '<value opsi = "'. $ row ['identifikasi']. '" . $ Row ['name']. '</tipt>';

}

?>

</pilih>

-<input value = '' id = 'to_find_str' size = 16 style = "text-align: center;" /> <input value = 'find' onClick = 'find_select ("aktivitas [identifikasi]")' type = tombol />

</td>
