php模板中的select控件的onchang事件代码不起作用,如下：
<script language="JavaScript"> function s_changed() //cjq add { alert("s_changed"); var index=document.forms['theForm'].s[].selectedIndex; if ((document.forms['theForm'].s[].options[index].value=='2') { alert("ok"); ... } }</script><form name="theForm" action="o.php?act=s" method="post"><table> <tr> <td scope="col">1</td> <td scope="col">2</td> </tr> {foreach from=$g1 item=g name="g"} <tr> <td>1</td> <td><select name="s[]" onchange="JavaScript:s_changed()"> <option value=" ">请选择</option> {foreach from=$s1_list item=s} <option value="{$s.name}" {if $s.name eq $s1}selected{/if}>{$s.name}</option> {/foreach} {/if} </select> </td> </tr>{/foreach}</table></form>
<html><head><script type="text/javascript">function fun(x){ var y=document.getElementById(x).value; alert(y);}</script></head><body>Enter your name: <input type="text" id="fname" onchange="fun(this.id)"><select id="select" name="s[]" onchange="fun(this.id)"> <option value=" ">请选择</option> <option value="1">1</option> <option value="1">2</option> <option value="1">3</option></select> </body></html> document.forms['theForm'].s[]
要写作
document.forms['theForm'] ["s[]"]
function s_changed(obj) { if (obj.value == '2') { alert('ok'); } }<select name="s[]" onchange="JavaScript:s_changed(this)">
